The daily use of the computer at the same time some friends may encounter is on the internet or just turned on the computer when prompted network cable was unplugged, such a phenomenon makes people very disgusted, the general phenomenon is not the computer network is not connected to the network is always interrupted, so that users can not carry out normal network applications, then how to solve such a phenomenon? Let's first analyze how we can create such a phenomenon.

The reason the network cable was unplugged:

Because of the network cable interface with magnetic field or magnetic interference phenomenon caused by computer network instability computer will prompt the Internet cables are unplugged.

Solution:

Call local network operators to send someone to detect the problem by accessing the network cable without interference.

Reason two the ARP virus causes the LAN network to lose the packet phenomenon to cause the computer prompt cable to be pulled out seriously.

Solution:

Find a professional ARP interception software to intercept, the application of network card binding technology to solve the LAN caused by ARP packet loss phenomenon.

Reason three wire or cable at both ends of the crystal head aging, oxidation phenomenon or network cable quality problems and cable production problems caused by computer cable was unplugged.

Solution:

① Network cable Aging Problem:

Daily use of long network cable will appear aging phenomenon, such cases often make the data transmission is not normal, such a phenomenon on the selection of a good number of network cable can be used to solve the problem.

② Crystal Head oxidation problem:

For the more humid place crystal head is prone to oxidation phenomenon, this phenomenon will also cause network data transmission is not normal, or even network, so can only replace the cable and new crystal head for use.

③ Cable Quality problem:

Poor quality network cable work on its internal general use of iron wire inferior quality prone to break phenomenon, such a phenomenon will cause network instability or network interruption general purchase cable to buy more well-known brand cable use can.

④ Cable Production problem:

Crystal Head and wire when the production of the card if there is no good situation will often appear a lot of trouble network problems, so we in the process of making the network cable must use the Crystal Head card good network cable do not put the line inside the wire leakage in the crystal head outside to do a good job of the signal after the test is normal.

Cause four network access provider server problem caused network cable was unplugged.

Solution:

This phenomenon occurs only when Internet access providers come or we can call to urge them to resolve.

Reason five uses the router or "the cat" to appear the network cable is unplugged phenomenon.

Solution:

If this occurs during router usage, refer to reason 1234 listed above to resolve the problem, which already includes the router phenomenon. (Note: The premise is that your route is not bad in the case of "cat" instability problems please see the "Cat" on the network light shining is normal if the situation is not normal, you can call to find an access provider to solve the problem, you can also buy a "cat" put on the test.

Reason six NIC problem caused network cable to be unplugged.

Solution:

Network network card is also the most critical of a small hardware, networks have many problems with network outages please look down.

① NIC driver problem:

If the NIC driver is not installed correctly, there will be network interruption or instability, and we can download the old driver uninstall and reload the newer model-compliant driver installation.

② network card itself reason:

Check the NIC on whether there is a drum bulge phenomenon, if there is a bulge phenomenon we can replace the NIC to solve the problem.

③ Network card Contact Bad problem:

Network card contact is generally a part of the network card gold finger oxidation caused, if the oxidation with a rubber lightly inserted a few can solve the problem.

④ NIC Network interface problem:

Network card if the network interface damage also does not need to repair, now the network card cheaper directly to change a piece.

Summary: In fact, network problems are also very good troubleshooting is generally the case. If there are problems with the network the above methods can not be resolved, please follow the following aspects of troubleshooting, I hope to be able to solve the problem for you in time.

The reason that the computer drops the line is various, need to go to the investigation carefully.

First, the network supply room failure.

Second, the network line problem.

1, from the Bureau end to the user door between the line is too long, poor quality of the line, the line has winding, too long lines, lap joints too much.

2, there is a telephone extension does not connect the separator and directly lap on the line.

3, the line from some with strong magnetic field of home appliances too near, such as high-power audio, rectifier, high-power motor and so on.

4, weather factors, such as rainy days, air humidity led to joint oxidation, such as thunder and lightning, resulting in the line magnetic field changes caused by induced currents.

5, the network use is limited or use peak broadband cut-off.

Third, the indoor network equipment problem.

1, the network line contact is bad, the big part is the plug loose, individual is broken off, will all the connection plug in, especially the network card with the motherboard, network network cable crystal Head connection, with a pin finishing the network card port of the spring bar, or to make a bit of crystal head, at the same time to the network card (including integrated network card) dust.

2, network hardware quality problems, such as, double glue line, crystal Head, separator, cat, router, network card.

3, attention to separators, cats, routers, heat dissipation. Turn off the cat and the router power supply 20 points and then connected.

Iv. computer problems.

1, reduce the transmission rate of 10/100m network card

Right-click My Computer-Properties-hardware-Device Manager-expand network Adapters-right-click the Nic-Properties-Advanced-in the properties column, select connection speed and Duplex mode. Set to "10Mbps full duplex" in the Value column-"Performance optimization", set to "open"-OK.

2, integrated network card if the work out of the instability, you can change a separate network card, update the driver.
