Google’s Nest thermostats make it easy to control the temperature of your home remotely, but that all relies on a wireless connection. Over the past few months, some Nest owners have encountered a “w5” error with wi-fi which cuts off all remote connections.
The error, which has been popping up since November on ongoing forum threads, won’t pull the plug on actual control over your thermostat, but just the ability to control it from a smartphone or smart speaker. While it’s nice to know this issue won’t entirely wreck your A/C, it does essentially break the biggest selling point of the product.
For some users, this problem can be fixed through a standard reset or other troubleshooting measures. For others, the known hardware with the internal Wi-Fi chip requires a full hardware replacement — which Google will provide for free after a customer contacts support. Google explained to The Verge:
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.
Reports of this issue have come up most in recent weeks than previously, suggesting that a recent Nest update could have caused the “w5” error for more users. Android Police noted some cases where the issue appeared “immediately” after an update.
