What modem do you have?
You say you're using DSL cable from modem to router? I question this a bit as the R6900 doesn't have any dsl ports.
Do you mean you're using an ethernet cable between the 2?

U r probably right. There's 4 ports in the infinitum modem, out, which I have a cable in port 3, running to the r6900.
I setup, plugged and played everything years ago.
Just stopped today.

What optimum modem is it?
If it has 4x ports, it could a modem/router combo device and causing 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.
