When I had an Xfinity Modem installed, the tech told me I couldn't use the 192.168.1.1 address on my router (can't remember why), but I did change it to something that I cannot remember. For SOME TIME, everything has been working great: cable enters room, connects to Xfinity Modem. Ethernet from Modem to PC. Ethernet from Modem to AC-68R LAN Port. Dual Band throughout the house.
Then I made a disastrous mistake trying to use Xfinity Modem's admin page to convert it to Full Bridge Mode...
AC-68R IP Address
