Lenovo laptop can t connect to the network, I use Telecom Tianyi dial up Internet access.

I think there is a problem with what you asked, if you have a route, you should be able to go to the Internet directly, no need to dial up the connection, the router has been dialed up, and you can open the web page directly.

If you are connected to a router, it is recommended that you connect the network cable of the computer directly to Moneo and then dial up to connect, that is, to enter the username and password, if you can connect then there is a problem with the router, if there is a problem with the router, you can enter enter enter in IE, run the setup wizard, select the item of P is not dynamic nor static, the next step is to enter the username and password, save. Or try resetting the router.

Secondly, I think 651 is similar to 691 in win7, check whether the username and password you connect to broadband are correct, and secondly, check whether your broadband account is in arrears, if it is in arrears, it will also appear in the situation you described.

Hello, error 651 is a connection problem, check whether the modem is normal or replace, you can also press F8 to enter safe mode after booting, uninstall the current wireless network card driver, restart the computer and install this driver on Lenovo official website**, do not use third-party software may appear system instability, if it is invalid, you can contact the service station to detect whether the hardware is normal.

It's the same thing that can be connected.

Estimate that there is a problem with your system.

If there is no connection to the Internet, it is a problem with the settings, please use the following method:
