12/27/2023 0 Comments Moca connection xfinityCoax is run to most every room in the house (large house, ~ 4000sf on 2 floors) with a 225ft leg underground to my father-in-law's apartment. Comcast service enters the basement and is connected to a distribution amp through a POE MoCA filter. The technician told me that it was unlikely that I would be able to continue to use the Actiontec solution, which has been rock-solid for the last 3+ years and quite fast enough for my purposes.Ī bit of background on the cable topology. This was apparently being soaked up somehow by my coax and pushed to Comcast's neighborhood infrastructure. He saw both bursty electrical noise and AM/FM band interference. He used a signal/spectrum analyzer to look at all of my coax connections, and came to the conclusion that the noise was generated by one or more of my four Actiontec ECB6200 MoCA2 adapters, which provide connectivity to equipment at both ends of my house PLUS a garage/apartment outbuilding that my father-in-law lives in. It didn't completely fix the problem for them, but it helped. When the technician arrived, he started off by saying that my problem was most likely triggered by noise generated by my coax infrastructure Comcast discovered the noise on the local "leg" a while back and apparently installed a low-pass filter of some sort that stripped out the upper channels that would normally have been available to my modem for uplink bonding. Similar timeouts appeared in the cable modem's log. That seemed to improve reliability 32 channels down bonded, but only 4 out of 8 up. In the meantime, I took the proactive measure of replacing the SB6141 modem with a NetGear CM1000v2. They agreed to roll a truck which came today. Repeated calls to Comcast eventually resulted in a theory (by a Comcast rep) that it was either a Comcast external cabling issue or my modem. The status page at showed 8 downstream channels bonded and 1 upstream bonded, with the other 3 timing out. My modem (until this morning a Motorola SB6141) would lose sync and cycle through downlink/uplink/transport (or whatever the "globe" icon means) multiple times and eventually connect. I asked Comcast to check things on their end and they did not see any problems in my area. Mostly it would work fine during the day, but early morning and late afternoon would see some interruptions. I've had some issues with internet connectivity over the last 3 weeks. Comcast no like, install other filter make cable modem sad. Tldr Actiontec ECB6200s make noise on neighborhood cable, POE filter no help.
