I learned about MOCA from your channel and now I have 4 adapters, and I am slowly converting all my friends as well. It's really a great product.

Lon, maybe I missed it, but you didn't tell folks how to setup MoCA adapters when you have one coax line in a room connecting to an Internet modem. The way is to attach the incoming coax to the MoCA adapter's "Coax In" port. The "TV/STB out" port should go to the cable modem. Then the Ethernet port of the cable modem goes to the input of a router. One of the router ethernet outputs goes into the MoCA adapter. In another room (or rooms) connect another MoCA adapter to the Coax port there. Connect the MoCA adapter's ethernet port in that room(s) to either a switch or directly to a device. Back in the room where the Internet modem is, you can connect the other ports of the router to devices in that room

I know it seems confusing, but if you draw out what I described, you'll see how it works.

My moca came in today. Set it up in under 10 minutes. Now have reliable WiFi (already had a second router) upstairs for the first time. Thanks, Lon

I like these kind of videos. I had an about 15 minute ride home, and I was able to just put this on in my truck (phone face down on the other seat of course) and listen while driving home. And I got to learn something too.

It would be nice to add PoE+ into the MOCA specification. This will remove the need for a power brick on the receiving end to power the MOCA device and the PoE end device such as an access point or security camera. That's 2 power bricks unneeded! There are PoE Ethernet over Coax products out there, but these products are not smart enough to avoid cable TV signals. MOCA has this avoidance. This is why I only use MOCA bridging devices because they don't block cable TV signals. Is this PoE feature planned for MOCA 3.0?

MOCA requires the following for performance:

You need to use RG6 cable swept to 3ghz, ideally RG6 Quad. Never ever buy that copper clad steel garbage and ensure it is a 100% ofc copper wire. If ypu have any RG59 cable ot needs to be ripped out and replaced.

RG11 (with copper conductors) should be used for very long runs, say over 100ft out to a shed, pole barn etc.

You need MOCA compliant splitters and distribution amplifiers. Most splitters are not swept to 3ghz, and will drop the frequencies used by MOCA
MOCA is between 1125 and 1625 mhz. Most splitters and distribution amps are 5-1000mhz. Usually if you have Sattelite splitters you will not have an issue.

Purchase MOCA 2.5 adapters. They will get gigabit ethernet performance on RG6 quad copper wire and have additional security feature such as MoCA protected setup and advanced encryption. Cureently only GoCoax sella these to the public. Mototola, ZyXel and ActionTec only sell MoCa 2.0 bridges.

For a future Q &A: One area that you have not covered in using MoCA adapters is their use with over the air (OTA) TV antenna (ATSC). Is this possible? Are the frequencies used for USA ATSC different than those used for MoCA? Also, you covered the specifications for splitters to use in a coax network with MoCA, could you also give the specifications for using amplifiers in these networks or if these do not work at all. I setup my grandma's house with a OTA TV antenna then later hooked this to my mom and dad's house next door over a RG6 ~500' quad shielded cable, so that they could use the same TV antenna. Cellphone reception at my parents place is bad. I have setup a cellphone booster at my grandmother's house. My parents have a hotspot for internet, but it is hit and miss with reception. My idea is to move the hotspot to my grandmother's house for better reception using the cellphone booster, then sent the internet over the coax to my parent's house.

Would placing the filter at the coax in of the MoCA, or at the coax in of the modem (device feed from the MoCA) accomplish the same task as placing the filter on the wall coax inlet?

Do I really need a moca POE filter if I have Verizon Fios G3100 Gateway moca enabled router. I have the highest speed provided by verizon 960/860 Mbps. I'm getting conflicting responses that FIOS is digital and doesn't need the POE filter.

Thank you for this talk. I did not find the answer to my question which is this: I have four MoCA 2.5 adapters (2 from ActionTec (ECB7250) and 2 from Kiwee Broadband, both using the Maxlinear MxL3710 chipset), connected directly by a coaxial cable, without any splitters, and without any potentially interfering signal such as cable TV etc. The MoCA adapters' web interface confirms a 3700Mbps-ish PHY rate between the two adapters, but ttcp, nuttcp and iperf all report only 125Mbps:110Mbps computer to computer (interestingly, the speed is consistently about 10% lower in one direction than the other). That's irrespective of which 2 of the 4 adapters I use on either end (both Kiwee, both ActionTec, one of one kind, one of the other, or if I swap the adapters around). If I connect the same two computers with a Cat. 6 cable (using the same 1000BaseT Ethernet ports), ttcp, nuttcp iperf give me 940-1023Mbps:940-1023Mbps - so yes, both computers have 1000BaseT ports and they can deliver near-1Gbps performance - interestingly, the throughput in the case of a direct Ethernet connection is symmetric, there isn't the 10% differential. I am using the correct (MoCA, not TV) port on each of the MoCA adapters. I've swapped the coaxial cable, tried 3 different coaxial cables (first I tried the long whole-house coax cable of unknown length, then a spare 6ft cable I had, then finally the about 1ft coaxial cable supplied with the adapter itself), all with the same results. I've tried swapping the Ethernet cables on both ends - I started with two 2 metre Cat. 6 cables, then swapped then with two 25cm long Cat. 8 cables. I've checked all the coaxial cable connectors and they are tight. I've tried reducing TX power and Beacon Power Level (normally I have them set to 10, but I reduced them all the way down in steps of 1). I spoke to ActionTec and Kiwee tech support and they could not identify the problem. They advised me to check what could be causing EMC interference but we could not identify anything in the environment that could be causing a lot of EMC. Also I tried the setup with both computers in the same room, with a 1ft coax. cable between the two MoCA adapters and two 25cm Cat. 8 cables either end, so there wasn't a lot of cable exposed to EMC, and I tried this setup in two different rooms. I have all adapters configured to use D-Low, D-High and D-Ext bands, with LOF set to 1150. At the suggestion of tech support (I can't remember whether ActionTec or Kiwee) I tried switching them both to a different band once - I can't remember any more which band, though, but I switched them both to the same band. It made no difference. The band settings are not documented so I don't really know what to try. The available controls are: D-Ext, D-Low, D-High, E, F-SAT, F-CBL, H, Custom; LOF (a number), Scan Mask, Scan Offset, Pri Ch Above Mask, Pri Ch Below Mask, but I don't know what these do (presumably bit masks saying which frequency bands should be permitted and which one not).

In all these permutations of setups, the throughput via MoCA is consistently about 125Mbps:110Mbps, but via a direct Ethernet cable connection, 0%-6% below 1Gbps:1Gbps. And in each case, the adapters' web interfaces suggest that MoCA to MoCA PHY rate is about 3.7Gbps. Why is the end-to-end performance so poor?

Understand where to put the filter now. But what about in a room different than the room where the modem/router is? Just a coax cable outlet only?

1:32 really? everything I found on MoCA compatibility with satellite tv said they interfere (note we have DVB-S2)

I got two of actiontec ecb6200 with ARRIS SURFboard SB8200 DOCs 3.1 cable modem and when I plug the moca adaptors they don't seem to be getting the coax connection in my house. I'd seen some videos that put the moca POE filter on the cable modem because it's a 3.1 setup. Will they work without POE or do I need the POE filter in order for it to work. The current setup is wall cable to coax in, TV out to cable modem, router lan to moca adaptor --> second room --> wall to coax in, moca lan to PC on the other room. The coax lights won't come up but my internet works.. I'm guessing is the POE adaptor but maybe I'm just missing something.

I may have missed it in the video, but it is my understanding that a POE Moca filter is not needed when the signal is delivered to one's home by a fibre optic cable. Is that correct? (I really enjoy your videos.)

I used a pair of these to connect my router to a wi-fi extender. It makes a huge difference. I have not run any scientific tests, but it seems nearly as fast as ethernet.

Hi, non tech guy here. I have fiber now, but old coax cables in the entire house, so I got moca to have stronger internet on my pc than wifi (works great).
I have a question about the PoE Filter, in this case, where there is just on coax cable from one moca device to the other, is it still a problem of "leaking" signal? or can it still go outside of my home? Since all coax cables are in my apartment and none leaves, just the fiber.

Great video! Is there a certain brand or type of MoCA filter I should buy? Thanks!

Also look at the cable and connector, if you see any of the shield touching the center wire, that is a short and it will not work. Cut that off and redo it. Depending on the quality of the connector, you might be able to pull it off easily, there is your bad connection right there most likely! You will know a good connector when you see it, it will be securely crimped on and even be a bit of a pain to work with on some TVs where the connector is close to the side of it (of all places).

How does this work if my isp is cable internet and they send the internet and tv through the same coax line ??

I recently had fiber internet setup in my residence at one end of the home(my office). They were not able to install the fiber connection in the middle of the home due to complications with the homes ceiling. An ethernet cable comes out of the small powered modem on the wall which is right next to the Cable company's jack. My question is, can I reverse the MoCA adapter using it's ethernet LAN connection as an "In from source". Then use the coax "Out" of the adapter as the connection to coax jack/cabling in my home? Eventually I want to find the cable leading to the center of the home/where my entertainment center is and "bridge" the two coax cables. Is this do-able?
