What should I do if the computer network cable interface light is not lit?

The computer's network cable interface light is not bright. If you encounter such problems, there are generally five cases depending on your own experience.

The first is that your network cable is not ready or not connected.

The second is that you disable the local connection.

The third is that your network card driver is not installed.

The fourth is that your network card has a problem.

The fifth thing is that your computer cat is broken.

Telecom cat, take my telecom cat as an example, as shown in the figure, POWER is the power indicator light, and the indicator light is on.

RUN is the running light, flashing and flashing means normal. DSL is the telephone line interface. It always stands for normal. If it flashes or does not light, it means the phone line is not connected or ADSL is not normal.

LAN1-4 stands for NIC interface, and always lights up to indicate normal. ITV is a network TV interface, WLAN is a wireless interface number, WPS is wireless authentication, and USB is an external USB device.

When we encounter such problems with the computer's network cable interface light, first look at the network cable is not connected, after the ADSL network cable is dialed down and plugged in again, then Put the network cable behind the computer network card and put it back again.

Check if the indicator is normal.

If you can't, change the network cable.
