Will the network card break? What s the phenomenon when the laptop network card is broken?

As follows:1If the quality is not in question, the normal use period of the piece is 3-5 years.

If the quality is not good. It's going to break a little faster.

If there is a lot of dust and the network cable is unplugged and unplugged frequently, it will break down a little faster.

2.If it is left open for 24 hours, according to common sense, the life of the network card will age a little faster. Because every electronic component has its lifespan.

It's the same with machines, if you work for a long time, you will definitely get tired quickly. It also breaks down quickly. Plus the quality is not up to par.

That's going to break faster.

There is also one, when there is thunder, turn off the router switch of the "cat". The computer should also be turned off the power, if it is only turned off, the power supply of the router switch "cat" is not turned off, and it is useless when there is thunder, and it will also burn the network card.

I've seen a lot of computers have problems with their network cards. That's why there are so many independent network cards on the market**.

Thunder has to be pulled, and the voltage is high to burn, generally not.

As long as it doesn't thunder, it shouldn't break in general.

It will burn out, don't rely too much on it, and the probability of going bad depends on the quality of the network card (that is, the price, the quality problem).

Check to see if your network cable is connected.

Check on your cat.

The network card generally does not break.

You can also double-click the network connection to see how the network card is working.

Even if it's really broken, it's easy to do.

It is to open the chassis and insert the network card into the PCI white slot below.

Turn on the machine after installation.

The system detects the new hardware and puts it into the drive of the network card.

It's OK to finish as prompted by the system.

It's simple. 15 bucks for a new one.

If it doesn't work yet.

Just change the cat handlebar.

Dear, hello, I'm glad to answer for you, what is the phenomenon of a broken laptop network card, and the answer is as follows; 1. If the network card is broken, then the network card may not be visible in the device manager - network adapter, and there is no unknown device, which means that the computer cannot detect the network card. 2. Also in the "Device Manager" there is "Network Adapter", and there is also "Realtek RTL8139......"Wait for a row in English, but in "Realtek RTL8139......"There's an exclamation point on it. And no matter how you install the driver, reinstall the system, etc., this exclamation mark cannot disappear, that is to say, the network card cannot work normally.

3. When plugging in the network cable, the lower right corner of the computer always prompts "the network cable is not plugged in". In the case of plugging and unplugging the network cable or replacing a new network cable, when the network cable and network fault are eliminated, the computer still prompts "the network cable is not plugged in", and the network card can also be concluded at this time. 4. Under normal circumstances, the indicator light will be on after the network card and network cable are connected, green means that it has been connected, if the network cable is plugged in, the network card light has not been lit, and the network cable has been replaced, the router and other tests are still not on, then it is also possible that the network card is damaged.

5. The NIC only sends packets, and the NIC only sends packets, but does not receive packets. In this case, if you are troubleshooting the network itself, computer system problems, etc., it also belongs to the network card damage. Hope it helps you and I wish you a happy life.
