This is a long story without all the details.
I have the latest XB6 modem and one X1 DVR. Both of them are two month old. In the morning when I turn on one of my three TV's which use the small cable boxes I get error RDK-03004. The TV connected to the X1 DVR works fine. I can reboot/refresh the DVR (which will work) and all three cable boxes but I still get the error. Unplugging them and rebooting doesn't help. Phone support told me to do the same thing but the problem persisted.
The only thing that restores the small cable box signals from the DVR is to unplug and reboot the cable modem.
Xfinity sent a technician to my home who arrived just as I got an error code. He rebooted all the equipment but it didn't help. I disconnected the cable modem and the signal was restored to all the TV's. He replaced some connectors, a switch, and a power source, rebooted the hardware and everything worked fine.
This morning the problem returned. I rebooted the cable modem and the TV signal was fine. I don't want another technician who can't fix the problem to come to my home. There is obviously something amiss with the XB6 modem that interferes with the TV signal. The modem does have the most recent firmware.
Hopefully someone from Comcast will see this and offere some help. Thanks in advance.
Thanks for replying.
Yes there is a white light on the back.
open a browser on a device that's connected to your internet connection and enter 10.0.0.1 in the browser

go to connection
go to moca and click disable and save
You may have to restart your X1 boxes after
MoCa can’t be unchecked. Bridge mode is disabled. If I enable it can I uncheck MoCa? It says if I enable it will disable router functionality of gateway and turn off wi-if....sure if you want to continue?
