RBR750 DHCP
I have an Orbi RBR760 connected to my cable modem, also Netgear. My network Gateway / DHCP is 10.0.0.x. Works as advertised, most of the time. However, I noticed a number of connected devices that...
What actual netgear modem is it?
Usually if the router switches off the default ip address, the modem its connected to isn't just a modem, its a modem/router combo device.
Its why model numbers help.
If it is indeed a modem/router combo device, 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. Probably not the option I'd use.
3. Put the Netgear router into access point mode. This disables its routing functions. Wifi/ethernet still works but it does disable some features.

I'd probably go with option 1 or 3.
