orbilogin.com asking me to connect to WiFi?

Using a newly installed RBK50 and 1 satellite. Firmware ver 2.5.2.4

I am using a PC connected via ethernet to the Orbi router.  I am using the web interface orbilogin.com.

I prefer to use this for setting up my devices and want to disable remote management, uPnP etc.

After disabling uPnP, the orbilogin interface is giving me an error "Looks like you’re not connected to your Orbi’s WiFi network. Don’t worry, it happens to the best of us. Try the following steps to get connected..."

Why is the router insisting on using WiFi interface?  How do I get that functionality back to use the browser to access the router interface?

I can't change uPnP back to on (temporarily) either to see if that caused this problem.
