Lenovo a766 can make a phone call, but what should I do if I can't surf the Internet?

I'm sorry for the delay in your use.

A: As you said, A766 mobile data cannot be connected to the Internet. Here, I suggest you refer to the following troubleshooting steps:

1 and A766 can both use mobile and Unicom cards. Please confirm that the sim card used is within this range.

2. Please check whether the data switching service is enabled, that is, drop down the notification bar to open the data connection;

Please check whether the arrears have been paid. If the balance is insufficient, please try to make up the arrears to the operator.

4. It is suggested that you replace other mobile phones or compare the usage of other users of the same operator around you. Do not rule out the poor network environment. If it appears in individual areas, it is recommended to change the network environment as much as possible;

5. If it is possible to change other sim cards, it is recommended that you change your sim card for comparison. If individual sim cards can't surf the Internet normally, it is not ruled out that it is a compatibility problem. It is recommended to contact the operator for specific testing and handling.

6. It is recommended to try to switch access points. The path is as follows: System Settings-More-Mobile Network-Select the name of SIM card, switch the options to different access points and try to restart;

7. Please verify whether the device has traffic monitoring settings, such as built-in music security, 360 mobile guards and other software settings.

9. If the above operations cannot be improved, you can connect to the network normally before. It is recommended to back up the fuselage data and restore the factory settings as much as possible.

If the problem cannot be effectively solved after the above operation, for your normal use in the future, it is recommended that you take time to go to a nearby Lenovo authorized maintenance station for specific inspection and treatment.

B: As you said, A766 successfully connected to the wireless network, but could not access the Internet. Please refer to the following situations and methods to try:

If there are conditions around to connect to other wireless networks, please try to compare:

A. If you can connect to other networks normally, you can judge that the mobile phone system and hardware functions are normal. Please follow these steps to try:

1. Availability of wireless network: It is recommended that you use other devices to connect to the wireless network and compare whether you can connect to the Internet normally. If you can't connect normally, it is recommended to reset the wireless network, such as changing channels and changing encryption methods.

2. Do you need to dial? Some telecom network users use ADSL to access the Internet, and they need to verify their identity through PPPOE dialing. Mobile devices can't verify it, so they can't connect to the Internet. For details, please contact Telecom Customer Service (Telecom Customer Service Hotline: 10000) for further consultation.

3. Number of wireless network connections: There may be too many users who use the current network connection to use the network normally. It is recommended to try it in your spare time;

4. Wireless network signal: When the wireless signal signal is weak, it may lead to the failure of normal connection or the failure of normal networking of connected applications. It is suggested that mobile devices try to go to places with strong wireless network signals;

5. Wireless network restrictions: Some network service providers or network departments will restrict the use of wireless networks, such as binding the mac addresses of devices that can be used. It is recommended that you check with the corresponding network service provider or manager;

6. Wireless network in public places: If you access the wireless network provided by merchants or operators, you may need to verify additional information such as user name or verification code. Usually, after the connection is successful, you can open the browser and enter the corresponding user name and password for normal use. For details, please consult the customer service of merchants and operators.

7. If the above suggestions still cannot be improved, the compatibility problem between routing equipment and products will not be ruled out. It is suggested that you replace the wireless network or use routing equipment;

B. Other networks cannot be used normally after connection, which may be caused by abnormal system or hardware functions:

1, please back up the fuselage data and try to restore the factory settings;

2. If you still can't improve after recovery, please take time to go to the local maintenance site to check the processing system and hardware.

If the conditions are limited and can't be compared with other wireless networks, I suggest you do a simple survey according to the above suggestions. If it cannot be improved, please send it to the maintenance site in time.
