A “w5 error” is affecting the working of Nest thermostats and preventing them from connecting to Wi-Fi. Google has identified the issue and has stated that it’s a problem with the device’s Wi-Fi chip. The company has claimed that it will issue replacement devices if the problem continues to persist and doesn’t get resolved with troubleshooting.
Due to the w5 error, Nest has been unable to establish a remote connection with their devices since November of last year. Users reported that devices affected by the error can’t detect Wi-Fi networks at all and none of the factory resetting works to fix the issue. Some users also reported that the issue started after installing a software update.
Google responded by issuing the following statement:
“A very small number of Nest thermostat users are experiencing a known issue with the Wi-Fi chip that causes remote connectivity issues. This does not affect the thermostat’s ability to control the customer’s heating and cooling system in the home, but does impact the user’s ability to manage the thermostat remotely. If a user sees this error and it can’t be resolved through troubleshooting, they are prompted to contact customer support for assistance and will be issued a replacement device.”
