I have two Nest Routers and no matter what I do Google Home app (iOS) displays Wifi as Offline for both of them, but it's not? Touching their icon displays them as Online and connected. What's up with this?
I'm not using a VPN, not using Private Relay, and have turned IPv6 off and on several times.
Known issue, the Google Nest Wifi folks are aware, but no words of when we can expect a fix. You could try to simply refresh the Google Home home screen by pull down to refresh. Could also be worth trying to factory reset ( https://support.google.com/googlenest/answer/6246619?hl=en ) then set up again ( https://support.google.com/googlenest/answer/9548301?hl=en ), reusing your existing network name (SSID) and password so wireless devices reconnects automagically.
Sorry that the resets aren't working for you. In addition to the resets, have you tried uninstalling and reinstalling the Home app? Your settings will be saved, and as soon as you log into the app after installing again, they'll be restored. If you haven't tried that, give a try and see if that helps.
Thanks for letting me know you've taken those steps as well. This is something I'll take to an internal team and will return with more info as soon as I can. If you notice any changes or anything that affects your network performance, please let me know. I'll return with more info soon.
