RBR50 Can't check for firmware updates
My RBR50 no longer seems to be able to check for firmware updates and says "Service Unreachable": Any ideas on how to fix this?

What modem/gateway are you connected to?
- pbarhamFeb 22, 2021Apprentice
Standard Xfinity Xfi supplied cable modem ... (with its WiFi access point functionality turned off). That seems to be working just fine for everything else.

Turning off the wifi doesn't turn off the router functions of the xfinity equipment. It puts you in a double nat.
