RBR20 connecting to new wifi
Changed from ATT Uverse to Xfinity and can't get ORBI RBR20 to connect to the network. Have tried just using reset but device has 'issues connecting'. Shouldn't have to do a new setup, I don't think,...

att uses their own gateway that has an integrated router with it. it causes a double nat.
A double nat happens when you cascade more than 1 router.

Fixes? There’s 3 options but only use 1.
1. Put the modem/gateway in modem only/pass through mode. This disables its routing functions.
2. Leave the modem/gateway in router mode but put the Netgears IP address into its DMZ. This forwards the data to the netgear. You can either leave the modem/gateway’s wireless enabled or disabled. Just make sure its using a different wifi channel to prevent interference
3. Put the Netgear into access point mode. This disables its routing functions. Wifi/ethernet still works but it does disable some features.
