Why is the network port light not on?

1. If the network cable is plugged into the computer's Internet port and the light does not light up, it may be due to poor contact.

2. If you have plugged the Internet cable into the WAN port of the router, but the WAN port indicator still does not light up. At this time, please check the following aspects: Check whether the network cable is plugged in properly and whether there is any problem with the network cable.

3. If you confirm that the network cable is not loose and has been plugged in; however, the WAN port indicator light still does not light up. Then, there may be a problem with the network cable plugged into the router's WAN port, causing the router's WAN port to not detect signals, so the router's WAN port indicator light does not light up.

4. It is recommended that you try to use better quality network cables, plug the network cable into the computer, and the computer can access the Internet normally. However, when plugged into the WAN port of the router, the WAN port indicator light does not light up.

5. If your router’s WAN port is connected to the home broadband network cable provided by the operator. The other end of this broadband network cable is connected to a switch; if there is a problem with the switch, the indicator light of your router's WAN port will not light up.

6. To connect to the LAN, a network cable is essential. There are three main types of network cables commonly used in local area networks: twisted pair, coaxial cable, and optical cable. Twisted pair is a data transmission line composed of many pairs of wires. Its characteristic is that it is cheap, so it is widely used, such as our common telephone lines. It is used to connect to the RJ45 crystal head. It has two types: STP and UTP. The one we commonly use is UTP.

7. Coaxial cable is a cable made of layers of insulated wires wrapped around a central copper conductor. It is characterized by good anti-interference ability, stable data transmission, and low price. It is also widely used, such as closed-circuit television lines, etc. Thin coaxial cables generally sell for a few yuan per meter in the market, which is not too expensive. Coaxial cables are used to connect to BNC connectors. Coaxial cables sold on the market are generally finished products that have been connected to BNC connectors. You can choose them directly.
