Orbi router no internet
I've got Orbi router RBR50 and satellite units. From my Orbi app, it shows internet is off-line... but my Mac connected through the cable from the router is no problem accessing internet at all, just...
the modem is :
TELEPERMIT
Smart Modem VRV9517
it's from the internet provider.
I don't think it's related to the modem, as I has been using it with the Orbi for nearly 2 years and it's all good until last week. although the app say there is no internet but all wire connected device from Orbi router, like iMac, TV are able to connect to internet, it also able to do the internet speed test from the Orbi app with good speed.
Its because that modem isn't just a modem. Its a modem/router combo device and 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.
