I just got the Mango router but I doesn’t not detect xfinitywifi hotspot. I scan other networks around me and my other devices can connect to the hotspot.
I tried changing the ssid channel to 13, connected through SSH with no luck.
About a year or so ago I believe xfinity switched all their xfinitywifi access points to the 5 GHz wifi band. I upgraded to a 5 GHz compatible GL-iNET router and am back online now.
