XB7 with MoCA

I have had an XB7 box for about a month and one pod for a few weeks. I have three ActionTec ECB7250 units that were in use for weeks and running fine. One was connected to a three-way BAMF splitter and to the 2.5Gbps Ethernet port on the DB7 (other two splits are to XB7 and the cable tv box). One MoCA unit is in my office with no cable splitter. The other MoCA unit is downstairs at the entertainment center and has a BAMF two-way splitter with one leg going to the MoCA unit and the other to the tv box. I have a Commscope splitter where the line comes into the house; it is powered and has a PoE filter. Everything worked fine until Saturday afternoon.

Our Internet stopped working. A tech came out and said everything was fine on their end; he had no explanation for what changed, but the Internet would work (slowly) if we disconnected the MoCA connected to the XB7. I am unable to turn off the MoCA on the XB7; it was off the only other time I checked it right after initial installation, but it will not turn off now. I also cannot enable WiFi6, but that’s a different story. The secondary MoCA units work with the XB7 initiating the MoCA, but it is much slower than before (2.0 versus 2.5).

Any ideas what happened? I am assuming a firmware update on the XB7 turned on the MoCA, and the box was overwhelmed by all the signals. Should I try a MoCA filter going into the XB7? Would that interfere with my ability to watch DVR shows on the secondary tv box? Is it possible the pod has anything to do with the issues?

I had a SB8200 and Nest WiFi mesh setup before with a streaming service, and I’m considering just going back to that since it was more flexible (I wouldn’t get my full 1.2Gbps down and all ports would be capped at gigabit speeds). WiFi6 won’t turn on in the XB7 settings, so no harm going back to the Nest WiFi.

 I am learning about all of this, so please dumb it down with any explanations. The ActionTec units do not allow any access to look at or change settings.
