I just upgraded from Xfinity to AT&T fiber. With Xfinity, I had a surfboard modem that was wired to my Orbi RB753S and all works fine. AT&T installed their wireless gateway, which is also fine. But I need to fix the dead spots in my house. Can I connect the Orbi to the AT&T gateway as if it was my old surfboard modem, i.e. ethernet cable to the "internet" port on the orbi? Should that work, plug and play? Thanks
but you'll need (want? ) to fix the double nat it causes.
A double nat happens when you cascade more than 1 router. https://kb.netgear.com/30186/What-is-Double-NAT 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. ATT gateways haven't always worked that well in passthrough mode. 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. https://kb.netgear.com/26765/Which-features-are-disabled-on-my-NETGEAR-router-when-it-is-set-to-AP-M...

Thanks. I still have the two orbi satellites I plan to use. Does that make any option better than the others? Is any option preferred from a performance standpoint or should they all work about the same (assuming the gateway works ok in passthrough mode)?
