A W5 help code means that your thermostat can’t connect to Wi-Fi. Follow the steps below to troubleshoot this code.
1. Check for a W5 message
Note: You can only check for a W5 message on your thermostat. The code doesn’t appear in the app.
When the error first occurs, your thermostat should display a message that says it’s unable to connect to Wi-Fi. The message ends with "nest.com/w5".
If you dismissed the W5 message, you can check your thermostat’s Network menu to confirm that a W5 code has occurred.

- Select Settings
.
- Turn the ring until Network appears. You may get one of these messages:
- “Error - nest.com/w5.” This is the W5 code.
- The name of your Wi-Fi network. This is not a W5 code.
- “Not connected.” This is not a W5 code.
