Why does not the network cable see the network cable

Connecting the Internet using a cable is more preferable because the data rate is higher and the overall signal quality is higher. But because of the large number of physical components that are located on a sufficiently large-scale space, there is a risk of damage to the wiring. Therefore, USB-modem is considered a more reliable source, despite the lower connection speed.

Possible reasons

But the cable connection is used by a large number of people. And yesterday there was high-speed access, and now the network does not see the network cable. Who is to blame for this and what should be done? Among the suggested reasons may be:

• Unintentional disconnection of the network cable.
• Damage.
• Network card failure .
• No or damaged network driver.
• Incorrect computer settings.

Problems with wired connection

So, the computer does not see the network cable. What's the matter? The wire itself, as well as the connector connectors, are the weakest link. As a rule, part of the wire is located in the apartment itself, and the rest - on the stairwell, in the entrance.

Recently, the assembly workers differ in their apparent negligence in the performance of their work. They lay the cable without additional protection and in places that are easily accessible. Any hooligan who has a tendency to vandalism, which passes by, will necessarily want to draw for the hanging wire and by this action to deprive the whole web of access to the Net.

Therefore, in the first place, you need to monitor the entire process of installing a wired Internet. It is necessary to require engineers to comply with all standards.

The next subtle moment, due to which the network cable does not see the network cable, is its wiring inside the apartment. If there are children in it, as well as pets, there is always danger. It is desirable to place the wires in hard-to-reach places. Dogs and cats are very fond of biting, gnawing different ropes. And electric fields for some reason for pets are very attractive.

1. It is necessary to closely monitor the network wire in all visible areas. If damage is found, it is better to replace the whole piece at once.
2. It is necessary to check whether the plug has fallen out of the socket. It is necessary to remove the connector and insert it again. In this case, you should hear a characteristic click.
3. It is necessary to inspect all contacts of the connector carefully. If you see that there are bent or broken, the connector needs replacement.

The final test of the cable is the connection of another computer. If his network card does not see the cable, then the fault is exactly in it. Otherwise, you need to understand the PC.

Problems with a personal computer

Presumably, the problem lies either in the system unit or in the operating system. The most common reason that a computer or laptop does not see the network cable is a system configuration failure. You need to go to the "Control Panel" and change them to the correct ones. You can find out the settings from the provider.

If the connection used to work normally, then you can roll back the operating system to the previous state, which can save the problem. Very often the Internet stops working because of very active surfing, when suspicious sites are visited, and the antivirus is not installed.

In the event that the rollback did not help and the network cable does not see the network cable, you need to open the connection interface and conduct connection diagnostics. It happens that the maximum speed of the Network is set incorrectly. You need to check these settings.

Problem with the driver

These system programs are another common problem that leads to disruptions in the work of the Network. Where are drivers taken and how to install correctly? A complete set of them can be found on the disk from the motherboard or in special collections of drivers. If the network does not see the network cable, and the user does not want to suffer with the search for a suitable driver, you can simply reinstall the operating system. After that, all the settings will be in order, and the drivers will install themselves.

The main obstacle to using this method is the inevitable loss of all user settings. After reinstallation, you will need to install all the programs again. Usually, you should resort to reinstalling the operating system when it starts to work badly, and the computer often hangs, slows down.

OS Update

There is one more solution, which is less radical, is the launch of an automatic system update. But if the computer is not installed the latest version of the OS, updates for it may no longer be due to the termination of support. The same situation with pirated copies. When trying to update them, the probability of complete destruction of the system is great.

You can download the necessary drivers from the Internet. This method is suitable if there are other devices at home that do not experience connection problems. You need to go to the official website of the equipment manufacturer, find the right model and download the software. After that, you can install the driver using the operating system wizard.

Results

Why can not I see a network cable from a computer or laptop? The main reasons are listed. If you find the right one, you can deal with the problem on your own, without having a rich experience. If nothing helps, then it only remains to take the technician to the service center, where experienced masters will help to solve the problem with the network connection.
