I have a Nest Wifi router and 2 points that have been working without an issue since I purchased them in October 2020. Today the points were showing as not connected to the router (lights were orange) and I have tried various troubleshooting steps without success and have run out of ideas.
As before, the Nest router is wired to my ISP router and the points are placed in adjacent rooms.
So far I have:
*In all of these scenarios I get to the stage where the points ping (indicating they have connected) but when the connection is completing they fail and display slightly different error messages.
I have local network access enabled on my phone, and have toggled it on/off, but the message still appears for on of my points when attempting to add it back on to the mesh.
The other odd thing is that both points are now visible as separate wifi connections on my laptop - i.e. Hall Wifi.E70.ybc,
I had your same issue for weeks on end. Decided to factory reset router again but you'll notice that after reset it has an automated prompt for adding points and I used that to add 2 of my 3 points successfully. I accidentally closed the automated prompt before finishing the adding of 3rd point. Attempted to use plus sign to add Device. Sure enough all steps complete with sound until final step where it shows "Could not communicate with your nest wifi point" . Makes no sense at all and I'm too lazy to initiate factory reset again just to add a single point. I have samsung flip 3. Same issue with setup via iPhone. Just about unforgivable , google, and I say shame on you for not keeping customers informed of this issue.
