This article mainly shows you "what are the common reasons for win10 network disconnection". The content is easy to understand and clear. I hope it can help you solve your doubts. Let the editor lead you to study and learn the article "what are the common reasons for win10 network disconnection".

1. Power management of windows system

Now when many notebooks of windows system install native operating system, in order to save power and prolong the battery life, the system sets the power management of the network adapter (that is, the network card) to "allow the computer to turn off this device to save power". In this way, as long as your notebook watches the video or plays the game a little bit, as soon as the power consumption is high, the system will automatically turn off your network card, can the network not be offline? In view of this situation, you need to right-click "my computer", open the device manager, find the network adapter, double-click the network card that is using a wired connection, and uncheck this function in power management, so that even in the case of high power consumption, the system will not turn off the network card.

2 the problem of network cable and crystal head

The network wire is generally divided into copper wire and aluminum wire, which is divided into one to seven types of lines according to the different data and transmission rate. Now the most commonly used local area network for household and small and medium-sized enterprises is aluminum wire. Its biggest advantage is that it is cheap, but it is also prone to problems. The network cable may break after it has been used for a long time, and the crystal head may be oxidized after a long time of use, resulting in the data can not be transmitted. Then it also caused the network outage. To troubleshoot this problem, you can buy a special tool to detect the connection or disconnection of the network cable in the market, and it is also very easy to use. Turn on the computer and router, and scan the network cable with the tool. If the network cable is normal, there will be a beep. The louder the sound, the better the transmission quality. Of course, you can also directly change a network cable to try.

3 improper configuration of IP address release time leads to IP address conflict

The release time of the so-called IP address means that when a computer is connected to a router, the router equipped with DHCP will automatically assign an IP address to the computer. When the computer gets the IP address, even if the computer is turned off, within the release time of the IP address, the router will still retain the corresponding IP address of the computer instead of directly releasing it. When the release time of the IP address is exceeded, the IP address will be released by the router and reassigned to other users. So here's the problem. For example, suppose the IP address set by the router is released for 1 day, and a computer gets the address 192.168.1.100 on the router. After using it for a period of time, it shuts down, and then there is another computer that uses a static IP address, and its IP address happens to be 192.168.1.100, so when two computers are online at the same time in one day. There will be an IP address conflict, then a computer must be offline.

(4) the duplex mode of computer network card is not configured properly.

The duplex mode of computer network card is divided into half-duplex mode and full-duplex mode. Half-duplex mode means that sending and receiving data cannot be carried out at the same time and must be separated, while full-duplex mode can be carried out at the same time. For example, the network is equivalent to a bridge, and the machine that needs interactive data is equivalent to the car to cross the bridge. if the bridge is not wide enough, one car can only be allowed to pass first and wait for another car to pass, that is, the sending and receiving are not the same. This is half-duplex; if the bridge is wide enough to allow two cars to pass at the same time, then two cars can pass at the same time, that is, sending and receiving at the same time, this is full-duplex. It is obvious that full-duplex is much more efficient than half-duplex, but at the same time the performance requirements are much higher. Another example: the bridge is spacious enough to allow two cars to pass at the same time, but the bridge can only bear the weight of one car. if two cars pass at the same time, the bridge will collapse, which is corresponding to the collapse of the network. the line is cut off. Many computers leave the factory in order to pursue the data transmission rate, set the duplex mode of the network card to the most ideal state, such as 1Gbps full duplex, if the performance can not keep up, then it will lead to network disconnection.

If this happens, you can right-click "my computer", open the device manager, double-click the wired network card that is in use, click Advanced, and find "connection speed and duplex mode". According to the actual situation and performance of your computer, choose the appropriate connection speed and duplex mode, try to lower it one level, if the problem is solved. It shows that the performance of the machine is not enough to support such a high speed and the corresponding duplex mode, so it is necessary to adjust the connection rate and duplex mode.

5 computer virus

Computer viruses can not only slow the system down, but also steal confidential information, and even delete system files, such as the configuration files driven by the network card. Once the configuration files driven by the network card are lost, the connection must have failed. This will cause disconnection. Computer virus detection and killing I believe that most people will, now the application market is a lot of third-party antivirus software, such as 360 security guard, Kaspersky, Jinshan guard, etc., but if it is a stubborn virus can only reinstall the system, third-party antivirus software can not find out, very secret.
