Here are some troubleshooting steps to try if your Nest Protect won't connect to Wi-Fi, your Nest Protect is not connecting to the Nest app, or you received an error, such as P008 or P013.
If one of these error codes appears, select it to view specific troubleshooting steps.
If one of these errors appears or if there's no error at all, read below for some steps to help you add your Nest Protect to the Nest app.
1. Check the Nest service status
To check the status of the Nest service, go to Nest System Status. While the service is down, you may also get a message "The Nest service can't be reached right now" in the Nest app.
If the Nest service is down, wait for the Nest service to resume, then check if you can add your Protect to the Nest app.
2. Make sure the app version is up to date
3. Make sure your home Wi-Fi is working
- If you've recently updated your Wi-Fi network's name (SSID), password, or other settings, you may have to update your Protect's Wi-Fi settings in the Nest app.
- If you haven't changed any of these settings, check that your Wi-Fi network works for other devices.
- If other devices are connected to Wi-Fi but your Protect can't connect, move on to step 4 in this article.
- If other devices are disconnected from Wi-Fi, move on to step 5 in this article.
Tip: If you're using your cellphone to check, make sure it's connected to the same Wi-Fi network as your Protect and cellular data is turned off. To help make sure cellular data is off, turn on Airplane mode and then turn on Wi-Fi.
4. Move closer to the router
You may have to move your Nest Protects and mobile device closer to your router as you try to add your Nest Protects to the Nest app.
5. Restart the router
Restart your router to reset your internet connection. You should also restart any Wi-Fi range extenders or repeaters.
Note: Every router is different. You may need to consult your router's user manual for specific instructions on how to restart your router.
- Unplug your modem and router power cords. You may have a combination modem/router, or they may be separate devices. All the lights on your modem and router should be off.
- Wait for 30 seconds, then plug your modem and router back in.
- Your modem and router will restart. Wait a couple of minutes or until you get steady power and connection lights. There may also be a quickly flashing data light.
- Once your router finishes restarting, test the Wi-Fi connection with another device.
- If other devices reconnect but not your Protect, move on to the next step in this article.
- If none of your devices reconnect, contact your internet service provider to check the service status in your area.
6. Reset Nest Protect and restart mobile device
7. Check the settings on your Wi-Fi router or access point
Check your router's manual for instructions to find and change the following settings if needed:
Enable IPv6 or Multicast
If you want to connect a Nest Protect, make sure that your router supports IPv6.
When adding additional Nest devices, make sure your router supports multicast and that it's on. Nest devices use multicast to communicate and set up connections with other Nest products.
Check if your router has wireless isolation settings turned on. This will prevent devices on your network from connecting to other devices in your home. Nest products talk to each other during pairing, setup, and during daily use, so they may not work properly with these settings turned on.
Turn on 2.4GHz
Make sure your router is broadcasting 2.4GHz. Nest Protect can't connect to a 5GHz network. If you have a dual band router that broadcasts both 2.4GHz and 5GHz bands, give them different names so that you can connect your Protect to the 2.4GHz network.
Parental controls or firewall securityHigh firewall security or parental controls can block communication with Nest servers. You can temporarily lower these settings while you connect your Protect to the network, then change the settings back once it's connected.
