If the mobile phone has been connected to WiFi, but the client does not recognize the WiFi signal during pairing, you can do as follows:
1. Find the client in the mobile phone permissions, and make sure that the "network permissions" and "location permissions" of the client are turned on
(iOS phones need to select "Precise Location" for the location permission)
2. If you do not know where the mobile phone permissions are set, you can directly uninstall the client and download the client again;
3. After reinstalling the client, the basic permissions that require authorization will pop up. It is recommended to authorize directly;
