The computer network cable interface light is not on, so you can't connect to the Internet. What is the reason?

First of all, I'm a rookie, so I'll talk about the possible reasons why the green light is not on! 1. Your network card is broken. 2. Your crystal head is not plugged in properly. 3. There is something wrong with the line. Your network cable is incorrectly connected to other devices (cats, routers, etc.). Solution steps: 1. Check whether all your sockets are connected wrongly (and firmly). 2. Move your box to your relatives, neighbors and classmates (people with computers) nearby to see if it still doesn't work after replacing your host. If it is 1. Your home interface is wrong. There is something wrong with your home phone. I suggest calling Telecom or China Unicom to fix it for you. If nothing works, it is estimated that there is something wrong with your network card. Then carry it to the place where the computer is repaired.
