The cause and handling of Wi Fi wireless connection are as titled Thank you

I don't know what wifi yours on the device but most of them can't connect to those points, the password is not right, the connection is restricted, the signal is not good, **There are too many users, there seems to be nothing else (IP setting problems are not necessarily).

1. Radio interference Radios can come from a wide range of consumer electronics, such as cordless**, Bluetooth headsets, microwave ovens, and even electric garage doors, all of which can interfere with the proper functioning of Wi-Fi wireless signals. Workaround: Move away from or away from these devices, if the wireless signal is restored or stronger, the source of the problem has been found.

2. Insufficient radiation Even if there are no other interfering devices, it is possible that the Wi-Fi network itself does not have enough radiation coverage, resulting in an unstable wireless network. As you know, the connection status of the Wi-Fi network is closely related to the distance between the terminal and the AP. Workaround:

Minimize metal obstructions that affect the link, or shorten the distance to the AP. A more feasible approach is to consider installing an antenna for better wireless transmission. 3. Linking to the wrong network If there are 2 Wi-Fi networks with the same network name in the wireless network environment you are using, then you are likely to link to the wrong network and affect your normal Internet access.

In this case, the signals often interfere with each other or the radiation range is insufficient. In addition, if another network is down, it will also affect your computer's Internet access. 4. Network drivers or firmware are not upgraded in time Every computer linked to the Wi-Fi network must use its built-in network module and related drivers to achieve wireless Internet access.

Drivers affect the functioning of various functions of Wi-Fi hardware. In addition, the wireless router and the firmware responsible for accessing the wireless Internet are also affected by the same as the driver. Workaround:

Uninstall the outdated drivers and firmware before installing the latest version of the corresponding wireless module component. 5. Incompatible software If your computer is not connected to the wireless network from the beginning, then it is likely that your computer has incompatible software installed and running. This includes software that contains operating system patches, operating system service components, or other software that affects the system network.

Solution: Make a record every time you upgrade or install software, and uninstall incompatible software, or simply restore the system. 6. Overload of routers (access points) Some people have reported in the past that overload of routers or access points will affect the speed and quality of wireless Internet access.

The main reasons for overloading the router are: gaming, BT or too many computers connected to the network, etc. Theoretically, a large amount of data transfer will generally cause the router to be temporarily disconnected.

In addition, if the temperature of the router is too high, it may also drop the call. Solution: The place where the router is installed should have a good ventilation environment.

If the router is not suitable for your use (such as requiring a high data transmission capacity), consider replacing the router.

1. Go to Settings - Other Networks and Connections - Private DNS, check whether private DNS is set, if it is enabled, it is recommended to set Private DNS to off and try again.

2. Check WiFi

Please compare whether the same wifi connection is normal with other mobile phones, and confirm whether it is the wifi or mobile phone. If it is due to Wi-Fi, please restart the wireless router to check. Some public Wi-Fi networks require browser authentication before they can connect to the Internet.

3. Check the network permissions.

Please go to iButler - Traffic Management Traffic Monitoring - Network Management - WLAN - Turn on the software networking permission.

4. Check the environmental causes.

If the phone is far away from the router, although the wifi signal is displayed, it may not be able to access the Internet, it is recommended to adjust the distance between the phone and the router before trying.

5. Reset the network settings to call the sails.

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

1. Enter the cloud service - data synchronization - turn on WLAN, Bluetooth, etc. to synchronize data to the cloud service.

2. Go to "Cloud Service" -- Device Cloud Backup -- Backup Data Type -- Open "System Data" -- Return to the previous page -- Back up now, and back up some system settings data.

6. Reset all settings (do this when you can't see the reset network settings menu).

This action does not delete the software or files, only resets all the settings; For data security, you can back up important data before operation.

Note: Go to Cloud Service - Device Cloud Backup - Backup Data Type - System Data - Return - Back to Back Up Now to back up some system settings and desktop layout; Cloud service--Data synchronization--Turn on WLAN, Bluetooth, etc. to synchronize data to cloud service.

7. Service center testing.

If the above methods fail to help recover, the customer service center needs to be tested and processed, the customer service center address: enter the vivo official website vivo**app--my--service outlets after-sales outlets--select the province and city to inquire about the customer's address of the high-end service center;

Tips: It is recommended to bring relevant purchase vouchers (such as: purchase invoice, warranty card, ID card) when you go, and consult the staff of the consulting center in advance to ensure that the staff go again during normal working hours, avoid empty running, and pay attention to safety on the way to and from the service.

The possible reasons why the Wi-Fi connection does not work are as follows:

1. The wifi itself is a problem, and the wifi may not be connected normally, resulting in the inability to access the Internet.

2. Router problems, the router may be overheated or damaged.

3. Broadband arrears may lead to inability to access the Internet.

4. The wifi name contains Chinese, which causes some computers to regret that they cannot connect to the Internet.

5. Computer system problems, there may be problems with the system, resulting in connecting to wifi but unable to access the Internet.

Suggested workaround:

1. Use other mobile phones or devices to connect to wifi to try whether you can access the Internet, and rule out the wifi itself.

2. Restart the router to try, or restore the router to factory settings, then dial up the Internet again, and reset the wifi according to the setup wizard, or change to a new router and dial up to connect to the Internet.

3. Contact broadband customer service to confirm whether there is any abnormality in the broadband, such as arrears, recharge the broadband, and then dial up the connection.

4. If the wifi name contains Chinese, it is recommended to modify it to English or a combination of English and numbers before connecting.

5. If the above reasons are all in the way, it is likely to be a computer system problem for a long time, and it is recommended to restore the factory settings. See if that solves the problem.

1. When you can't connect to Wi-Fi, it is most likely that the password is incorrect, and you can connect as long as you re-enter the password.

How to do it: Go to Settings - Wi-Fi - Click the i after the name - click Forget this network, then reconnect to this network, and then enter the correct password.

2. Because there are too many routers around you, the transmitting power is not the same, and the default channel of the router is 6, which causes the signals to interfere with each other, which leads to problems with authentication. The best way to have this kind of problem is to modify the router channel.

Specific method: Enter the router settings interface from the browser - wireless settings - wireless basic settings - channels, just select the appropriate channel, and you can automatically do it.

3. The password is correct, but there is a problem with the identity verification, which may be a problem with the input method, we had better use the system's native input method to enter the password, and pay attention to the capitalization.

How to do it: Settings - General - Keyboard - Select the keyboard that comes with the system.

4. The encryption method of the mobile phone and the wireless network password of the route are different, generally using WPA-PSK WPA2-PSK, and using AES for encryption, mainly for security, it is difficult to crack, and it can be solved by trying more encryption methods.

Specific method: Enter the router settings interface from the browser - wireless settings - wireless security - security mode.

If you are using a Huawei phone and can connect to Wi-Fi but cannot access the Internet, you can use the following methods to troubleshoot the problem:

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

1.If connected to other wifi is normal.

1) Please do not stay away from the router;

2) Please check whether the broadband account expires, restart the router and restart the phone before trying;

3) If the router has been set to the blacklist and whitelist, you need to check whether the MAC address of the mobile phone is added to the router, if the router does not set the blacklist and whitelist, please power off the router and restart the attempt.

2.If you connect to other wifi, you can't get online.

1) Please turn the WLAN switch back on and try to connect;

2) It is recommended to search for Restore Network Settings in Settings and follow the on-screen prompts to restore. (Note: This restores the Wi-Fi, mobile data, and Bluetooth connection records and deletes the Wi-Fi and Bluetooth connection records).

2. If you are using a public network:

1.Try using it in a place with a small amount and confirm that the hotspot is working properly.

2.Please check if you need to log in through a browser** to register before you can access the Internet.

3. If individual applications are not available online:

Please open Settings, enter Traffic Management in the search box above and click to enter the Traffic Management page, click Application Networking, and check whether the WLAN permissions are checked for individual applications.

If the problem persists, we recommend that you back up your data (third-party apps such as QQ and WeChat need to be backed up separately) and bring your purchase voucher to the Huawei Customer Service Center for testing.

What is the reason why the mobile phone wifi connection is not available?

See if there's a password restriction or if the network connection mode is incorrect.

Hello, wifi signal regardless of whether there is a network mobile phone and other equipment can be connected, the user can not use the network after connecting to wifi, first confirm whether your broadband line is smooth, you can check whether the indicator light of the broadband cat has LOS red light flashing, if there is a broadband failure, so the router's wifi can not use the network, at this time, the user can call the operator's customer service to report the fault processing, after the fault report, there will be staff to come to the door to troubleshoot.

If the broadband modem can be connected to the network normally, then it is a problem with the router, and you can check whether the network cable is connected correctly. If the network cable between the broadband modem and the router is normal, you can restore the router to its factory value, and then reset the router parameters to see if it can be restored to normal

2. Then open the browser and enter the management address and login password of the router.

3. After logging in to the background, click the setup wizard, and then fill in the corresponding parameters according to the wizard instructions.

6. After the wireless setup is completed, click Save, and then restart the router to use it normally.

If you are using a OnePlus phone and cannot connect to Wi-Fi, we recommend that you perform the following steps:

Confirm that your router is turned on and that you are within range of your router's signal. If you are too far away from the router, you will not be able to get the signal from the router. Make sure that your location is within the range covered by the router, that the wifi signal can be searched, and that the signal is stable.

Confirm that the wifi password is entered correctly.

Check whether the router server has set restrictions, such as MAC address or IP address filtering permissions, etc., in this case, you can contact the router administrator to deal with it, or try to change to another WiFi router.

If you were able to connect in the past but cannot connect now, it is recommended to restart your phone and router separately.

It is recommended to cancel the wifi to save the password and re-enter the password to connect.

If the problem persists, we recommend that you reset the Wi-Fi, Bluetooth, and mobile data network settings after backing up the data, in the following path: [Settings] - [Other Settings] - [Reset Phone] - [Reset Wireless Settings].
