The mobile phone is not connected to wifi, and the mobile phone is not connected to wifi

If you use a vivo mobile phone, you can't connect to wifi, and the troubleshooting method is as follows:

1. Confirm whether the wifi password entered is correct.

Confirm the English case and click the "eye icon" on the password input screen to check the password.

2. Reconnect to WiFi

Go to the phone settings - WLAN, long press the connected wifi, select "Forget Network", and reconnect the wifi.

3. Restart the router.

Disconnect the router from power, power it back on after 10 seconds, and wait for the router to boot up and connect to the carrier network (about 1 2 minutes is expected).

4. Check the router settings.

Check the router manual, enter the router settings interface to see if there is a restriction on connection, if it is restricted, you will not be able to connect to wifi.

5. Use other mobile phones around you to compare and test.

Use the comparison method to observe other mobile phones connected to the same wifi to confirm whether it is the wifi cause or the mobile phone reason, and you can also connect your mobile phone to different wifi (or personal hotspots) for comparison test. If other phones can't connect to wifi, it's a router or broadband problem.

6. Upgrade the system version.

The new version of the system has improved the compatibility and stability, optimized the performance, and entered Settings - System Upgrade (some models are: Settings - My Device - iQOO UI Version), you can view the system version information. If it's not the latest version, it's recommended to upgrade the experience.

7. Restore factory settings.

Abnormal system configuration information may cause failures, so we recommend that you back up important data and restore all settings.

Operation method: Enter Settings - System Management - Backup and Reset - Restore All Settings (some models are: Settings - More Settings - Restore Factory Settings - Restore All Settings), operate according to the on-screen prompts, the operation will cause the logged third-party software to need to log in again, but will not clear the **, ** and other files in the phone storage, please confirm that it does not affect the use of some third-party software before restoring all settings.

To avoid data loss due to abnormal operation, it is recommended to back up the important data of your phone first.

What should I do if my phone can't connect to wifi?

Boot it up and restart it to try.

Restart the WiFi hotspot or change the name of the WiFi hotspot.

See if your phone is on the option to turn off the network while hibernating, and if so, turn it off. Many people report that their mobile phones often disconnect from the link or cannot receive messages from background chat software, which is mostly because they inadvertently turn on the option to hibernate and turn off the network.

Secondly, if all of the above is normal, there is also a possibility that the most important router is faulty. Questions include:

1.The router is stuck in an endless loop and needs to obtain IP addresses continuously. This is a relatively common problem, and in the face of this problem, you only need to open the route again every ten minutes or so.

2.A wireless router may have too many devices connected. In this case, the pressure on the router is too great, and it is easy to cause IP conflicts and cannot connect to WiFi. In this case, you need to set a static IP address for each device to solve the problem.

3.Change the authentication type of the router. If you don't understand this setting, then the authentication type is in the "automatic" state, just select it as the more secure "WPA2-PSK" and change the encryption algorithm to "AES".

Finally, if your phone still can't connect to WiFi after completing the above operations, then it is very likely that your router firmware is compatible with your phone. At this time, you can choose to upgrade the router firmware, and the upgrade method will be different for different brands, which can be upgraded according to the upgrade page or the upgrade method on the Internet; If the above still doesn't solve the problem, you may need to flash the phone ROM to solve the problem.

1. Check whether the wifi password is correct.

It is recommended to click when entering a password"Eye icon"to display the password and make sure that the password is correct.

2. Reconnect to WiFi

Please go to Settings --WLAN, click on the wifi you need to connect to, and click"Forgot Network Forgot password"reconnect.

3. Check whether the wifi network is normal.

Please compare whether the same wifi connection is normal with other mobile phones, and confirm whether it is the wifi or mobile phone. If the return is due to wifi, please restart the wireless router to view. At the same time, you can enter the router management interface to check whether there are special functions set before the car:

Such as the number of connections limit, MAC binding, Internet time management, etc.

4. Reset network settings.

Do a good job of backing up wifi and other data, close the speed and go to Settings - System Management - Backup and Reset - Reset Network Settings - Reset Settings, and then use to view.

Note: Resetting the network settings will clear the connection records such as Wi-Fi, mobile data network, Bluetooth, etc.; If you have dual SIM, you need to select the corresponding SIM card.

After performing the above methods, if the problem persists, please go to the local vivo customer service center for testing. (Customer service center address: enter vivo official website vivo**app--my--service outlets, after-sales outlets--select provinces and cities to query the address of the customer service center).

What should I do if my phone can't connect to wifi?

Turn the Wi-Fi switch off and on again to try to restore it. There is a temporary failure in the system that may cause the hotspot to not be searched. It is recommended to be closer to the router and scan it again. If the distance is too far, you may not be able to search for the hotspot, or you can turn off the phone and restart it, and turn it on to see if it can be restored.
