C7000V2 reset disrupted wireless connectivity for some devices

[RD1111]

This router had been working wirelessly with no issues in a home environment with two PCs, two iPads, two Android phones, and an HP printer.  Yesterday, the router was briefly disconnected from power and coax.  After being reconnected back to the same power and coax connections, the two PCs and the printer came back as expected.  The iPads and phones will no longer connect automatically to the network and, when I try to manually join the network, instead of seeing the expected sign in page, a Netgear genie admin account password reset page is displayed.  I have tried resetting the modem, but same problems persist.   Any suggestions for fixing this issue?

Try disabling WiFI Private IP address feature on your iPhones and iPads:

Thanks for suggestion.  Unfortunately, disabling private wi-fi address had no effect.  Same issue persists.

Try a Forget this Network on the Apple devices then try to re-connect.

What channels do you have set on the modem? 

Is Smart Connect enabled on the modem? 

As a quick test, set WPA security on wifi to NONE. Do these devices connect then? Re-enabled WPA2 and AES after testing this.
