Settings just returns to main screen.

Installed new Nest thermostat 3rd generation.  Will not find any wifi networks.  I have unplugged and plugged in my router.  All other devices on my wifi are fine.

I also tried pulling out the thermostat and resetting it  by holding it in until it resets. Both seemed to work okay but still no wifi networks detected.

Also, when I am on the main screen on the thermostat, anything I click (eg Settings) just returns back to the main screen.

Hello @IndianRoad 

Thanks for reaching out to our Nest Community. I'm happy to help you with this new Nest Thermostat and the connection with your network.

I really understand your current situation. Let me lend you a hand to find a solution. 
When is the first installation with our Nest Thermostat, we suggest first charging the thermostat display with the USB port located on the back for the display. 

After a full charge, your Nest Thermostat can connect normally with the WiFi network. 

Feel free to keep us posting about your situation. I'll find a solution for you.

Best regards,
Douglas.
