I am having issues adding a new wifi point to my existing google wifi mesh. I have not been able to test my internet connection, mesh connection, or anything else since November of 2021. I have read many threads previously but nothing seems to work to fix this problem.
Are you using the Google Home app?
Make sure you're logged in with the same Google account in the Google Home app as the old Google Wifi app.
Worst case: Factory reset all your Google Wifi points (https://support.google.com/googlenest/answer/6246619?hl=en) and set up your network from scratch in the Google Home app (https://support.google.com/googlenest/answer/9548301?hl=en). If you use the same network name (SSID) and password as your existing network, all devices should reconnect automatically.
