Finally took the step and returned the cable boxes (1 wired and 1 Wifi). Also returned Modem. Bought Netgear Nighthawk C7800. Finally got it working with computers, phones, Ring, Nest, Rainbird and the biggest pain was the security camera. Unfortunately after I bought the Netgear I did not know the Xfpods were not compatible. The good news is the Netgear is so much more powerful it delivers to areas where pods were previously necessary.
Some odds and ends. Problems with my Roku TV. Without the cable box from Xfinity it no longer receives Xfinity channels. The App will not work. The irony is the Xfinity stream continues to work on computers and iPad. Quick solution was to 1 - read up on Google and 2 - set up mirroring and broadcast Xfinity to Roku from computer. Ut oh. Not allowed. I have no idea why.
Now I read that I can replace my Xfinity X1 Box also. It looks like Tivo is an option. Anyone have any input on good or bad with Tivo/Xfinity? Thanks in advance.
