What should I do if the computer Win8 network is not connected? Network connection is not a solution.

We often encounter situations where the network connection is restricted or cannot be connected during the use of the computer. There may be many reasons for the problem. Of course, some people have resorted to the computer to kill the technology "restart the computer" can solve the problem, but this nirvana can not solve the problem in most circumstances. Next, combined with Microsoft's latest Windows8 system, we explained the situation in which the network connection we encountered was restricted or connected, which affected the use of the network. I hope to help friends who have encountered such problems.

If you are using the Win8 system and you are prompted to connect or the network is restricted, you may not be able to access the Internet. The cause may be various. For example, some incorrect settings of the operating system, Internet terminal settings such as routers or cats, and hardware failures such as network card cables. In short, when we use Windows 8 when the network is restricted or unable to connect, you may wish to try the following methods, or you will find a solution to your current problems.

First, check the network cable

Make sure that the network cable is no problem, I have encountered friends before repairing the computer and said that the Internet is not available. As a result, it still could not be solved for a long time. Finally, it was discovered that the network cable was not plugged in or the network cable had a problem. In order to avoid this embarrassing phenomenon, the first step is to explain this situation. Otherwise, it will not be inserted into the network cable for a long time. This is a "single glory". If you have a big red cross on the network icon in the lower right corner, you should first check if the network cable is plugged in. If the network cable is plugged in and functioning normally, a yellow light flashes along the place where the desktop cable is plugged in and the place where the notebook is plugged into the network cable. If the indicator light does not flash, it means that the network cable is not plugged in or plugged in and does not work.

Second, re-acquire IP address information

When the network can not be connected, the first thing that comes to mind is to view your own IP address information. We can enter ipconfig or (ipconfig /all view details) on the command line (cmd) to view.

This is normal if we are getting the IP address of the normal network segment of our company network or the IP network segment set by the router at home. If the IP address information is not the network segment set by the environment, this is an abnormal situation. You need to reset the IP or re-acquire the IP address.

If the following occurs or the IP address starts with 169, this means that the network card does not get the correct IP address.

If we obtain the IP address of the Internet through DHCP, then we can use the ipconfig /release command to release the existing IP address information, and then use ipconfig /renew to obtain the appropriate IP address from DHCP. This method can solve some cases where the correct IP address information, DNS, etc. are not obtained. Sometimes, if the IP address is manually configured in a DHCP environment, the connection is restricted or an exclamation point is displayed on the network icon! The IP address is set to be dynamically acquired.

Ipconfig /release releases address information.

ipconfig /renew gets the new address information.

Third, diagnose network connection

Solve network problems, Windows has a very good tool called "Windows Network Diagnostics", use it to help us check the cause of some problems. Open the network adapter of our computer. If the notebook is connected to the network by wireless, just open our wireless network adapter network adapter. At this time, click “Diagnostics” in the lower right corner to open the Windows network diagnosis<;Check:

At this time, a wizard will pop up for automatic diagnosis. In some cases, it will be fixed automatically, and some problems can be solved by using Windows diagnostics.

If you check out related issues, you can fix them based on the problems found.
