X1 not working in a specific room
I have an X1 4K DVR and 3 remote TV boxes. One of the remote boxes stopped being able to receive a signal. I have called in and they have replaced the box twice. All boxes are hardwired to coax cable. The one that stopped working boots up and after the Welcome screen, it says to check the cables to make sure they are tight, etc. Of course all the cables are tight. I suspect something may have happened to the cable going to that box. I would like to switch to a wireless box rather than having to rewire that location.
However, I am using my own router and the cable modem is in Bridge Mode.
Will I be able to use a wireless box such as the Xi6 in that location with my own router?
If not, any other suggestions?
