Slave DVR boxes not working
Yesterday our slave DVR boxes (we have 3) stopped working and began bringing up a red error screen. The main DVR box and our smaller non DVR boxes are all working fine. Xfinity WiFi working fine
We have reset the main box and all DVR boxes, reset our modem and router (not Comcast devices), all without any success. I tried to unplug all devices, then powered up router and modem, then main box, then slave boxes as well.
I've read about but don't fully understand MOCA issues and neighbors. My children say there was a Xfinity service tech working on the large green box in our yard the day this issue started. I'm assuming this was for a neighbor.
Xfinity is now recommending a tech come in our home. Due to Coronavirus risks, I don't want that.
I would greatly appreciate any help here.
