Phone (Android Pixel 4a) only device unable to access Internet via Nighthawk C7000v2

Not an issue with the phone as it connected to the previous router which was Netgear. The issue is inside the Netgear Nighthawk, I'm assuming created by the mid-set-up crash that seeming put the device being used to do the set up into a do-loop validation state where it is stuck. I had to restart the Nighthawk set up from my laptop and was able to complete on the second effort, but the phone is still stuck in the middle of the first setup. My guess is that I need to purge the Nighthawk from it's "memory" of previous devices, probably previous MAC addresses that it's seen. But I can't find how to do that.
