How Nest cameras and Nest Hello automatically reconnect to your Wi-Fi network

Google Nest cameras and Google Nest Hello remember your Wi-Fi network information, so if it becomes disconnected, gets unplugged, or loses power, it will automatically reconnect to your Wi-Fi network.

Things like network congestion, power outages and internet service provider issues can cause your devices, including Nest cameras and Nest Hello, to temporarily disconnect from your Wi-Fi network. You may see it listed as OFFLINE on the Nest app home screen, and you may also receive a notification that your camera or doorbell has become disconnected. As long as your camera or doorbell is getting power, it will continually search for your Wi-Fi network. Once it’s able to find your Wi-Fi network again, it will automatically reconnect itself using the stored network name and password.

In some cases, you may need to manually restart your Wi-Fi network for your camera and other Wi-Fi devices to reconnect. Most routers just need to be unplugged for 30 seconds and plugged back in to restart. Refer to your router’s documentation for specific instructions.

What happens to video history when Wi-Fi disconnects

Your camera or doorbell has internal video memory that can store about five minutes worth of video at 720p resolution. If you have a Google Nest Aware subscription and your camera or doorbell is disconnected from Wi-Fi for a short time, but still powered on, it will store video until it can reconnect to Wi-Fi.  When it does, the camera will attempt to upload the last five minutes of video to your video history while still capturing and saving new footage.

What to do if you change your Wi-Fi password or get a new router

If you change the password for your router, your camera will lose its Wi-Fi connection and then attempt to reconnect but fail. See the article below for more details.
