If you change your Wi-Fi settings or install a new router, make sure the Wi-Fi information in the Google Home or Nest app is updated. Otherwise, your Nest camera or doorbell can't connect to the internet. Use the app you set up your camera or doorbell with.
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 each of your Nest products.
In the Home app, Wi-Fi information for cameras and doorbells can't be updated, so you'll need to factory reset your device and set it up again in the app. In most cases, you'll remove your device from the app and add it back.
Important: Make sure to save any important video clips before you start. When you remove your device from the app and factory reset it, you'll lose your video history.
Tip: If you set up your camera in the Home app (and it isn't compatible with the Nest app) and you want to keep your video history, don't remove your device from the app. Factory reset your device manually and set it up in the Home app as a new device. You'll have two versions of your device in the Home app, one with older video, and one with new video.
