2. Check whether the network signal used is stable. If it is unstable, you can change the location or time period and try again after the network signal is stable.

3. If the network is displayed when the network signal is stable, it may be that the software limits the permission to connect to the network. I suggest you go to Manager I- Traffic Monitoring-Network Management of this model, and find the permission of software setting to connect data and WIFI network.

4. If the networking permission is turned on and such problems still occur, you can use other networking software to see if similar problems will occur;

5. You can update and optimize the software version information, or try to uninstall and reinstall.
