Everything was fine. I had some router problems and reset it to factory settings, which changed the SSID of my Wifi network. I successfully connected to the new default SSID. Then I reconfigured my router and restored the SSID and password to the previous settings. I have tried multiple times to reconnect the Nest thermostat to that Wifi network, which it had previously connected to without problems. It keeps saying that the password is incorrect, but I have checked carefully what I'm entering, and it is correct. So, following instructions, I removed the thermostat from the Google Home app. I tried to add it back with the QR code. My remote sensor was added but not the thermostat. I have tried two or three times, but the thermostat is not added. I have two Wifi networks (5G and 2.2G); I have tried both, but I get incorrect password on both. I really need to speak to someone on the phone, but the support number no longer works. Many of the instructions for both the phone and the thermostat are confusing because they often do not match what I see on my iPhone or on the thermostat. It isn't a big deal right now since I have heating off until the fall and have no A/C, but I'd like to get it working normally again. I'm using WPA3-Personal (recommended by Apple) for authentication on the router. I'm tired of the cumbersome process of entering the network password on the Nest and then seeing it fail.
