When using a computer, we often encounter situations where the network connection is restricted or cannot be connected. 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, the IP address and obtain information
when the network can not connect, the first time think of is to view your IP address information. We can enter ipconfig or (ipconfig /all view details) on the command line (cmd) to view.
If we get the IP address of the normal network segment of our company network or the IP network segment set by the router at home, this is normal. 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 events occur or IP address is 169 which represents the beginning of time and did not get the card to the correct IP address.
If we are to obtain an IP address via DHCP, then the Internet, then you can use ipconfig /release command to release the existing IP address information, and then use the ipconfig /renew to obtain the appropriate IP address from the 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 mark is displayed on the network icon! At this time, you need to set the IP address to be dynamically acquired.
