I have been using AT&T for 3 years with my google wifi nest. I have decided to switch to Spectrum. They are coming today to change my service. How do I connect my nest (I have 6) to the new network? I am my families IT... I can't remember how I set it up in the first place, it has been so long.
Google Nest does not make it easy to change Wi-Fi settings. That's why they say: "The simplest fix for most Nest products is to update your home network so that the network name (SSID) and password are the same as before. This will usually work even if you’ve purchased a new Wi-Fi router as long as the manufacturer settings are the same." (https://support.google.com/googlenest/answer/9223711?hl=en) That's what we did when we got a new router/modem about a year ago.
If you have to change the SSID and password, you should review Google Nest's recommendations before removing the old Wi-Fi router/modem, because for some devices they recommend removing the device from the Google Nest app or Google Home app first.
