This article mainly introduces why the network connection is abnormal in the computer network, the article is very detailed, has a certain reference value, interested friends must read it!

The reasons are: 1, broadband itself problems, directly connected to broadband network cable testing; 2, router problems, restore factory settings; 3, network card driver is not or inappropriate caused, network cable interface or network cable is not a problem; 4, caused by system problems, it is recommended to restore the system or reinstall.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

1) if it is the problem of broadband itself, first of all, directly connect the broadband network cable test, if it is the problem of broadband, contact the broadband customer service to solve.

2) if it is the problem with the router, if it can be used but can not be used for the time being, my own practice is to disconnect the power supply of the router and plug it in. I'll have a look later. When there is, you can restore the factory settings, and you can use them strictly according to the instructions. You don't understand, and you are not recommended to set them at will (this is due to the slow or failure of the router to find the IP address when the physical connection is correct, and it does not mean that the router is broken).

3) if the wireless switch is turned off and on, if the wireless is connected by software, it is normal that the software is not easy to use and there is often something wrong with it. There is no better way to use the router. In addition, there is no network card driver or inappropriate cause, network cable interface or network cable is not a problem, and so on.

4) if it is caused by a system problem, it is recommended to restore the system or reinstall it.
