Are you doing what following instructions tell you to when setting it up?
Where do you live? Reason I ask is that Nest Wifi won't work in all countries, like China for instance where Google is blocked.
Where did you buy the unit? Reason I ask is that wifi (the standard/ protocol) have different restrictions in different parts of the world. For instance, US units would not be able to pair up with EU units, at least not in my experience, because they default to a different 5GHz channel than EU units do. So make sure your unit(s) is made for your region.
I’m having the same issue. I’m in Texas, bought through Amazon and although the google WiFi is found through google home, when I press next I get a half spinning wheel and then a blank white screen. Can you assist? I removed the google home app and re downloaded it, unplugged the WiFi for 5 min and have the same issue
What modem, and is it in bridge mode? What IP does a computer get if you plug the ethernet cable straight from the modem to it? Have you tried with the Google Home app from a different device? Have you tried resetting the Google Wifi (https://support.google.com/googlenest/answer/6246619?hl=en)?
I just wanted to follow up real fast to see if you were able to get this worked out or to see if you still needed help. If you are still struggling with this, let me know and I will be happy to continue to help. Also, if you are still having setup issues, would you mind telling me what platform you're using to set up the devices (iOS or Android)?
