Pixelization since new router box installed

An Xfinity tech installed an upgraded router on 10/23/2025.  Since then my TV picture has frequent and intermittent pixelization issues.  Voice and Internet are working fine.  All cables have been checked and several restarts performed

I’m really sorry you’re experiencing that it’s frustrating when everything seems to be working except the TV picture, especially after a recent equipment upgrade. It sounds like you’ve already done all the right things by checking the cables and restarting the system multiple times. The timing with the new router installation makes it understandable to suspect a connection or signal issue related to that change. Since it's been a few days since you last posted, are you still having trouble with the TV picture, if so please don't hesitate to reach back out.-Richard

Yesterday, 11/3/2025, I contacted Xfinity support.  An Xfinity tech spent about 30 minutes examining my installation and reloaded everything from his end.  Pixelization is better, but not gone.  I tried another restart today and will wait to see.  I ordered a new MoCA splitter and new coax patch cables to see if that will help.  Parts should be delivered on 11/5/2025.  Of course the pixel problem was worse during the Monday night football game.

user_cyc5o2 From experience this can be a channel issue too. I tend to hear about pixel issues during NFL games. Please let us know if you see a difference after you receive your new cables.

Replacing the splitter seems to have solved the problem - the new router was apparently stepping on the video signal.  A thread on Reddit pointed me at this solution.
