1. Make sure the device is powered on and turned on.

2. Ensure that the device is in the state of the network to be deployed (flashing/slow flashing), and the status of the indicator is the same as that of the APP.

3. Make sure that the device, mobile phone, and router are close to each other.

4. Make sure that the network where the device is located is smooth and stable. Check the method: put the mobile phone or Ipad on the same network and put it on the side of the device, try to open the webpage.

5. Make sure the router password entered is correct. Pay attention to whether there are spaces before and after the password.

6. Make sure to add the device using the 2.4G Wi-Fi band. Wi-Fi needs to be turned on and cannot be set to hidden. Check whether 2.4G and 5G are shared as one SSID. It is recommended to change to a different SSID.

7. Make sure that the encryption mode of the router is set to WPA2-PSK, the authentication type is AES, or both are set to automatic. Wireless mode cannot be 11n only.

8. If the number of devices connected to the router reaches the upper limit, you can try to disable the Wi-Fi function of a device to reconfigure the channel.

9. If the router enables wireless MAC address filtering, try moving the device out of the router's MAC filtering list to ensure that the router is not blocking the device from networking.

10. Make sure that the router has the DHCP service enabled. If it is not enabled, the address will be occupied.

11. If it still doesn't work, it may be that the compatibility between the router and the device is not good. It is recommended that you replace the router and try again.
