RouterEntry · Sources checked · How we write our guides
This guide concerns Nest Wifi Pro. Google says it cannot join a mesh made from older Nest Wifi or Google Wifi units. Confirm Pro before following an expansion or setup guide.
Open Google Nest Wifi Pro settings
Open the Google Home app and select the home containing your Nest Wifi Pro network. Google’s setup route uses the app and a Google account; a generic browser login button is not the documented setup route.
Which password does this screen need?
Use the Google account with access to that home. The network’s Wi-Fi password connects your devices. A device setup code serves onboarding, rather than replacing either of those passwords.
Wi-Fi settings
In Google Home, open Home → Wifi → Network settings and select the existing password. Enter the replacement and save. Reconnect devices that used the old key.
Adding another mesh unit
Expand a Nest Wifi Pro mesh with another Nest Wifi Pro unit. Google’s app setup supports scanning the device QR code or entering its setup code when scanning is unavailable. Check compatibility before erasing an older Nest Wifi network.
If you cannot sign in
If you cannot sign in, follow Google Account recovery and answer its ownership checks; reset the account password when prompted. If sign-in works but the network is missing, check the selected account and home. Ask an administrator of that Google Home to check your membership and permissions. A factory reset does not recover an account or grant membership in someone else’s home.
If the screen asks for your Google account, use account recovery in the official app or website. Confirm that account manages this network. Resetting the equipment is not a way to recover an online account.

If internet access fails too
Compare another device on the same network. One device failing and every device failing need different checks. Note any equipment error and consult your provider when the shared connection remains unavailable.
