Dear Lenovo users, hello!

Wireless is restricted, you can change the IP, reset DNS, WinSock, turn off the optimization software and WiFi software (Win8 system, you need to turn off wireless energy saving, enable FIPS compatibility mode) If it is invalid, then reinstall the driver.

P.S. How to reset DNS:

Enter netsh int ip reset in cmd and press enter to execute the order.

Then enter: ipconfig flushdns dns enter to execute.

Then type: netsh winsock reset, press enter to execute.

Maybe it's the operator's business, not the computer's fault.

There are several reasons why you can't connect to the Internet due to restrictions on WiFi

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.

You can first check the network environment, whether the wireless network is turned on, to see if other machines can access the Internet, if other machines can access the Internet, and only a few network connections are not on the trip, delete the network where the nest is saved, and reconnect. If it is invalid, check the IP, DNS, and channel.

If QQ can be uploaded but the web page cannot be opened, please reset the browser, DNS, WinSock.

If you can't even get on QQ, look at the network icon in the lower right corner.
