What if there is no internet connection in the mobile phone wifi exclamation point?

If you use a Huawei mobile phone, you can connect to wifi but can't surf the Internet. You can check it by the following methods:

1. If you are using a home network, it is recommended to connect to other personal hotspots of wifi or mobile phones for testing and troubleshooting:

1. If connecting other WiFi is normal.

(1) Please stay away from the router;

(2) Please check whether the broadband account has expired, restart the router and the mobile phone and try again;

(3) If the router has a black-and-white list, you need to check whether the mac address of the mobile phone is added to the router. If the router does not have a black-and-white list, please turn off the router and restart it.

2. If you connect other WiFi, you can't surf the Internet.

(1) Please reopen the WLAN switch connection attempt;

(2) It is recommended to search and restore the network settings in the settings and restore them according to the screen prompts. (Note: This operation will delete the WLAN and Bluetooth connection records).

Second, if you use a public network:

1. Try to use it in places with little traffic, and make sure that the hotspot can be used normally.

Please confirm whether it is necessary to log in to the website through the browser to register before surfing the Internet.

3. If a single application cannot access the Internet:

Please open the settings, enter traffic management in the search box above, click to enter the traffic management page, click application networking, and check whether individual applications check WLAN permissions. It is recommended to check the WLAN permissions of all applications that need to be used.

If the above method fails to solve the problem, it is recommended to back up the data (third-party applications such as QQ and WeChat need to be backed up separately) and take the purchase voucher to Huawei Customer Service Center for testing.
