Asus zenwifi xt9 to Fios ONT

I currently use a Google wifi puck connected to Fios ONT (I don't have Fios TV). I'd like to replace the Google wifi pucks with two Asus units.

When I plug the main Asus in, the light is blue and I can see the network and connect to to it, but I can't set it up through the ASUS app and I get no internet. If it isn't obvious, I really don't know what I'm doing and any help would be appreciated.

Thanks
