Troubleshooting connecting your Nest thermostat to a Wi-Fi network:

1. Make sure your home Wi-Fi is working Since your Nest thermostat uses your home Wi-Fi network, check that you can get online with another device in your home. You can visit nest.com to check if your connection is working. If you’re using a cell phone, make sure you don’t use cellular data to test your connection.

Tip: To help make sure you’re not using cellular data, turn on Airplane mode and then turn on Wi-Fi.

If you can’t connect, try using a different device to double check. If you can’t connect with any device, contact your internet service provider to check the service status in your area.

2. Restart your Nest thermostat Restarting your thermostat will refresh your connection.

1. Press the thermostat ring to bring up the Quick View menu.
2. Turn the ring to Settings and press to select.
3. Choose Reset > Restart.
4. Turn the ring until Ok appears on the screen and press to restart.

After your thermostat has finished restarting, follow these steps to try to connect your thermostat to your home Wi-Fi network. You may need to enter your password again.

1. Press the ring to bring up the Quick View menu.
2. Turn the ring to Settings and press to select.
3. Choose Network and select your network name.
4. If prompted, enter your Wi-Fi password.
5. Select Done to connect your Nest thermostat.

3. Restart your router Restarting your router will reset your internet connection. You should also restart any Wi-Fi range extenders or repeaters.

Here’s how to restart your router:

1. Unplug your modem and router power cords. You may have a combination modem/router, or they may be separate devices. All the lights on your modem and router should be off.
2. Wait for 30 seconds, then plug your modem and router back in.
3. Your modem and router will restart. Wait a couple of minutes or until you see steady power and connection lights. You may also see a quickly flashing data light.

Note: Every router is different. You may need to consult your router’s user manual for specific instructions on how to restart your router.

4. Check for interference Try turning off any devices that operate on a 2.4 GHz frequency, then try connecting your thermostat again. Here are some devices that might cause problems:

  • Cordless phones
  • Baby monitors
  • Microwaves
  • Bluetooth devices
  • Wireless video equipment
5. Check the settings on your Wi-Fi router or access point Incompatible settings on your home’s Wi-Fi router or access point can cause your thermostat to be unable to connect to Wi-Fi.

Parental controls or firewall security

High firewall security or parental controls can block the Nest thermostat from connecting to Wi-Fi.

Refer to your Wi-Fi router or access point’s documentation to see how you can exempt the Nest thermostat from these restrictions.

If you still can’t connect your thermostat after checking your parental controls or lowering your firewall, make sure you’re using settings that allow your thermostat to connect to your home Wi-Fi.

6. Check the incompatible list If after you check your router’s settings your Nest thermostat still wont connect to your home Wi-Fi network, check that your router or modem is not on the incompatible list.

Note: Even if your router is on the incompatible list, some incompatibility problems can be resolved by changing your router settings or by updating firmware.
