I replaced my cable modem today and now my Xfinity stream for Roku and iOS no longer recognize they are on a Comcast network. The WiFi network was restarted after the modem replacement. All other internet is working fine.
There have been other forums which are now locked where @ComcastElla & @ComcastChe have fixed this exact issue but apparently the phone reps don’t know how to fix this or end up making matters worse.
already working? it can take 24 hours for the new modem to update all the databases. you can check by calling 800-Comcast and select billing. ask the agent to verify the new modem's HFC MAC address is the one currently listed for your account (and that no other modem is on the account).
