We'll need to take a look at the following from the modem...

Please post a copy and paste of the modems connection status and event log page.

What Firmware version is currently loaded?

 

What channel configurations are currently set on the router?  
Any Wifi Neighbors near by? If so, how many?

 

Also if you can get the modem factory reset and setup from scratch fully, would be good to have a saved backup configuration file. Saves time if a FR is needed. https://kb.netgear.com/24231/How-do-I-back-up-the-router-configuration-settings-on-my-Nighthawk-router

    I did some more digging and found a solution; sharing, in case anyone else has this problem.

     

    I read reports from some others that there have been instances where the CAX80, upon being reset following an internet outage, reset the Wifi SSID to "Broadcom."  I was able to access the router remotely using the Nighthawk app, which would show a HomeAssistant server (hard-wired) as connected, but no Wifi devices.  I checked, and it showed that the SSID's had been reset to "Broadcom."  I was able, using the Nighthawk app, to reset the Wifi SSID and passwords to what they should be; and following a reset, the Wifi devices were able to connect once again.

    While this workaround does solve the problem, it's still a bug (something for Netgear to look into) that the restoration of an internet outage can cause the SSID to change to "Broadcom."
