Issue running MoCA adapters and having XFINITY TV box disconnect
Hi All,
I’ve been running 2 Screenbeam MoCA 2.5 adaptors on my home network and everything was running fine up until a few weeks ago. One of the TV set top boxes kept disconnecting from the XFINITY network, usually overnight. The box was old so I first swapped it out at the XFINITY store for a new one. Same issue. I then had a tech come out and look at the issue. He first thought that an old amplifier in the basement was the issue. He replaced this with a Commscope CSPM7G passive gateway. When he saw that I was using my own MoCA adaptors, he said that this was “no bueno” due to the fact that all the XFINITY devices now use MoCA to communicate with each other and that I would continue to have problems if I kept using the Screenbeam adaptors. Basically saying that I shouldn’t be using them. Sure enough, the one box keeps disconnecting overnight when the adaptors are running and won’t reconnect unless I unplug them. Is this really the case that I can no longer use my own MoCA adaptors? I experimented with changing the base frequency that the adaptors use and this seemed to help with the set top box disconnect issue but caused big speed degradations/outages over the MoCA/Ethernet setup. As I said, this setup was working fine for about a year. Can anyone provide any guidance on this issue?
Thanks.

If you're using MoCA to stream 4k to 9 different TVs, then yeah, you might start to see an issue, though current MoCA goes to 2.5gbps. Does your MoCA equipment let you select which frequency bands they run on? Moving to a different band and disabling privacy (if it's on) may help to isolate the issue.
You could also try swapping the MoCA adapters that you have to see if things improve. I'm not advocating for abusing Amazon's return policy, but.. they do carry quite a bit of MoCA certified equipment.
The coax in your house doesn't belong to Comcast, it's YOURS. If you want to use MoCA then they can't do anything about it (actually had an argument with a Spectrum tech who didn't let "other equipment" on his coax!). I'm running several MoCA devices and have no issues, so it sounds more like the equipment you're getting is not running current firmware, or Comcast is building equipment that doesn't meet the MoCA standards.
The techs can say "no bueno" all they want (usually because they can't understand what it is), but there's no reason why you can't have 25 different MoCA adapters on your home network, as long as there's enough bandwidth for what they're doing. If they're primarily idle, like the one I use for my desk's ethernet connection, then you shouldn't be having problems and there's something going on with the X1 gear.
Remember that you're almost guaranteed not to get new equipment, but gear that's been refurbished after being used by someone else for years. Keep getting techs out to service the issue until you get someone high enough in the local area that actually knows what they're doing, and not just the punch a hole and insert coax guys. 😉

Thanks for the response and I agree 100% with everything you said. I actually appear to have solved the issue by putting my X1 gateway in bridge mode (which is my preferred setup anyway, but which I had disabled a while back for a different reason). Putting the gateway in bridge mode appears to have removed whatever interference was causing to set top box to disconnect and now everything is humming along.
