Correct WiFi password suddenly no longer accepted on some devices?

[miwero]

Just had Fidium Fiber hooked up, and a new modem installed. Plugged the Google mesh wifi in, and everything worked perfectly for a few days. Now we are noticing some devices can no longer connect- the Brother printer, now my iMac.

I keep getting "incorrect password" screens, even if I shared the password from the Home app- the password is correct. Curiously, my guest network works fine! I am hesitant to take everything down and reset, as I have many devices using this network, and it's worked perfectly for a long time. My Mac's network panel says "WiFI has no IP address".

When you got your new "Fidium Fiber", did you configure your new router/modem with the same network name (SSID) and password used on your old router/modem?

If not, then you'll probably have to do a factory reset on your Google Nest devices and then reinstall them, since Google Nest does not provide a way to update Wi-Fi settings on many Google Nest devices.
