My laptop is not connected to the Internet? It always shows that the network cable is not plugged in

You see that there is no light on in the plug-in place after plugging in the wire, if it does not indicate that it is a hardware problem.

If only your machine can't work, it may be a problem with the network card.

It should be a problem with the interface, you check whether the interface is plugged in steadily, it is best to unplug it and plug it in again. If that doesn't solve the problem, try a different crystal head. The crystal head is not done well, or the quality of the network cable is not good, or the switch and network card are not in good contact with the crystal header.

As long as both ends of the network cable are connected to a working network port, this problem will not occur1. It could be that the port on the switch side is unplugged.

2。The port on the switch side is closed.

3。Your network port or the network port on the switch side is broken.

If the IP address is blocked, it must communicate with the switch before you can connect to the gateway, but the local connection will not be disconnected.

If you can switch the interface, it is a problem with the interface on the switch side.

1. Restore motherboard BIOS to factory settings.

2. Reinstall the system.

3. Install the official driver.

4. Make sure that the network cable, routing and other related equipment are normal.

5. Make sure the network is unobstructed.

6. Configure a fixed IP address.

7. If it doesn't work, it's ready to be repaired.

You need to reset the network connection, because you were originally at home, but now you have changed places, some need to be reset, and some computer settings, any network cable can be used, and you can change anywhere.

Check whether the properties of the local connection have been changed. Local Connection—Properties—General—Configuration—Advanced—Properties, and compare the setting of the property value with the neighboring computer. This is mainly the speed and duplex, MAC value and other settings.

Problems with network cables. It is also possible that the crystal head of the network cable interface is faulty, and the local connection may show "The network cable is not plugged in". The solution is to plug this network cable into a computer that can connect to the Internet, if it can be used, it means that the network cable is good, then eliminate the possibility of network cable failure.

If you can't, try a good cable.

There is a virus in the computer. Use anti-virus software to kill viruses in all aspects. Then try again.

The interface of the NIC (card slot) is faulty. If the solder joints fall off or there is too much dust in the card slot of the access network cable, the network connection may also be affected. This one is going to be repaired.

Problems with the system. A system failure can also cause the local connection to become unavailable. Of course, this requires a reinstallation of the system. As long as it is not a hardware problem, the vast majority of network failures can be solved by reinstalling the system.

When surfing the Internet, it is recommended to reinsert the network card or reinstall the driver and try again, and pay attention to whether the network cable and network card interface are normal, you can try to change the network cable.
