Win7 system network connection is not how to solve

How to solve the win7 system network connection

How can I not connect to the network? The following small series will introduce the specific solutions for you.

Specific solution:

1, first look at the icon in the lower right corner, like the above connection is normal, if the error can check the user name and password is wrong or expired. And the icons like the one below are not normal.

2. If the icon above appears, you should first check if your cat or router is connected and the cable is secure. Secondly, check if the NIC driver is installed, or upgrade the NIC driver! There is basically no problem with the NIC icon in the device manager. Let's start with the soft setup.

3, if such a prompt appears during the connection process, most of it is caused by a password error, remote device does not recognize, this time

You should think about whether you put The password is wrong, and broadband is not arrears. If you are not, you can call the customer service, it is best to call the broadband provider to turn broadband faults, which is more effective than directly looking for maintenance personnel in the community department.

4, if the above situation occurs, the author believes that there may be a situation in which broadband operators such as China Unicom have not given the original account in order to increase the profitability of using their own dial-up software. Operator + counting device (multiple refers to Henan Unicom) can calculate the real broadband account to use the system's own broadband connection to dial. (Incorrectly downloading the software, it is a virus.)

5. If the problem has not been solved, you can try to check if the cat's indicator light is normal and reset the settings for the cat. Or restart the system to connect again.
