I was able to setup my Orbi RBR750 with the Orbi app on my Android phone I configured the router in AP mode with a fixed IP address. When I use the app it occationally connects and when it does it doesn't last long. then won't reconnect. I have Verizon FIOS internet and use Opnsense as my internet facing router. If needed I can run a packet trace from Opnsense filtering on the RBR750's IP address.
