Both my nest hub and mini (older models) will not connect to my Google Wifi. I suspect it is because they are 2.4 ghz I know that the Google mesh is dual band and should accept both types of device but this appears to not be the case. I have attached them to the base wifi (Virgin Media) with out any problems but would prefer them to be attached to Google. Any suggestions?
What specifically happens when you try to connect them? Any error messages or do they just not connect?
Try these steps:
If none of the steps above help, factory reset the device and then retry setup. Note that this will clear your data from the device and can't be undone. You may also want to try setup using a different phone or tablet if you have one, just to test.
