What should I do if I display the exclamation point with wifi?

If you use a vivo phone, there will be an exclamation mark next to the WiFi signal icon, indicating that the WiFi network to which the device is currently connected is unavailable. It is recommended that the device be closer to the WiFi signal source or try connecting to other WiFi networks. If this phenomenon exists in all WiFi, please refer to the following troubleshooting methods for connecting WiFi normally but unable to access the Internet.

The phone is normally connected to WiFi but cannot access the Internet:

1, check the phone settings.

Go to Settings-WLAN to see if you have successfully connected to WiFi.

Go to Settings-Other Networks and Connections-Private DNS to see if private DNS is set. If so, it is recommended to set the private DNS to off and try again.

Go to Settings-Security/Security and Privacy-More Security Settings-Trusted Credentials-System-Please turn on all options.

Step 2 check WiFi

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. Some public ***WiFi needs to be authenticated by the browser before surfing the Internet.

3, check the networking permissions

Please enter I Manager-Traffic Management/Traffic Monitoring-Networking Management-WLAN-Open Software Networking Permission.

4. Investigate environmental causes

If the mobile phone is far away from the router, although there is a WiFi signal, it may actually be unable to access the Internet. Suggest adjusting the distance between the phone and the router and try again.

5. Reset network settings

Do a good job of backing up data such as WiFi, enter Settings-System Management-Backup and Reset-Reset Network Settings-Reset Settings, and then use it to view.

Note: Resetting the network settings will clear the connection records such as WLAN, mobile data network and Bluetooth; Dual cards need to select the corresponding SIM card.

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

Go to Settings-System Management/More Settings-Backup and Reset-Restore all settings, and then follow the on-screen instructions.

* Note: This operation will not delete the software or files, but only reset all setting options; For data security, important data can be backed up before operation.

7, service center testing

If the above methods fail to solve the problem, please back up the mobile phone data in advance and take the mobile phone and purchase certificate to vivo customer service center for testing.

(Address of customer service center: Go to vivo official website /vivo Mall APP-My-Service outlets/After-sales outlets-select provinces and cities to inquire about the address of customer service center).
