Nest Learning 3rd Gen thermostat suddenly offline and failed to connect to Wi-Fi network

[AlanCine]

Hi, my Nest 3rd Gen thermostat has gone offline with a W5 error. It had no issues since I installed it five months ago.
 It lost connection for two days, and I can’t get it to connect at all despite following all of the troubleshooting instructions. I have finally done a factory reset, but it can’t find any WiFi network despite all other connected devices. There is no issue with WiFi or broadband.

Best,

I hope things will work out.

I'm located in North America, and the link to the form you've sent is not working!
