My 3rd generation Nest learning thermostat has worked for over a year with no problems. But a few days ago it started showing W5 error code, it can't see my router and I repeatedly tried all the troubleshooting steps, restarted my router, entered username and password manually, factory reset the thermostat, but without success. Please help. Thank you.
Thanks for answering @davidking.
@Logger, sorry to hear about what's going on with your Nest thermostat. I appreciate that you've already went through these troubleshooting steps, too. Could you provide a photo of your thermostat's display showing the w5 code? Also, where and when was this bought as well as what country are you in?
Thank you for your answer.
Yes, the problem still exists. And I need help.
I took a photo of the display with W5 error. https://drive.google.com/drive/u/0/?usp=sheets_web&fd=true
The thermostat was bought last winter on the Internet.
I am in Norway now.
I hope you can help solve the problem)
