Changed internet providers.
Changed internet providers, from Comcast to ATT. How do i connect my R7800 to the new internet address?
My router is connect in my office, my ISP modem (ATT/u-VERSE) is on the other side of my home. If I understand your direction, should I power them both off for 1 minute?
How can I tell which version of firmware I am using?
As noted, I have an ATT/U-verse modem. Model is BGW210-700
BTW, everything worked great with Comcast and not sure why the difficulty with ATT
Sure would appreciate a reply from e38 superuser, to my prior notes. Thank you!!
att uses a modem/router combo device versus comcast is a modem only device.
Start with factory resetting your r7800. Then during install, you'll need to change your settings to fix the double nat from the 2 routers.
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.
