lost wifi on thermostat and forgot pin to reset

[NHgerry]

I came back home from being away for a few days and my thermostat had no wifi connection. When trying to correct I discovered I had forgotten the PIN. Without wifi on the thermostat I cannot change the PIN from the app.  Help!

If you've tried the usual things like restarting your thermostat and router and it still won't reconnect to Wifi, then follow these steps:

1. Connect the Nest Thermostat display via USB to a computer.
   
   
2. Verify that the Nest Thermostat mounts (appears as an attached drive icon).

• If the Nest drive will not mount: Restart the thermostat and the computer.
• If the Nest drive still won't mount: Connect another device to the cable to see if it appears as an installed device.
• If it doesn't appear, use a different cable/port/computer.

If the Nest drive is successfully showing up on your computer, can you see a technicalinfo.PLIST file? If you get this far let me know and I'll ask a community specialist to assist with next steps, as these can't be shared publicly in the community.

thanks David.

I contacted Nest tech support and they walked me through the process. It worked and I am now up and running.

Thanks to all who helped,
