Local connectivity is related to the interconnection of the LAN and the local connection to the Internet. If there is a problem with the local connection, then both the LAN and the Internet will not be accessible. The following will introduce the reasons and solutions for network cables not being plugged in properly.
There are many problems with local connections, one of which is that it prompts "the network cable is not plugged in", and you may also encounter this situation, after turning on, the local connection sometimes connects normally, and sometimes there is a situation of "the network cable is not plugged in properly", in short, it will be connected, and it will not be connected for a while, and there will always be an intermittent network connection state, so that the network is not normal.
Taking the problem literally, it is mostly due to a problem with the physical connection of the network.
The network cable is not plugged in properly Reason 1: The problem of the crystal head
If there is a problem with the crystal head, it may lead to poor contact of the crystal head connected to the motherboard, looseness, etc.
You can pluck the crystal head off first, and then put it on, pay attention, you can hear a click when you put it up, which means that it is stable. If the problem is still stable, then it is estimated that there is a problem with the thread in the crystal head, and at this time, you have to remake a new crystal head.
Of course, the problem may not be entirely in the place where the crystal head is connected to the motherboard, it may be in the place where the switch or router is connected, and you have to use the same method to troubleshoot.
Reason 2: network card driver
Don't think that only hardware problems will also have problems with software drivers.
You can troubleshoot whether it is a driver problem by following the following methods.
Right-click on My Computer, find "Manage", and a dialog box will pop up.
In the dialog box, find "Device Manager", then look at the list to the right of it, select "Network adapters" and see if its icon is a yellow question mark.
If so, the driver has not been installed correctly, and you need to reinstall the NIC driver to fix the problem.
Reason 3: There is a problem with the router
If there is a problem with the router, if it is a soft setting, then please check whether the router has set up the use of a certain IP, reset it, and then restart the router.
Also, there is a small hole in the router, you use a wire or a small object, insert it into it, and wipe it continuously, the route will reset and start, or it may solve the problem.
Of course, if it is a hardware problem with the router itself, you have to change the route, because according to some netizens, after the router is struck by lightning, the local connection will appear with a prompt of "the network cable is not plugged in properly".
The network cable is not plugged in properly Reason 4: Wireless network problems
If your network uses a wireless network, the problem may be with the router.
The reason may be whether the route itself is faulty, and at the same time, whether there is signal interference nearby, etc.
Reason 5: Don't forget the ARP virus
If you encounter an ARP virus on your computer, this will also happen.
You can try using antivirus software to check for local viruses and see if that can eliminate the problem.
Or, turn on the 360ARP firewall and let it provide firewall functionality to your network to protect your network.
Reason 6: IP setting or acquisition
Originally, the IP address was set locally, but the local connection cannot use the IP, and it will be in the state of obtaining the network address for a long time, which may lead to the prompt in this article.
In this regard, you need to first make sure that the IP is set correctly, and you can also disable local connections before enabling them, which may solve this problem.
The above is the reason and solution for the network cable not to be plugged in for you, I hope it can help you.
