Title: MOCA issues with Xfinity

I added some MOCA 2.5 adaptors (Screenbeam ECB 7250s) to my home network a couple months ago. I'm on xfinity, using the xfinity XB8 gateway, and typically get about 1.4+ gbps down and ~250mbps. I noticed that my speedtests from all of my machines hooked up via my MOCA adaptors was usually in the 600-700mbps range, despite all of these devices using gigabit adaptors, so last week I started down the rabbit hole to fix this. A separate issue was that my MOCA connected devices would occasionally drop packets for a few seconds (I used ping -t to several hosts to test this). This wasn't enough to cause me any real issues, but my son thought this was a catastrophic problem while playing online games . I found and fixed a few things, and while speedtest speeds are a bit better on my MOCA devices, they still aren't what I'd expect - and I've also run into a few other interesting gotchas so I was hoping someone could chime in.

Issue 1: My house has a cable connection closet where everything is routed to, and it used a 5-1000mhz coax splitter. After reading some posts here, I replaced the splitter with an Amphenol 5-1675mhz splitter. Interestingly, this didn't seem to make a difference in my speedtests, though it did seem to fix the issue of packets being dropped.

Issue 2: Since my XB8 gateway supports MOCA, on my original configuration I simply enabled MOCA on the gateway and plugged in MOCA adaptors in my office, bonus room, kid's office. Everything was functional, though it was a bit slower than I had expected. While reading some posts here, I found that the XB8 only supports MOCA2, not 2.5. When I looked at the Phy rates in the XB8 web UI, the connection between the XB8 MOCA node and each of my Screenbeams was around 1500, while the connection between every Screenbeam and the other Screenbeams was around 3500. I figured the XB8 was just the weakest link in the chain so I added another Screenbeam and connected it to the 2.5gbps lan port on the XB8 - and everything stopped working on all of my devices connected via the Screenbeams. I eventually fixed this by disabling MOCA on the XB8 - more on this later. At this point, things were working again, and my speedtests improved to the 800-850mbps range. So, definite improvement - but I was still irked that I couldn't get the 900-950mbit I had expected. Here's the Phy rates I'm now seeing (all 4 nodes are Screenbeams, as MOCA on my XB8 is now disabled).

Issue 3: When I had MOCA enabled on my xfinity XB8, I liked having the ability to check the MOCA speeds in the XB8 UI. Unfortunately, once I hooked up the extra Screenbeam to the 2.5 gbps lan port on the XB8, *everything* stopped working until I disabled MOCA on the XB8. I actually had to plug a machine directly into a lan port on the XB8 to be able to disable MOCA this because nothing, including wifi, was working. Everything was working great for about 2 days until 8am today when everything, including wifi, stopped working again. I checked the XB8 web UI and MOCA was enabled again - I have no idea how this happened - maybe xfinity pushed a change to my gateway? In any cased disabling MOCA on the gateway again fixed everything. Fingers crossed this doesn't happen again... Is having MOCA enabled on my XB8 creating an invalid network state (a loop of some sort, maybe)?

Issue 4: This one is minor, but I'm curious if anyone has input. Since I can't use the XB8 web UI to see/manage MOCA any more, I decided to update the IP settings on my Screenbeams so I could access their management UI from my network w/o having to jump through hoops. I assigned each a static IP outside the DCHP scope from my XB8 and everything seems to function normally, but the devices are no longer visible in the xfinity app nor on the gateway web ui (I now have a huge page of "Offine Devices" listed in the gateway web UI's Connected Devices list, despite these devices all being online). Most of these devices have their connection type listed as MOCA, so I'm guessing that maybe it's just confused since these devices should be showing up with a connection type of "Ethernet"? I'm hoping this eventually self-corrects, but if anyone has feedback on this, I'd appreciate it. I really like to be able to see/manage all of the devices on my network, and as it is I can't.

Make sure your using a MOCA filter or all your neighbors will be connected to your network.

Unusual high data usage and unidentified devices connected to your network?
What you need is a MoCA filter between your coax cable and your router/gateway!!!!!!!
This MoCA problem exists especially in multi-home buildings where all subscribers are hooked on to the same connection. Xfinity gateways are MoCA enabled this sends a signal into the coax lines letting ALL devices talk to each other. So your neighbor unknowingly taps into your data!

I had this problem where my usual 200gb usage suddenly spiked to over 1gb and I had devices connected to my network which were not mine. When I logged into my gateway’s admin, I suddenly was in someone else’s router and I could see all their settings.

After some research on the internet, I came across the MoCA issue with Xfinity and I aquired an MoCA filter, installed it, reset my gateway and it immediately solved all my issues!!!!

Xfinity should know about this issue and give each subscriber a filter with their modem. Denying this issue and just telling subscribers to change their passwords or sign up for faster service is not the solution!!!!!

There is a filter on the coax line coming into the house, so I think I'm covered there.

Assume that it will. Install a 70 dB MoCA filter directly on the XB8 to block any MoCA signals to/from the XB8.

Others have similarly reported difficulty keeping the Xfinity gateway MoCA LAN bridge disabled. The MoCA filter will isolate the gateway from your MoCA setup, regardless of the state of its built-in MoCA bridge.

Yes, exactly that — once you complete both connections for the standalone adapter at the gateway.

Title: Are newer power line adapters worth trying?

MY sister-in-law has one room in her house that only gets 80 megabit on 5 GHz WIFI AC and even less on 2.4 GHz.
Several years ago we tried a pair of Trendnet TPL_421E2K/A AV2 1200 adapters. The were even slower than WIFI and less stable.
Is it worth trying a pair of AV2 2000 adapter?. Any brand better than another?

[Assistant]
They are not worth trying at all, ime. Not even worth the gas/wait time, to buy and return them.

It's not just how slow they are. It's how much the 'performance' varies even during a single file transfer that makes these annoying to use for me (or even recommend them to anyone).

jea101 said:

What your sister-in-law can't do with 80Mbps connection? What's the issue you are trying to fix?

The AC700-1200 Powerline adapters work great for me with 100 ft run. They work better if they are on the same circuit.

Title: Newbie MoCA questions

Hi all,

A little background:
I've been working with Ethernet for ~30 years, but I'm a newbie with MoCA, so please forgive me if my questions (below) are naïve.

I'm on Xfinity cable, which enters (and splits) in the basement in a closet at one end of the house. The closet is shrouded by a metal beam, so there are WiFi access points connected to a wired business/workgroup router and cable modem in the closet.

The house is an open plan with no good location for a central WiFi router, so there are two SOHO WiFi routers configured as access points, one at each end of the house, which also serve wired clients.

I was using Powerline plugs to connect the "other end" AP to the router - but when one of the plugs died, I decided to try MoCA because there was existing coax available. So I got a pair of ScreenBeam ECB6250 (bonded 1Gbps) to experiment with.

My setup:

The results have been mixed: the MoCA bridge is more stable and faster than the Powerline, but testing with iPerf shows that a single TCP connection can achieve only 100..120 Mbps. I can get up to ~930 Mbps between wired clients across the MoCA bridge, but only in aggregate by using multiple TCP connections.

After the first few connections, the bandwidth of individual connections drops off slowly, but aggregate bandwidth keeps rising until the bridge is saturated with 15..18 simultaneous connections.

This is in contrast to Ethernet where a single TCP connection can use all the bandwidth.

Is this to be expected? I know MoCA creates multiple frequency channels, but I would have thought that the controller would spread Ethernet traffic across the channels to try to use all the bandwidth. Or is it just the case that the particular equipment I have doesn't do this?

Thanks,
George

This is common with iPerf testing of MoCA; 4+ parallel streams are required when using iPerf. Maybe @gocoax can shed some light on why.

Given your cabling and device locations, it would be preferable to split the cable modem signal off prior to the amplifier using a 2-way splitter, then installing a 70 dB “PoE” MoCA filter on the input port of the amplifier (as you currently have) to isolate the ISP/modem feed from your MoCA-infused coax. Also, you might get better MoCA performance/efficiency using a “designed for MoCA” amp, like the equivalent PPC model# PPC-5M-U/U.

This won’t alter the iPerf behavior but it might improve the MoCA PHY rates or power usage; and it will prepare your setup for DOCSIS 3.1. Related to:
DOCSIS encroachment on the MoCA [Band D] frequency range

krkaufman said:

If I understand correctly, you are saying that MoCA will limit a single TCP connection to the bandwidth of a single coax channel and *not* try to spread over all available channels.

That's a little disappointing.

Internet-only or do you also subscribe to cable TV, or might you?

The X1 boxes are TV (not game consoles).

I can try isolating the modem, but I'm not sure what that really accomplishes. The modem is *not* MoCA and should ignore it completely.

WRT the amplifier: the X1 boxes are MoCA and they seem to have to talk to one another to work. Xfinity called one of them the "master" and the others "slaves". Also, Xfinity installed that amplifier, so I figured it was ok.

The modem is DOCSIS 3.1. Don't know about the X1 boxes or the underlying service.

krkaufman said:

On one of the wired clients of the MoCA bridge I have two separate instances of Ookla Speedtest which can be run simultaneously. This is the desktop app (not in browser) and it uses just one TCP connection to the test server.

Running either Speedtest singly, I get 110..120 Mbps. Running both simultaneously, I get 110..120 Mbps from both.

So it's not just an iPerf artifact ... it seems to be a real situation.

Title: What moca adapters can be manually configured for frontier LAN settings (1025-1350/mhz) ?

Hello, have frontier internet with Arris gateway and moca FCA 251 adapters. 1 at don't and another at gateway. I have a moca splitter and need to find a moca apdter that works in the LAN range of 1025-1350mhz (c4-D4 channel ranges) the gateway also works as a man moca adapter

I bought SCREEN BEAM (Ecb6200) 2.0 moca bonded adapter but the download was ranging from 50kbps to 100mbps downloads and at times stop working all together. Customer service told me in could access device and gave me the I.p. address, but it did not work. I tried to call customer service back but after 25 attempts in gave up and returned items to amazon.

Questions:
1- I am looking for FCA 251 adapters on amazon in case that may be a solution. Would the fca252 be compatible with fca251? I need them in LAN to not conflict with WAN setting between ONT and gateway moca adapters already installed and configured to WAN.

2- Is their a moca adapter the can be manually configured in the device settings to look for 1025-1350 mhz (C4-D4) channels?

Thank you for any help you can provide.

[Assistant]
First question ... Do you also have TV signals on the coax? Or is your coax currently only used for the MoCA WAN link between the ONT and router, with the planned addition of MoCA LAN connectivity?

For reference...

FCA251/WF-803FT (GigE port):
WAN: 1475-1675 MHz (2x 100 MHz; 1000 Mbps max)
LAN: 1025-1350 MHz (3x 100 MHz; 1500 Mbps max)
FULL: 1125-1675 MHz (5x 100 MHz; 2500 Mbps max)
FCA252 (2.5 GbE port):
1GW: 1475-1675 MHz (2x 100 MHz; 1000 Mbps max)
25GW: 400-900 MHz (5x 100 MHz; 2500 Mbps max)
LAN: 1125-1675 MHz (5x 100 MHz; 2500 Mbps max)
Summarizing...

FCA251[WAN] == FCA252[1GW]
FCA251[FULL] == FCA252[LAN]
FCA251[LAN] ... unique
FCA252[25GW] ... unique
The preferable solution, if you do NOT have TV signals on the coax, would be to switch to using a pair of Frontier FCA252 adapters, set to their "25GW" configuration, for the MoCA WAN link, leaving the whole of the standard MoCA Extended Band D frequency range available for MoCA LAN use -- and enabling full throughput MoCA 2.5 networks for both the WAN and LAN. (example diagram)

Hi, no tv signal. Only have internet service with frontier. Currently uses moca FCA 251 as WAN on router and at ont locations

Title: New MoCA network

I’m helping out a friend extend their Internet signal to their 2nd floor.

The house is a 2 story house with a basement. The Spectrum coax Internet comes from the pole into the basement, the spectrum technician drilled a hole underneath the 1st floor office and brought the cable into the 1st floor office, it is then connected to an antronix power amplifier which then connects to the Spectrum Modem. The basement ceiling has a lot of coax cables going to various rooms in the first floor and 2nd floor. Some of those cables are connected to two way splitters which eventually are connected to the box on the outside of the house.

What are my options to get a functioning MoCA network? Should I remove the Spectrum Internet coax cable from the power amp, connect it to a 2-way MoCA splitter, one end going to a MoCA node and the other end going into the power amp that connects to the modem? I would then feed an Ethernet cable from the router to the MoCA node. Where should I place the PoE filter?

[Assistant]
An isolated run of coax from the area of the router to the area of the 2nd floor would be ideal. If you can get that, moca 2.5 modem on each end, ethernet port on first modem connected to router, second connected to user device (or switch, AP, etc)

If you cannot do that, then need to sketch out a map of all the coax "from - to", ALL of the splitter model #s, names and a picture, and devices attached. Start at the demarcation box outside.
This will matter depending on the route for moca as there is a limited power budget available in the moca amp.

For the ISP modem/router, is it running DOCCIS 3 or 3.1 ? This can make a big difference in the approach/equipment as 3.1 typically uses some of the MOCA 2 or 2.5 frequency bands. If currently on 3, the ISP is likely planning for 3.1 sometime in the near future, so planning based on that is advised.

Any splitter, powered or not, in the MOCA path needs to be replaced with a MOCA 2 certified splitter.

If the TV set boxes are using moca already, it can be difficult, but not impossible to implement moca 2 over that.

IF the user can switch to fiber to the house for an ISP, then that might solve some issues if the internal cable plant is no longer used by an ISP.

krkaufman said:
Heh, those pics look familiar!

You all set?
Not yet. I plan on going back this weekend and if I run into any issues I will sketch out a map but it seems pretty straight forward.

krkaufman said:
Heh, those pics look familiar!

You all set?
Here’s a hand drawn diagram of the topology. I have three unused cables which are next to the 3 way splitter that the ISP coax cables are connected to. I don’t care too much about having the 1st floor bedroom connected but would like the 2nd floor living room part of the MoCA network. The cable that’s currently unknown
, I have to figure out where it is.. if it goes to the detached garage then yes I would like to use it.

Title: Preparing to buy a set of MoCA 2.5 adapters...

I'm about to order a set of ScreenBeam MoCA 2.5 adapters ECB7250:

Amazon.com: ScreenBeam Bonded MoCA 2.5 Network Adapter for Highest Speed Internet, Ethernet Over Coax - Starter Kit (Model: ECB7250K02)

ScreenBeam appears to be a retail outlet for Actiontec(?), so I'm assuming these adapters are nearly the same/good as Actiontex ECB7250s sold to ISPs, etc. (not available in the retail channel). 'Good as' including Actiontec-sourced firmware and documentation. These adapters (Actiontec) appear to use the latest MaxLinear MxL93712 chipset.

Application will be over coax dedicated to MoCA and two OTA TV antennas (coupled and preamped; no cable modem/DOCSIS signaling). I plan to add two POE/LPF/MoCA filters, one at each end to stop the MoCA signal from reaching the preamp/coupler/antennas and the TV/AVR tuners.

A few concerns:

o Any feedback on the ScreenBeam adapter choice?

o Any suggestions for sourcing the MoCA filters? The goCoax filters look good: OT-LPF-1002 | goCoax

o Can I inject the antenna preamp power at the media center end of the MoCA run (like I'm doing now), or should I place it beyond the MoCA filter at the antenna end, just below the preamp?

o I assume I can use a non-MoCA splitter beyond the MoCA filter at the media center end(?)

Thanks for any advice!

OE

[Assistant]
DC power injector for the TV pre-amp will see some additional line loss going through two splitters, assuming they will pass DC ( i assume so) . My injector is directly off the coax from the pre-amp to minimize voltage drop before the TV signal passes to the MOCA modem AUX/TV coax connection.

which legs of the splitter are connected to what on each end ?
Looks like an additional 7-8 dB of insertion loss for the TV signal with two splitters in line.

I may move the preamp power to the preamp end since I am adding some splitter attenuation.

Yep.

Splitter inputs are from the TV antennas.

you might have to be careful in the TV signal path with the orientation of the splitter, if i am remembering my rf correctly, as the spec indicated substantual return loss in the 5-1000 MHz range. But i may be misremembering these days.

Check the specs on the DC injector. It may already have significant filtering on the reverse path to the antenna.

Title: "I thought it would be easier..." a.k.a. Newbie needs help setting up MoCA 2.5 (scream beam) + FiOS 1gb using existing Coax

I hate to be Captain Obvious but I have no clue how to utilize the scream beam MoCA 2.5 adapters using our existing COAX.

My goal was to have a MoCA adapter in 4 different rooms to improve performance.

I've attached images of existing and what I thought would be future state.

** Thank you in advance for the support **

Questions:
I don't have connectivity - internet access - from any of the MoCa 2.5 i added.
Existing setup works just fine as before. No internet access from MoCA 2.5 adapters.

Where should I locate MoCA units? One before the splitter and then one MoCa at end of each run I have identified for MoCA?

Currently:
Frontier FiOS
No TV, No STB's, no "modems" just straight 1gb FiOS service - no issues, internet access better than good

1/ FiOS 1gb serviceman to house (ONT).
2/ ONT to attic location via Coax.
3/ In Attic FiOS installed powered splitter. not branded as Frontier nor verizon.
4/ Two runs are attached to splitter. One run has nothing at other end just standard term/connector. Second run goes to family room, has FiOS Coax to ethernet powered adapter
5/ From adapter to Netgear Night hawk ac2200 router using ethernet cable
6/ Router to DirecTv box via ethernet
7/ AC2200 blasts wifi and well it works ok until you walk away

[Assistant]
DragonsSouthlake said:
3/ In Attic FiOS installed powered splitter. not branded as Frontier nor verizon.
Are you sure it’s powered? A powered amplifier makes zero sense for your setup, given you have no TV STBs. Can you provide the brand & model # of this splitter?

DragonsSouthlake said:
Second run goes to family room, has FiOS Coax to ethernet powered adapter
What is the brand & model # of this adapter? If there is a physical configuration switch next to its coax port, to what position is it set?

Making assumptions, hopefully what you have is a Frontier FCA252 adapter set to “25GW” connected to the Ethernet WAN port of your router, allowing use of the ScreenBeam adapters to extend the router LAN over your coax. The critical bit is that the FCA252[25GW] setting shifts the FCA252 adapter’s operating range to 400-900 MHz, compatible with the ONT’s MoCA 2.5 WAN configuration — leaving the full MoCA Extended Band D range (1125-1675 MHz) available for LAN use.

‘gist: You'll be operating two separate MoCA networks over your coax, one for the WAN link, and the other to extend the router LAN around the house.

To get the MoCA LAN running, you’d need to install one ScreenBeam adapter at the router, linked to a LAN port on the router, and using a MoCA-compatible 2-way splitter to allow both the ScreenBeam “LAN” MoCA adapter and FCA252 “WAN” MoCA adapter to be connected to the room’s lone coax outlet. And you’d then install your other ScreenBeam adapters in each remote room targeted.

However… you’ll likely also need to replace the attic device with a right-sized MoCA-optimized passive splitter (example), with a MoCA filter (example) installed on its input port.

Example:

Thank you,
Pictures attached

1/ Prior to going with just FiOS internet, we did have Verizon at one point with 3 STB's. Not sure if power splitter was installed by Verizon or a few years later by Frontier.

Splitter is CCC brand, has power using coax cable from a/c outlet to splitter, coat into splitter is from not box; out of splitter to a 8 port "not" powered splitter

2/ The FiOS adapter is a FCA252, InterTek 3173364, branded as Frontier FiOS, has 1GW LAN 25GW label on coax side of unit

3/ Coming out of FiOS FCA252 is an ethernet cable connected to Netgear WAN port

Ok, so that all maps to my assumptions in the prior reply, so you should be able to follow those details to get your setup working. Ask questions, as needed.

Title: MoCa: Complete newbie setup help

Hello,

Completely new to Moca (and networking in general). Purchased a Screenbeam 2 adapter kit. Xfinity Internet with Modem/router combo. I did enable Moca capability on the router.

I have coax cables running through the house and have identified the main in line and the line to the room I want the Moca connection to. Currently I have main coax in to a Moca 2.5 splitter. One splitter out directly two the modem/router coax connection. The other splitter out directly connected to the coax line that runs to the room. At the room, I have the coax out connected to a screenbeam Moca adapter, ethernet from adapter to my Xbox one. I'm getting internet through it, and the Xbox can connect over the Moca network, however, my NAT type is always strict not allowing to connect to online games. I have tried a bunch of stuff to fix the nat type via the router and xbox itself when on Moca connection to no avail (opening ports, assigning the xbox reserved IP, etc.). I don't have the NAT problem over wifi but signal strength an speed sucks over wifi which is why I'm interested in MoCa setup. Wondering if it's in how my Moca network is set up.. Does it sound like this current setup should work?

Or do I need another adapter at the router? The screenbeam setup says to do the following. Ex: Main line coax in to splitter, splitter port one direct to router, splitter port two to moca adapter, moca adapter ethernet port to router ethernet port.. Then the room setup the same as I have it. But I guess I'm confused, as if I follow that, I wouldn't have any connection to the coax that is running direct to my room where my other moca adapter is..

As I said, I'm not well versed in any of this, so I might just be a lost cause lol. Thank you for your assistance in advance!

Two reasons you might want to do so:
If it somehow fixes the odd "NAT" issue with the Xbox connection.
If you want the best possible throughput over the MoCA link, and the pair of adapters purchased are MoCA 2.5. (The XB gateway built-in MoCA LAN bridge is bonded MoCA 2.0, at best.)

Were you to want to use a standalone MoCA adapter as your main MoCA/Ethernet bridge, replacing the gateway built-in, you'd want to:
disable the gateway's built-in MoCA LAN bridge;
add a 70 dB MoCA filter directly on the gateway coax port, as insurance against the gateway interfering with your MoCA network were the gateway built-in bridge to somehow become re-enabled;
use a MoCA-compatible 2-way splitter at the gateway to get both the gateway and the additional MoCA adapter connected to the coax, in parallel.
link the added MoCA adapter, per your comment, to a LAN port on the gateway, to effect the MoCA/Ethernet bridge.

p.s. The OP doesn't mention the required "PoE" MoCA filter. You'll want to make sure that you have a 70 dB MoCA filter installed on the input port of the initial 2-way splitter (or upstream) to make sure that MoCA communication is blocked at the cable signal point-of-entry.

Awesome, thank you! I have purchased the filters and will try the setup as recommended when they arrive. Appreciate your guidance.

JMHamilton88 said:
I have purchased the filters
Getting a 70+ dB filter model is important, since MoCA gear can push through a typical 40+ dB model.

Title: Moca in UK advice needed - novice!!!!

Hi

Really looking for some advice. I am moving house soon and I have been told there are arial sockets in all the bedrooms (one of which will be an office) plus 2 in the lounge fed from an amplifier in the loft.

I was initially planning on trying to use Homeplug type adapters to give me networking through the house but have never found them to be hugely reliable but okay for some limited use.

I have stumbled across Moca which appears to be very similar to our arial cables except they have different connecters.

I really don't need arial sockets as almost everything we watch is streamed or SkyQ, so networking is far more important than arial for TV.

I also plan on using this as a backhaul for my Synology Routers one on each of the two floors for meshed WIFI

Questions.

Do I have to change all the connectors or will simple plugin converters do the job, is there ea simple step by step guide (for UK users) to getting this all set up and working.

Is there anything I really must look out for???

Any and all help advice will be hugely appreciated.

See this thread here: https://www.snbforums.com/threads/moca-in-uk.81455/post-855379

The OP of that thread never posted a follow up so I don't know whether anything came of it.

Thanks, I did see this thread before I posted my own question, as I did not see any follow up from them and a lot of suggested items where from Amazon USA and not sure if they are appropriate to UK.

Also I am not sure if I can simply use an adapter to change a UK arial connection to the Moca type connection or if this would significantly impact performance.

Also , looking at some of the distribution blocks, if I am not connecting an arial, does anything actually go in the input, or do I just connect all the cables in my loft to the outputs and leave the input empty?

Robin

if you need to go from one aerial segment to another segment then you would need to remove and connect the two coax cables with a barrel union or replace the amp/splitter with a moca 2 certified splitter.

if my understanding is correct, aerial connections were for satellite receiver based tv ? If so, the coax cable should be the equivalent to US RG-6 coax. This is perfect for moca.

the wall plate connection is probably best addressed by obtaining a coax cable suitable for aerial usage and cutting off one end, re-terminating with a US style coax connector for RG-6 which will match up with the moca modem connection. You will need to invest in a quality termination crimp tool and connectors. Check the cable outer cover, shield, and inner insulator outer diameters versus the US RG6

you will need to do the same if you need to buy a new moca splitter to replace the satellite splitter/amp in the attic. However, i would test with a pair of moca 2.5 modems to see if you have to. satellite frequencies in the US are higher than moca, so it may not work. Check the frequencies used for the UK satellite tv services. Moca operates between 1125 and 1675 MHz. US satellite ( direct tv) operates at 2.x GHz area.

Title: Will MoCA Work?

Old house built in the early 1920s, we’re trying to easily get an Ethernet line to several rooms and the carriage house that’s about 60ft from the main house.
A few years ago Spectrum ran coax cables to several rooms as well as the carriage house. Can any one point me in the direction of a MoCA compatible amplifier/splitter that can make this work? In the past I've used this Holland 8-way splitter but I think I will need something else here.

If you can disconnect a couple cables and make a dedicated run, that will be your best bet. Just toss whatever MOCA adapter you want on both ends and you have essentially an ethernet run (but with about 3-4msec of latency). If not possible you'll need MOCA rated splitters (easy to find online) and probably filters too.

An 8 way splitter will destroy your signal. If you need that many drops, start with one splitter that feeds your MOCA endpoints, cable modem, and a port going to an amplifier/splitter to feed TVs as they are much less sensitive to amplifiers and the issues they can introduce.

Cable TV is currently being used at all coax ends.

rpmartinez1987 said:

Well MOCA is going to be difficult but probably doable. The 2 tier splitter/amp setup still applies, MOCA and modem (plus the TVs that share those runs) on the smallest splitter you can use, then an amp and splitter off that for the rest of the TVs.

I'm assuming running an Ethernet or another coax is out of the question? Depending how it was run, may be able to use the existing wire to pull through 2 new ones.

Another thought is a 2 way MOCA splitter off your main splitter, with filter, which would theoretically let the MOCA talk directly, and still let the amplified TV signal reach those TVs.

Maybe if you make a simple diagram of the coax runs, MOCA locations etc it would be easier to figure out the best setup.

Title: Frontier FCA 252 Limited in bands?

So after much troubleshooting, and many hours later, I believe I have found to be what the cause of my issues with the FCA252 adapters I had ordered from eBay. I came to the conclusion of these adapters being busted, and had ordered a pair of gocoax moca 2.5 which just came in yesterday, and they had solved my problem, so this eliminated all possibilities of my network, or a router setting, or the devices I were using. Well, I had noticed in the web configurator for the FCA 252 it only shows me D-EXT bands, but the gocoax show me 3, D-Ext, D-High, and D-low. Switching the gocoax to only have d-high brings back the issues I was having initially with my fca252's. I do plan on returning these FCA252's, as for my use case these are a paper weight, and I'm curious if anybody else's web portal looks like this.

And I'm not expert in MoCa, I'm only just learning so please forgive me. I'm not entirely sure if these 3 bands are necessary for MoCa 2.5.

EDIT: Just to clarify, I'm using the LAN band on the fca 252.

[Assistant]
Oh, and I do want to clarify the *issues* I was having with the FCA 252's. First one was an insanely high latency on my Xbox, doing the built-in speed test I was getting almost 120ms ping higher than these GoCoaxs. Second of all, I was getting buffering streaming local movies but only on my android tv boxes, my xbox and pc worked fine on them. I stream the movies from my NAS, using SMB, and after turning off smb and going to NFS the issues went away. Something about the android tv, and SMB these FCA252 did not like. And if I did SMB streaming, over local ethernet with android tv, it worked fine, so clearly it was the adapters. And I even went as far to plug them straight into each other with a short half foot rg6 cable. Now, with the gocoax? I went back to SMB and it worked perfectly fine.

whitedragonn said:

What's your "use case"?

I'm not sure the FCA252 adapters are configurable via the web UI, at least as relates to their operating frequency; to my understanding, their operating frequency is set via the physical configuration toggle switch next to the coax port ... with the operating frequencies as follows:

FCA252 configuration toggle switch settings:
1GW: 1475-1675 MHz (2x 100 MHz; 1000 Mbps max)
LAN: 1125-1675 MHz (5x 100 MHz; 2500 Mbps max)
25GW: 400-900 MHz (5x 100 MHz; 2500 Mbps max)
WARNING: The "1GW" setting of the FCA252 (and "WAN" setting of the FCA251) appear to impose a 2-node-only limit for the associated MoCA network, only allowing a dedicated pair of adapters rather than the typical default 16 node maximum. Reports indicate that the FCA252 "25GW" setting doesn't impose the same limitation.
Just confirmed this 2-node-limit issue with the "1GW" setting a couple weeks ago. (reddit thread)

I posted in my second comment. Mainly for streaming movies from a NAS to a streaming player and light gaming. And yes there's no configuration you can do, I was just saying inside the web ui I only noticed D-EXT. Why are the other two bands not there that the gocoax has?

Title: Does Arris MEB1100 MoCA adapter have a firmware update?

I'm using an Arris MEB1100 MoCA adapter to bridge between my Frontier fiber ONT and my Google Nest wifi network. Mostly it's working great but twice since I installed it I've lost internet access for no apparent reason. Both times I was able to restore it by cycling power on the Arris device. That leads me to think that it might have a software glitch that can be resolved by a firmware upgrade. I know it is a simple device and might not even have firmware. Does anyone know? Thanks.

[Assistant]
Duplicating the reply to your reddit thread:
Presuming that the USB cable, itself, isn't damaged, what is the power source that you're using for the MEB1100? Per the MEB1100 that I have on-hand, its power requirements are "5V 900mA" ... so a 5V 1A USB power adapter should work. I'd recommend trying a few different adapters, given the issues you're seeing.

Re: firmware version ... no clue what it's actually running because I'm not aware of it having a web UI that would provide this info, nor am I aware of firmware update options. That said, the unit I have lists "1.01" as its "HW Version."

Someone else suggested trying a different power supply. Easy enough so I'll try it tomorrow. My experience with power supplies is that they either work or they don't, as long as they produce the right voltage and have enough amperage. I checked the label on the one I'm using but I have plenty of others. The USB cable is brand new. I couldn't find a male USB-A to male USB-A one in my box of many cables. The Ebay vendor claimed it was 1.01 but I have no way to verify. Thanks for the help.

PaulTopping said:

They would have read this off the label on the underside of the unit, same as I did.

Title: Another newbie, looking to see if I have setup correct

I have:
OTA antenna, with amp, coming to coax splitter, that routes signal to 2 TVs (expanding soon to 3 TVs).
Router wired to switch (plus wireless devices). The router is next to one of the TVs.

I am considering a set (2 for now)
-- Bonded 2.0 MoCA adapters (TrendNet TMO-311C2K. I'm not a gamer so am not worried about latency and 100-200 Mbps is fine).
or
-- Bonded 2.5 MoCA adapters (Hitron HTEM4)

These have 2 coax and 1 ethernet ports each. I will be adding a switch(s) to the remote MoCA adapter(s) for device connectivity.

As far as I have read, OTA and ethernet are compatible on a MoCA network.

Questions to make sure I have this correct:
1.) Beyond the two adapters, all I need is a single filter, placed between the amp and the coax splitter, correct?
2.) The adapters, which state the two coax ports are 1xMoCA and 1xTV, wouldn't need filters, correct?
3.) The signal from the antenna would be coming from the wall, split, then to the MoCA adapters, where those would add the ethernet (via MoCA), correct?
4.) All my devices are static private IPs so wiring the MoCA to the switch(vs to the router) will make no difference, correct?

I appreciate your expertise and help,

I recently added a MoCA segment shared with my OTA TV antennas. I only placed a MoCA filter at the antennas to block MoCA signaling to the antennas... did not want to broadcast anything.

The other place for a MoCA filter would be at the demarc to block MoCA signaling to the ISP/WAN connection/neighborhood... this is not required when not connecting your MoCA network to your ISP network.

Regarding the MoCA adapters... it seems that the latest 2.5Gbps adapters with 2.5Gbps Ethernet port do not include the integrated MoCA splitter (2 coax ports)... so I added my own external MoCA splitters.

FWIW, such MoCA adapters use an internal diplexer (dual filters), rather than a simple splitter, to splice the signals, to save a bit of signal strength … with the MoCA adapter RF pass-through port then having a pass-band of 5-1002 MHz (OK for passing cable and OTA signals).

In a MoCA/OTA setup, a similar benefit can be gained by using antenna/satellite diplexers … when using MoCA adapters lacking a pass-through port. (Same can’t be done for MoCA/cable, since the cable frequencies don’t align with the ant/sat diplexer pass-bands.)

mthomp said:

OTA and retail (Band D) MoCA are compatible, can coexist, on shared coax.

* OTA: 54-608 MHz
* MoCA (Ext. Band D): 1125-1675 MHz

mthomp said:

Preferably a 70 dB MoCA filter installed directly on the MoCA-optimized splitter’s input port, to prevent MoCA signals from hitting and emanating from the antenna.

mthomp said:
2.) The adapters, which state the two coax ports are 1xMoCA and 1xTV, wouldn't need filters, correct?
Correct. (A MoCA filter blocks MoCA signals, so a MoCA filter on the MoCA port would be self-defeating.)

It’s not impossible that a TV might be affected by MoCA signals, but it’s uncommon. A MoCA filter could be added on a given TV if the TV seems to be exhibiting symptoms of MoCA sensitivity.

Re: 3 & 4… correct Re: both.

Title: Another Cheap Moca 2.0 non-bonded adapter

Just saw these and never heard of them before. They are similar to the g1100 units I have that have a non-bonded moca 2.0 that I hit 500Mbps with between two units connected together. The good thing about these things is that they are CHEAP at $28 shipped:
https://www.ebay.com/itm/Arris-Fron...riorityMailPaddedFlatRateEnvelope!35613!US!-1

You can even find them for a bit less, and price seems to be coming down:
https://www.ebay.com/itm/Frontier-F...496816&hash=item5b588b9c68:g:z5MAAOSwEJZdHNm1

Why do these present a good value? Well, they're more than just a moca adapter. They're a 4 port switch, an AC access point, and I think even the usb port can be used for storage.

So you can use a pair of these to have improved wifi, more wired devices, and a moca network all at once in one device.

[Assistant]
Ok, another FiOS router that can be repurposed as a MoCA adapter+. Thanks for the heads-up.

Makes sense to consider these over the WCB3000N, except where cost is strictly the driver.

Oh for the small increase in cost, these definitely make more sense than the WCB3000N since it's 2.0 vs 1.0. Even when not bonded 2.0, speeds far exceed 1.0 speeds.

Samir said:

Entirely subjective, weighted by each individual, thus the “strictly the driver” caveat. (note: The WCB3000N is MoCA 1.1 w/ 2 GigE ports, and capable of up to 150 Mbps, for just $17. Been as low as $10.)

From what I can tell, one difference between these and other FiOS gateways is that these must not be capable of a built-in MoCA WAN connection (via MoCA Band C), as the install info seems to require a separate MEB1100 MoCA adapter for MoCA WAN installs.

Title: Add Verizon MoCA ASK-MAE340 to a network of ScreenBeam ECB7250s

Hello,

I have 5 ScreenBeam ECB7250s working at my place, and I bought a "Verizon ASK-MAE340" (https://www.verizon.com/support/residential/internet/equipment/moca-ethernet-adapter ) to add.

Couple of questions:
After I upgraded my ECB7250s from Firmware 1.17.5.0 to 1.18.7.5, the only band I see is "D-Ext". Before there were more bands I could configure. Is this going to be a problem?
The ECB7250s have both "Network Security" and "Enhanced Network Security" passcodes. How do I configure these on the ASK-MAE340?

Thanks!

[Assistant]
Selecting D ext is to drop the lower two bands to allow coexistence with DOCCIS 3.1 . Basically, you give up 40 % of your available bandwidth.

A 5 port Gbit switch would have given you the same result, maybe for less cost. The 2.5 Gbit port is a bit of marketing, since all devices in the chain have to support that link rate and there are no competitors for the wire.

Here's what I have on all Screen Beams:

Are you saying I don't need to have that selected at all? (That what was selected by default after I updated the firmware)

Is there a place you can point me to so I can read more what these parameters mean? (I just installed this MoCA setup about 1 week ago), trying to get rid of ethernet cables that I ran on all rooms (under the carpet) about 10 years ago..

My cable modem is the Motorola MB8600, which as I understand, works on the bands 5-1002 Mhz.

Any thoughts on question #2?

Thanks!

1) i am not familiar with those modems and their software. Several other folks here have used them so search for Screen Beam in this forum.
2) the moca alliance has published several guides over the years. There are links posted in the threads. Users KrKaufman and Ozarkedge will have them on their threads. Or you can search the internet.
3) that cable modem does not use bands in the moca region. No issue.
4) #2 security - no idea. Have not worked with that device. maybe there is a user guide on their website ?

Title: Troubleshooting and Diagnosing MoCA Network (ScreenBeam Devices)

Hello,

I recently installed 3 pairs of of the ScreenBeam MoCA adapters (5 adapters installed + 1 spare), configured Network Privacy, ip addresses through DHCP on the same LAN as the network I wanted to extend. They have been working fine overall l without major issues.

However, today, out of the blue, one of the adapters (the one that is connected to the network switch that provides access to most of the devices I want to connect) stopped working (The coax cable light turned off). (The other 4 adapters had both LEDs on).

First I thought, something was wrong with the coax cable this adapter was using (which I had replaced today as well). However, after getting a different cable, and power cycling the adapter, I couldn’t get it to work and connect to the other ones (coax cable light to light up).

I then started power cycling the rest of the adapters (one at a time). At first, each adapter wouldn’t join back to the Network (coax light off) after I turned it off and back on, until I power cycled one of the adapters (which happened to be the last one to power cycle), and then all of them started working right away.

This made me come up with the following questions:

- What made this happen? (I am concerned because if this happens again, everything will stop working until I manually power cycle all of them, not reliable).

- How can I prevent this from happening again?

- Is there a good wat to monitor or troubleshoot issues?

- Do these adapters have a CLI?

Thanks.

[Assistant]
1) moca modems do not need an ip address on your lan. They are transparent to your lan. Reset them to factory. Enable security if you want. A moca POE filter at the top of your moca network should work just as well.

2) do you have power blips occasionally? A ups can be beneficial.

3) there could be a failing power brick on one of the modems. More likely than a modem failing and a devil to prove.

4) are there any other devices on your coax that use moca ( DVR perhaps) or do you share the moca coax with a DOCCIS 3.1 modem ?

Thanks for the reply.

1) I can reset them, but I'd like to make their IPs part of my LAN just for convenience to access their web interfaces to check their status and performance. I do have the Moca filter installed a well (between the coax cable coming from outside and the main splitter).

2) Not really. The adapter I mentioned that was having issues, is actually protected by a UPS.

3) good point. I have a spare moca Adapter with its power supply. I might with to swap them to test.

4) Yes. The Moca Adapter that has issues is actually sharing a coaxial cable with a DOCSIS 3.1 Modem (Motorola MB8600). The coax from the wall connects to a 2-way splitter where one goes to the Moca Adapter and the other one to a DOCSIS 3.1 Modem. (not my preferred setup, but I don't seem to have another way to get this connected).

As per the document below, the cable modem operates in the 108-1002 Mhz frequencies..

https://en-us.support.motorola.com/...edirect/1/filename/MB8600-DataSheet-28317.pdf

Can that be a problem?

No, that is DOCCIS 3 territory and not a conflict..
power, overheating, would be my bet , either wall warts or the device, since they ran well for a long time.

Title: Questions on my GoCoax 2.5 Adapter Install

Hi everyone,

Sorry for the long post in advance

I've finally pulled the trigger and went ahead and installed my 3 GoCoax 2.5 adapters in my home. I have been debating back and forth about running ethernet cables from my mesh router to other areas of the house, but ended up going with the next best thing. My plan for using MocA really was to add a wired backhaul to my 2 mesh Orbi satellites to provide stable and relatively consistent Wi-Fi speeds throughout the house.

DISCLAIMER: For those that don't know, the Orbi mesh system is a triband router that uses a wireless 5Ghz backhaul to communicate with each other - I do know that even though by enabling a wired backhaul for mesh communication, I won't be able to actually use this 'freed up' bandwidth for Wi-Fi. The reasoning behind me continuing to move forward with using MocA in this case is to see if it truly made a difference in Wi-Fi output speeds from the Orbi nodes using a wired backhaul vs. wireless.

For reference, I attached a schematic of how I wired everything, based on what I've read and understood to be correct and below is some more information for context:
Home Size: 3700 sq ft
Internet Provider/Plan: Xfinity 800/20 Mbps (no TV, internet only)
Cable Modem: Netgear CM1000 (DOCSIS 3.1)
Mesh Router: Netgear Orbi RBK750 (1 Router, 2 Satellites)
Here are average speed results after MoCA install and setup, testing using my laptop and Speed Test app:
Guest bedroom satellite, connected via ethernet cable: 850-915 Mbps down / 22-23 Mbps up
5 ft away from Guest bedroom satellite, connected via Wi-Fi: 750-800 Mbps down / 22-23 Mbps up
15 ft away from Guest bedroom satellite, connected via Wi-Fi: 715-740 Mbps down / 22-23 Mbps up
Living Room satellite, connected via ethernet cable: 850-915 Mbps down / 22-23 Mbps up
5 ft away from Living Room satellite, connected via Wi-Fi: 730-760 Mbps down / 22-23 up
15 ft away from Living Room satellite, connected via Wi-Fi: 700-720 Mbps down / 22-23 up
Speeds seem higher with MoCA installed, as compared with my Orbi's defaulting to wireless backhaul. For example, I remember getting 620-650 Mbps down when I was 15 ft away from the Living Room satellite.

In summary, everything is up and working to my knowledge. No disconnects, drops, or connectivity issues. That said I do have a few questions for you all:
Knowing that I have a DOCSIS 3.1 modem and that MoCA frequencies overlap some of the range, I did originally install an extra POE MoCA filter at the coax port of the cable modem. However, I think that seemed to do more harm than good - I couldn't even log into my cable modem to see signal levels/stats with the filter on. So, I removed it and I can access my cable modem again and as I mentioned, everything is back to normal. Is this something I need to worry about?
My original setup prior to the MoCA install had no splitters whatsoever in my coax lines. Since the install I have introduced 2 splitters (indicated in the schematic), which I think have raised my cable modem upstream power levels to around 50-51 dbmV. As I mentioned, I haven't experienced any disconnects, modem restarts, or connectivity issues since the install but I know that range is close to the max accepted tolerance levels for the modem. Is there any way of reducing the upstream power, knowing that I still need to have 2 splitters? I have seen some splitters that have a lower db loss that I could potentially switch out, but I'm not even sure if that'll make a difference to the upstream power levels. (I've seen a 2-way splitter that has a -3.7 db loss vs. the -4.5 db loss I have now installed).
I haven't logged into the GoCoax web interface yet - do I even need to or is there any particular settings I need to check off to ensure my MocA adapters are fully optimized based on my current setup? It seems even trying to access the interface is troublesome.
There's a MPS (MocA Protected Setup) button on my GoCoax adapters - is this something I need to turn on or necessary? I read in the instructions that by default it is off.
Thank you so much in advance for your input!

However, I think that seemed to do more harm than good - I couldn't even log into my cable modem to see signal levels/stats with the filter on. So, I removed it and I can access my cable modem again and as I mentioned, everything is back to normal. Is this something I need to worry about?

If things are working and stable then the modem doesn’t appear to be sensitive to MoCA signals and so wouldn’t require the additional “prophylactic” MoCA filter. That said, installing a working MoCA filter on the modem shouldn’t produce the symptoms described.

unioncorps said:
2. My original setup prior to the MoCA install had no splitters whatsoever in my coax lines. Since the install I have introduced 2 splitters (indicated in the schematic), which I think have raised my cable modem upstream power levels to around 50-51 dbmV. As I mentioned, I haven't experienced any disconnects, modem restarts, or connectivity issues since the install but I know that range is close to the max accepted tolerance levels for the modem. Is there any way of reducing the upstream power, knowing that I still need to have 2 splitters? I have seen some splitters that have a lower db loss that I could potentially switch out, but I'm not even sure if that'll make a difference to the upstream power levels. (I've seen a 2-way splitter that has a -3.7 db loss vs. the -4.5 db loss I have now installed).

One option addressing the modem signal level as well as future DOCSIS/MoCA signal conflicts would be relocation of the modem to where it can have a separate direct connection with the ISP, isolated from the MoCA coax. Or, as-is or as a prerequisite to relocation, running an additional coax line to one of the three Orbi device locations, enabling the separate isolated modem connection.

3. … I haven't logged into the GoCoax web interface yet - do I even need to
If they’re working, no.

4. There's a MPS (MocA Protected Setup) button on my GoCoax adapters - is this something I need to turn on or necessary?
With a “PoE” MoCA filter securing your network, not really. For the most paranoid, if the MoCA-infused coax extends into any publicly-accessible space, MoCA security could be used to ensure no foreign adapters could get connected.

Thanks so much!! As far as the above, I'm curious on what your options would look like in a schematic diagram based on the setup I've provided.

AFAIK, Xfinity internet comes through a single cable in a closet on the first floor of my house. That's also where all of the coax lines lead to the respective rooms in the house (1st and 2nd floors) that have coax jacks. All of my networking stuff (ie. modem, Wi-Fi router) is in my office and my office has 1 coax port. I've already swapped the 2-way BAMF (5-2300 Mhz) splitter for another one with a -3.5 db loss and it really didn't help at all - instead, the upstream power levels increased by .5-.6 db so I'm at 50.5-51.5 dbmV across the upstream channels!

I've been looking at ways of potentially reducing a splitter somewhere in my current setup but I haven't been able to find another option that works, to reduce my modem upstream level power. My GoCoax adapaters only have 1 coax MoCA port, unlike the previous versions which had 2 with one of the ports I understand being a passive 'built-in splitter'.

Title: Best powerline equipment when GFCI is part of the picture?

Background:
The house and my extra building with office are both on the same panel
Panel has a whole house surge protector (it's SW Florida)
No GCFI breakers in the panel but extra building is close to or 100% GFCI (per code) except for A/C unit
The exterior walls of both are concrete block with stucco
There is continuous concrete between the two buildings
Already exhausted connecting the two together with wireless
Utilize two sets of Netgear Powerline PL1010V2 adapters (have multiple distinct networks), 1x1 and 1x2
Just changed from Xfinity cable to Frontier fiber and have an Frontier Arris modem (no Eero)
The new equipment location changed to my wife's studio
All outlets check out as being properly wired
The 120 VAC outlets nearest the cabinet where the equipment is located provided 0 (zero) service to my office
Another outlet in office provided poor service to my office
Another outlet provides marginal service to the office so that's what they are plugged in right now
The studio is likely behind a GFCI that was installed when the living room got floor outlets

Question:
What product(s) would be advisable in this situation?

[Assistant]
If you have a spare rg6 coax between the two locations, moca 2 or 2.5 will be much faster and more reliable.

the issue could as simple as corroded connections in the electrical panel or outlets and whatever else that is plugged into those circuits and others feeding back into the house wiring. Hire an electrician to do any cleanup work.

GFCI should not interfere at all (as long as it isn't tripped).

As @degrub mentioned, MOCA will be leaps and bounds better than powerline.

oldserverguy said:

Enlarge on that, please ... exactly what did you try?

I'm wondering if point-to-point wireless gear could help you. I concur with the other responders that if MOCA is possible then it'd be better than powerline --- but of course, coax isn't going to magically appear if it wasn't built in.

Title: Recently recieved a modem replacement after old one died. Now my moca wont let it connect!

Hey! After a power outage, my old router (arris TM1602) completely died. I went to Spectrum and received a new one (es2251) plugged everything in and activated it things were good. Then power cycled and plugged my Moca adapter in (screen-beam ecb6250) and the modem went offline. Since getting my new router I can't get my moca adapter to work again. I've seen a couple of suggestions here. it's possible that it's because the new router is Docsis 3.1, or maybe the modem is just not compatible with Moca. I would love some suggestions on how to get things working again. I also purchased a Moca filter and it's on the way. anything helps!

(p.s. i have the modem and the moca adapter coaxes connected via splitter, and the router to the moca. Then running the my basement, where all of the coax cables connect, then to my room in the basement where the other Moca lives.)

[Assistant]
The new DOCSIS 3.1 modem is likely sensitive to MoCA signals. Installing a MoCA filter directly on its coax port, as a prophylactic, should resolve the issue.

Depending on when the new filter is due to arrive, a short-term workaround would be to adjust your MoCA network to operate in the D-High frequency range, 1350-1675 MHz, above the D3.1 “initial rollout” max frequency of 1218 MHz.

Title: Home network setup help

Hi everyone!

I’m absolutely new to networking and hoping to set things up our new home to allow the family to work and play without seeing dreaded buffering or latency problems in the years to come!

Unfortunately the house is not wired for Ethernet but it does have coax wired to the basement and first floor areas already. The coax runs are stapled behind drywall so not that helpful for pulling Ethernet direct lines to these same spots. They do all run to a closet under the stairs where they meet with the incoming RG6 line from the ISP.

Am I setting this network up for success? Should I use MOCA adapters? If I added MOCA adapters to increase speeds where would they need to be placed in this set up? Should I relocate the modem to the network closet in the basement? Are there any other ideas I should consider to help realize the faster internet speeds I am already paying for?

Thank you all very much for reading and for your help!

For a cable modem setup with a MoCA network present, this would be optimal to future-proof the setup for DOCSIS 3.1+, allowing the modem a direct, unfiltered connection with the ISP. Or, if available, a second coax line between the closet junction and some room would allow the modem to be installed elsewhere while accomplishing the same isolation.

NotANetworkPro said:

It depends on the topology you’re looking to implement, which depends on your throughput and budget requirements. Your choices are:
a MoCA access point+clients topology over your coax plant (example), or use
dedicated pairs of MoCA adapters for each coax segment (example); or
a mix of both.
Aside from obvious cost differences, one of the main differentiating factors is that MoCA is a shared medium, half duplex, so the max available throughput is shared by all the active connections, with transfers competing for the available bandwidth like an Ethernet hub of old. For MoCA 2.5, the max shared throughput is 2500 Mbps, so a pair of isolated MoCA adapters would effectively have 1.25 Gbps symmetrical throughput (perhaps capped to 1 Gbps symmetrical w/ GigE network connectivity only), or up to 2500 Mbps unidirectional absent other traffic (and with the requisite 2.5 GbE network gear). Most find the cost/performance tradeoff of using an access point+clients setup acceptable.

Your current setup looks good, at least based on what you have available (if you had a second coax line I'd home run the modem to the first splitter, but you don't). Are they all 2 port splitters? If not, reduce them to 2 port to reduce signal loss, since you only need 2 ports on each.

Technically you could replace the 2 basement splitters with a 3 port that has one -3.5 port and two -7, but internally, it is literally exactly what you have now, two 2-port splitters in series, so unlikely to make any difference (a tiny bit less noise maybe, not enough to worry about).

MOCA is only needed if you want hardwired ethernet between the two floors, is that needed? If you're using wireless for everything, looks like you're set up as good as you can be with the existing wiring. Personally I'd want the router on the 3rd floor probably but as long as you have good signal everywhere, not something to worry about (especially if you don't have coax to 3rd floor). But MOCA will steal bandwidth from your modem too, depending on your speed tier and DOCSIS technology in your area, may or may not be a problem (at least currently).

If your modem has poor signal from the cable company, moving it to the basement and the 1st splitter could help, but then you need to run MOCA up to the router since the router in the basement will not give good wireless coverage to the upper floors probably. In reality if your cable can't handle the -7db drop of those two dual port splitters, they need to come out and check the lines to your house and the node on the street. Moving modem to the basement would gain you potentially 3.5db but unless you're below -10 right now, that won't make any difference.

FYI… MoCA adapters with an RF pass-through port would simplify the setup *IF* the CATV set-top boxes do not also require MoCA connectivity. (The pass-through port severely attenuates signals at MoCA frequencies.) Otherwise, lacking pass-through or if the STBs require MoCA, use splitters designed for MoCA 2.x, like the Antronix MMC1002H-B series, right-sized to minimize losses.

Title: MoCA in UK

HI,

I am based in the UK, and am looking into using MoCA to replace my PowerLine adaptors due to having FTTP installed (I have Coax sockets in all required rooms used for UK TV).

Amazon sell the GoCoax 2.5 adaptors, which are the ones I am looking at, however, in my loft I have an 8-way amplifier and splitter combination, and old VideoLab T103C. The only info I can find states a frequency range of 40-890Mhz.
GoCoax said their adaptors may well work, but if they don't, am I better off getting a new amp, with one input and one output, then put a MoCA compatible splitter on the output as all the amplifier \ splitter combos I can find in the UK have the same frequency range.

Thanks

I would use equipment rated for TV and MoCA 2.5 frequencies, 5-1675MHz or better, wherever you need MoCA to pass.

I would use a -70dB LPF/POE filter wherever you want to block MoCA signals such as at an ISP WAN cable, OTA TV antenna, and perhaps at media center equipment in case it doesn't tolerate MoCA(?).

I recently added MoCA 2.5 over an existing OTA TV coax... works well:

I'm about to order a set of ScreenBeam MoCA 2.5 adapters ECB7250: Amazon.com: ScreenBeam Bonded MoCA 2.5 Network Adapter for Highest Speed Internet, Ethernet Over Coax - Starter Kit (Model: ECB7250K02) ScreenBeam appears to be a retail outlet for Actiontec(?), so I'm assuming these adapters...

Yes, but with a “PoE” MoCA filter installed directly on the splitter’s input port, between the splitter and amp.

If the amp is for antenna signal, it’s best moved closer to the signal source, anyway.

Thanks for taking the time to reply.

As there doesn't appear to be any amplifier \ splitter combos in the UK, I guess I am looking at something like (sorry about crude diagram):

With the amp being a 1 source and 1 output.?

I'm guessing I should try with my current setup first, just in case it works?

Title: MOCA amplifier setup not working

Hello all,
I purchased the Commscope MOCA amplifier CSMF1APDU9VPI in order to mitigate noise and amplify the signal in my house. However, the connection diagram as noted on the box is not working for me. The only way the amplifier works is if a I connect all my output cables along with the input signal to the output ports and plug the 15V power to the output port 1. I am not sure if this is correct, since I am not seeing any improvement and the HITRON MOCA adapters drop connection every few hours.
I have checked the speeds and with the amplifier and without (by connecting a Holland 3-way splitter) the amplifier and there is no difference.

I am trying to get the most out of this installation since I have older RG59 coaxial cable inside of my house. I am attaching the diagram for my setup here which is not working for reference. Any help would be much appreciated.

[Assistant]
I'm pressed for time, so gotta be brief. Cable amplifiers don't amplify MoCA signals (at frequencies 1125-1675 MHz), just those within the typical cable TV range 5-1002 MHz. Worse for the specific setup diagrammed, one "designed for MoCA" aspect of the pictured amplifier is a built-in "PoE" MoCA filter, likely attenuating MoCA signals by 35+ dB between the input and output ports.

If you don't have cable TV or Internet (DOCSIS) signals requiring amplification, the setup shouldn't include such an amplifier.

FYI... Cross-posted to reddit sub /r/HomeNetworking:
https://www.reddit.com/r/HomeNetworking/comments/wml6jy

I have removed the Commscope MOCA amplifier, and have also replaced the HITRON MOCA 2.5 adapters with Motorola MM1025 adapters. The DL speed has improved even more, and I am seeing marginal improvements for the UL speeds. I will stick with this setup for the foreseeable future.

However, I have run into another issue noted in this new post

Title: Gocoax WF-803M insertion loss?

Does anyone know the loss between the Moca in and TV out port on the WF-803M.
If the TV out port isn’t amplified my guess is at least 3.5 db.
I am trying to determine why I am getting low signal levels at one of the adapters.

[Assistant]
about 3.5 dB insertion loss. Internally, no loss.
TV out doesn't affect the MOCA signal reception.
Should be about 40 dB budget for the MOCA modems, so likely an issue in a termination or cable or splitter.

best bet is to draw up a sketch with all of the cable paths between the moca nodes and count of the losses for each path. Usually the cable doesnt matter too much unless it is RG59 but you may need to count it if the budget it close.Sometimes you have to use an unbalanced splitter or a powered zero loss splitter to overcome too much loss. Also, make sure you have a moca POE filter at the head end and all terminations not used are terminated with a 75 ohm cap. reflections can generate noise that drops the SNR and causes issues.

Can you get into a diagnostic page on the moca modem and see the power levels, sync, and SNR ?

I found the problem.
Cable is over 70 feet of RG59.

Title: Help with Frontier and MoCa

Hi there,

I recently moved to a new home and unfortunately found out the house did not have ethernet running through the house but instead had Coax. Frontier came by and installed the 2Gig package. The installed a new black ONT box outside the home. From the outside box, they connected to office Coax and then in the office they installed a small MoCa adapter. I have a small office upstairs that I need to have hardwired and the mesh network isn't super reliable. When I called Frontier, they say I can install a MoCa splitter (which I bought) from the ONT and connect all the coax cables (which I did) and then use a set of MoCa adapters (got the goCoax adapters) but when I plug them in and try to run ethernet to the PC i get nothing. What am I doing wrong? I'm sure I don't really understand MoCa or how to run the adapters but here it is:

ONT >> MoCa Coax Splitter In >> Out to Office Coax, Living Room Coax, Upstairs Room Coax>> Office Coax >> Frontier MoCa Adapter >> Linksys Velop Router (Mess Network with 3 nodes) Works but Living Room Coax >> goCoax Adapter and Upstairs Room Coax >> goCoax Adapter doesn't work.

I hope this helps paint a picture but I'm super lost right now as to where I'm stuck or what to do.

[Assistant]
Welcome to the forums @mocanewbie.

I may not be understanding this fully, but I think splitting it at the ONT is wrong. Unless you have multiple WAN IPs.

Hey @L&LD, I think you're right. I will admit I am completely lost right now. All I want is to just have ethernet in 3 places in the house. Office, Living room and upstairs bedroom. I think the only way to achieve that is to have the router close the box outside the house and then somehow MoCa things out.

As far as I know Frontier is still using MOCA-WAN for the connection between the ONT and router and MOCA-LAN to connect to the set top boxes (sharing the same coax cables for both).

You can get frontier moca adapters off amazon/ebay for $50 and under, if you are using their router, it should have MOCA LAN support built right in and those adapters will connect to it through your existing coax cabling, same way their set top boxes connect.

Where do your coax runs terminate - are they all at the fiber ONT box? If so that may be where you need to put the splitter, as long as it is MOCA compatible it should be fine.

If they've changed to using some other setup, you may need to isolate the coax cables you want to use for LAN and put a MOCA adapter on either end, which effectively just converts each coax to an ethernet cable. Some MOCA setups will let you use a single adapter at the router LAN and then put 3 remotely in the house (with all 3 coax running off a dedicated splitter). Others have to be installed in pairs, in which case no splitter needed, just have 1 coax per pair of adapters (this will be the fastest total throughput and least amount of potential issues too). But it is also the more expensive option.

I'd check on the router they've given you and see what MOCA standards it supports. If they haven't changed anything from my assumption above, just buying a few Frontier branded adapters (which are just rebadged Actiontec I believe) is probably cheapest and easiest.

Title: MoCA and a Rat's Nest of Coax

I was directed to this forum by someone after they told me about MoCA.

My parents moved to a large house. They have a Netgear Nighthawk X6 that covered there previous home but wasn't sufficient here. They picked up some EEROs for a mesh network. I want to utilize the Nighthawk as an AP for extended coverage, particularly near the living room where there is high traffic (TV, phones, computers, wifi cams, etc.), but it needs to be connected via ethernet.

Their home was built in the 80s. Prior owners had a security system that included, among other things, cameras. It's an old security system that isn't worth saving. However, we found a security recording system that had a large number of coax cables going into it, which leads me to believe the cameras are wired via coax.

This recording "box" was found on the first floor in a cabinet with a ton of wires coming up through the floor. These are the only coax cables on the first level on the house, and they are terminated with non-traditional ends.

There are 4-5 coax cables/ports on the second floor of the house. One of the ports is what feeds the modem on the second floor. It's not situated in the most optimal location of the house. We wanted to move the modem to another location on the second floor (as the router has to be connected via an Ethernet cable).

We looked in the attic (where there are another ~20 coax cables) to see if we could trace the cables feeding the modem, but we were unsuccessful.

(It was at this point my parents ordered 3 EEROs).

After setting up them up, I wanted to see if I could use the Netgear in AP mode, so started doing some research and someone told me about MoCAs and directed me here.

Ideally, we run new ethernet cable, but that is not an option.

Next best thing seems to be MoCA.

I know this is a broad question, but where do I get started?

The ends on the camera runs are likely BNC ("push and twist lock") right?

If so those are easy to differentiate and track down, each one will be a home run to a camera, there are no splitters or anything else in the path (unless it is a very non-standard system).

Assuming they are decent (ideally RG6, should say so right on the cable, hopefully Quad shield but double shield probably ok). RG58 will work but may not get up to full MOCA 2.0 or 2.5 speeds.

You can either get BNC female to F male (screw on style, like cable TV) adapters, or cut and re-terminate the ends. If you don't have the tools to do that, better to just get the adapters.

You'll need to track down the other end of each wire, disconnect it from the camera, and pull it back to somewhere that it is useful.

Alternatively you can totally ignore the BNC camera stuff and focus on regular coax that has screw-on connectors which will be feeding your modem and TV jacks. You'll start at the entrance to the building and trace it from there, finding splitters, etc as you go, and labeling which ones go to what, one will go to modem, some to set to boxes, some may not be used and just terminate in various rooms with nothing connected. Often there will be multiple splitters in the path and it is important to note where each one is as you map it out on paper.

You can pick up something like the Klein VDV Scout series from Home depot which makes it easy to trace multiple runs. Or just unplug/plug one thing at a time from splitters you find and label what they are for.

Once you've found what each one does and where it goes, then you can start getting an idea of your options for MOCA. The camera runs may be ideal (since they are dedicated runs, no splitters, and nothing else on them) if you can get them into places where you need them, but most likely that would require pulling cables back from outside of the house etc so may not be feasible.

Next best thing seems to be MoCA.

I know this is a broad question, but where do I get started?

Given you are admin for the parents, I would prefer to keep it simple... all eero nodes.

I recently deployed MoCA. Ideally, isolate a healthy coax run from your rats nest of coax and connect a MoCA 2.4 adapter to each end to connect Ethernet. Remove any non-MoCA splitters in this coax segment. Do not connect this MoCA coax to ISP/neighborhood coax without installing an intervening MoCA filter to block your MoCA signaling from broadcasting to the WAN.

The latest MoCA 2.5 adapters with 2.5GbE ports do not seem to include the integrated MoCA splitter, so if you go for MoCA with 2.5GbE ports, plan to add external MoCA splitters if you need to extend the MoCA network.

if it is RG-58, it is iffy to work unless the run is short, the cable is in good condition, and point to point. It has a lower impedence (50 ohm versus 75) and higher loss per ft of cable compared to RG-59 or 6.

from wiki -
"Its signal attenuation depends on the frequency, e.g. from 10.8 dB per 100 m (3.3 dB per 100 feet) at 50 MHz to 70.5 dB per 100 m (21.5 dB per 100 feet) at 1 GHz"

RG-59 is about 8 db/100 ft at 1 GHz.

The higher the operating frequency the higher the loss.

MOCA operates between 1.1Ghz and 1.6 Ghz.

MOCA modems have about 40 db of power budget to work with. So maybe,

Hopefully there are no splitters in the walls as you will have to find them and replace
