The router is online，but the device cannot be connected?
Firstly, you need to make sure that you are connected to a 2.4Ghz network. If you are not sure what your network is ( you can also check "How to split the WI-Fi SSID" into 2.4G and 5G subnets in the FAQ ". The 2.4Ghz extended network is split ), it is recommended that you use the AP mode ( the AP mode will automatically select the 2.4Ghz network for connection ), and then add it again. If you can connect to the device but have problems, you can provide us with the device ID ( 1. Open the app; 2. Click your device to enter the device details page; 3. Click the icon in the upper right corner to enter the "More" page; 4. Click "Device information" to view the device ID ). Thank you for your understanding and support!
