If you have a 1st gen Nest Protect
If you change your Wi-Fi network’s name (SSID), password, or other settings, or if you get a new Wi-Fi router, you’ll need to remove your Protect from the Nest app, and then set up your Protect in the app again.
Note: If you have a 2nd gen Nest Protect, you can simply update Protect's Wi-Fi settings in the Nest app.
