How to solve the instability of Win7 network?

If our network is unstable, it is a troublesome thing, and it is something we don't want to see. Recently, users who use the Win7 system responded that his network was very unstable. When the game was playing, the network connection was suddenly disconnected. After a while, it was connected back. How do you solve such a problem? Now Xiaobian will talk to you about the unstable solution of Win7 network.

The specific steps are as follows:

1, the server problem

The first is the network service provider, such as the user's telecommunications, if the service operator's network is unstable, So how to set it up is useless. So first make sure the server has to be stable. Of course, the server of the website also includes the inside of it. Some of the servers whose servers are foreign are very slow. All of them are slow to open the webpage even if we are fast.

2, network cable failure

Then we are connected to the network cable, if you used to use the telephone line connected network. Then, in contrast to the fiber behind, it is the hut that sees the big house. Therefore, the network speed is unstable and it is normal. The network cable problem also includes the wiring standard of T568A/B not used when wiring. T568A twisted pair It has 4 lines, including 1 and 2. Used for sending, so you must pick up a pair. There are also 2 wires that are 3 and 6. It is the line that receives the information, so it must also be connected to a pair. This will ensure the normal transmission of data. If standard wiring is not used, the network speed will be unstable. So wiring is also very critical.

3, router settings

Now is the reason for routers and cats. Of course, as long as the line is connected normally, the interface is not loose and there is no bad contact, and the router is set up, the router can be eliminated. It is recommended to restore the router to its original state and let the router rest. Restart the router. Then check the dns and ip address when the settings are correct.

4, NIC failure

Then there is a hardware problem. Check whether it is a problem with the network card. The network card used by the user is generally a PCI network card or an on-board network card. If you choose it, you must choose a better quality. Otherwise, the quality of the Internet may be poor. Then the NIC socket is re-plugged. Whether there are other electrical appliances on the side of the computer that interfere with the network, and maintain a certain distance to these appliances such as air conditioners, refrigerators, and televisions. The network card also includes the network card driver, all of which can be detected in the [right click on my computer - device manager - network adapter] to detect abnormalities. Then install it as normal. As shown in the figure:

5, the existence of a loop on the network is also one of the reasons for the slow speed. Because there are more complex networks on the network, there are more nodes, such as Internet cafes, office places, and many connections. All this will create a loop in the face of the unintentional. In order to avoid this, we must develop good habits when laying the network cable: the network cable is marked with obvious labels, and the places with spare lines must be recorded. When such a failure is suspected, the method of stepwise segmentation is generally adopted.

6. A port in the network has formed a bottleneck and the network speed has become very slow.

This is where we use routers and switches to connect to the network, and then router WAN ports and LAN ports, switch ports, hub ports, and server NICs can become network bottlenecks. Of course, when this happens, you can use some software to view the data traffic of the router and switch, and then use Netstat to view the data traffic of the statistics port to check the specific location of the data bottleneck, and then increase the bandwidth to solve it. The port bottleneck is faulty.

7, the computer is worm virus

Now that the computer is infected with a virus, there will be a large number of programs running in the background, taking up a lot of network speed, all networks are not The normal reason is here. There are also some worms that have an impact on the speed of the network. The worm will send emails to the outside world, which will cause the server to be busy. If it is verified, it will be a local area network. All computers must be regularly checked for viruses and some Trojans, so that the network speed will not be disturbed if the network is normal.

8, insufficient system resources

There are too many programs open on the computer, causing system resources to be abnormal. The local solution to this situation is simple. It is to close some processes and boot programs that are not used very rarely. When there are unknown processes running in the background, you can end them. Click [Start-Run], enter the [msconfig] command in the run box to confirm, and then disable some boot programs. As shown:

9, the firewall level is high

The user has opened too many firewalls, the firewall level is set too high. Some netizens have turned on 360, Windows and Jinshan firewalls. This will drag the speed of the network. All suggestions are available. Of course, if the level of the firewall is turned on, it will affect the network speed. All suggestions are to turn off or minimize the level of the firewall.

10. Finally, if the line and router settings are normal, reinstall the system.

The above is the entire content of the Win7 network instability solution. There are many reasons why the computer network speed is not strong. However, network instability often occurs. It is indeed a troublesome thing. It is not good to watch videos, and it is more fun to play games. Try the above solution!
