Scenario 1. The mobile phone hotspot cannot be searched by other devices:
Check whether the AP band is set to 2.4GHz or 5GHz. If the AP band is set to 5GHz manually, some devices may not be able to search for the WLAN hotspot.
If other devices do not support 5GHz band WLAN, they cannot search for this hotspot at all. You can replace other devices that support 5GHz band to search for connected mobile phone hotspots. Or set the AP band to the 2.4GHz band, so that devices that support the 2.4GHz band and 5GHz band can be searched and used. (If the mobile phone only supports WLAN in the 2.4GHz band, the hotspot is established in the 2.4GHz band. You can query whether dual-band WLAN is supported by the parameter table.)
Scenario 2. The hotspot can be found but cannot be connected:
Ensure that the WLAN function is enabled on the mobile device that you want to connect to, and that the hotspot name and password are correct on the WLAN list.
Ensure that the number of devices connected to the mobile hotspot does not exceed the specified value. For example, if the maximum number of connections is set to eight users, eight devices cannot be connected.
Try modifying the connected devices in the Manage Devices list to any device.
Check the hotspot Settings in the following way: Go to the Settings screen, click more (Wireless and Network) > Mobile network sharing (Mobile hotspot) > Portable WLAN hotspot to view the hotspot name, password, and number of devices allowed to connect.
Scenario 3. The hotspot will automatically shut down after being used for a period of time:
Please confirm whether to set a single traffic limit. For example, if the mobile data usage upper limit is set, the mobile hotspot will automatically shut down when the usage upper limit is reached. This is a normal phenomenon, if you need to continue to use can modify the traffic limit limit. You are advised to set a single traffic limit during daily usage to prevent the traffic from exceeding the package limit due to updates and downloads after other devices connect to the hotspot.
Please confirm whether you have used similar file transfer software such as face to face fast transmission in QQ. This kind of function is through the mobile phone WLAN function for file and data transfer. During the transfer process, the WLAN and hotspot functions of the mobile phone are automatically enabled or disabled. As a result, the hotspot functions of the mobile phone are automatically disabled or abnormal. Uninstall such applications and try to use the hotspot function of the mobile phone to check whether the functions are normal.
If the hotspot function still cannot be used normally after following the preceding steps, back up important data of the phone and try to restore the factory Settings. If the factory recovery still cannot be resolved, please go to the local network for testing.
