We have been using our Arris modem for over two years works great. We recently switched to tmobile from Xfinity. We disconnect the service. It's been just a month and we switched back because tmobile was dropping and services spotty.
We are now with Xfinity. They say everything thing is set up.on their end. Gave them the serial number and Mac address. While I can see the modem and connect, it won't connect to the internet. It does not seem to be communicating with Xfinity. Does anyone have any ideas o what I can try?
