Title: Help with Moca backhaul - newbie

I am attempting to establish a Moca backhaul from my Netgear RBR50 to my two RBS50 satellites that I use as wireless AP. Attached is a wiring diagram that I wonder will work. (config 1) The Moca just connects to each router and satellite without a switch or network. Since the netgear says that I can just connect the router and satellites together via an ethernet cable in a star config, without a switch, I think it may. (https://kb.netgear.com/000051205/Wh...and-how-do-I-set-it-up-on-my-Orbi-WiFi-System) I dont know if the RBR50 assigns an IP address to the MOCA backhaul ethernet through the WAN connection.

The next question is if I connect the Moca network to my router, will that work? (second attached file, config 2) The router will assign a network address to each moca unit and now the backhaul will have a network.

The next question is if I want to connect a device on the RBR50's switch, will it work with config 1 or do I need config 2? In config 1, there is no network for the backhaul, I think.

Thanks. I am getting confused between the Moca issues and the netgear RBR50 issues.

First thought is that you seem to only require the cable signal for the cable modem, and you have sufficient coax paths for the ISP/modem feed to be physically isolated from the MoCA-infused coax; so I’d suggest reconsidering the current coax topology, possibly eliminating the amp (powered splitter) and definitely using a separate MoCA-optimized splitter for interconnecting the MoCA nodes.

Related:
MoCA topology choices:
MoCA AP+client vs dedicated pairs
splitter input-fed vs all outputs
MoCA-compatible splitter recommendations (… and warnings)
preferred MoCA filter: PPC GLP-1G70CWWS (Amazon US listing) … 70+ dB stop-band attenuation, spec’d for full MoCA Ext. Band D range, 1125-1675 MHz

Yes, of course! The splitter amp was there when I had cable TV and never removed it when I canceled cable TV. But since I dont have cable TV any more, its no longer needed. So do u recommend 1b or 2b (attached)

As for how to link the adapters and mesh nodes via Ethernet, Config 1 seems OK, provided all the mesh nodes are configured as APs only. Config 2 would be OK were you to remove the redundant link between the switch and main mesh node (and configure all the mesh nodes as APs).

That said, I don’t know if the Orbi’s have a topology requirement similar to eero’s, requiring all satellites to feed via a primary node. (eero’s would require Config 1, but also all configured as APs only)

Title: Spectrum EU2251 Modem and voice effected by MoCA?

Thinking about setting up MoCA between office/entry point and AV room.

Here's our current setup:

Current modem is an EU2251 (make unknown, but suspect ARRIS) provided by Spectrum. Have internet, cable and voice/phone service. Spectrum specs says it's DOCSIS 3.1 certified and supports up to 5 Gbps (our internet connection is 500 MBps). The frequency range is 158MHz to 1218MHz.

Our office is the location of the modem, main router (ASUS RT-AX88u Pro), and several desktop computers and other devices connect to the router via ethernet. All ethernet is cat 6.

The AV room which is currently linked with the office using a MESH setup with an ASUS Rt-AX3000 router in the AV room which supports a TIVO, ROKU, Denon receiver, and weather station via ethernet to the AX3000 (the TV gets all input from the Denon receiver and the TIVO is connected to the cable system and the output feeds to the Denon receiver). All ethernet is cat 6.

WiFi great over entire 3,000 sq ft single floor home. Other TVs and ROKU devices around the various bedrooms use WiFi connections although cable lines are available to all.

Have a lot of questions about how to set up the MoCA devices, splitters, and filters, but for now the issue is whether a MoCA setup would affect or be affected by the voice/phone functionality of the setup.

Any thoughts?

[Assistant]
Welcome to the forums @BobMc.

Consider using that RT-AX3000 in Media Bridge mode instead. You should have faster than (1GbE) wired throughput. And better WiFi for the rest of your devices too.

BobMc said:

TL;DR: yes-ish. As a workaround, install a 70 dB MoCA filter directly on the modem.

Once MoCA is working, wouldn’t it just be configured as an AP? (Or is there some other terminology within the AIMesh lexicon for that configuration, assuming “mesh” means “AIMesh.”)

Title: MoCA issues after tenant/suite split

Howdy all,

I have been using MoCA in my home for a few years. (TL-MC84 adapters.) A year or so ago I got an 8 way splitter and installed it in the demarc, hooking up 8 rooms together. I then stuck adapters in the rooms that I needed. I have both VDSL2 and Cable (failover with a Merlin router) - last month a new tenant moved into the suite downstairs, and now I get periodic disconnects. I caught one, and the MoCA adapter in my living room was "Disconnected" for about 20 seconds, then linked back up. It had a bunch of RX Bad on it.

Does that mean that the main adapter near the TC4400 modem might be having issues? Maybe having a 2 way splitter to the modem and MoCA adapter after that 8 way splitter is a bad idea? I checked the demarc, and when my ISP rewired the second modem in, they just disconnected one for downstairs and hooked a new line from the pole. I now have one less spot populated on the 8 way splitter..

Ethernet TX:

Tx Good: 4279428
Tx Bad: 0
Tx Dropped: 0
Ethernet RX:

Rx Good: 16142627
Rx Bad: 277
Rx Dropped: 0
GPIO: 0x0000027d

Insights/guesses appreciated. If I need to check my filters or replace cable runs or whatever, let me know where I should start.

Cheers,

[Assistant]

You’d want to check your modem diagnostics to assess whether the signal strength is within the recommended range. That said, the typical approach is to use an initial 2-way splitter to get the modem connected with as little path loss as possible, then a secondary splitter to service the remaining outlets. (And if operating a MoCA network, a 70+ dB “PoE” MoCA filter would be installed on the input port of the top-level 2-way splitter, and the secondary splitter would ideally be right-sized and MoCA-optimized.)

And if a splitter can’t be down-sized and has unused ports, a 75-ohm terminator should be used to cap any open ports.

Another possibility to consider is signal interference. You might look into replacing your “PoE” MoCA filter with a 70+ dB model, making sure the downstairs tenant’s connection is outside the scope of your coax.

Okay, I'm not really sure how to read the specs on these, but I think they don't meet the recommendations?
https://www.amazon.ca/Filter-MoCA-Cable-coaxial-networks/dp/B00KO5KHSQ/?tag=smallncom-20
https://www.amazon.ca/GLP-1G70CWWS-Filter-Eliminate-Multi-Room-Interference/dp/B08HJ4F4D4/?tag=smallncom-20

Can you point me in the right direction? I know that some filters are already on both incoming lines - whatever Shaw originally installed. I will get pictures later today.

https://www.amazon.ca/Pieces-Type-Terminator-Coaxial-Satellite/dp/B00JJYDU4Q/?tag=smallncom-20
So stick these on every disconnected port on the splitter, and any wall outlets without anything plugged into them?

I'll see if I can get line stats too.

BikeHelmet said:

So they did a new pull over to the demarc - that's interesting...

WIth CoxHSI here in San Diego - they would just have the one run over to the demarc, and split it there - the CPE (TV and/or Broadband) are provisioned at the MAC/SN level with two home runs - one to the primary, and another to the secondary...

I would look at signal levels for your CM, along with the MACA units...

Remember that a 2:1 split is a 3dB loss of signal...

Title: New MoCA 2.5 setup. Long run, many outlets & TV's etc.

I need some help with setup of MoCA 2.5, cable TV runs and an amplifier in a 100 plus y/o house. The existing cable TV input line from the street is an RG-11 line. Every other cable line on this property is RG-6. There is no existing Ethernet Infrastructure, and no practical way to do so in most every location here. That thick RG-11 line inbound from the street connects to an existing cable TV amplifier (presumably to drive all 10 of their TV’s and phones), and then out, through a MoCA -70 db filter, and on to various splitters and destinations. The splitters provide signals for digital telephone, television and Internet. We are replacing EVERY splitter we encounter, no matter the port count, with an Amphenol MoCA 2.5 (1675 Mhz) approved splitter. That’s working fine.

For the main house, after splitting off for telephony, we have 7 x 25’- 75’ “home run” cables that are run to each living space in the main house. Those 8 cables are all currently connected to an 8-way Amphenol MoCA splitter. 6 out 7 of those main house destinations now have a GoCoax adapter in place, and they’re working great. The 8th cable, a 175’ run, travels through an underground conduit to a separate building / wing that also needs MoCA and cable TV service.

Right now, that 175’ cable to the building / wing, connects / terminates directly to a 4 port Antronix “ARA 4-8” amplifier / splitter. Note that the 4 output connections go to 4 different locations in that wing, from 20’ to 100’ past that building / wing amplifier, and I’ll need to add a MoCA 2.5 device and run a TV at each of the 4 locations. (Again, this was all constructed this way by the cable TV provider).

Here’s my question: Based on the assumption that more TV signal was needed in the outlying building / wing, which would be the appropriate amplifier brand and model. PPC, Antronix, Commscope, etc., to pass both the amplified TV signal and unamplified MoCA signal down that building / wing line? This is new to me so I’m not sure which way to go.

[Assistant]
@krkaufman

You should do some calculations as well to estimate the signal drop from the each endpoint to the furthest other endpoints on the same backbone moca coax as it sounds like you might reach the moca modem amp limits. i think the upper limit on the modems is around 35-40dB of budget.
For the 175 ft run, i would look at terminating one end of the coax into a moca modem, ethernet to a switch, another ethernet from switch to another moca modem to allow that run to be just a point to point pair, thus minimizing losses. Downside is a slight increase in latency for going through the extra pair of modems. You should be able to use a 5 port Gbit switch since unless you have high bandwidth demand on the lan or have high bandwidth ethernet ISP drop, you will never saturate a Gbit lan link.

Hi DeGrub:

I understand the idea of bringing the MoCA signal off the Coax, through an Ethernet switch, and back onto the coax. That would accomplish getting a fresh repeated MoCA signal.

So the idea would be run the 175' from the main house with both the cable TV and MoCA 2.5 signals on board. Go through a 2 way splitter and offramp the MoCA 2.5 signal to an Ethernet switch, but keep the cable tv signal intact through the existing amplifier (which is only good to 1002 Mhz - but add a MoCA filter anyway?). Then on the other side of the existing amplifier for the cable TV signal, use only one of the 4 amplified outs (terminate the others) to it's own 2-way combiner(?) - one coming from an additional GoCoax MoCA 2.5, and the other the carrying the now amplified cable TV signal. After combining them, run into a 4-way splitter for home runs to the 4 additional locations?

Does that sound right?
Or should I get a different cable TV amplifier - and if so, which one?
And whose combiner should I use, or just a reverse a splitter and not worry about it?

The description of the setup lacks the details needed to make any specific recommendation (or suggest optimization alternatives), but if the secondary amp is actually required as described, you’d want it to be an amp designed to support MoCA to facilitate MoCA connectivity between output ports — and would potentially need a MoCA bypass setup akin to those described in section 3.7.1 of this MoCA Best Practices PDF. (like figure 10, but with the secondary amp in place of the downstream 2-way splitter)

———

Were such a thing available retail (see below), a MoCA/CATV diplexer would have been handy for the component fronting the secondary amp, to direct the MoCA and cable signals with minimized loss; barring that, a MoCA adapter with such a diplexer built-in could be used, but the preferred MoCA 2.5 adapters all lack this feature.

p.s. An elusive cable/MoCA diplexer:

Title: MoCa Packet Loss with TP-Link Equipment

MoCa Packet Loss with TP-Link Equipment
I am at a loss, and have nearly given up on Moca. I have a semi large network of iOT devices for the smart home. No issue and is stable.

But every 10 minutes or so my MoCa backhaul to the upstairs Switch and AP experience pack loss for a brief moment.

I have tested the MoCa between my laptop and the switch and i don't experience the packet loss. Its only when its between my switch and router. I have confirmed its not the coax because I'm using a different RG6 Short cable and experiencing the same behavior. The moca devices and network equipment all have the latest FW. This has been going on since day 1, over a year ago.

The only thing I can conclude is that there's a bug in MoCa that when there are may clients on the network it seems to fail. Because when I use it to connect a few clients I don't experience this when I tested it.

I added images of the Topology and the packet loss and equipment model #'s. Is there anyone that can help me get this to working correctly? Screenbeam support has not been helpful.

Tried:
Different Mocas Adaptors ecb7520
Short RG 6 Cable
New Terminations on Cat5 and RG6 cables
Limiting # of clients to under 40 that connect to the Switch and AP that Use the MoCa
Factory Resets on all ECB
Linksys MX4200 Routers (my original router / APs with the same behavior)
Tried FCA252 Mocas. Happens on both frequencies.
Used the SFP Ports on my Network equipment, PER TPLINK EEE isn't supported.
Also Disabled EEE protocal on all my network switches.

This is clearly an issue with MoCa or TP Link, I also notice. That if I click a website and having been using much BW in a while or suddenly want to goto multiple sites. I get pack loss or latency for like a few seconds and then it will start to work.

I truely believe this is simply a flaw and shouldn't be used as a reliable backhaul, what a waste of time and money.

[Assistant]
I have the EXACT same issue. Running TP-LINK Omada equipment and trying to use GoCoax moca devices. Packet drops every few minutes. 10-15 mins. Nothing wrong with the network setup as it is all business quality er7206, EAP773's, with OC200 controller, etc. Just would like to figure it all out without having to diagnose the entire coax network throughout the house. Xfinity 1.2gb service installed.

update!

I have isolated the Moca devices on the cable without hooked up to TPlink equipment. No packet loss of as long as I tested it. About 4 hours. Laptop on both ends with an assigned IP address. They can ping plotter each other all day without loss, so that excludes the Moca devices and the cable infrastructure as the culprit. I have to assume there is a flaw in the network design or a flaw in the network equipment making this packet loss occur with the Moca devices. Gocoax devices.

I get reliable 2.5G service from a pair of ScreenBeam ECB7250 units, but getting to that point was fairly frustrating. I've concluded that the ethernet chips in these things are not super compatible with all other equipment. I haven't seen any packet-loss problem, but what I do see with some connected gear is weird asymmetry in throughput rate on iperf3 tests: solid wire speed (2.35Gbps) in one direction, but a tenth of that (and very variable) in the other. I'm currently using them between a pair of Cisco CBS350 switches, and not seeing that issue, but I did see it before with a Zyxel switch and also with a Ugreen ethernet adapter. Swapping the two MoCA units didn't change which direction was slow, bolstering the idea that it's something about the connected gear not MoCA per se.

I also tried a pair of ASUS MA-25 MoCA adapters, and got exactly the same results, to the point where I suspect that both manufacturers are using the same chips.

Perhaps your problem is unrelated to my story, but it sure sounds like a similar "not as compatible as you'd expect for ethernet gear" issue. If you are using 2.5G MoCA adapters, you might try backing down to 1G adapters --- I suspect the bottom line here is that the NbaseT ethernet chips in these things aren't as mature as one would wish.

Title: Advice on correct splitter / IDing cables for MOCA 2.5 setup

Another MOCA newb in search of feedback. I'm migrating from Xfinity (cable) to AT&T 1 Gig Fiber - then planned to move to Sonic 10 Gig within a year - and fiber is going to be coming into a part of the house far removed from my office. It's not practical to run an ethernet cable from the entry point to my office; it's a rental and the owner does not want me doing any work whatsoever. WiFi 6E performance through two rooms and 1+ walls with wireless backhaul sounds disappointing, so MOCA 2.5 may be the answer.

Considering a pair of goCoax MA2500D adapters into the house cable from the room with the fiber entry point into the office, whence onto my ethernet LAN. The existing cable setup can be seen in attached photo. I expect the black cable going into the Antronix CMC2004H splitter is the Xfinity upstream. I'm not sure which cables I need, but presumably some testing with a laptop at the utility closet to my office, and then to the room with the entry point, can establish that if the cables themselves are good. Once I've established MOCA connectivity I would disconnect the upstream cable at the splitter to avoid signal leakage.

My main questions are:

- Am I missing something important?
- The cable appears to be RG-6/U - will that support MOCA 2.5 at full throughput?
- For my use case, it would make sense to directly connect the cable from the entry point room to the office cable in the utility closet and bypass the splitter entirely, since I have no need to route ethernet elsewhere at present, and no use for the rest of the house cable once I have connectivity to the office. Presumably a generic RG6 cable-cable connector would do for this?
- If direct connection wouldn't work, is the Antronix CMC2004H adequate to MOCA 2.5?
- Since I will be disconnecting the Xfinity upstream and there will be no possibility of leakage / interference outside the house, is there any point to installing a filter?

Thanks!

[Assistant]
N.b. while there is also a CAT5 patch panel here, there are actually no outlets for the phone/CAT5 wiring anywhere in the house. Presumably all those wires on the left are dangling somewhere inside the walls that nobody will ever know, since there is zero documentation of anything happening in this box.

Mine runs fine over a RG-59 and RG-6 combination of segments. No errors reported in the master adapter webUI. RG-6 will work for you... I would try to only use the existing coax segments you have to use and leave as much of the existing coax out of the network to minimize unseen cabling trouble... your existing splitters and amp(?) may not be MoCA-rated.

Yes, keep your MoCa cabling as simple and direct as possile. And use MoCa-rated coax splitters and use as few as possible to minimize insertion losses... -0.5dB per coupler, -3.5 or -7.0 for splitter outputs, etc.

oddhack said:
- If direct connection wouldn't work, is the Antronix CMC2004H adequate to MOCA 2.5?

That one may not be MoCA-rated for all of the MoCA2.5 frequencies. I solved this issue by getting the kit with the 2-way MoCA-rated splitters included... plus I preferred the Screenbeam/Actiontec adapters and Support documentation.

I would use a filter defensively, if possible, to prevent any possiblity of your LAN leaking out, even if not currently physically connected. Depending on layout and access, you may never know when someone with access might decide to connect up cables... you would want to defend against this... if possible.

I'm not sure, but Xfinity may have installed that in 2018 when I moved in. There's some sort of unused cable panel on the wall behind it that looks original (2007 vintage).

If I disconnect the upstream at the splitter a bad actor would have to break into the house to gain access to the cable network, at which point I'd have even bigger problems

Title: Best coax amplifier and splitters for MoCA 2.5 Ethernet?

I'm soon getting Fiber Gigabit Internet installed in my house (TDS Telecom in southern New Hampshire), with the ONT placed in my basement. I'll have a Cat 6 ethernet cable connecting the OTN to my router, but unfortunately, I have no wired Ethernet anywhere else in the house. But I DO have lots of coaxial cable jacks, and my router sits right next to one of them. So I plan to use the coax for Ethernet, and have acquired some ScreenBeam ECB7250K02 Bonded MoCA 2.5 Network Adapters.

My house's previous owners installed a Antronix VRA900 VoIP Residential Amplifier, and all the coax lines go through it. (Picture of mine further below.) On the front it says:

Antronix VRA900 VoIP Residential Amplifier
Output Ports 1-8
FWD: 52 - 1002 MHz 0 dB
RTN: 5 - 42 MHz 0 db

I am assuming I should remove that VRA900 and replace it with a MoCA rated amplifier. I see that Antronix makes a bunch of different MoCA Residential Amplifiers. Notably, the MVRAM902B/ACP-EZ (Midsplit 85/102 MHz) and the MVRA902B (42/54 MHz) seem very similar, but have DIFFERENT specs on the frequency ranges they forward vs. return. Which one should I pick and why? Are there other amplifiers I should pick instead? E.g., is the Amphenol IPA2008DSL2-RSVFA any better/worse? It's available through various 3rd party shops for around $110. I see the Antronix MVRA902B advertised for $50 on "antronix.myshopify.com".

I've also found at least three old 2-way splitters installed in various spots around the house. My ScreenBeam MoCA adapter came with a splitter, a Picolink 2-Way Splitter, part number 141-SP1XD-001, Frequency 5 - 1670 MHz. I'll probably need to buy more splitters. The Antronix MMC1002H-B 2-way splitter talks about supporting "MoCA 2.0"; but is that good enough for MoCA 2.5?

For 2-way splitters, I see that others have recommended either the Holland GHS-2PRO-M or Amphenol ABS312H. Is there any reason to use the more expensive Holland MSAT-2 2-2150 Mhz (intended for satellite TV) splitter instead?

Thanks in advance for your help and advice!

You should take a look at what frequencies MoCA uses.
From memory, none of the active equipment you mention is going to pass a MoCA signal.

Basically, you will need to isolate the signal to the MoCA devices. I have a single 2-way splitter on my incoming. One goes to cable, one goes to my modem.

If you can get the drop into the router isolated, you'll be good to pass the ONT ethernet through the MoCA to your router.
I do the same with a couple of managed switches for VLAN and two MoCA devices. I send the cable modem on one VLAN and the actual LAN over another.

GHammer said:

I am purposely NOT going to do that. From the Fiber ONT, I will run a Cat 6 Ethernet cable to the WAN port on my router. One of my router's LAN ports will connect to the ScreenBeam MoCA 2.5 adapter, which plugs into the coaxial cable in my house. I will place other MoCA adapters on coax jacks in my house as needed. The MoCA 2.5 network will be the Ethernet LAN in my house. The ONT to router connection for the WAN uplink will not use MoCA at all.

Thus my questions above are really about what hardware will make my MoCA LAN work best.

Reply to cross-posted Reddit thread, here.

copy/paste:
I'm assuming I should remove that VRA900 and replace it with a MoCA rated amplifier.
Ditto prior reply: absent any cable or OTA signal to distribute to multiple outlets, you don’t need an amplifier. You could replace the amp with a right-sized MoCA-optimized splitter; whether you’d use a splitter and the splitter size needed would depend on the number of MoCA nodes you want connected and your preferred topology.

MoCA topology choices:
MoCA AP+client vs dedicated pairs
splitter input-fed vs all outputs

I'll probably need to buy more splitters. The Antronix MMC1002H-B 2-way splitter talks about supporting "MoCA 2.0"; but is that good enough for MoCA 2.5?
Also ditto prior reply. The Picolink splitter should be fine; and the Antronix MMC1000 series splitters are a good choice for both MoCA 2.0 and 2.5, as the MoCA 2.x specs have the same frequency range and splitter requirements.

To the contrary, there are reasons to NOT use this splitter series: a splitter optimized for satellite has contrary specs to MoCA needs, high output port isolation at MoCA frequencies versus low isolation.

Title: Solved Frontier MoCA only getting 500Mb after upgrading to 1G.

I'm posting this in case it might help someone else. I couldn't find anything in the forums (sorry if I missed it). It may be obvious to others but it took me a while to understand.

I utilize my own router behind Frontier's router. Both run over MoCA. After upgrading to 1G, the Frontier router was getting the 1G but my router was only getting 500Mb.

I tried changing the MoCA settings but nothing worked, then it hit me that Frontier's setup was not only utilizing an external MoCA but also the MoCA of the Arris modem which is MoCA 2.0 not 2.5!

This is Frontier's setup:

The MoCA adapter is connecting the ONT to the Broadband port on the 25GW.
I didn't realize Coax #3 is the internal MoCA 2.0 feeding the local network.

The fix is to not use the modem's internal MoCA. That is unplug the coax from the modem and plug it into another external MoCA 2.5.
Plug that second MoCA's Ethernet into one of the modem's LAN ports.

[Assistant]
Yeah, the FCA252[25GW] MoCA WAN setup is a great workaround if all you have is coax.

One related thread: https://www.snbforums.com/threads/frontier-internet-and-moca.88947/#post-893214

I did see this post and the associated diagram in a few other posts, along with the frequency / mode breakdowns. It was never clear to me in a coax to ONT configuration that it was using the MoCA in the router as a separate band for the LAN side of business. Thank you for those freq breakdown posts as that is when it actually hit me. I was assuming the external MoCA unit Frontier has in their default configuration was doing both jobs.

Ah, ok. Yeah, just takes some thinking about it. The standard MEB1100 install (what’s pictured) couldn’t be doing both, of course, since there’s only a single Ethernet connection … to the router Ethernet WAN port. It isn’t helpful that the NVG468MQ/MEB1100 Install Guide doesn’t explain *why* the coax connection (3) is still needed between the splitter and router (beyond mentioning later that it’s needed for “TV services”).

Title: Thinking of deploying a MoCa 2.5 network, what else needs to be done?

Greetings!

I've been thinking about ways to get LAN connectivity throughout my apartment and so far, from what I've been able to gather, MoCa seems to be my best bet.
A bit of information:
- All walls are either brick or concrete, so digging into them to swap the coax for LAN cables is off the table. The existing coax runs have to be used.
- I am located in the EU (concerning equipment recommendation, but might be able to import what's needed from the US)
- The coax runs, end to end are rather long probably over 35-ish meters. Mentioning this, in case distance might be of concern.
- The coax cables and splitters are quite old (20+ years), not the best quality, although I used to have a DOCSIS 200Mbps internet connection for many years, prior to the current FTTH setup and signal was quite good.

In a nutshell, the idea is to opt out of the current coax TV provider and convert the apartment's entire coax network to a MoCa 2.5 internal network, then completely disconnect the external feed as it will no longer be needed (Switching to IPTV).
I have a separate symmetrical 1Gbps FTTH connection that enters the apartment and terminates to a PON modem, connected to a router and that router should be the starting point for the projected MoCa network (I've attached a rudimentary, kinda ugly, paint made diagram of the end goal).

For additional context (from the diagram), Room 1 is where main router is located and where the 1st MoCa adapter has to be, Room 2 houses a splitter where a TV used to be, got no plans to connect anything there anymore nor plug any RJ-45 devices, so no adapter needed. It's going to be just a coax connection point.
Rooms 3 and 4 are where MoCa adapters 2 and 3 should be connected, respectively. In Room 3, I plan to connect a second router for better Wifi coverage, while Room 4 will only have an IPTV box connected to the 3rd MoCa adapter.

The questions are, apart from 3x MoCa 2.5 adapters what else do I have to buy, to make the network run reliably and trouble free?
Which MoCa 2.5 adapters should I get and can I get them to work correctly, if I get them from the US?
Any other suggestions/ideas welcomed

[Assistant]
Is the coax in the wall RG59 or RG6 ?
If it is the old std UK coax cables for TV distribution, then may not work at all due to different impedance required for MOCA (75 ohm). Search other threads here about the issue.

I'm not in the UK, if that's of any meaning about what the cables might be.
How can I determine between the 2 or more types?

The coax should be embossed or have printing with the specification of type along with temperature rating of jacket or IEC compliance std, etc. Hopefully, you can access a 1 meter length somewhere as most cable i have seen has the marking at least every meter or less.

Title: Moca SFP transceiver: Magic-SFP

FYI, the Magic-SFP transceivers are now on sale for $125.

MaGiC-SFP™ : Solving the Last Mile Bandwidth Challenge V2 1.0G
MDSlink speed test
swginc.com

From my last exchange with SWG, they mentioned the adapter will only be able to do 1G with Mikrotik routers. I suspect that is due to the typical SFP+ negotiation of 1G/10G only.

The 1G limitation here (at least for Mikrotik routers) would mean Magic-SFP would behave similarly to a Moca 2.5 adapter with 1G ethernet port.

What's notable about this transceiver is its operating band starts from 400MHz rather than the usual 1125MHz.

Anyone intending to try this new transceiver?

[Assistant]
An interesting product. Why they don't use a MoCA adapter? Cheaper and can provide 2.5Gbps bandwidth.

I looked deeper at some of the presentation material.

Looks like the Magic-SFP uses Moca Access, whereas typical consumer devices use Moca Home.

That would explain why the transceiver RF band starts from 400MHz. It might not be compatible with typical consumer adapters.

Click to expand...
With changing the band filter, the normal MoCA adapter can run over 400-900MHz, as a MoCA Access CPE.
The quesiton is, who want to use MoCA Access. Looks like more and more ISPs are moving to fiber.

Title: Upgraded from GoCoax WF-803M to MA2500D - Not seeing faster speeds

I've had a pair of GoCoax WF-803M adapters on my system for about 5 years. Really happy with them and get right about at gigabit speeds on the wired connection with my Xfinity gigabit service (speed test is about 940 down and 118 up).

I recently got a newer XB8 modem that has a 2.5 Gb port on it as well as a new WiFi 7 mesh router that has 2.5 gig ports as well. So, I thought I'd "upgrade" to the GoCoax MA2500D since it has 2,5 gb ethernet ports on it vs the 1 gb on the WF-803M. I understand that both adapters are rated at 2.5 gig over the coax of course and in my house, there's probably some crappy pre-existing cable running through it. For any coax and connectors I had access to, I made sure to use high quality and RG-6.

Anyway, after changing the GoCoax boxes out, my PHY between them is maybe a little better, but no difference in speeds when testing on wired as well as 6E devices. Is this just a limitation of my internal house cabling? Or is there a setting perhaps I can use to boost? Not that gig speeds are bad at all for my use, but was just hoping to get much faster (like the 1.2gig speed test I get to my router from the cable modem) and faster within the house as well. Is the 8-9% boost in PHY rate all that is expected? Thanks!

PHY Rates with the WF-803M boxes (boxes 2 and 4...the others are TiVo Mini boxes connected via MoCA):

PHY Rates after installing the two MA2500D boxes (boxes 0 and 1):

[Assistant]
Yikes, those PHY rates between MoCA 2.5 nodes are awful. They should be near 3500 Mbps. Can you detail the coax setup?

Thanks for the reply. I need to update my home wiring diagram (slight changes since I last drew it up in 2019). I'm guessing I have some old crappy splitter (or splitters) in the wall or attic. I have access to the entry split and wiring and so on, but that "unknown" would be the only piece I can't detail.

I did just pop one of the older WF-803M boxes (#5 below in this table) on the coax in place of my host TiVo Roamio in my basement (which I know has a direct line to the splitter that my main MA2500D is connected to behind the router...box #0 below) and indeed I got that ~3500 rate. The office box #1 which is behind the mystery splits is still just around 1350.

Have you pulled the wallplates to see if the hidden splitters are in the outlet box(es)?

Title: Frontier FCA251/FCA252 networks limited to 2 MoCA nodes when operating at 1475-1675 MHz ?!?!

TL;DR: Frontier FCA251/FCA252 networks appear to be limited to 2 MoCA nodes when operating at 1475-1675 MHz

I went through several iterations of different combinations of 3 FCA252/FCA251 adapters, operating at 1475-1675 MHz, attempting connection:
any pair always connected if 3rd was powered off; (pic1, pic4)
powering and attempting to connect 3rd adapter always failed; (pic2, pic5)
powering off either of the connected adapters would allow powered 3rd adapter to connect. (pic3, pic4)
So it’s a 2-node-only limit for both the FCA252 and FCA251 (aka WF-803FT) adapters when operating at this upper frequency range, intended for a 2-node-only WAN connection:
FCA252[1GW]: 1475-1675 MHz
FCA251[WAN]: 1475-1675 MHz
I’d thought this setting would be useful for people trying to avoid DOCSIS 3.1 interference, but this node limit makes them mostly unusable outside the WAN intent.

.p.s. Reports indicate that the FCA252["25GW"] setting doesn't impose the same limitation, at least not a limit of 2.

CC: @gocoax

[Assistant] Dear @gocoax ... any feedback on this limitation for the FCA251 & FCA252 adapters? Any workaround to restore the default 16 node limit?

Title: New at Moca and need help. Will this work?

If you have questions about the diagram please ask. I need help. Will this work? I am going to use moca splitters.
Basically, will the two "outs" on the splitter be able to see each other and pass data? If not is there a device that will work in this situation? What is it called?
Thanks.
Jason

[Assistant]
Yes, it should work ... provided a 70 dB "PoE" MoCA filter is added to the input port of the top-level 2-way splitter in the junction box, to secure the MoCA signals inside the residence (and also provide a reflective performance benefit to the MoCA signals). A second MoCA filter may be needed, on the modem, if the modem exhibits sensitivity to MoCA signals.

Also, the diagram is a little confusing in the Bedroom: the modem will connect to the primary router "WAN/Internet" port, and the MoCA adapter would be connected to a LAN port on the same router.

Thanks @krkaufman
I noticed the diagram was mislabeled this AM. Thanks for catching that. And thanks for the related posts.
I may keep my current setup (which seems to work really well) but it is nice to know I have options.
regarding my current setup: I need to know if I need a POE filter if my setup does not have the moca adapters on the same leg of the coax as the modem? Can it bleed through the ethernet?

MoCA is designed to use port hopping (passing between output ports), as described in one or more of the above links; regardless, a simple splitter doesn’t have filtering that would block MoCA signals … which is why the prior reply said that you may require a second “prophylactic” MoCA filter to protect the modem, if the modem exhibits sensitivity to MoCA signals.

Title: Improving FTTP connection around the house?

Hi all, first post and I'm a network newbie so go easy on me please! I hope this is the right area for this post.

I just upgraded from 36mbps FTTC to 300mbps FTTP, but I'm getting quite a drop off in speed both in WIFI and ethernet across the network. Currently my setup is as follows:

Plusnet 300mbps installed behind TV in lounge, the router feeds a switch to supply TV, Xbox and various smart bridges, it also feeds a AV1200 TP Link powerline adaptor that is rated up to 1300mbps.

TV in Kitchen connected via WiFi
Computer in office upstairs connected via AV1200 powerline adaptor
Synology NAS in loft connected via AV1200 powerline adaptor

I've noticed that although I recieve a reliable 300mbps at the router, the computer is only recieving about a third of that speed and by the time you are upstairs the WiFi can be as slow as 20mbps and coverage is quite poor by the time you are in the garden/garage

Is there anything I can do to resolve these two issues?

Thanks!

[Assistant]
1. Throw away the power line adapters, they are junk and will at best hit 100-200 Mbps on a good day. The rating means nothing in the real world and it's just a marketing thing on the packaging.
2. You're in fact better off with WiFi than the power line adapters if you have a fairly recent router.
3. No mention of what WiFi router you have, but make sure it's not hidden behind something, as that is likely to reduce the range and speed. That includes it being behind the TV. Check that the antennas are screwed in properly and pointed upwards, but slightly outwards. If they're not screwed in properly, you might have damaged the signal amplifier in the router and it doesn't deliver the expected speed and range due to this.
4. Potentially getting a better WiFi router, something like a WiFi 6 model and placing it as centrally as possible to cover as much of your home as possible.
5. If it's your property, install some Cat 5e or Cat 6A (if you ever plan on going faster than 5 Gbps at home) cabling and run an Ethernet network, as it'll give you the best possible speeds around your house.

Any coax outlets around? If the coax is unused or if the needed frequencies are clear, and the lines are or can be interconnected using MoCA-compatible components, MoCA is a much more preferable alternative to extending the router LAN via wire than Powerline.

Separately, behind a TV may not be optimal placement of a critical wireless access point.

Title: Adapter for Co-ax cable tester

Hi all,

I'm new to MoCa and just planning an install. I live in a 1970s house in the UK. Lot's of old CoAx snaking its way around the house. I seem to have a Co-Ax wall socket in pretty much every room. They all seem to go up to the loft, where 4 of them are plugged into an old 4 port roof aerial amplifier (powered). There are another 3 cables just lying on the floor in the loft not plugged into the amp. What I want to do is find out which of these cables goes back to a Co-Ax wall socket in my garage (yes, I guess the original occupant wanted to watch analogue TV in the garage!). The garage is where my BT master socket and broadband modem/router is. I bought a network cable tester from Amazon which has ethernet plus a Co-Ax sockets on it. It's the kind that splits into 2. The problem I have is that the socket on the tester, which is female, is too tight in circumference to accept a male Co-Ax plug, like the kind that is commonly found on the end of an old Co-Ax cable. I've got a few adapters, and the only one that will fit is a short male to male cable, which seems to have a larger circumference than a regular Co-Ax male, so it fits onto the tester. I only have one of these though and I can't for the life of me identify it to buy another.

I've attached photos of the aerial amp in the roof, the tester main half with its Co-Ax socket, and the tester other half with my wide Co-Ax male short cable attached. Any advice gratefully received.

Once I know which cable is which, i can draw out my intended design.

Thanks all

[Assistant]
Tester appears to be BNC female, I think; so you’d need a BNC male to “whatever” adapter, where “whatever” is the connector type needed for your cabling and or wall sockets.

Or you could check for alternative testers designed for the task.

Thanks @krkaufman . Yes it is BNC female i think, but with a barrel size that won't allow a BNC male to be inserted into it. I'll look for a different tester.

Super cheap tone tracer… https://www.amazon.co.uk/RUANI-Finder-Generator-Network-Tracer/dp/B0BBT2QJ46/?tag=smallncom-21 … but should work, perhaps facilitated with a DIY adapter to more easily get the probes attached to the coax cable or outlet.

Title: Need help figuring out my Demarc to get Internet back upstairs.

Need some help, please. Before I can set up MoCA adapters, per the pics I attached, I need to remove the Directv line and plug the Spectrum line back in. I no longer use Directv, the the line with the orange stripe is a future fiber line that hasn't been dropped into neighborhood yet. Windstream is the DSL line that I also no longer use. Bedroom on first floor has live Spectrum coax and that is where my modem and mesh router currently sit. Can anyone help with what I should pull and what I should reconnect?

[Assistant]
Sketch a logical map of all if your coax runs including the brand and model number of splitters, amps, spectrum equipment, and your equipment of the current installation. Then provide an adjusted sketch for the future desired state. Then we may be able to help you.
Spectrum may be using DOCCIS3.1 which can severely limit your moca bandwidth if they have to share any coax runs.

BTW, most fiber drops i have seen do not require bonding and earthing. i suspect that orange marked cable is a RG6 coax drop from somewhere. Perhaps from a fiber end point somewhere to coax distribution in the neighborhood ? Who owns it ?

The fiber line is Ripple Fiber. Our neighborhood is completely wired, but the drop to the neighborhood won't be for a few months, hence my switch to Spectrum from DSL. When we moved here it was all SpectrumTWC, and we used TWC internet and had DirecTV installed. It looks like the DirecTV tech pulled out the line that goes to our upstairs and put in their splitter and run cable from dish on roof. There are a couple of loose cables. My guess is that I could simply pull the dtv cable and reconnect one of the loose cables. I'm hesitant because it looks like the now defunct DSL is connected to it for electrical reasons??? The splitter mentions DC power. I know there's a simple solution in terms of unplugging and replugging, because the first floor is getting Spectrum through coax. We only had DTV going upstairs because of their wireless system connected to the TVs on first floor. It was NOT doca.

Title: Can Verizon CR1000B work with other brand MoCA adapters?

I am considering connecting the two floors of my home via the existing coaxial cable using MoCA.
For that, I am considering using Verizon's CR1000B router that was given to me for free with the Verizon Fios installation as a MoCA adapter, so that I can buy just one other MoCA adapter.
I was wondering if people have tried any other brand adapters with CR1000B (or any other VZ routers, including CR1000A), and whether they play alone fine?

What brand(s) adapters would you expect to work with CR1000B?

Yet another option is to use CR1000B on the other floor as a MoCA-connected AP. Would it work as such?

[Assistant]
MoCA is standardized, so theoretically you can mix brands, except for one thing: there are two different signalling frequencies in the spec, and a lot of gear (including Verizon's IIRC) is hard-wired to use only one of those frequencies. So in reality it's at best a 50/50 shot whether two different makes of MoCA adapters will interoperate. If you want to go that route, you'd be well advised to get your other MoCA adapter from Verizon.

Also, while there's not a lot of info in Verizon's manual about that MoCA port, I suspect that it's the older MoCA 2.0 standard which is limited to 1Gbps or so. If I were you I'd spring for MoCA 2.5 adapters (2.5Gbps), which were going for about $150 a pair last I checked. (Even if your LAN is otherwise just 1Gbps, I'd recommend this because the extra speed helps make up for MoCA being only half-duplex.) I've had decent results with both the ScreenBeam ECB7250 units and the ASUS MA-25 units, with a slight edge to the former because they boot up faster.

I wouldn't bet on being able to get any use out of the CR1000B as an AP. I have the CR1000A which is allegedly functionally identical, and I gave up on it after awhile because its configurability is so minimal. It seems like nice kit hardware-wise, but the firmware is mighty dumbed-down.

What?!?! Can you be more specific?

Pretty much all retail MoCA 2.5 adapters interoperate, including the MoCA 2.5 adapters offered direct from Frontier (and available via eBay at $30 per); and so all are compatible with the built-in MoCA 2.5 LAN bridges available in the Verizon CR1000A/B units.
MoCA adapters, grouped by throughput

As for using the CR1000A/B units as APs, they can likely be dumbed-down to effectively just APs w/ MoCA bridges as has been possible with older Verizon routers, but there’s also the CE1000A, an extender(AP) with built-in MoCA bridge.

StR said:
Yet another option is to use CR1000B on the other floor as a MoCA-connected AP. Would it work as such?
If you already have a primary router with a built-in wireless access point, yes, it would seem to make more sense to install a standalone MoCA 2.5 adapter at your primary router as, effectively, the MoCA access point to which the CR1000B-as-AP could link via MoCA.

Exactly what adapter to buy may also depend on your subscribed throughput and whether you have 2.5 GbE gear.

Title: Do I need a PoE Filter?

I have a friend who wants a better WiFi signal in his detached Garage, on top of the garage he has an OTA Antenna.
The Antenna's coax cable comes down into the inside of the Garage, is connected to a coupler and then that cable is buried and goes about 30 feet into the inside of the house.

His ISP is Spectrum and that coax cable is located inside the office in his home and is directly connected to his Modem. Is the ISP coax cable the only location that I need to place a PoE filter?
Or do I also need to place one on the OTA antenna's coax cable. See diagram below of what I think needs to be done.

[Assistant]
PoE - Power over Ethernet!
Are you powering the MoCA boxes using PoE, in which case you would need an injector (not a filter) on the ethernet leading to each MoCA device.
*Im in the UK so MoCA is incredibly rare here, so if I'm wrong I will yield!

rpmartinez1987 said:
In this case I meant a Point of Entry filter.

You only have to consider the PoE filter for the demarcation point - where the CableCo run enters the house.

and only if you are putting MOCA signals on that piece of coax, either directly attached or via a splitter.

Title: Homeplug AV2 with longer distances over 400'

Hello all - Got a question about Homeplug AV2 and longer distances - in the 400'-500' range.

What I am looking for is low bandwidth communication from a ground solar system to my house where the overall distance is over 400'. I am not concerned about any significant bandwidth but do care about a reliable connection.

Here is the problem I am trying to solve.

Remote ground solar system is over 400' from the main service panel. The ground solar system has 80 Enphase microinverters. Up at the house I have an Enphase Envoy-S unit - this unit uses a primitive form of power line communication to communicate to the microinverters - getting power generated, updating firmware, and other communications. It has both wired and wireless ethernet to then communicate all that data via my router to Enphase's WWW servers. I don't know exactly what it uses for its powerline technology but given the length of time these units have been on the market it must be significantly older technology. And over that distance, the communication from the Envoy-S unit to the microinverters is poor to nonexistent.

My idea is to flip the problem around - move the Envoy-S unit as close as possible to the microinverters by installing it right on the ground mount in a NEMA 4X box and wire it into the solar subpanel. Then rely on Homeplug AV2 units to provide the ethernet down to that remote site connecting to the Envoy-S - my thinking is current powerline technologies must be far superior to whatever Enphase is using.

Thus wondering if anyone has any experience using Homeplug over longer distances.

The 400' run from my main panel to the solar subpanel is via parallel 4/0 AL cable and total voltage drop is in the 1.4% range.

Here is a line diagram describing.

main panel -- 15amp breaker -- AV2 on dedicated circuit -- router
|
----------- -- 100amp breaker -- 400' parallel 4/0 AL -- solar subpanel -- 15 amp breaker -- AV2 -- Envoy-S

Thanks in advance.

Up at the house I have an Enphase Envoy-S unit - this unit uses a primitive form of power line communication to communicate to the microinverters - getting power generated, updating firmware, and other communications. It has both wired and wireless ethernet to then communicate all that data via my router to Enphase's WWW servers. I don't know exactly what it uses for its powerline technology but given the length of time these units have been on the market it must be significantly older technology. And over that distance, the communication from the Envoy-S unit to the microinverters is poor to nonexistent.

My idea is to flip the problem around - move the Envoy-S unit as close as possible to the microinverters by installing it right on the ground mount in a NEMA 4X box and wire it into the solar subpanel. Then rely on Homeplug AV2 units to provide the ethernet down to that remote site connecting to the Envoy-S - my thinking is current powerline technologies must be far superior to whatever Enphase is using.

Thus wondering if anyone has any experience using Homeplug over longer distances.

The 400' run from my main panel to the solar subpanel is via parallel 4/0 AL cable and total voltage drop is in the 1.4% range.

Here is a line diagram describing.

main panel -- 15amp breaker -- AV2 on dedicated circuit -- router
|
----------- -- 100amp breaker -- 400' parallel 4/0 AL -- solar subpanel -- 15 amp breaker -- AV2 -- Envoy-S

Thanks in advance.

Use fiber optic cable and ethernet or serial communication. technology is well developed and reliable. Use it all the time with SCADA systems.

In retrospect I am kicking myself for not thinking of this when I had the trench 0pen, it would have been easy to add an empty 1-1/4" conduit the entire length down there when I put in the 3" conduit. But the reality is that stuff is all buried and due to location (steep grades, rocks, and erosion control) it would be expensive and time consuming to dig a new trench to run low voltage communication line down there.

So I'm looking at two possible solutions. Easiest and lowest cost would be Homeplug AV2 but no idea how it works over 400'+. The second would be a repeated RF solution since I don't have line of sight thus would have to have a midpoint repeater powered by the pool electrical.

I'll pick up some Homeplug AV2 units and try them out and report back if they work or not.

Technically it's possible - max run length for Home Plugs is around 300 meters, at least according to spec...

Some info here...

Title: MOCA 2.5 - Asymmetrical speed

Posted this on reddit but i don't expect much from there for reasons i won't get into.

I have 2 new GoCoax MA2500D MOCA adapters with 2.5GBE switches, cat 6 cable and 2 machines running RTL8125b 2.5GBE network cards.

The problem I'm having is that transfers to the file server write at close to 210MB/s (not great, but good enough) but the read speed is terrible at only 50MB/s.

I have turned off EEE on both machines, MA2500D updated to latest firmware. The MOCA splitters in use are wideband and explicitly MOCA compatible. One holland 3-way moca splitter with a POE filter outside the house, one "starburst" moca compatible 2-way indoors.

I don't expect mega speeds when reading and writing are occurring at the same time, but what could the issue be?

Here's what I tried so far.

LOOOONG ethernet cable wiring both machines together = full 2.5gbps speed in both directions.
LOOOONG ethernet cable connecting both 2.5Gb switches together = full 2.5gbps speed in both direcitons
Both MOCA adapters plugged directly into each machine, same problem.
I powered off my cable modem, same problem.

PHY rates in the UI are perfect:
PHY rate (0-1): 3523
PHY rate (1-0): 3531
PHY rate (0-0): 696
PHY rate (1-1): 693

No bad packets

Iperf3 bears out the issue. Using 5 threads with (-P 5):

Client -> File server 2.34 Gbits per second
File server -> Client 556 Mbits per second.

This basically matches what I am getting manually transferring files or running AJA.

Client -> Fileserver: 215 MBytes per second (write)
Fileserver -> Client: 55 MBytes per second (read)

I have seen a couple posts discussing this topic but no one seems to have any answers. Hoping someone has a fix.

[Assistant]
Your moca network seems fine given the sync rate. Your issue is likely the server read/write or client r/w or protocol used (SMB ?) . The iperf tests should be running from memory only, so disk access would not be in play . Try -p 10 and run it in both directions using reverse switch setting.

When you write 2.5 Gb/sec on the long ethernet cable test - that is the link rate shown for the interface ?
If so, that has nothing to do with the transfer rate except to set an upper bound.

Yes this is using SMB. What bothers me is that with both machines connected via ethernet (no MOCA) the transfer rate is pegged at 290-300 something megabytes a second which is what the drives in the file server can do.

-P 10 shows good speed, close to 2.34gbps with a fot of fluctuation but frankly this is not of any use if the file transfers themselves are extremely slow in day to day work. For example, 50MB/s is just not enough to use files live off the file server.

That 2.34 Gb/s is a saturated 2.5 link.
if you need real time access in the file, then use direct attached storage as that is the cheapest way to go. TB4 or 3 or maybe a local nvme array if you have enough pci lanes and bandwidth left available.

Title: MOCA adapters worked great for 2 days, now “unidentified network” for Ethernet.

I have tried many different potential fixes on my PC. command prompts such as ipconfig /release, /renew, /dnsflush, etc. Troubleshooter, device manager -> Network Adapters. Control panel options, network & ethernet, even did a factory reset on my computer including a disk clean. Nothing works.

Ethernet doesn't work on my Xbox either. it all comes down to the same issue: Can't connect to DHCP server. Both the xbox and PC show that an ethernet is connected, but it isn't getting internet from it.

I don't get it, because I set this MOCA up 2 or 3 days ago and it has been working amazingly. Speeds have multiplied a bunch. I am using the Screenbeam ECB6250. All of the lights on both adapters are the same as they were when it was working. Solid light for power, blinking light for coax (blinking light = processing data to my understanding) solid green light for ethernet in the room, blinking light for ethernet at modem.

I get on today and out of nowhere I am having this issue, even though everything appears the same. I have tried different ethernet cables as well to no avail. Wifi still works the same as it did before (good at other parts of the house, not good where I am trying to use MOCA/ethernet)

Does anyone have any idea? I think I’ve ran out of YouTube videos and blogs to watch for potential fixes.

[Assistant]
Green light on ethernet just means a valid hardware connection at 1000 Mhz.. Check the port lights on your PC. Should be two - one is the link rate (green=1000Mhz, orange=100) and the other is the activity light, blinking = packets being transferred .

turn off both moca adapters. Power one on, and then the other. Any change ?
You are getting active access to the internet by Wifi from ISP wireless router/modem ?

Are there any other moca modems connected on the coax ?
Do the Screenbeams allow you to set a security code ? If so, did you ? You might have to factory reset them.

Title: Intermittent packet loss on MoCA 2.5 network

Please help me solve this long-term problem I've been having on my MoCA 2.5 network!

I have 6 GoCoax 803M MoCA 2.5 adapters throughout the house and they are connected in the following way:

I am not using any FIOS set top boxes or routers. The UniFi Router is a Dream Machine Pro. The Tivo DVR has MoCA switched off in settings and is communicating with 5 x Tivo Minis throughout the house via ethernet (over MoCA).

My problem is that I'm experiencing intermittent packet loss on all of the adapters that is severe / prolonged enough to drop the connection between the Tivo Mini and the Tivo DVR.
[I tried adding another POE filter just in front of the DVR just in case, but it made no difference.]
[I also tried swapping out the Tivo system altogether with a Fios DVR, with remote connections via the FiosTV app on AppleTV - exactly the same problem of intermittent lost connection to the DVR. Interestingly all streaming apps work fine (including the FiosTV app streaming from the cloud rather than from the DVR - presumably due to a larger/longer buffer.]

The problem does not occur if I direct connect a Tivo Mino to the Router with an ethernet cable. In addition, the problem does not occur when I replace all of the MoCA 2.5 adapters with MoCA 2.0 adapters.

I have gone through the coax cabling as best I can to look for faults. I found one short run of RG59 which I replaced with RG6. I found a length of RG6 that had damage to the outer sleeve and replaced it. I have replaced the RG6 connection between the two splitters (about 40-50 feet apart) with RG11. I have replaced both splitters. And I have reterminated basically every cable end with new f-type connectors.

It hasn't made a bit of difference.

Other than knowing the problem persists by my Tivo minis dropping their connections randomly (typically every 5-20 minutes), I can also visualize the problem with Ping Plotter by pinging the adapters once every second:

(Note that PingPlotter directly connected to the 192.168.1.53 adapter - hence lower latency and no packet loss).

Any help or suggestions would be gratefully received, but specific questions would include:
- Does this look like an ongoing coax problem? Should I continue replacing every length of coax in the house?
- Would / could MoCA amplification help? (The last two adapters have a further ~50 foot cable run from the second splitter).
- Could it be a setting on the MoCA adapters themselves?
- Could it be a problem outside the MoCA network (this seems less likely to me).

[Assistant]
Only thing obviously shifted from recommended topology is the orientation of the initial 3-way splitter.

Recommendation would be:
* input port connected to ONT coax, with…
* “PoE” MoCA filter directly on input port;
* TiVo DVR line connected to low-loss splitter output (via MoCA adapter pass-through);
* MoCA adapter and secondary splitter lines connected to other outputs.

THANK YOU for taking the time to read and respond.

That's basically how I started out. I've recently tried 3 different orientations of that splitter in an effort to reduce point to point dB loss according to my "link budget":

I found that:
Orientation #1 gives me ~3500 Mbit/s between all points (despite the theoretical increased signal loss)
Orientation #2 gives me ~2500 Mbit/s beween Moca2 and Moca5 / Moca6 (which are both physically furthest away)
Orientation #3 causes loss of certain TV channels

I've just reconfigured that splitter back to orientation #1.

Is there a reason you suggest connecting the TiVo DVR line to the low-loss output on the splitter other than to preserve the quality of the TV signal?

Should you run RG11 cable straight to the receiver? - The Solid Signal Blog
Here's a tip that budding commercial installers will want to know about.There's a special type of cable that makes installs easier... but only if you use it right.
blog.solidsignal.com

That short piece of RG11 may be hurting you as much as it might have helped, particularly if you violated the minimum bend radius getting out of the wall. Good chance you are getting insertion reflections that don't die out since it is so short.

Also, search for a "unity gain" or "0 loss " amplified moca 2 certified splitter for your two splitters. You have a lot of dB loss across those paths between the DVR and the Minis. I suspect the reason the moca 2 modems worked is an issue with the GoCoax adapters -

You should talk with GoCoax directly about what you are seeing.

Title: MoCa 3.0 at 10Gb/s projected for 2022/2023

Albeit a few months old now, I thought this article might be of interest to those who are wondering what's next for MoCa.

What's next for MoCA? | Light Reading
Multimedia over Coax Alliance has a new man in charge as org seeks commitments for a new 10-Gig-capable MoCA 3.0 spec and fights for relevancy as Wi-Fi starts to encroach on pieces of MoCA's turf.
www.lightreading.com

I would agree with the premise that multi-gig and 10-base Gig over coax will remain a relevant backbone option, abject of being able to run copper twisted pair or fiber.

What do you guys think?

[Assistant]
My thoughts. This is short-term excitement if it takes off in any meaningful way.

Why short-term? Because coax is not installed in any new buildings from what I have seen. For those that do have it, it is a boon of course. But those older buildings and homes will eventually be sold and fully updated and renovated sooner rather than later.

If I had a home that was MoCa compliant (and I do) but had the choice for faster, more secure, and more consistent tech, I would choose it first (and I have).

This may not be a popular view, but MoCa, like PLA's, is the last thing to consider when true networking standards and all that entails is considered.

Of course, Cable companies aren't going to give up that built-in market easily either. So lingering local pools of MoCa users and supporters may last for a decade or more.

You're probably correct, and my thinking was more on the level of a backup option for those premises where in-wall category copper or fiber haven't yet been fitted, or cannot be for whatever reason. Certainly always better to use the real deal wherever/whenever possible. This could provide a usable-enough stop-gap, though.

@Trip, you're too kind. I'm probably going to be proved wrong, but thanks for the gentle response.

Title: Commscope amp entry splitter MoCA network- will this be my controller node or do i need a node off my router ?

I have xfinity , internet and cable with 4 drops at NON-MoCA amp splitter want to change to MoCA amplified splitter, 3 drops go directly to 3 rooms ( no splitters) for TV # 4 exits VOIP and goes to my modem/router leased Equipment > to work from home computer , I want to buy the MoCA amplified splitter & 7250's adapters as well as my own modem & router but I need guidance, please - I will install a 2-way splitter @POE #1 side to modem for computer and # 2 side to amplified Commscope ? Or can I pass #1 from the VOIP outlet as it is now ? I believed that they needed split by the 2-way as I've been searching - but I want to do this right - I will continue on once I get initial entry splitter design configuration, thanx dsc

[Assistant]
A “designed for MoCA” amplifier can be a one-to-one replacement for a non-MoCA amp. Most such amps are designed to facilitate MoCA communication between all output ports, including between the amplified outputs and passive “VoIP” output port, and have a built-in MoCA filter to block MoCA communication via the input port. (Re: this latter point, check the specs for the amp; if the spec’d attenuation is below 50 dB, consider adding a MoCA filter on the input port, to prevent MoCA signal leakage onto the provider.)

A few “designed for MoCA” 5-output (4+1) amps:
Antronix MVRA502B
PPC PPC-5M-U/U
CommScope CSMAPDU5VPI

If there’s just a single coax line to the modem+router location, that line will need to carry both DOCSIS (cable Internet) and MoCA signals, so you’d need to have the modem on the downstream side of the amp, via the passive “VoIP” port or one of the amplified outputs, owing to the built-in MoCA filter in a “designed for MoCA” amp.

Were there dual coax lines between the junction and modem+router location, you’d benefit by using the 2-way splitter as described in the OP, to isolate the ISP/modem feed from the MoCA coax segment, adding a 70 dB MoCA filter on the amp input port to ensure MoCA isolation, future-proofing the setup for DOCSIS 3.1+. (Barring dual coax lines to the modem location, ISP/modem isolation is also possible if an adjacent room’s coax path can be used for the main MoCA/Ethernet bridge.)

Thank you, that is very helpful, I know a little but it is my 1st attempt at MoCA, comcast installed the amp and that fixed bad signals yrs ago, I was just trying to do this adjustment w/o running from scratch if possible - obviously - which would be my normal way but my other half is working from home, so I'll need to keep her online ! I've had a second coax entering the same room as the modem for the TV stb - always easier for me to keep organized, Very Much Appreciated, I can start ordering supplies and will update progress

dsc150 said:

If that’s a second line between the junction and modem+router location, your plan to use an initial 2-way split for the modem is the way to go … but, as mentioned, check the new amp’s specs and add a MoCA filter on the new amp’s input port to get MoCA attenuation above 70 dB.

edit: p.s. You’ll want to use MoCA-optimized 2-way splitters in rooms where you’ll have both an X1 STB and MoCA adapter.

Title: New Fiber Install MoCA Routing Question

Hello all,

As my current contract with Xfinity is coming up here soon I'm looking into getting Metronet Fiber installed in my house as a replacement. My only concern is getting the routing correct as I know they wont be able to run the ONT into a central location in my house very easily.

My proposed idea is to have them run the fiber line into my attic just as they did with the coax line for Xfinity, then mount the ONT up there. I would then run a patch cable from it to a MoCA adapter which would then go to my office which houses all my networking equipment. In my head I feel like this would work, but I just wanted to get a second opinion from you all just to make sure I'm not crazy.

Including a diagram of my proposal to help better explain what I'm after, as well as one showing my current setup

[Assistant]
If you ever intend to go above 1 Gbit/s symmetric service, have them run the fiber to your office or enter through an exterior wall and mount the ONT inside. Don't go via moca as not likely to see much above the current 2.5 Gbit/sec half duplex ( roughly 1 Gb/sec each way for an isolated pair, lower for 3+ nodes) . Depending on which part of the world you are in, it can get extremely hot in attics 120-140 F during the summer. Not good for man nor beast or networking gear.

degrub said:

Yes, that would not work in Texas as the attics are way too hot in the summer.

FWIW - most utls going into the home - there's the demarc between community and home - and that is generally where CableTV, POTS, and Electric services hit the edge of the house...

From there - there's generally the "home run" from the demarc to the Modem/Residential Gateway...

Talk to your installer, and don't make it complicated - you should be fine if you keep it simple...

Title: Frontier internet and Moca

I recently got Frontier fiber internet installed. The tech installed a FCA252 (set to 25GW), and connected it to my Deco
X75 Pro mesh system. I don't have cable TV any more, so I want to set up a wired internet utilizing a Moca connection.
I looked inside the ONT box, and there is not another Moca adapter in it. There is a light on the unit that's labeled Moca,
so I'm assuming it's built in. I bought 4 FCA252 adapters and hooked them up. I used a 2 way splitter and ran one to my X75,
and set the switch to LAN. I installed the others at 3 other locations. All the lights are on except the Moca light on the FCA252
that's connected to the X75. I have no wired connection at this point. I have a POE filter, but haven't installed it yet. Any ideas
on what I've done wrong?

[Assistant]
kps246 said:

Quick guess … this would indicate that there is a direct coax connection between the ONT and router location, but that the rest of your coax locations are interconnected via a splitter isolated from the ONT/router connection. (Or possibly a misplaced MoCA filter.)

The ONT coax needs to feed the input port of your distribution splitter, with the router location’s coax added as an output — replacing or supplementing the splitter, as needed. A MoCA filter would offer some performance benefit installed on the input port of the first splitter encountered by the ONT coax line.

Example diagram:

(Of course, the add’l FCA252[25GW] adapter at the ONT would be skipped if your ONT supports the custom MoCA WAN frequency natively.)

edit: p.s. I’m assuming all the FCA252 adapters used for the MoCA LAN have been set to their “LAN” configuration setting.

There's an access panel in my garage I'll have to get into. I do remember him unhooking something in there. I'll have to move a bunch of stuff to get to it. I'll do that tomorrow and get back to you. I'll take some pictures also.

Here's the pictures from my access box. The original setup was a 2 way splitter
into the 4 way splitter. Looks to me like he has bypassed my whole coax system and just connected to 1 coax which goes to the office where the router is, which is right behind the panel. I also see the splitters aren't Moca compatible. Do I just need to replace the splitters and then unhook the ones he has barreled together and reconnect them to the 2 way splitter?

Title: Help with MoCA Adapter Losing Internet Connection on Frontier FIOS

Hi Everyone,

Could really use help here- I have been on calls with Frontier multiple times and they can't figure it out! I have Frontier 500/500 and am using a MoCA 2.0 adapter (ScreenBeam ECB6250) to backhaul upstairs to a Wifi access point there. It's all been working great for over a year, but all of a sudden and for no apparent reason, the ECB6250 has been losing internet connection a few times a week:
When the ECB6250 internet goes out, all lights stay green (incl. Coax light), but no internet comes through (all devices show strong signal, but no internet)
When this happens, the main Arris router continues to operate perfectly fine and I can continue to get internet from that point
I even swapped the out with a different ECB6250 I bought from Amazon, but issue persisted even with the brand new one
Issue happens even when I plug laptop directly into ECB6250 via ethernet, so I know the TP Link is not the problem
If I power cycle the ECB6250 it will work for a day or so, and then go out again in a few days or hours (not consistent)
I've restarted / power cycled everything in this diagram at least once
I don't have TV service of any kind; I use YouTube TV
Frontier can't figure it out...basically they just tell me to upgrade to their Eero mesh wifi, but I'm sure it's a solvable problem (and I'd like to keep the MoCA backhaul)
Any thoughts? Thank you!

[Assistant]
Did you use a different ethernet cable when you plugged in the laptop or did you use the existing cable going to the TP-Link ?

Best i can tell, there is no "internet" light on the modem. Are you referring to the ethernet port link speed and link activity lights on the port ?

If the light on the left side of the ethernet port turns off, then there is an issue 1) that port, 2) cable/terminations, 3) ethernet port on the other device, or 4) corrupted firmware/driver either in the modem or client device. i would swap out the cable first with a known good, working cable. When you swapped the ECB6250 with a different one and the issue persisted, that should rule out the ECB port unless there is a common firmware issue (unlikely). If the laptop lan port is working with other devices - router, switch, etc, then it is not likely the issue. That leaves the cable.
If the cable is not an issue, then add a dumb gigabit switch in between the ECB and other devices. Sometimes that cures issues.

Thanks for the response @degrub! When this started happening I tried a new cable, but still had the same issue. And I'm certain it isn't the laptop LAN port- it works with other devices.

As for lights, when the issue happens the Power and Coax lights are both green on the ECB6250. So it seems that the MoCA connection is still working, just no internet. I didn’t check the Ethernet port lights on the ECB when this happens, but I will do so next time the issue comes up (sometimes goes a day or two without problems). I do know that when it happens, the green Internet light on the TP Link access point goes out.

Appreciate the idea on the Gig switch- so you have any specific model recommendations?

i routinely use Netgear unmanaged switches. GS305 V3 is current model.

One thing to try also, would be to swap the port on the first splitter of the coax going to the 6250 with the port used for the coax going to the next splitter to the modem. Just swap the position of the cables.
