Television (wired receiver) glitches when other television (wireless receiver) is turned on.

Hello @rcarmv,

We're here to help. Could you please elaborate on the glitches that you're seeing and/or hearing when you turn on TV-B? Is it pixelation, or intermittent signal? Is it only the video that is affected or is the sound affected as well?

We look forward to your response!

The picture and sound are both affected equally.  The picture seizes up for a short period of time ranging from a fraction of a second to perhaps 3 seconds at the most.  The glitching is random but occurs perhaps every 2-3 seconds on average.  The glitching is somewhat worse when trying to view HD channels (compared with non-HD channels).  Perhaps every few hours the signal is lost completely for a minute or two.

TV-A is on a coaxial connection from the wall.

I have tried moving the receivers around.  Same problem regardless of what receiver is in the location of TV-A.

I have not yet tried replacing the piece of coaxial cable.  I guess I figured that since the system in the location of TV-A is fine unless TV-B is turned on, that the wiring is not the problem.

I cannot connect to the gateway 192.168.1.254     My internet service is not through AT and T.

Performed factory reboot as you suggested with no improvement.  I have also replaced all the receivers and the residential gateway in the last two weeks.

I agree with you that this is probably a bandwidth issue, but what can be done about that?
