Why can't my mobile phone connect to wifi?

If you are using a vivo phone, it is recommended to operate as follows:

1. Check whether the WiFi password is correct.

It is suggested that when entering the password, click the "eye icon" to display the password to ensure it is correct.

2. reconnect to WiFi

Please go to Settings-WLAN, click on the WiFi you need to connect, and then click "Forgot Network/Forgot Password" to reconnect.

3. Check whether the WiFi network is normal.

Please compare whether other mobile phones are normally connected to the same WiFi, and confirm whether it is WiFi or mobile phone. If it is due to WiFi, please restart the wireless router check. At the same time, you can enter the router management interface to see if there are any special functions, such as limiting the number of connections, MAC binding, online time management and so on.

4. Reset network settings

Resetting network settings will delete the connection records of WLAN, mobile data network, Bluetooth and other networks. You can enter Settings-System Management-Backup and Reset-Reset Network Settings-Reset Settings-Follow the prompts (you need to select the corresponding SIM card for dual cards).

Note: Enter the cloud service-data synchronization-turn on WLAN, Bluetooth, etc. Synchronize data to the cloud service. Go to Cloud Service-Device Cloud Backup-Backup Data Type-Open System Data-Return to the previous page-Back up immediately and back up some system setting data.

5. Restore all settings (please do this when you can't see the Reset Network Settings menu)

You can enter Settings-System Management/More Settings-Backup and Reset/Restore Factory Settings-Restore All Settings-Restore, Restore Settings Options. This operation will not delete files or software, but will cancel the password and restore all settings, including the set wallpaper, unlocking method, WiFi, default opening program, etc.

Backup can be made before operation: enter cloud service-device cloud backup-backup data type-system data-return-immediately back up some system settings and desktop layout that can be backed up; Cloud service-data synchronization-turn on WLAN and Bluetooth to synchronize data to cloud service.

6. After operating the above methods, if the problem still exists, please go to the local vivo customer service center for testing, enter the vivo official website-My service network, select provinces and cities to inquire about the address and contact information of the local service center, or click the webpage link to search for the address of the service center.
