A cable internet connection is preferable because the data transfer speed is higher and the overall signal quality is higher. But due to the presence of a large number of physical components that are located on a sufficiently large space, there is a risk of damage to the wired connections. Therefore, the USB modem is considered a more reliable source, despite the lower connection speed.
Possible reasons
But a large number of people use cable connections. 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 needs to be done? Suggested causes may include:
- Spontaneous disconnection of a network cable.
- Damage.
- Network card failure .
- Missing or damaged network driver.
- Incorrect computer settings.
Wired Issues
So, the computer does not see the network cable. What's the matter? The wire itself, as well as connectors, 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, installation workers have been distinguished by obvious negligence in carrying out their work. They lay the cable without additional protection and in places that are easily accessible. Any bully who has a tendency to vandalism, who passes by, will definitely want to pull the hanging wire and with this action deprive access to the Network the whole floor.
Therefore, first of all, you need to control the entire installation process of wired Internet. It is necessary to require engineers to comply with all standards.
The next subtle point, because of which the network does not see the network cable, is its wiring inside the apartment. If there are children, as well as pets, there is always a danger. It is desirable to place wires in hard-to-reach places. Dogs and cats are very fond of biting, biting various ropes. And electric fields for some reason are very attractive for pets.
- It is necessary to carefully trace the network cable in all visible areas. If damage is found, it is best to replace the entire piece at once.
- It is necessary to check whether the plug has dropped out of the socket. It is necessary to remove the connector and insert it again. In this case, a characteristic click should be heard.
- Carefully inspect all pins on the connector. If you see that there are bent or broken off, the connector requires replacement.
The final test of cable functionality is to connect another computer. If his network board does not see the cable, then the fault is exactly in it. Otherwise, you need to deal with the PC.
PC problems
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 previously the connection worked fine, then you can roll back the operating system to a previous state, which can eliminate the problem. Very often, the Internet stops working due to very active surfing when suspicious sites are visited, and an antivirus is not installed.
In the event that the rollback did not help and the network does not see the network cable, you need to open the connection interface and conduct connection diagnostics. It happens that the Network speed limit is incorrectly set. You need to check these settings.
Driver problem
These system programs are another common problem that leads to disruptions to the Web. Where to get drivers and how to install? Their complete set 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 from the search for the appropriate 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 reinstalling, you will need to reinstall all the programs. Usually it is worth resorting to reinstalling the operating system when it starts to work poorly, and the computer often freezes and slows down.
OS update
There is another solution that is less dramatic - the launch of an automatic system update. But if the computer does not have the latest version of the OS installed, there may no longer be updates for it due to the termination of support. The same situation with pirated copies. When you try to update them, it is likely that the system will be completely destroyed.
The necessary drivers can be downloaded from the Internet. This method is suitable if there are other devices at home that do not experience connection problems. You must 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 wizard of the operating system.
Summary
Why doesn’t my computer or laptop see the network cable? The main reasons are listed. If you find the right one, then you can cope with the problem on your own, without having rich experience. If all else fails, it remains only to take the equipment to a service center, where experienced wizards will help solve the problem with the network connection.
