What is the reason why the plug of the network cable does not flash, why does the light not flash af

The plugs at both ends do not blink to indicate that the physical link has been established, but the data channel should be faulty, resulting in the data stream not being sent to the peer, which is common in the transmission of data signals One of the cores is in poor contact or the port is faulty.

There are generally two indicators for the network cable port: green light and yellow light (there are also orange red ones) Green light: indicates the hardware connection status of the network cable, detects whether the establishment of the physical link of the equipment and the network cable at both ends of the network cable is successful, establishes the connection normally, and the green light is always on.

If it is flashing or not lit, it means that there is a problem with the physical connection, and the fault occurs at the network cable or the ports at both ends.

Yellow light: When there is data stream transmission, the yellow light flashes, the larger the data stream, the faster the flashing, and the yellow light does not flash to a solid state without data transmission (but because after the network cable is connected, the devices at both ends will send a handshake packet even if there is no data transmission, so the yellow light will definitely flash for data transmission).

It is recommended that you see if it is the reason for the driver It is better to reinstall the system. After ruling out the system problem, see if the interface is oxidized, and wipe it with a cotton swab dipped in alcohol. Eliminate these can basically determine that there is a problem with the interface or motherboard chip, and take it to the repair place to see.

Thank you.

Check that the contact strip of the socket is good and make sure that the wire ends are in good contact.

Generally, there are two LED indicators, the green light represents the connection indicator link, and the connection indicator light is on to indicate that the network card and the network connection are in good condition (some onboard network cards only work at 100m, this light is on). The red light indicates that the signal transmission indicator stool is acting, and the signal transmission indicator flashes to indicate that the NIC is transmitting data.

When the network traffic is large, the flashing frequency of the indicator will increase; When the traffic decreases, the frequency of the flashing light will decrease. Therefore, the light at the interface of the crystal head of the network cable has a non-stop flashing, and a non-flashing means that the positive network card is transmitting data, the transmission is normal, and the network connection signal is producing.

Summary. There are mainly the following reasons for you to check.

1. Check whether the network cable is broken or broken, whether it is good, if there is no broken skin, please unplug it and plug it again.

2. The local connection is disabled.

If you're sure that there's no problem with the network cable, you can right-click on your desktop neighbor and click Properties. If you see the local link grayed out, it means that the local link is disabled, you can right-click on the local link and click Enable. This will allow your local link to be enabled.

3. Check if the network card driver is installed.

4. There is a problem with the network card.

If you open the online neighbor property and find that the local link is marked with an exclamation mark, you can turn off the host and power off. Dial the NIC and plug it in again.

5.Check if there is any problem with your optical modem and whether there is any network.

Why doesn't the light flash when the computer is plugged into the internet cable?

What is the problem?

It's just that the network cable is not plugged in.

Why doesn't the light flash when the computer is plugged into the internet cable?

Why doesn't the light flash when the computer is plugged into the internet cable? Hello pro reason 1: the computer's network cable interface light is not lit.

There will be several situations, the first is that the network cable is not done or connected. Check whether the network cable is broken or broken, if not, please unplug it and plug it in again. Reason 2:

Local connection is disabled. If you're sure that there's no problem with the network cable, you can right-click on your desktop neighbor and click Properties. If you see that the local link is grayed out, it means that the local link is disabled, you can right-click the local link and click Enable...

Cause 4: There is a problem with the network card.

Why doesn't the light flash when the computer is plugged into the internet cable?

Why doesn't the light flash when the computer is plugged into the internet cable? Hello, the pro-network cable interface light does not light up may be because the network cable is not done well or not connected. You can replug the network cable again, or check whether the network cable is broken or broken.

If it's not a problem with the network cable, turn on your computer and open the Network Configurator. On the Network Configurator page, check whether Ethernet is enabled. You can also open the NIC Drivers page to check whether the NIC driver is installed or whether it is running properly.

1. Computer network cable interface.

It was loose and not well installed. After connecting the network cable interface first, if it is yellow.

If you flash, you can surf the Internet normally.

2. If the source state yellow light does not flash, it may also be a problem with the network card. At this time, the network card can be replaced, if the network card can be used after replacement, it is a problem with the network hail oak source card.

3. There may be a problem with the crystal head of the network cable, and it is like blind to re-play the crystal head of the network cable.
