This network cable is really strange-the notebook is available, the desktop is not available (the other end can press the crystal head)

Cause:

My colleagues reported that the Local Area Network could not be mounted. After reading the past, they found that the prompt "the network cable is not plugged in". I suspect that it is not plugged in, plug in, restart, and reinstall the NIC Driver.

My colleague reported that the network cable could be connected to the LAN using a laptop. After trying two laptops, I could.

Therefore, check whether the NIC is loose. After the NIC is opened, it is found that there is no obvious burning, and the bayonet is not obviously distorted or bent.

Connect the computer to the network cable of the adjacent station to connect to the LAN normally.

Repeat the crystal head with a try, but the problem persists.

My colleague's mind is shining brightly and switching the network cables that are not used in the adjacent stations to solve the pressing problem.

Process:

However, it is a pity.

After a while, I did not find any good solutions.

However, it would be better if you could use more other desktops for testing (it may be that the notebook has a better redundancy check mechanism)

At around three o'clock P.M., my mind was groose and I decided to try more desktops.

Insert the network cable to the other two machines. One is connected when the network is disconnected, and the other simply keeps "the network cable is not plugged in ".

The network cable is identified as abnormal.

View the crystal head at the other end, and find that there is a clip spring that has been lifted, so reset the suppress crystal head. Then the test is normal.

Conclusion:

Later, my colleague reported that after I left, he squashed three more times, but he was not able to use the notebook for the last time. So you can use the plug-in at the other end.

Even so, the conclusion is still not good.

It may be that the network cable is often kicked and mixed, leading to loose, but the laptop has a high redundancy mechanism (more stringent protocols are used), so it can be used.

As it is on the verge of crisis, the above is the case.

My colleagues are smart. They first use the network cable of the adjacent station to replace it, and then plug it in at the other end, which is a sign of a bright brain. It seems that my mind is not good. Watch more in the future.

Network maintenance is not easy.
