Can you use the Orbi 6 with Verizon Home wi-fi?

What is orbi 6? (model)

You can connect a orbi to a verizon home wifi. It does cause a double nat which most devices are fine with. 

A double nat happens when you cascade more than 1 router.

If it does cause issues, there's fixes for it. 
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.
