Add an already configured EX7000 to the Nighthawk App

Hello,

I've manually via the webpage configured my EX7000 and it's working great, however when trying to add it to the Nighthawk app it wants me to connect to SSID "NETGEAR_EXT". That doesn't seem to show up, just the networks that I have configured do. I'm also on one of those networks with the phone I have the app on, but it seems that I have to be connected to the SSID above.

So my question is: is there a way to add an already configured extender to the Nighthawk app without resetting the router and starting over?

Would appreciate any input, could be a simple mistake on my part.

Thanks!
