Title: MOCA newbie and our home network

For those who've been following my saga on routers, I'd like to ask some questions. We had a network wiring consultant look at our setup today and he proposed considering using MOCA to get more throughput to our home offices and possibly our home theater. Our problem is that the in-wall wiring was basically CAT 5 (not 5e) and is essentially repurposed POTS telephone line. Also, some of the lines were (per the guy who originally converted the telephone lines to Ethernet) questionable in terms of quality and may have been stapled causing breakage.

Reviewing getting CAT 6 to our critical locations (two home offices plus home theater / media center) will be tough. The home theater may be doable (downstairs and could be accessible) but the location of the main can for cable coax and phone lines is at one end of the house (upstairs master BR) while the home offices are at the other end and there's no easy access via the attic to any of the existing drops. What we DO have is COAX going to each home office and the home theater. The COAX is occupied by a TV settop box in one home office and a DVR at the home theater.

I don't know a thing about MOCA compatibility with our Spectrum DOCSIS 3.1 modem but the relevant specs seem to be as follows:

Downstream:
Frequency Range: 258MHz-1218MHz
Capture Bandwidth: 1.218GHz
Modulation: 64 or 256 QAM and OFDM: up to 4096 QAM
Upstream:
Frequency Range: 5MHz ~ 42MHz/85MHz switchab
Modulation: QPSK or 8/16/32/64/128 QAM and OFDMA: up to 4096 QA
Here's a diagram of the mess.

Any thoughts are welcome! Note that I have to keep the 2.4 & 5 bands separate since our cams get confused if they share an SSID. Also, as it stands, I'm really not using anything on the 5ghz band except for cell phones & things that don't require 2.4. All the brown items are 2.4 only. Home Office 1 has the set top box, TV and Fire Stick.

[Assistant]
I vote do Cat6, or don't do anything at all.

Bite the bullet and do it once, but do it right.

I would run multiple Cat6 runs everywhere you can. Options in the future are priceless, vs the cost to redoing it then. (Or, having to work around the limitations you create (at usually suboptimal levels).

With a home theater, two offices and other connected needs, along with the questionable wiring already confirmed within the home, the cheapest way to a solid and reliable network is to do it right. From the beginning.

There is no time better than now. Future work is always more expensive.

I added a MOCA 2.5 wired backhaul to my AiMesh. I was able to dedicate a coax segment to the DOCSIS3.x modem link to avoid any interference between MOCA and cable modem signaling. Otherwise, you may need to configure the MOCA adapters to avoid your DOCSIS signaling frequencies, now and future.

If your tel/Ethernet wiring is damaged, your coax may also be damaged... only use the coax segments you need to hopefully avoid any unhealthy cabling/transmission characteristics.

OE

You may need to research this further, but a lot of times ISP equipment connected to coax is already using moca or has the capability, and/or can run over ethernet. So for example, in the case of the dvr box, you may be able to put a moca adapter to get ethernet to it and then connect it via ethernet instead.

Title: How to set up MOCA network with only one splitter?

I posted this recent thread where I described problems I had setting up my Asus ET12 with ethernet backhaul over MOCA. It appears that the problems were rooted in poor cable signals and too many splits. After removing all the splits and having only one direct cable into the house, my network problems disappeared. However, I also gave up the MOCA and wired backhaul by giving up the splits.

After testing the tolerance of my house for splits, it looks like I can only handle one 2-way split outside the house without negatively impacting the signal at the cable modem. With one split, modem goes from 42 to around 45 for upstream power and +5 to around 0 for downstream power, and no errors. However, as soon as I introduce the split just before the cable modem and MOCA, modem starts to test its tolerance limits by being around 50 for upstream power, and corrected and uncorrected errors start to appear in the modem diagnostics.

I've attached a diagram of the moca setup with two 2-way splits. I'm wondering if there's any way I can remove the 2-way split just before the cable modem/moca adapter so that I just have one split in my network and I can keep the network issues from cropping up.

Wondering if the Motorola MM1025 would be a better choice with its 2 coax ports....coax cable from wall into Motorola "network" coax port, "device" coax port output to cable modem, ethernet cable from cable modem to router, ethernet cable from router to network switch, ethernet cable from network switch to Motorola ethernet port....unless the Motorola would have the same impact on signal strength as the splitter

This comment on Amazon tells me that I could do this and the Motorola would not cause the same signal issue as a splitter.

It’s critical to understand that any MoCA adapter with a pass-through coax port is using a diplexer (parallel filters) internally, and not a simple splitter, to splice the signals, resulting in the pass-through port only passing frequencies 5-1002 MHz. For this reason, no devices requiring MoCA connectivity should be connected through the pass-through port (e.g. Xfinity X1 and FiOS STBs).

So I'm assuming that the Motorola will simply pass through the cable frequencies up to 1 ghz to the device port, and it shouldn't interfere with my DOCSIS 3.1 MB8611 modem as the upper range of the frequency for that modem is 1 ghz.

you will be lucky if the isp stays below 1005 MHz. with DOCCID 3.1. Once they cross you will loose bandwidth or they will remove moca in their path. Better strategy would be to fix the cable paths, possibly run an internal cable or two. Maybe just use CAT5e or CAT6.

Title: Asus MA-25 for wired backhaul only shows 1 gig connection on Asus ET12 satellite

I recently purchased two Asus MA-25's to set up a MOCA network with 2.5 gig ethernet connections (previously I had Actiontec 6250's with the 1 gig connection). I also got the Asus Zen Wifi ET12 which has a 2.5 gig wan port and also a 2.5 gig LAN port, using one of the Mocas for wired backhaul on the Asus satellite.

The Moca's are showing a successful connection, and I've got successful wired backhaul on the ET12 satellite on the 2.5 gig WAN port of the satellite. However, in the Asus web GUI, it says it's a 1 gig connection on the 2.5 gig port. When I test wireless speeds on both the 5 and 6 ghz channels near the wired satellite, I get 800-900 mbps also suggesting it's a 1 gig connection. I'm eventually going to test the 2.5 gig LAN port on the satellite with my laptop but need to get a 2.5gig adapter first for my laptop, so right now I can only test the speed wirelessly.

I have Xfinity service up to 1.2 gbps, and I know I'm getting those speeds at the main router as speed tests are showing 1.4 gbps. I've also gotten wireless speeds up to 1.2 gbps on the 6 ghz channel near the main router. My 2.5gig network switch also shows 2.5 gig connection lights for the Asus MOCA adapter that is on the modem/router side of the network as well as for the main router. The connections are also correctly put in the two 2.5 gig (not the 1 gig) ports on the primary ASUS ET12 router. Thus, there's no rate-limiting network port that would be slowing my speed for the entire MOCA network (i.e., like if I had a 1 gb ethernet switch rather than 2.5 gb or if one of the MOCA adapters had just a 1 gig ethernet port or if I had a cable in one of the wrong ports on the router).

I've read the MOCA 2.5 is half-duplex, which effectively makes it 1.25 gig up and down. Would this be why the ET12 satellite is showing the backhaul connection as 1 gig? This would contradict Asus's claims on the MA-25 that you can have wired backhaul speeds up to 2.5 gbps.

[Assistant]
between two nodes you get 2.5 Gbit/s but only half of the time in each direction. It is a property of RF communication. Looks like a perfect match with the Verizon service. If there is a sync diagnostic page on the MA, check the bit rate sync. i have the same thing with my GOCoax modems on ATT 1 Gb fiber.

Replicating my reply from Reddit: Absent other competing traffic, MoCA 2.5 adapters equipped with 2.5 GbE ports should be able to communicate at up to 2500 Mbps in a 2-node-only setup. (Up to 2000 Mbps in a 3+ node setup, with the “TURBO” boost lost.)

One example from a recent Reddit thread:
When I first tried the parallel streams I was doing 4 and thats what got my the 1.33Gb after seeing this reply I decided to try different numbers and with 10 streams I got 2.26Gb

Thanks for your replies.

I think the issue is with the quality of my cable connections. This morning I woke up to the ET12 satellite being offline, then came back online. After coming back online, it said it had a 2.5 gig connection. However, the ET12 kept going back offline and coming back online over and over, and when it was online and I tried to test the internet it was either really slow or wouldn't connect at all. I eventually disconnected it and am using wireless backhaul for now.

I know I have some issues with cable connections in my house, because last week I tried to move our cable modem from office to master bedroom and the modem had troubles connecting so I moved it back to the office. And in the office itself, while the internet is working fine, if I look at my cable modem diagnostics the upchannel power is a bit high and beyond spec for Xfinity (53-54 when it should be under 50), the downstream channels power are a bit on the weak side (but still in spec) at around -6 to -7, and I have quite a few corrected and uncorrected errors.

In the past I had just run our downstairs TV directly from the MOCA, and given the connection is only a 10/100 connection, cable quality probably wasn't enough of an issue to impact TV streaming performance so I never noticed it. But now trying to connect the ET12 satellite there, it probably magnified the problem so that it became apparent.

I don't have a ton of splits....one 3-way split outside the house after the mainline (splitting the line to the office where modem is, bedroom, and downstairs TV), then a 2-way splitter just before the modem to connect the modem and MOCA. But it's a 1980 house and I'm guessing the cable quality isn't high.

I have an Arris active return amplifier coming today that I'm going to try to boost the connection signal. I'd like to try to avoid having to re-run new cable (or try running ethernet throughout the house).

Title: Why can’t I use the CommScope CSMF1APDU9VPI?

My ISP installed a CommScope CSMF1APDU9VPI, in order to get signal to all of the rooms. Now we are cutting the cord, and I would like to repurpose the individual coax legs for my Gigabit Ethernet LAN. I have purchased a set of MoCA units (ScreenBeam ECB7250).

When I use them in a direct link they work beautifully. When I feed the coax out of the one by my router into the IN port of the CommScope amp and hook up the other at one of the amp’s outputs, I can’t pull an IP from the router. The communication has broken down.

A ScreenBeam tech support agent claimed that my problem arises from the fact that the CSMF1APDU9VPI is not compatible with MoCA, even though it calls itself a MoCA VoIP Amp.

What is the truth of the matter?

[Assistant]
DominikHoffmann said:

It’s a “designed for MoCA” amp with a built-in “PoE” MoCA filter, so no MoCA traffic is allowed between the input port and the outputs; it’s designed to allow MoCA traffic to flow between all output ports, including between the passive output and the amplified outputs.

https://www.commscope.com/product-t...ers-components/rf-amplifiers/itemcsmapdu9vpi/

From the specs tab; the values all seem similar, but note the qualification for “minimum” and “maximum”; input/output path has MIN loss of 35-40 dB; output/output paths have MAX loss of 35 dB.

You could probably get the adapters to link if they were directly connected to the input and output via a short coax, but in their regular locations the additional attenuation of the coax, connections, and other splitters likely puts the path loss above the 57 dB loss limit.

Now that you know, what doesn’t work, do you know, what I should replace that with?

Title: Here we go again (MOCA)

I have Spectrum Cable (DOCSIS 3.1). When I originally setup my GoCoax 2.5 adapters, I couldn't use Exteneded Band-D because of frequency overlap(DOCSIS 3.1 caps at 1218mhz, not 1005mhz like DOCSIS 3.0). So after studying the frequency charts I ended up choosing Band-D High and setting the LOF to 1350. It's been perfect for nearly a year. Then today all of a sudden I'm capped at 16MBps(130mbps) over MOCA 2.5. This was true for WAN and LAN file transfers. I just spent 2 hours messing with the adapters and got absolutely nowhere.

1: I tried putting them back in Extended Band-D again, and when I did that my Modem immediately dropped its WAN connection.
2: I saw there was a new firmware update, one of my 3 adapters apparently was on an old FW so I updated that one.
3: I set them back up the way I had them (-Band-D High and LOF to 1350)

Same results, stuck at 130mbps. I checked the PHY rates when I connected all 3 adapters back and they are all bright green (showing MOCA 2.5 speeds). I'm so confused

[Assistant]
Check the ISP modem to see what bands it is using. Talk with your ISP to see if they pushed an update to you recently. Or maybe you can see it in the modem logs/config pages.
Log into your moca modems and check the sync speed table for link rate between nodes. if everything looks normal for dHigh, then it is likely something else, maybe in your pc on the ethernet ?
what is your coax network topology ? a sketch showing everything that is connected and the coax runs would really be helpful.

can you isolate moca from the doccis portion ? It may take a few more moca splitters and moca POE blocks.

Are you using iperf to measure speeds with different devices across the moca links ?
what were the measured values before ?

My modem is a Hitron E31T2V1 and I don't think it has a UI that you can log into like you can with those "all in one" modems. I was getting gigabit speeds for a year on LAN until yesterday (windows copy to nas). I tried a USB 3.0 to ethernet adapter as well and same issue. The topology is the POE coax connecting to a 3 way splitter and splits off into 3 rooms. It has to be something wrong with one of the adapters or modem. But also when on wifi I get the full internet speed. So the issue is somewhere in the moca network. I can't use a POE filter because nobody makes one rated up to 1218mhz yet. I feel like I need to figure out which moca band and LOF to change. Or maybe an adapter went bad? I don't think Spectrum could have changed anything because I looked up the Hitron and everywhere I look it's the same frequency range (5-1218mhz).

the green light usually just means that the modem sync'd with another modem. They might be syncing with the ISP modem instead. More likely, the two are interfering with each other. Take your moca modems and use a spare piece of coax at least 1 m long and test each pairing to see if there are any issues. There is a diagnostic page for the gocoax modems that shows the bit rate sync table. Search the threads here. i think there was one thread opened by gocoax as well.
Your description indicates interference. If the ISP modem is not playing by the rules, you may have to isolate the moca 2.5 coax.

reading this reddit thread
that modem appears to have the PUMA 7 chip set which may be the issue. Talk with spectrum about using your own modem or look at their support pages for compatible modems. You want a Broadcom chipset.

Title: Which one is not functionning properly ECB2500C ou WCB3000N ?

Hi,

I bought approx 2 years ago an Actiontec WCB3000N Wireless Network Extender with MoCA and Gigabit Ethernet - Wi-Fi range extender - 802.11b/g/n - Dual Band - with Actiontec ECB2500C MoCA Network (WCB3000NK01). They have been working fine for 2 years

Suddenly the wifi (2g and 5g) is not avilable in the room upstairs and the COAX light on both devices is off. The wifi is of course brought over there by COAX cable. I made a continuity check with a Sperry Cable tester and all the COAX wires and junction connectors are functionnal. All the testing I did is pointing to the Actiontec devices.

After the continuity test, in order to eliminate the house cabling, I brought the ECB downstairs close to the WCB, connected both with a short COAX cable, still both COAX light are off and no wifi connectivity.

My question

How can I determine which device is not functionning properly, the WCB or the ECB. To replace the faulty device, I need to know which one is not COAX capable anymore.

Thanks,

Michel.

[Assistant]
The WCB has Ethernet ports, so you should be able to connect a laptop or PC to the WCB to test its coax/MoCA connection separate from the Wi-Fi access issue.

MChevrier said:
I tested the WCB/ECB kit for RJ45 connection and the kit is functionning.
If this statement is saying that you *did* test the connection via the WCB’s network ports and that it worked, then the issue would seem to be internal to the WCB and its Wi-Fi setup.

But on both devices the COAX light is off, that is why I am concerned with the COAX capabilities of the ECB/WCB team. I modified the original posting to add information that might shed sone light on the issue.

Title: MoCA 2.5 Packet Loss (GameStream/Moonlight Stuttering)

I have a gaming PC in my bonus room, and I use GameStream/Moonlight to stream games to an NVIDIA Shield Pro in my living room. My network consists of three TP-Link Deco X60 mesh routers with three GoCoax WF-803M MoCA 2.5 adapters (see attached network diagram.)

I stream at 1080P 60FPS and it usually works great, but there are quirks that are most noticeable in side-scrolling 2D games. Running the original Super Mario Bros. in an NES emulator, Mario "teleports" for a split second once every 15-20 seconds. I use Moonlight's "Prefer Smoothest Video" mode, and the teleporting happens regardless of what bitrate I stream at (0.5Mbps, 50Mbps, or 150Mbps.)

At first I assumed this happened because MoCA adds 3-4ms of latency, but I'm wondering whether it's related to packet loss. I got the attached results from an iPerf3 server on the Shield and a client on the gaming PC. Throughput is >900Mbps when I run 10 parallel streams, but the UDP tests show packet loss. Also, my GoCoax status screen (see attached) shows "Rx Bad" packets.

If I move the Shield to my bonus room, I connect it to the same unmanaged gigabit switch as the gaming PC. Presumably it never touches the MoCA network. This eliminates the packet loss completely, and it prevents the teleport glitch in SMB.

I've tried quite a few things to improve MoCA performance, including:
Replaced an older amplifier with a MoCA-compliant Holland splitter
Put 75ohm terminators on every unused coax connector
Added Antronix MoCA filters to my point of entry, modem, and STB
Replaced old barrel connectors with Holland 3GHz barrel connectors
Replaced all coax patch cables with new RG6
Short of replacing the in-wall coax (at that point, I should just install CAT6), is there anything you'd suggest looking at to avoid the packet loss, or is this inherent to MoCA?

[Assistant]
You will have to isolate elements in the coax plant as much as possible to figure out where the issue is.

run your test without the Holland splitter. ie point to point between the two locations of interest. You can either use a RG6 barrel connector (union) to connect the two coax or get another GOCoax modem and run two pairs with an ethernet cable between them.

to try to track down which segment of cable might have an issue with packet drops, you will have to pair up two GoCoax and run the test over just one segment of cable. Of course that doesn't tell you if it is the coax or the terminations. Most likely it is a termination or possibly a slightly loose connector on the wall plate. You may be able to pull the wall plate and connect the GoCoax modem directly to the cable in the wall on the cable segment that shows packet errors.

i suppose it could also be an issue with one of the modems as well. Gaming will definitely stress a system. You could get a 25 ft or whatever length you need of pre-terminated RG6 and test the modems alone to see if it is in that part or the in wall coax plant.
i don't know what the 1-2 msec lag will do to your gaming, but i would be surprised if it caused packet loss.

Thanks for the suggestions! I'll try to isolate it this weekend.

Last night, I ran some tests with PingPlotter and noticed that packet loss only occurred with data sent between the Bonus Room and Living Room:

To Study
To Bonus Room
To Living Room
From Study
---
Good
Good
From Bonus Room
Good
---
Packet Loss
From Living Room
Good
Packet Loss
---
Since all the coax segments go to the Holland splitter, I would expect that if a segment or router were bad, this would affect all traffic involving that room. For example, if the Bonus Room was bad, I would expect packet loss with both Bonus Room <-> Study and Bonus Room <-> Living Room. Thoughts?

It depends on the total apparent length of cable path between the two modems, if one modem is having a hardware issue, one cable is crimped or nailed, broken sheath, or a sheath wisker is near the core conductor, faulty port on the splitter, total number of connections, etc. in older cable there may be oxidation at the contact between the core conductor and the receptacle. Many times it is a combination of issues that provides the straw to break the camel’s back. Thats why you have to carefully and systematically try to eliminate causes by isolating and testing.

i just noticed you have a three way splitter. Which 3 ports are you using ?
Moca modems have about 40dB of power budget if i remember correctly. Usually, that is more than enough. If the packet loss goes away when you eliminate the splitter, see if you can call up a diagnostic screen with the output power usage on the modem with and without the splitter. There was a reason the previous installation had an amplified splitter.

Title: MoCA 2.0 Actiontech ECB6000

I purchased a pair of Actiontec ECB6000's, which are MoCA 2.0 (100 MHz single channel - "Baseline Mode"), and installed them yesterday. Consistently getting >325 Mbps (max I have seen is 350 Mbps). The ECB6000's replaced a pair of Actiontec ECB2500C's that got 95 Mbps. This is on a dedicated run of coax from first floor to second floor. While Actiontec cites the 670 Mbps PHY rate, the MoCA Alliance site says you can expect 400+ Mbps MAC throughput from MoCA 2.0 Baseline Mode.

I have not seen the ECB6000's advertised, but you can purchase them from Actiontec's online store.

-pc

[Assistant]
Fantastic news. I've been waiting for Moca 2.0 adapters to finally come to the consumer.

I just got a pair of these and on a shared cable tv line with 2 splitters I'm getting about 50~70 mbps, the same as moca 1.1! I think they need a dedicated cable to perform at 2.0 rates. I don't have that so I'm going to try amplifiers next.

Dedicated cable should not be required, but I have not tested this since I had a dedicated piece of coax going from the first to second floors. The MoCA field trial preliminary results from earlier this year were >350 Mbps in 95% of their test houses. I am typically seeing on the average ~330 Mbps.

You do need splitters with a 2 GHz frequency response (the 100 MHz channel is between 1.125 and 1.425 GHz).

Title: Translite MoCA 2.5 adapters need reboot every few days...

I purchased a pair of the Translite MoCA 2.5 adapters and have everything set up in my house (including the PoE filter). Throughput is fine, I'm on gigabit service and get 850+ "on the other end". After testing throughput once I was done setting it up, I connected the adapter to a node in my AiMesh setup as a wired backhaul. I haven't yet pinpointed the exact frequency yet but I've noticed that every so often that wired backhaul is disconnected and that my MoCA adapter connected the node has the MoCA light always off. The adapter has a power toggle and once I toggle that off/on the MoCA connection comes back up.

I've never had any issues with throughput so I'm not sure if it's necessarily an issue of signal quality, but I'm not exactly sure what is causing this. Would it be safe to rule out the node itself causing the issue? I might try directly connecting a PC to the adapter instead of the node and see what happens...

[Assistant]
Do you have two adapters direct-connected via coax, or is it a splitter situation? If split, what’s the coax topology? And if you have a cable modem connected to the MoCA-infused coax, what’s its brand & model #?

I've never had any issues with throughput so I'm not sure if it's necessarily an issue of signal quality, but I'm not exactly sure what is causing this. Would it be safe to rule out the node itself causing the issue? I might try directly connecting a PC to the adapter instead of the node and see what happens...
Click to expand...

I don't think the node is causing the MoCA link to drop... more likely the adapter or coax network or interference on the MoCA coax.

I think you can wire the MoCA adapters in a loop to test them... coax to coax, Ethernet to Ethernet... they should appear active and stay active. Then you can open the Ethernet and use them to connect your PC to your router to confirm Internet access... they should stay up. If all of that works as you would expect... investigate your coax network. Know that DOCSIS3.1 can overlap MoCA frequencies.

Do you have two adapters direct-connected via coax, or is it a splitter situation? If split, what’s the coax topology? And if you have a cable modem connected to the MoCA-infused coax, what’s its brand & model #?

Sorry for the ugly mspaint. MoCA Adapter #1 is the one that needs power cycling... Also, the only cable service I have is internet (no Cable TV service).

The cable modem I have should be the Technicolor XB7

Title: MoCA Setup from Media Panel in Garage

Hello,

MoCA noob here. I currently have my ISP modem setup in bridge mode to an Eero wireless mesh and it generally works.

Current network speeds
Eero garage: 600+ mbps
Eero MBR: up to 400 mbps
Eero Sun Room: up to 200 mbps

I’ve tested these across multiple devices and I get these speeds on average.

But what I’d like to do is setup the two Eero extenders in the house using MoCA. According to the Hitron HT-EM4 MoCA 2.5 directions, what I’ve drawn below should work, but before I get too involved, can someone check my approach? What am I missing? Will this even work?

Longer term, if this would work, I’d like to wire the other locations using MOCA as needed, but the two Eero extenders is all I need for now. The blue part of the drawing is what I need feedback on.

[Assistant]
Looks good. Opinions may differ on splitter arrangement of MoCA nodes; my preference is having all nodes hanging off outputs of a designed for MoCA splitter, with a MoCA filter and 75-ohm terminator capping the input port to retain the known reflective benefit of the “PoE” MoCA filter.

Barddzen said:

Do the eero units have 2.5 GbE ports?

As long as all of the MOCA2.5 coax is physically independent from the ISP coax, then life is easy, short of cable/connector/splitter issues. It is when you have to share the cable between MOCA2.5 and DOCCIS3.1 that you loose some of the MOCA bands and throughput.
MOCA nodes time share, so if in the future you want the full 2.5 Gbit/s, half duplex, between nodes, just make each run with a pair of modems and use an ethernet switch instead of the MOCA coax splitter. My system uses MOCA2.5 for the home run between the ISP router and the ONT. All of the other runs are MOCA 2.0 bonded, turbo, and 1 Gbit/s ethernet across a switch built in my internal router. The only contention is between the switch and the routing function to the ISP. Not noticeable in any practical way.

RG6 is the preferred coax, but RG59 should work. Make sure the moca2 splitter is formally certified. Some also have built in MOCA POE filters on the input labelled port.

MOCA does introduce a few msec of latency per node, so if you game heavily, it might be noticeable.

Title: Moca newbie advice

Hi all,

I recently learned about this forum and have been diving into it and learning more about networking since. Thank you for such a depth (and breadth!) of awesome information.

I come, at this time, to seek help. I live in a 3 story, 2800 sqft home. We currently have CenturyLink fiber and are just using the default provided router for Wifi. As you can expect the wifi is very sloppy and keeps dropping every now and then (I'm pretty sure it is the router). I have considered running ethernet cables to all floors to install access points and provide wired connection to some devices (namely the video game, TV and NAS), but this wouldn't be too straightforward given the setup and the age of the home (and my limited funds at the moment). I have also considered a new and beefed up router, but I would really prefer a wire setup because I can use it for the NAS+media.

While browsing through this forum I learned about Moca and was really excited/intrigued because the house has coaxial outlets in every floor. I read more about Moca and it does seem to be suitable for what I need, but I wanted to ask for your expertise first. Please see the image below for a diagram of my current setup (in black) and my idea for improvement (in red). It looks... too simple! I might be missing something completely and/or just not understanding the technology.

Am I missing something here? Would this work or would there be a better setup?

For the coax, there's a wire coming from the utility pole that goes to a 2-split and then two wires go into the house (one for the first floor) and another, I believe, to the basement. There's a room on the second floor with a coax outlet and I have no idea where the wire for that is coming from (or if it works - perhaps there's a split in the wire that goes to the basement somewhere in the wall).

For the Moca adapters, I was planning in getting three of the screenbeam, connecting one to the router via ethernet and then to the coax outlet in the first floor. One the basement and second floor I would connect the coax outlet to the adapter and the ethernet to an AP.

Thanks for the help!

I would fix/improve/upgrade your existing network first before extending it with MoCA segments and APs. Then decide what needs to be done where to extend LAN/WLAN coverage. One, maybe two good APs (including the wireless router AP) can cover 3x?=2800sf. Too much WiFi is not a good thing. Save the MoCA project for last.

Given the fiber ISP and no other services, you don't need nor want the top utility/coax connection. Is your existing coax cabling being used for anything like cable/OTA/satellite TV or cable Internet?

Before adding MoCA, you should investigate/confirm/repair your coax cabling and disconnect/remove unnecessary elements to keep it clean and simple (coax is a multipoint waveguide for radio... like WiFi confined to a cable... it needs to be in good repair and bonded to the building Earth Ground at the demarc). Splitters must be rated for MoCA frequencies up to 1675MHz or higher. Open connections on active coax should be terminated. Each element inserted into coax will attenuate/weaken the signal, so minimize these insertions/losses.

If cable Internet is your backup ISP, it may eventually not coexist with faster MoCA that uses some of the same frequencies, so ideally you would want to keep cable ISP coax separate from LAN/MoCA coax.

Moderator should move this discussion to the MoCA subforum... MoCA not wireless.

Title: Moca Lan IP configuration

My 2 Moca device network works great (2 x Actiontec 7250's) but I have a question regarding IP addresses being generated to devices connected off the 7250's.

I like to setup my router to assign specific IP's to MAC addresses of all my devices. After adding the 2x ECB7250's it seems they are assigning their own IP to my devices attached off of them. My network is 10.0.0.xxx and the devices are getting 10.0.0.xxx but not the ones I am assigning in the router no matter what I try. I went into the Moca setup but wasn't sure what if anything i canselect under DHCP to allow ME to assign the IP's I want to the devices connected to the 7250's. Hoping you can point me to the correct config of the 7250's to accomplish this.

Thank you for any help that you all can provide.

[Assistant]
the modems are basically transparent to your router.
Are your "device" set to get DHCP AUTO address ?
They would show up in your DHCP address leased range entry.

degrub said:

Yes, everything, including what is attached off the Moca adapters, are getting IP's within the leased range which is the full .2 to .254 range. While I am not very familiar with Moca I am pretty knowledgeable in networking so I am familiar with all the basics of DHCP etc. They are NOT getting the IP addresses I assigned to them in "Reserve IP by MAC" in my router's DHCP settings. Anything that is NOT connected to the Moca box is.

Example, I assigned my Apple TV MAC address which is connected to one of the Moca adapters to IP 10.0.0.150 and it gets .43. No matter how many times I remove it, reboot it, reboot the adapters and/or reboot the router it is not getting the IP I have assigned to it on the router. As soon as I connect it to either my switch that is directly off the router or by WiFi it immediately gets the addresses I had assigned to it in the router MAC table. The Moca adapters themselves are getting IP's from my 10.0.0.xxx as they show up in my router NAT table with those IP's.

Edit: My router is actually a gateway, it's a Motorola MG8725 which has the router built in.

Hopefully that made it clearer as to what my issue it.

you need to set the DHCP lease range to not include the hard assigned IP addresses as a start. You may have to hard code the address in the apple device under manual settings for that network. Any chance the apple device is randomizing mac address for privacy ?
i have Actiontec 6200s between my Cisco RV325 and the users. No issues with manual IP address assignment to the devices across the moca network. i did not touch the settings in the moca modems.

Title: Moca amplifier with cable modem

Hi. I have been trying to fix my internet connection without success. I live in Venezuela and the cable company doesn’t send anyone to check the cause of the problem, so I’m trying to find a solution. I have Tv and internet via coaxial wire. The internet service doesn’t work properly. I bought an amplifier Commscope model: CEMAPDU5VPI which has MoCA technology. I’m wondering if a made a mistake buying this amplifier. I’m trying to have a better internet signal. I would need a moca adapter or filter for that? My cable modem is a Netgear CG3100D-28paus. I will really appreciate any help at this respect!!

Any chance that you meant CSMAPDU5VPI?

Regardless, these amps don’t “have MoCA technology” … beyond having a built-in “PoE” MoCA filter and being designed to allow MoCA signals to flow between all output ports, including between the passive (non-amp’d) port and the amplified ports.

Further, if you’re having *Internet* connection issues, a “designed for MoCA” amp wouldn’t be of any more significant help than a MoCA-agnostic amp. A “designed for MoCA” amp would only be needed when an amplifier has been determined to be needed to boost the cable TV (QAM) and/or Internet (DOCSIS) signals *and* MoCA is being used to extend LAN connectivity.

If looking for help diagnosing a cable Internet connection issue, the first thing you’d probably want to do is check, document and post the modem’s download/upload diagnostics (example) for the following cases:
direct-connected to the provider feed (so with all other coax runs temporarily orphaned);
connected via the amp’s passive output;
connected via an amplified amp output;

p.s. Have you tried a new DOCSIS 3.1 cable gateway? Or even temporarily borrowing (very short-term leasing) a gateway from your provider?

thank you for your prompt answer. I'm going to provide more specific details: 1) The main issue are constant disconnections of the internet service, mainly on day hours. It usually works at night but not all the time. That was the reason why I thought one amp could help. (maybe I am wrong and it is just a technical failure of the service out of my hands, Im not an expert, but here things are very difficult to solve now)

2) Yes, it is a gateway and I use it as a router too and it has one Ethernet connection to provide internet for one DVR placed close to it. I’m not trying to create a MoCA network at home. I didn’t know what MoCA was until I bought the amplifier. My main idea basically was try to amplify the signal so it could mean a more stable internet connection.

3) I haven’t tried yet with another cable modem, or with a Docsis 3.1. Probably it could work? I will attach some pictures about the modem’s download/upload performance

And yes, the amplifier is the commscope CSMAPDU5VPI I wrote it wrong

Title: Will MoCA Adapter Go Above Paid ISP Speed?

Hello!

I’ve read conflicting comments about MoCA adapters being able to go beyond the speed paid for from your ISP. If I have 100 mbps from my ISP, would this adapter bypass this speed and reach near gigabit speeds or is the adapter dependent on my ISP, remaining unchanged?

Thanks for the help!

[Assistant]
MoCA adapters are your internal network. Your internal network will work as fast as MoCA allows. ISP is your external connection. You may get Gigabit speeds on your LAN (between your devices), but will be limited to your ISP speeds for your WAN (Internet access).

Thanks for prompt reply! So, just to make sure I understand what you’re saying, regardless of paying for 100 mbps, if I have a MoCA adapter and coax capable of reaching gigabit speed, so should my internet on my PC?

Your Internet access will be the same 100Mbps. If you access your NAS on your LAN, for example, the local file transfer will go faster.

I have not been able to find out the reason why FIOS' actiontec repeater does not like MM1025s. I have since moved on to replacing it with the FIOS issued router and treating it as a network bridge.

Title: Two LANs with four MoCA

Hi, two ECB7250 connecting two rooms work fine, LAN is 192.168.1.x; I want to use two more ECB7250, each pair connected via splitter, so two MoCA on a splitter in room A, and two MoCA on a splitter in room B.

BUT, each MoCA in room A is connected to a different LAN (192.168.1.x & 192.168.2.x), and MoCA in room B are feeding each one a different switch. In room B, some devices will be on 1.x (first switch) and some on 2.x (second switch). This setup is working erraticaly: sometimes on of the DHCP is giving IPs on the 1.x part, sometimes 2.x; forcing manual IPs isn't working. Some devices are Internet connected, some not.

So I was looking at a way to "separate" the two connections, with MoCA1 in room A communicating with MoCA1 in room B, but with a Netwok Security Setup (same PwD on both, in the D-Ext Band) switched ON on both MoCA1. The other two MoCA are NOT Security Enabled. The two MoCA1 with Security Enabled can't communicate, while the other two are OK. People at SceenBeam can't help me...

Any suggestion how to do it, if it's possible?

Thanks!

[Assistant]
What other signals besides MoCA are present on the coax?

How much throughput are you seeking/needing for each MoCA link?

Vesics said:

Isn’t this a very basic MoCA 2.x feature, at least for one way of accomplishing it — though with the very distasteful side effects of reduced bandwidth? (See section 2.1.1 of the MoCA 2.5 specs)

See below for a related older post; it applies to dual MoCA networks for WAN and LAN but the basics are the same.
krkaufman said:
dual WAN/LAN MoCA networks: MoCA allows for operating two separate MoCA networks within the MoCA Extended Band D frequency range; so you could establish a second MoCA network extending the router LAN over your coax. Drawbacks: Lower speeds, extra MoCA adapter required, and much configuration. The segmentation of the Extended Band D range, combined with lost spectrum required for signal separation, results in the two MoCA 2.5 networks having maximum throughput of 400 and 1200 Mbps:
* Network 1 (D-Low, 1125-1225 MHz): 400 Mbps max
* Network 2 (D-High, 1350-1675 MHz): 1200 Mbps shared max

So you'd need an additional MoCA "LAN" adapter at the router location, connected to the shared coax and a port on the router, and then you'd need to manually configure all the MoCA adapters for their respective WAN or LAN MoCA network.

The additional cost, configuration hassles and reduced throughput make this a less than ideal solution.

Title: Frontier fiber internet - Can I build a Moca LAN

Hello Everyone,

Currently I have Frontier fiber internet, and use coax connection. The ONT box is located outside the house, and the technician put a Frontier FCA251 MoCA adapter in the ONT.

In my study room, coax cable from my wall Jack connect to another Frontier Moca adapter, and then use ethernet cable from the other end of the Moca adapter to router WAN port.

My question is: can I build a Moca LAN? Currently the router is in my study room. I have another 3 rooms, and all of the rooms has pre-wired coax cable. Can I get additional Moca adapter, so I can convert all of the rooms pre-wired coax wiring to ethernet connection, then I can use ethernet cables to connect to my computer ? In another words, I don't need to use wireless connection in other rooms?

Before Frontier, I used Spectrum internet service. I bought Hitron & ScreenBeam Moca adapters in other rooms to build a Moca LAN and there are no problems. However, this time I try to use these 2 adapters but it did not work.

Should I get particular brand adapter?

Thanks in advance for your help.

[Assistant]
very likely. Search this subforum for "FCA251" . There several threads and reference links for how to use .

Good Life said:
My question is: can I build a Moca LAN?
Yes, but because your WAN connection is over MoCA via the FCA251 adapters, you’ll likely need to use FCA251 adapters (with the configuration switch toggled to a compatible setting), rather than retail adapters, to effect two MoCA networks over the same coax. However odd, this setup would require two MoCA adapters at your router location, one bridging your WAN connection from the ONT, and the 2nd bridging your router LAN over your coax.

Can you report back with the current configuration toggle setting for your WAN FCA251 adapters?

FWIW, here’s the operating frequencies for each setting, copied from a goCoax forum thread (which was taken from the FCA251 user guide):

the WF-803FT Quick Start Guide offers the following details on "WAN" and "LAN" operation of the WF-803FT:
WAN (1475-1675 MHz); 2x 100 MHz
LAN (1025-1350 MHz); 3x 100 MHz
FULL (1125-1675 MHz); 5x 100 MHz

So retail adapters *could* be used provided they are configured in sync with (not overlapping) whatever setting is chosen for the FCA251 MoCA WAN link, “LAN” or “WAN.”

edit: p.s. Note that the dual MoCA networks must share the MoCA spectrum, so the throughput for each MoCA 2.5 network is reduced from the theoretical maximum based on how many channels are employed for the link, with each channel offering up to 400 Mbps shared throughput. Basically, you can run 2 MoCA networks, but throughput will align closer to bonded MoCA 2.0 rather than MoCA 2.5.

Good Life said:
My question is: can I build a Moca LAN?
Rather than running two MoCA networks, is there some way that you can isolate the WAN link from the LAN, allowing max throughput for both … and allowing plug-and-play reuse of your existing adapters?

Is there any room that has dual coax runs from the central junction? Could a coax or Ethernet run be added? Do adjacent rooms have coax outlets where you could DIY a coax or Ethernet connection through the shared wall to creatively establish a dual path?

Title: Old antenna coax for MoCA

We have just moved into an old house in the UK which has old antenna coax going around the house and want to use that to feed MoCA signals to save running Ethernet around the place.

My current wife backhaul is not really fit for purpose and it only takes a moment for a device to lose connectivity and cause the network to fail.

The current coax is no longer connected to an antenna as the antenna is long dead (suspect it died in a storm at least 10 years ago). All the coax current goes into a loft into a very old amplified splitter. This is the connected to a cut cable.

As the old coax will never be used for anything, what is the easiest route to get the coax runs working for MoCA? Can I just buy a cheap splitter without a filter making the various coax runs into a virtual single cable? Or is there a specific filter that is recommended? Literally the coax won’t have any deliberate signals injected into it minus the usual interference that can get into any cable.

Any recommendations would be very much appreciated.

Actually whilst it might be rare, the parts are all available on Amazon UK and various other suppliers, so it is definitely here. I’d never use it on Virgin Media cable, but normal antenna coax I would not hesitate.

Those are not usable. they are 50 ohm impedance. MOCA requires 75 ohm. Those are just for line testing.

You will have to check the moca adapter specifications to see if it will pass DC current. If it does not say, for example: DC to 850 MHz pass through, then NO, what you have in mind will not work.

Thanks, so I need TWO MoCa units, right? If so, would it pass PoE?

If not, I guess one other option is to just route the data, and when it comes out as ethernet, put a PoE switch there to give it enough power for the camera.

I would also look at adapters that allow you to use coax for Ethernet connections. MOCA isn't required in your case as you are not sharing the COAX with video.

Never used this type of adapter however they seem to be less expensive than MOCA adapters.

Title: Noob Question About ISP’s and MoCA PoE Bonding Blocks

Hi Everyone,

I’m certainly a noob to all of this but I had a weird conversation with Mediacom today. Earlier this week I canceled my cable and phone service but kept the same plan for internet. Yesterday, I got a text from Mediacom saying that a “field audit appointment” had been scheduled and the times could vary or the dates could change but there was no need for me to be home because all the work would be done outside.

So I went to the side of my house to look in their box (which is inside a privacy fence btw) and the only thing I noticed was a MoCA PoE Bonding Block - https://www.amazon.com/dp/B08DSDG9DZ/?tag=snbforums-20

So that is the only thing I can think of that they would need access to. Is it possible for them to swap that one out with, say, a 2.0 non-bonded as a way to throttle my bandwidth even though I kept the same internet plan or am I just being paranoid? I’m not aware of anything else they would need to do.

Also, sorry if this is the wrong forum. It’s kind of an oddball question.

[Assistant]
They probably just want to ensure the appropriate filter is installed to prevent you from receiving basic cable TV broadcasts as you are no longer subscribing to that service.

Oh. Well I put up an antenna for that. I just never had heard of a “field audit” before and quite frankly don’t trust Mediacom as far as I can throw them. Thank you for the reply though. I’ve taken pics of everything and will just undo and replace any parts they may mess with anyway. That’s assuming they don’t get eaten by one of my four dogs. But I called and warned them.

I don't blame you for not trusting Mediacom, we had a nasty experience with them over a similar situation. When we moved into our house we signed up for just their internet service and used antenna for over the air TV, as that fit our needs just fine. Several YEARS later they conducted a random field audit in our area and threatened to charge us serveral years worth of back charges because their technician who installed the line evidently never connected the appropriate filter to the line. We had never even had the cable connected to a TV!. Fortuntalty we got the matter taken care of but how they went abut the whole situation was ridiculous.

Title: MoCA PoE filter question with external OTA antenna (no cable TV)

Hi there.....I hope someone can help as I have spent hours (days) trying to find an answer to this but to no avail. I currently have a HFC NBN connection which is where the existing ‘pay TV’ or cable network can be used to make the final part of the NBN network connection. In this circumstance an HFC line will be run from the nearest available fibre node, to your premises.

I would like to set up a MoCA Network using my existing coaxial cables. I do not have pay (or cable) TV but I do have an external roof antenna for free to air channels. The lead in cable from the antenna is split across the home into each room via a splitter. In the reading I have done to date, I believe I will need a PoE filter placed at the point-of-entry (PoE) of the cable coming into my home before the NBN NTD modem (DOCSIS 3.1) and another one at the lead in cable from the antenna before the splitter (to prevent broadcasting of MoCA signals). My question is, could the PoE filters instead be placed in every room I have a TV outlet if I am unable to easily access the roof to place it before the splitter? Has anyone had a similar set up? Thanks

[Assistant]
I think you're over thinking things a bit here.

Assuming your OTA feeds into the main splitter where NBN comes in.

NBN <home run / barrel coupler to outlet> cable modem

OTA <filter> main splitter

I setup my own cable connection from the tap to my internal wiring and then just took one of the outlet connectors off the wall and coupled the line to the outlet I use for the CM for a better signal / faster speeds. It's the KISS method of wiring. The closet had a 10 way hub in it but, the DB loss on each connection is more than what I wanted to tolerate for a stronger signal so I eliminated it with the coupler.

There could be issues though if you have too high or low of a signal but, the tech should be able to adjust it when doing the install.

Tech Junky said:
Assuming your OTA feeds into the main splitter where NBN comes in.
Unfortunately it doesn't. The NBN comes from an underground coax lead in, separate to the OTA. This is the reason why I believe a PoE filter is also needed at the antenna cable lead in as I am wanting to use my existing TV points in the wall for the MoCA network. However since I can't access the roof, can I place the filter instead at each tv outlet? Would that prevent the MoCA signal from broadcasting through the antenna? Thanks

The antenna isn't going to broadcast a signal.

https://www.amazon. com/gp/customer-reviews/R3AKBUGFGGTPX5?ASIN=B013J7O3X0 - lengthy / similar setup

So, if you have NBN connect to the one port that you want to use the CM on then leave the rest feeding to the other rooms it shouldn't be an issue as I said above. If you find you have issues with interference on the MOCA side then use a POE filter where the antenna comes into the premises between that and the splitter that breaks out to each room. Think of the POE as a whole home surge protector that you would normally place between the main electrical feed and your breaker box.

Another option would be get a HDHR networked OTA quad tuner and put the antenna directly to that and feed the video signal out to each room over Ethernet or into a PLEX server and feed it by IP to the rest of the house.
I use one of these - https://www.amazon.com/gp/product/B092GCN9NL/?tag=snbforums-20 - this is the latest that includes ATSC3
I used one of these with an older server - https://www.amazon.com/gp/product/B01DZSVLTW/?tag=snbforums-20 - doesn't do ATSC3

I would have just stuck with the PCIE version but, when I went to an ADL build for some reason it killed 50% of the channels that worked fine under the 8700K build just fine. I thought maybe it was the card but, tested w/ a new card in ADL and still had the same issue. The box / card have a downloadable tuner/DVR app but, it's limited in what it can do and Plex makes up for it with a Plex pass and automates scheduling and some other perks.

Just tossing some ideas out there. The filter thing doesn't look like that big of a deal though if you wanted to intercept at each outlet for $7/outlet or simplify things at the source of the antenna coming into the house @ splitter.

Title: MoCA Splitter Setup (IN/OUT) - FTTH

Hi,

I have been using a set of goCoax splitter, POE filter and MoCA devices for some time now. But, I've just changed my ISP from DOCSIS 3.1 to FTTH and I wonder which of the following would be the best way to make the connections to the splitter. I guess any of them will work, but just would like to know which would be the "best practice", if any.

[Assistant]
Seems like a great project for testing and inspecting the MoCA specs to determine which is the most efficient.

I’d recommend also testing configurations tweaked from options 3 & 4, with the splitter right-sized to the number of outputs needed rather than capping unused output ports.

Title: Moca Conversion Old home

Converting older home to Moca using existing coax. Coax into home is now connected directly to cable to living room. Existing old splitter not connected. See photo. Want to use new splitter and move in cable to new one and then connect existing coax cables to basement and downstairs den and upstairs living room too using goCoax Moca 2.5 at each location with modem I’m purchasing (versus renting from Windstream/Kinetic who is discontinuing TV service April 1 but will provide internet). Any issues or concerns to address in setup changes? Or not a DIY project? Image won’t attach but you get the idea. Thanks!

[Assistant]
Not clear to me since i cannot see the house.

Is this going to be internet only or mixed with cable TV from the ISP ?

Is the cable RG59 or RG6 ?

A sketch of the cable layout in the house, location and model # of all devices connected to the coax- splitters, amps, tv boxes, modems, etc. will help us help you. The devil is in the details with moca, but it usually works out if the box if we can get the critical bits right.

Internet to be provided by Windstream/Kinetic (discontinuing TV cable service 4/1). Cable has no identifiers apart from indicated in posted drawing (couplers on coax cable into home connected direct to coax up to main level TV). Sketch attached. Only old splitter - intend to purchase replacement 4 or 5-way splitter, purchase modem compatible w. internet provider service, purchase router as needed, and other moca related items as needed (attachment devices, splitters, etc.). Hope not to have to replace existing coax cables as not sure this would be feasible. Thanks!

Sketch now attached with available information. Windstream/Kinetic discontinuing TV cable 4/1/22 but will provide internet service. Contemplating purchase of goCoax MoCA 2.5 adapters one for each TV location plus replacement 4-way splitter and any other items needed. Hope not to have to replace coax cable as difficult to do so. Need to run one cable from new splitter to TV in basement den area which has drop ceiling. Need to purchase modem compatible with ISP requirements which modem will be on main level by TV. Likely need replacement router as well to be in same location. Terrible existing WiFi reception in basement with cable company suggesting speed increase to 400 or 1 gig as solution with new more costly modem on monthly rental ($30 vs. $10). Not sure increased speed will solve reception issue/range in cinder block basement. Thanks.

Title: Are there powerline adapters that don't depend on mains power?

I'm interested in using powerline networking to replace wifi bridging in a couple of places. However, so far as I can tell all the available products draw power from the mains they're plugged into. That's a showstopper for me, because short outages are common around here, so all my network gear is supported by UPSes. I assume from what I've read that plugging two of these into the battery-powered side of two different UPSes is not gonna work. So ... has anyone heard of units that draw their power from elsewhere, like maybe PoE?

Title: MOCA asymmetric speeds

This has me really puzzled. I have fios with an old Verizon Actiontec MI424WR Rev I router, with ethernet WAN on the ONT and the router. I was purely interested in MOCA to get wired LAN into a couple of rooms in my house that I couldn't easily fish cat5 to. Since all I care about if MOCA 1.1 speeds (I need to stream 4k UHD rips on my NAS), I picked up a pair of additional Rev I routers, and set them up as pure MOCA to ethernet bridges per instructions on the net (basically disabled broadband and wireless). Anyhow, I'm getting 165 - 170 Mbps iperf rates from these "bridges" to my main router, but only half that rate in the opposite direction. The slower rate is associated with many more retries than when I test in the "good" direction. I tried many combinations of interchanging the physical devices, putting in a better splitter, etc, but to no avail. Frustrated, I decided to do an elementary test, so I put one bridge right next to the router and connected the two with a short piece of RG6. Still the same thing! Ironically, given my desire to stream 4k and the fact that my NAS is connected via ethernet to the main router, if the direction in which the slow speed is happening were reversed, I could live with it. Any ideas on how to solve this asymmetric speed issue?

[Assistant]
are these recertified or used units ?

are you observing stuttering on the streaming in the desired direction ?
what iperf command line are you using for each direction test ?
what are the devices being used to test ?
What do you get for test results if you avoid using any of the moca gear between the same two devices ?

Is there a diagnostic page on those modems that gives you the sync rate and power budget/used for each of the nodes ?
if so, what does the table show ?

The primary router was purchased new a decade ago, the two bridge actiontecs are used units. The problem doesn't change shape when moving the actiontecs around.

The devices are various single board computers with gigabit ethernet. Some are running armbian and others are running coreelec. No change if I swap the devices

I'm using iperf3 -s on one end and iperf -c <host> on the other. No difference if I use -R to test the opposite direction or swap server and client commands - its always slow in the same direction

The diagnostic page shows a 250M PHY rate in one direction and 243M in the other. Close enough, no?

Without MOCA gear the speeds are very fast, mostly in the 500Mbps range, and symmetric. I guess the bottleneck in that case is the CPU on the SBCs.

So here's another finding, for kicks I tried a raspberry pi 2 running libreelec on one end. The pi 2 has only 100Mb ethernet, and lo and behold, I get ~94Mbps in the good direction and again roughly half (50-55Mbps) in the bad direction. However, if I use a 64KB tcp window instead of the default, the retries drop to zero and the pi gets 85-90Mpbs in the bad direction too. Unfortunately with the MOCA latency a 64KB window maxes out at 85-90Mbps anyway, so it doesn't help me in my quest to get 150Mbps plus symmetric speeds to stream 4k on the gigabit SBCs. Experimenting with window sizes on the gigabit SBCs hasn't resulted in any improvement

degrub said:
MTU = 1500 across all ?
Correct, no jumbo frames anywhere.

New find, enabling BBR TCP congestion control on the sending side fixes the issue - armbian default is "cubic". Now iperf3 gets up to 150-155Mbps in the slow direction, and file transfers over netcat are correspondingly quick. However, this change is correlated with cifs read speeds slowing down to a crawl (< 1MBps as opposed to 18-19MBps netcat transfers consistent with the improved iperf speed), so for my 4k streaming use case I have more work to do...

I noticed that with default settings, the first couple of iperf transfer windows would give better speeds and then clamp down related to the Cwnd getting smaller. That had me think about congestion control. I'm still puzzled as to what's special about my setup - this is clearly not a common problem - unless windows defaults to BBR or otherwise more MOCA friendly congestion control algorithms.

Title: The Moca adapter is not working , please help

Hello everyone , I didn't know about Moca adapter until a couple days ago. I was and am currently using Powerline network adapter and that is working ok but I want to take it to the next level since I play competitive online games like BF5 so I bought the Actiontech Moca 2.0 ( ECB6200 ) . Spectrum Charter is my ISP and I am paying for 200mb download and 10mb upload speed ( I know the ECB6200 is a bit overkill ) . Anyway I received the adapters yesterday and here is my setup :
My ISP modem(ARRIS TM1602) is connected to the Coax cable directly to the wall and the router (Netgear R7500-100NAS) is connected to the modem via ethernet , I took off the modem and put the Coax splitter instead (the splitter came in the Moca adapter box). then from one end of the splitter to the modem and the other end to the Actiontech Moca adapter coax input . and then from Moca adapter to the router via ethernet . and then of course power cable.
Then in my room where I need wired connection to my PC : I connected the Moca adapter directly to Coax cable on the wall and plugged the power cable and an ethernet cable to my PC from the adapter .
The ethernet light on the Moca adapter is solid green , the power LED is also solid green but the Coax is turned off on both adapters and am not able to connect to internet . Please any idea why it's not working ?

[Assistant]
did you bother to look at the setups others have used here when putting in moca adapters with coax based ISPs ?
For one thing, you need a moca block upstream of the splitter to prevent the signal from going out on the ISPs cable network.

Test the adapters with a 1+ meter RG6 coax. Make sure they sync.
What is the cable in the wall RG6 or RG59 ?
Have you had a digital cable tv box on the connection in that room before ?
Is that cable connected to anything ?

Most coax cable layouts in a house go back to a central distribution amplifier.

You need to find the location where all of your coax meets. Map everything out and make note of any spliiters and amps you find. Upload your drawing of that and then we may be able to help rather than playing a guessing game..

Thank you very much for your reply and sorry I answered late.
I did connect the MOCAs together and they worked so I assume there is no problem with MOCAs.
I don't know what type of cable is inside the walls . How can I figure it out ?
I have never connected anything to the Coax in my room. We have 2 Coax in our house . 1 in the living room which is currently connected to Modem and the other one is in my room which nothing is connected to it.
Sorry I lack knowledge about Coax and wiring , when you say Moca block , you mean Moca filter ? If yes , no I don't have that , should I order one ? any specific model or anything I need to know ?
I also need to find where all the wires connect . I do my research and will update you.
Thank you again

degrub said:

@ari1991, to be clear, this “MoCA block” (aka MoCA filter, PoE filter) needs to be upstream of whatever splitter is connecting the coax runs going to your rooms, not just upstream of the splitter you added to connect the modem and MoCA adapter. The “PoE” MoCA filter would go on the input of the “central distribution amplifier” in @degrub’s later hypothetical.

Yes, you need a “PoE” MoCA filter correctly installed, not necessarily to establish your MoCA network but to secure it.

Simple enough to test... When you can spare Internet connectivity, just take the modem to “your room” and connect it to the wall outlet, and observe whether it’s able to sync with the provider.

ari1991 said:

This is really step #1b in implementing MoCA, the first (1a) simply checking if coax outlets even exist in the targeted rooms.

If/when you find your central junction (fingers crossed), I’d recommend taking and posting pics of what you find, to expedite the assessment. The model numbers of parts matter, as does having a wide enough view to be able to track the connections between components.

Depending on your type of residence, the central junction could be in a bedroom closet, basement, an outside junction box, etc. ... or a central wiring cabinet for a building, inaccessible to you.

Title: Verizon ONT - Working with COAX

I have a 90's era condo, no Ethernet in the walls. The Verizon ONT is in the basement and the COAX is connected thru a splitter to very old (Wireless N) Verizon router up in the living-room and other places.

I wish to replace the router with a newer, non Verizon, AC or AX router. TV is involved, so I think Moca is currently in play, but the Verizon cable box (MOT QIP7232 / A386 / 014 / 500) has an Ethernet connection. If the Cable box can be reconfigured for Ethernet, then I am thinking that I can use a pair of Powerline adapters to connect the new router via "Ethernet" to the Mot?

Access to the ONT is in a corner of the basement. I can easily get to the ONT and connect Ethernet to a router, but the location in the basement is sub-optimal. I would rather it upstairs, but the only existing cable is COAX, and I do not know how or if I can use a COAX from the ONT to a "widget" to the WAN of the router.

Can I use a Pair of Power line adapters, one near the ONT and one central in the dwelling, to pass the WAN? I would like to think its transparent, but I know these devices "play" with the signal and not sure if this is an issue. This method would allow me to optimally place the router. I would still need a wireless repeater to get Ethernet to the Cable box or to a MoCa adapter to the Cable box.

Service is 75\75 and the old N gets about 50 up close. The real issue is at distance in the condo. It's in the low teens in some places.

Looking at a TP-Link One mesh router and powerlines for HW ATM. Not objecting to Moca, but not really used it.

Open to other alternatives and ideas. My experiece is all cable modem.

[Assistant]
The solution that would retain your existing MoCA WAN connection would be following the appropriate DSLReports instructions for converting the old FiOS router to function strictly as a bridge for the WAN connection, or using an Arris MEB1100 at the router location to handle the MoCA WAN link. (I suspect the IP release step for the old FiOS router would remain critical in the MEB1100 alternative.)

You may require an additional MoCA adapter at the router location to support MoCA LAN connections.

Many other possibilities, but keeping it simple for now.

RangerZ said:

Short of installing new cabling, the solution offering the most headroom for growth is installing the new router where it can be Ethernet-connected to the ONT, and then using MoCA (2.5, ideally) for extending the router’s LAN to where needed (and coax connectivity allows).

links:
* MEB1100 (an addl MoCA adapter would be required at the router to service MoCA LAN connections)
* cheap-ish MoCA 2.5
* FiOS router configurations on DSLReports (option 4 would seem to be what you’re looking for, but w an addl MoCA adapter to service MoCA LAN devices)

Title: MoCA latency issue

I've added 5 MoCA adapters *behind* my router using a a PPC-9M-U/U splitter, to leverage the existing coax wiring in the house since WiFi can be spotty in the rooms further away.
The adapters are Actiontec ECB6200 and ECB7250. I reckon that the network will be limited to MoCA 2.0 but that's fine for now.
I have only internet connection coming into the house (Spectrum in NC, 200Mpbs); no cable TV nor phone.

However, I'm experiencing very annoying latency issues. For example, establishing a Remote Desktop session to my remote office computer takes 7-20 seconds, where if I instead used WiFi it will connect within 2-3 seconds consistently. Speed tests show the download bandwidth to be pretty good once the download test starts (200+ Mpbs). However, it can take 30 secs easily to get going (but is much quicker with WiFi).
This latency is also obvious when loading websites that perform several operations to fetch their content (most, nowadays).

Devices connected directly to the router's ethernet ports or to its Wifi do not experience this problem. It's only when the connection crosses the MoCA network.
Strangely, this issue sometimes is much less severe, but is seldom and doesn't stay like that for long. Those times seem be at very off-peak hours, like midnight or later. But not even that is consistent.

I'm wondering if there is an issue in my network setup, or perhaps coexisting the 6200 vs 7250 requires special settings.
When looking at the Phys rates in the 7250, they seem normal from what I've seen in other posts.
I did notice that the three 6200s report a "MoCA password" that is different from the one reported by the two 7250s as "enhanced privacy pwd" but unclear if this is a concern or not.

Attached is a diagram of my network with all the devices included and some screenshots of the devices.

Quick thoughts…
* coax structure seems correct; modem isolated from “MoCA” coax is a good thing (for security and DOCSIS 3.1+ compatibility);
* TX Power numbers don’t look great for a supposed “designed for MoCA” amp.; the spec’d range is -30(great) to +3(maxed-out);
* you’re not amplifying any incoming signal, so the amplifier is sub-optimal; you’d be best served by using a passive MoCA 2.x splitter sized to just what you need, possibly with a MoCA filter for performance improvement. (Though you might try a 4-way splitter sans MoCA filter, with the main node connected via the input port … *if* the Guest Room connection isn’t required.)

edit: p.s. you might try using a MoCA adapter at the central junction to check the stats for a direct connection to each of the remote MoCA adapters, to see if one of the lines is more out of spec than the others.

Of course, you’d also want to confirm that all the adapters are running the latest firmware available.

Thank you for taking the time to look into this.
Yes, all adapters running latest fw.

Your suggestions prompt me to start testing end to end in each segment... and in the process I isolated problems with the Netgear hub in the Porch (hard time getting DHCP to work when directly attached was the first clue, then seeing faster rates when skipping it). Since all MoCA traffic flows thru this to get to the router, it makes sense that it'll affect things. So I replaced that hub and is working much better.

I'm still seeing poor Tx Power numbers though in most of the connectoins reported by the ECS6250s, so I'll test the other hubs next (any tools to stress test a hub? not the first time that I see one misbehave but is very hard to tell because is inconsistent), and more segment checking.

Questions about your suggestions:
- How much of a difference would using a passive splitter make here? Isn't the amplifier without power and with no input signal also acting as a splitter, or do you mean that it has more signal loss? Pondering how worth is to mess with that next.
- Why add a MoCA filter, if no cable/phone signal are incoming to the MoCA network? Future protection?
