Why can Lenovo A820 connect to WiFi but can t access the Internet

Dear Lenovo users, hello!

We apologize for the inconvenience caused to your device.

According to the description, the mobile phone can connect to the wireless wifi network normally, but it cannot access the Internet. It is recommended that you try to test this wireless network with a different mobile phone connection first.

1. If you can't access the Internet normally, it means that the wireless wifi network itself is a problem.

For example, it may be caused by the wireless router itself not being able to access the network. If the network cable port connection is abnormal, the wireless router does not set up automatic dialing, the wireless router is abnormal, etc., you can try to plug and unplug the network cable related ports, or restore the factory settings of the wireless router to see if it can be solved;

or the network used by itself can only allow access to one computer terminal (for example, some cell networks are bound to MAC addresses);

Check it out. 2. If other mobile phones can connect and surf the Internet normally, it means that it is caused by the problem of your mobile phone.

It is recommended that you try to check whether there are any relevant software settings to limit the networking function of the program, such as Lenovo Security - Networking Management.

At the same time, it may also be caused by some software conflicts, it is recommended that you back up the important data of the body, and then restore the factory settings of the phone to see if it can be improved. (Operational under Phone System Settings - Backup & Reset)

If the problem persists and cannot be effectively solved, we recommend that you take the time to go to your local Lenovo after-sales service center and let the engineer help detect and solve it.

You can log in to the official website to check the address.

There are several reasons why the computer is connected to wifi but cannot access the Internet

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 be unable to 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 ruled out, 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.

Hello, I am repairing the mobile phone, according to the situation you said, it should still be the mobile phone is not set up, if there is no problem with the setting, see if it is within the range of acceptance, if there is no problem, it is a problem with the mobile phone software, you need to go to the after-sales service or mobile phone repair shop to brush the machine, ten yuan is OK, more than not to pay for him.

Dear Lenovo mobile phone users, hello!

If your phone can't connect to WiFi, it is recommended that you try to confirm whether it is caused by the wrong wireless password.

If the password is correct, the wireless wifi network itself is not related to setting restrictions, and other mobile phones can be connected normally, we recommend that you can back up the important information of the mobile phone (contacts, text messages, etc.), and then operate the factory settings of the mobile phone to see if it can be solved. If the problem persists and cannot be effectively solved, it is recommended that you take the time to go to the local Lenovo after-sales service center and let the engineer help detect and solve it, which may be caused by the corruption of the relevant system files or the abnormal WiFi module on the motherboard.

If you have any other doubts during the subsequent use of the mobile phone, you can also log in to the "Lenovo Official Lewen Bar" to pay attention to the latest netizen consultation for reference. Have a great day!

Maybe you didn't enter the connection password correctly. Maybe it's a false signal that the signal is stuck. Maybe it's a network failure. Of course, the last possibility is that there is something wrong with your phone.

We apologize for any inconvenience this may cause and affect your use.

If you have other wireless networks nearby, please try to compare:

a. Other networks can be connected normally, you can judge that the mobile phone system and hardware function are normal, please try as follows:

1. Password correctness: In most cases, it is caused by the failure of password verification, it is recommended that you try to confirm whether it is caused by the wrong wireless password input, you can verify it by modifying the encryption method or canceling the encryption;

2. Wireless network signal: When the wireless signal signal is weak, it may lead to the inability to connect normally or the application cannot be connected to the network normally, it is recommended to move the mobile device to the wireless network signal is strong to try;

3. Abnormal wireless network parameters: In order to avoid abnormal connection due to abnormal wireless network parameters such as DNS, it is recommended that you try to set the wireless network as a static IP assignment, and the static IP setting menu of the product is as follows: System Settings - WLAN - Advanced - IP address, please refer to it.

4. If the above suggestions still cannot be improved, it is not excluded that the compatibility between the routing equipment and the product is caused, and it is recommended that you replace the wireless network or routing equipment for use;

b. If other networks cannot be connected normally, it may be caused by abnormal system or hardware functions

1. Please back up the fuselage data and try to restore factory settings;

2. If it still cannot be improved after recovery, please take the time to go to the local maintenance site to test and process the system and hardware.

If the conditions are limited and you cannot compare with other wireless networks, it is recommended that you conduct a simple investigation based on the above suggestions, and if it cannot be improved, please send it to the repair site in time.

I don't know what you're talking about, if you already have a wireless router 1, and this wireless router is already able to access the Internet, then another wireless router 2, you need to connect the line to the WAN port of the wireless router 2, and then set up a static IP Internet access to the wireless router 2, I think so, although I haven't tried it, but I've been in contact with it before, similar to this process.

Hello, it is recommended that you enter the router setup interface, install the setup wizard, re-set the router, and after the setup is completed, restart the router and connect it again for testing.

Please make sure that the wireless router has been connected to the Internet through the cat and whether it is really connected to the wireless network.

If they don't ask questions, try to check the boot items, like 360 and Tencent Computer Manager, which will automatically turn off some infrequently used startup items to improve the boot speed, and change the relevant wireless settings to the startup items. If you can't go to the browsing settings, open the "Manage Add-ins" and load them all ......

If the router requires a password, enter the password, and if the router has an IP bond, you need to enter the IP
