Check the Nest service and the app
ReversibleGoogle's help page for a Protect that disconnects or is offline starts with the Nest service status, then the latest app version.
Update the Wi-Fi settings on the Protect
ReversibleIf you changed the network name or password, the Protect must be told the new ones in the Nest app. Restart the router by unplugging it for about 30 seconds.
Press the button and listen
ReversiblePress the Nest Protect button once and listen to the spoken message. A Protect that has lost its Wi-Fi connection says so, and it keeps sensing smoke and carbon monoxide without Wi-Fi, so it is safe in the meantime but will not send alerts to your phone until it reconnects.
Check what changed on the network
ReversibleIf the router's name or password was changed, or the Protect was moved to a far room, the alarm may be looking for a network that is no longer there. Remove the alarm in the Home app and add it again, using the 2.4 gigahertz band, which is the one the alarm uses.
