If device setup fails, check the following:
1. Confirm that the device is one of our products. Other brands may use separate platforms and may not be supported.
2. Check that the device has power and is turned on.
3. Put the device into setup mode according to its product manual.
4. On iOS 14, grant the app local network and wireless data permissions.
5. If the app says the device is linked to another account, follow the on-screen instructions to unlink it before adding it again.
6. Make sure the network signal is strong and stable.
7. If the router has too many connected devices, disconnect another device from Wi-Fi and try again.
8. Check the Wi-Fi password, extra spaces, and letter case.
9. Check the router security settings for WPA2-PSK with AES, or the corresponding automatic settings. Do not restrict wireless mode to 11n only.
10. If MAC address filtering is on, make sure it does not block this device, or turn filtering off.
11. Enable the router DHCP service so the device can obtain an IP address.
12. If setup still fails, send support a video of the setup process for further investigation.
