W5 error problem, have tried all the troubleshooting suggestions but nothing works.

My Nest Thermostat has the reported "w5 error" and cannot connect to WiFi. It does not even detect the WiFi. Have tried all suggestions (restart and reset both the router and Nest Thermostat) and still won’t connect to WiFi. None of my other nest thermostats have issues connecting. Please help.

If you continue to see the W5 help code after restarting your thermostat, the best thing to do is contact support. Make sure you have the help code and your thermostat’s serial number ready to go before your call. To find your thermostat’s serial number, pull the display off the base and flip it over. The serial number is above the QR code on the back of the display. When you reach an agent, be sure to let them know you've already tried restarting your thermostat.

Thank you David. I followed up on that. The customer service team did some troubleshooting and decided that the thermostat has to be replaced. They will send the new device shortly.
