Pixelation Issues after New Modem Install?

We recently installed a new model/router after have multiple drops per day making it impossible to work from home. Looks like the same X1 router but supposedly an new model. We have Gig speed.

Since swapping out this modem on Saturday, we have experienced pixelation issues on TV. Could this possibly be related to the cable modem?

I so hope this goes away. We are exhausted from troubleshooting the internet drops constantly through the day (Ethernet or WiFi) and now this which I’m sure is a pain to troubleshoot.
