I just upgraded my Xfinity internet and both my Rokus will no longer connect to my Xfinity streaming nor any other apps (Netflix, prime, etc). I have a Roku premiere and it is updated to the latest software update 9.4.0. I have only had both of my premiere devices for about a year, a little less. I don't know what to do. Xfinity said it is not their problem and I can not speak to anyone live to troubleshoot the Roku. Can someone please advise?
