C7000v2 and Xfinity Internet Issues- Forced factory reset

I think I solved the problem, at least I haven't had this happen in a couple of days. 

I live in an condo with many wifi networks, and the majority of them are on channel 1 for regular wifi and channel 149 for 5G. I used Acrylic Wifi to see at the networks so I could manually choose a channel that no one else was using. When the router was crashing, it would choose channels 1 and 149, even though it was supposed to automatically find an empty channel. 

Having a unique channel seems to have done the trick.
