Nest cameras and doorbells is offline or unavailable

The checks in more detail

turn off other devices on wifi, check the power, check the app version, restart the modem and router, check whether the camera feels too warm or too cold, move or disable network extenders and check your router settings. Google adds that the main router often gives a better connection than an extender, so a camera that joins a poor extender can drop, and turning extenders off tests that. Wait a few minutes after each step. The guide stresses you must be able to reach the camera to fix it. A restart keeps settings and reconnects to the same wifi.

As a last step, factory reset, which deletes video history and settings and needs a fresh setup. If the app says the camera is connected to another account, use Google's help codes guide. Note when the camera dropped and what was happening then, such as a heavy download, a new device or bad weather, since the pattern usually points at the cause faster than any setting. If the camera drops only at night, check for a scheduled router restart or a change in a neighboring network.

Photograph the app message and the camera's light when you contact support, since the pair usually names the state within a minute. When several cameras drop together, the router or the provider is the cause, and when only one drops, the camera's position or power is, so count how many are affected before you change anything. Google notes that gaps in video history are normal when a camera saw no activity, so compare the gap with the offline notice time before concluding the camera was down, and use the app's status light description to match what you see at the device with what the app reports.
