Can't add a Nest Hub to Google Mesh - Turn Off AP Isolation

[CoachDave]

I have a 3 point Nest Mesh network. I am trying to add a 1st gen Google Nest Display, (which was previously on the wifi, but I moved it) using the Google home ap.

I get the following message.

Your Nest Hub was setup successfully but can't be found blah blah blah.

Turn Off AP isolation.

How do you do that on this Google Nest Mesh?

Google Nest Help does not seem to have any documentation on AP isolation on Google Wi-Fi, but I found this post; I don't know if it is accurate or not, since we don't have Google Wi-Fi:

Thank you for the reply.  The link wasn't really my issue, but it did get me to another link which was more applicable.  I tried following that link, but so far I haven't quite gotten it to work.  If I do, I'll post the results, but at this point I may just trash the old hub, because it would be cheaper to just buy a new one than to hassle adding back the old one.

I puzzled over this AP isolation issue and wondered why there isn't more on it, and I think the reason is that Google uses a QR code now to add new devices to an existing network.  That QR code must somehow handle the AP isolation issue as I have added new devices to my network over time.  Currently I have 21 devices on my network, but adding this "new" Hub ("new" because I did a factory reset on it) revealed this AP isolation issue.

Hi there,
 

CoachDave, that certainly hasn't been easy for you. The AP isolation message has also something to do with the “Guest WiFi network”. Did you set up a guest network in the Google Home app? If yes, disable it for the meantime to be sure that Google Nest Hub will connect to the main WiFi network. If not, check if Google Nest Hub was paused.

Thanks for the help here, MpIsCustomer.
