How to update Wi-Fi settings on Nest Secure including Nest Guard and Nest Detect

On April 8, 2024, Nest will no longer support Nest Secure. It will not be accessible in the Nest app and will no longer connect to the internet. You will not be able to use the Nest app to check the status of your Nest Secure, control your Nest Secure devices, or receive notifications from your alarm system. 

For more information, go to this Community Forum post.

If you change your router’s settings, Wi-Fi password, or install a new router, you’ll need to update the Wi-Fi information on your Google Nest Guard to make sure it can still connect to internet.

Note: Your Guard connects directly to your Wi-Fi network, but your Detects don’t. Instead, they get their internet connection through your Guard. When you update the Wi-Fi information on your Guard, your Detects should also come back online.

Try using the same network name and password

The simplest fix for most Nest products is to update your home network so that the network name (SSID) and password are the same as before. This will usually work even if you’ve purchased a new Wi-Fi router as long as the manufacturer settings are the same.

If this doesn’t work, or you want to keep your new network name or password, you’ll need to update the Wi-Fi details on  your Nest Guard.

You can update Wi-Fi information for Google Nest Secure with the app on a phone or tablet that has Bluetooth.

  1. Go to the same room as your Nest Guard, so that your phone can communicate directly with it over Bluetooth.
  2. On the app home screen, tap Settings .
  3. Select Home info then Home Wi-Fi help.
  4. Now tap your Guard.
  5. Tap Start.
  6. Follow the on-screen instructions.
