The laptop does not see the wan cable. The computer does not see the Internet cable, what should I do?


Wired connection Internet is preferable due to more high speed data transmission and overall signal quality. However, the presence large quantity physical components located over a fairly large space creates risks of damage cable connections. In this regard, a USB modem seems to be a more reliable source, although a slower solution for providing home Internet.

So, just yesterday you were enjoying the video high resolution, today LAN card can't see the cable? Who is to blame and most importantly, what to do? The following list can be compiled as possible reasons.

  • Damage to the network cable.
  • The cable disconnected spontaneously.
  • The network card is faulty.
  • Incorrect computer settings.
  • Network card drivers are missing or damaged.

Cable connection problems

The weakest link is the cable itself and the connectors. Usually, part of the cable is located inside the apartment, the rest is in the entrance, on the staircase.

IN last years Installers from the service departments of Internet providers show obvious negligence in the performance of their duties. Cables are laid without additional protection by casings and in easily accessible places. Any hooligan with a penchant for vandalism passing by experiences an irresistible desire to pull the rope hanging from above and immediately deprive the entire floor of access to the Internet.

Therefore, first of all, be sure to control the entire installation process cable internet, require the provider’s employees to carry out all operations in accordance with GOST and in a protective manner.

The next subtle point is the internal cable wiring. If children and pets live in the apartment, a situation is created increased danger. It is advisable to place wires in inaccessible places. Cats and dogs simply love to gnaw, bite and tear all sorts of strings. At the same time, electric fields are for some reason very attractive to pets.

  1. Follow carefully network cable on all visible areas of the gasket. If damage is detected, it is best to immediately replace the entire unusable piece.
  2. Check to see if the plugs have fallen out of the socket. Remove the connector and insert again. You should hear a closed lock click.
  3. Carefully inspect the connector contacts. If broken or bent contacts are visible, the connector must be replaced.

You can finally check the functionality of the network cable by connecting another computer. If the Internet appears, it means that everything is in order with the cables and you need to look for faults in the computer.

Computer problems

It is assumed that the problem is in the system unit or operating system of the computer. Don't rush to open it right away system unit. Most common reason– broken Windows settings.

Go to Control Panel\All Control Panel Items\Network and Sharing Center and shared access and change the settings

If the Internet worked normally before, we can assume that the operating system was rolled back to one of previous states may solve the problem. Often the Internet stops working after excessively active surfing on the Internet, especially when visiting suspicious sites and without an antivirus installed.

If the rollback does not help, open the Internet connection interface and diagnose the network connection. Check if the settings are correct network connection. Sometimes the reason that the network card does not see the cable is that the Internet speed limit is set incorrectly. Check and adjust according to instructions.

If you need to indicate Internet settings in specific numbers, you need to contact your Internet provider and get all the necessary information for a specific network connection.

Driver problem

Network card drivers are another weak point, often leading to problems with Internet reception. Where can I get these programs and how to install them correctly? Full set necessary drivers located on the Windows operating system distribution disk.

Sometimes it makes sense not to bother searching specific programs, and reinstall all at once operating system Windows. In this case, all computer settings and settings will return to factory settings, and all necessary drivers will be installed again.

The main obstacle to the use of this method is the almost inevitable loss of all custom settings computer and the need to spend time on reinstallation all work applications. Usually, to reinstalling Windows resorted to in cases where the system itself begins to not work very well, slows down, glitches, and often collapses.

You can try less cardinal decision– run automatic update systems. However, if you don't have the most latest version Windows technical support may have already been repainted and there is no update. The situation is approximately the same with the left. Windows versions. An attempt to update them will inevitably lead to the destruction of the installed system.

You can download the necessary drivers from the Internet. This path is suitable if you have other computers at home with working Internet. Go to the official website of the network card manufacturer, find your model and find out which divers you need. Download them and save them to a flash drive or DVD. After this, you can go to the Computer Control Panel and install drivers using the Wizard.

Conclusion. If you still fail to match the network cable with the card, and the Internet still does not turn on, all you have to do is turn to specialists for help.

In modern life, the presence of a computer at home or at work automatically means the presence of a network on it, either local or with Internet access. Using a network card, your Calculating machine allows you to get information, communicate, and sometimes even work or play. Naturally, when the network disappears for some reason, we feel as if cut off from the vast sea of ​​​​opportunities that it gave us.

This happened to me too. I turn on the computer, the system is loading - and what do I see? A message about an unconnected network cable in the middle of the screen. But I was just going to check my email and read the latest news, and we should also not forget that in order to comfortably watch movies or work, you also need a computer. Why such a misfortune with the cable? Why doesn't the network card see the cable? Windows 7 was recently installed on the computer. Moreover, just yesterday everything was working perfectly - and yet the problem still exists and needs to be fixed.

Cable check

First of all, I checked the cable itself - what if it really isn’t connected? Sometimes this happens if it is accidentally touched or pulled out while moving a laptop or computer. To check, just pull the cable out to the end and insert it back. There should be a slight click, indicating that the cable is in place. Is the problem still there? We continue our further search for a solution.

We take out the cable again and carefully inspect it. It's worth starting with the connector itself - it can be physically damaged, which will be noticeable by cracks on the connector or bent and missing contacts. When positive result search, the connector should be replaced. If everything is in order, the inspection smoothly proceeds directly to the cable. The main attention should be paid to kinks and breaks in the braid. If damage is detected, the cable is replaced, completely or partially. In principle, the not too high price allows you to avoid wasting time on replacing part of it. It’s easier to do this with the entire cable up to its nearest twist, the distance to which inside an apartment or office rarely exceeds 10 m.

Checking your computer

After checking for physical damage I regretfully noted the fact that the network card still does not see the cable on the laptop. Which means it’s not the cable at all.

Is it possible that the problem is hidden in the computer? Here the check is quite simple, although this will require another device with a network card. We connect the cable to it and see if the Internet appears. If yes, then you should look for the reason in the drivers or settings of your network card. However, there may also be an option with damage or malfunction of the card, which in this case will simply have to be replaced.

However, do not rush to get rid of the network card until you check its settings. For some reason, they could go wrong on their own - to fix such a problem, you should contact your Internet provider and check with them exactly how your settings should be. And some similar devices that support data transfer at a speed of 1 Gbit/s occasionally experience problems that require setting the operating mode settings to no more than 100 Mbit/s.

And it happens that the network card does not see the Internet cable and “swears”, sending you messages about non-connection when its control programs - drivers - go wrong and stop working correctly. Reinstalling drivers is possible, for example, with system disk supplied with the equipment or can also be configured on a computer. If such options do not suit you, then you will have to download programs from the Internet, however, on another computer, because yours does not yet see the network. For comfortable work in the Internet .

conclusions

Carrying out all the checks described above will not be difficult for any person more or less familiar with a computer. However, if any of them causes you difficulties or none of the checks helped, you will have to contact a computer service center.

There are often situations when, after connecting a computer or laptop to the Internet using a network cable, the error “Network cable is not connected” appears. This is most likely not even an error, but simply the status of the network adapter, which can be observed in network connections.

It turns out that the computer does not respond to the connection in any way; the network cable is not connected, although it is connected to the computer and inserted into the network card connector. Icon on the notification panel with a red cross. Well, the Internet, of course, doesn’t work. This is what it looks like:

And most importantly, the cable is connected. From a router, modem, or directly from the provider’s equipment. This error can appear on both a PC and a laptop. It also doesn't matter which Windows is installed on your computer. Only in Windows 10 will the message “Network cable not connected” appear next to the “Ethernet” adapter, and in Windows 7 – next to “Connect via local network". And in Windows XP, a pop-up window with this error still appears if you hover your mouse over the connection icon. This also often happens.

The same goes for the connection method. Some people have a network cable coming directly from their provider (for example, Rostelecom), and for some via a modem, Wi-Fi router, or terminal.

What could be the problem?

There can be many reasons. We list the main ones:

  • The network cable is incorrectly or not fully connected.
  • The network cable is damaged. The contacts in the connector may have come loose (into which the network cable itself is crimped).
  • Hardware problems with the router, modem, provider equipment. Or the network card itself in your laptop or PC has broken down.
  • Problems with the network card settings. Most often, it cannot automatically determine the speed and duplex. I'll tell you about this in more detail.
  • There are some problems with the network card driver.
  • Viruses, firewalls, some programs. Yes, yes, they can also cause the “Network cable is not connected” error to appear.

How to find out the reason and what to do first?

  • First, restart your computer, modem, router (if you have one).
  • Disconnect the network cable and connect again. Also check the connection on the router (if the Internet is connected through it). Connect the cable to another LAN port. Pay attention to whether the LAN indicator on the router lights up after connecting the cable. You can see the instructions: .
  • If possible, connect via a different cable.
  • You can lightly move the network cable where it enters the connector. And at this moment look at the status of the network adapter on the computer. Perhaps the contacts are leaving there, and this way we can find out.
  • If you have another PC or laptop, try connecting it. This way we can find out what's going on.
  • If the Internet goes through a router, then try connecting the cable from the provider directly to the computer.

I would divide the solutions into software and hardware.

The network cable is not connected, although it is connected: solutions to the problem

1 I would try removing the network card from Device Manager. After a reboot it should recover automatically. Go to Device Manager (the easiest way to find it is through a search, or press the Win + R key combination and run the command devmgmt.msc).

Open the "network adapters" tab and find your network card. Depending on the manufacturer and driver, the name may be different. The name may contain "LAN". For example, on my laptop it is “Realtek PCIe GBE Family Controller”. By the way, pay attention to whether there is a yellow icon. Click on it right click mouse and select "Remove device".

We confirm the deletion and restart the computer. Perhaps after a reboot everything will work and the computer will see the connected network cable.

2 Check the speed and duplex detection settings. In Device Manager, right-click on the network card (as I showed above) and select "Properties".

Next, go to the “Advanced” tab. In the list, find and select "Spread&Duplex". And in the drop-down menu on the left, set the value to "Auto Negotiation". But if you initially had it installed there this option, then try setting a different value. For example: "100 Mbps Full Duplex". You can also try different variants. Don't forget to click Ok and restart your computer.

It just often happens that the network card cannot automatically detect speed and duplex.

3 Network card driver. You need to try reinstalling it. Download the driver from the website of the manufacturer of the card itself (LAN), laptop, or motherboard your computer and start the installation. You can look at the article on this topic:.

Other reasons why the computer does not respond to the connection of the network cable

1 Network card failure. However, in this case, you most likely will not see it in the device manager. But it happens in different ways. To find out, you need to connect another cable to it. Connect to another router or provider. Or connect other devices to the same cable. 2 Problems with the provider. For example: an employee of the provider was connecting the Internet to another subscriber, and accidentally disconnected your cable from the equipment, or the cable was broken somewhere in the entrance. Or maybe someone cut it on purpose. In such cases, the message “Network cable is not connected” will appear. You need to contact your provider's support. Just before doing this, it would be good to make sure that the problem is not in the network card of your computer. It also often happens that the contacts on the connector into which the network cable from the provider is crimped are lost. You just need to do it again and correctly. Or call the experts. 3 Problem with the router. May be. But checking all this is very simple. Disconnect the Internet from the router (only if you don't have ADSL), and connect it directly to your computer. If the computer sees the network cable, then the problem is either in the router or in the cable with which you connect the PC to the router. You can also look at the article: . 4 The network cable is faulty. And this can happen. But, if we have a cable that we connect the computer to the router, then it is easy to check by connecting it to another device, or by connecting the cable from the provider directly to the computer’s network card.

The network cable is connected to a computer with an operating system installed on it Windows system 10, but no internet? This is a common problem. No matter how many times you connect the cable, the PC does not respond to it and does not change the connection status. And it doesn’t matter whether you use a cable from an Internet service provider or a router to connect. The error will be the same: “The network cable is not connected.”


If you think that the router is giving an error, reboot it; if it is the network cable, change it. But, based on our own experience, we assure you: no matter how many times you change the cable or reboot the router along with the laptop, the problem will not be solved. Try an experiment by connecting this “non-working” network cable to another device and see for yourself. Is the internet connected? This means that the problem is not in the cable, but in the computer, or rather in the operating system installed on it. Let's try to understand why the laptop does not see the network cable.

The very first thing you should do is open the device manager and make sure that everything is in order with the driver for the adapter. It may not be installed or its version may be outdated. In our case, there is a driver: it was loaded into automatic mode when updating the system.


There is also an Ethernet network card, but for some reason it does not see the cable, although it is connected to it.


The adapter is connected, but the cable is not visible (you can see it in the picture).

Solution

First of all, let's reinstall the Ethernet adapter driver. Updating using the system will do nothing, and Device Manager will tell you that the driver for the device is working fine. Enter your PC model in search bar Google and find the manufacturer's website. Specify the model and download the driver for the adapter to your laptop. Run the installation of the file and wait until the process completes. Check your connection! In our case self-updating driver helped.

If there is no driver for your adapter on Windows 10, install the driver for one of the previous versions OS.

As you can see, it's all about the drivers. operating system installs them yourself, but for some reason they fail, and the Ethernet adapter does not see the cable.

Let's look at the situation: your laptop does not see the Internet cable (Ethernet cable), i.e. no network connection. What should you do in such a situation, how to diagnose the problem and resolve the connection issue.

Wireless Wi-Fi network widespread, which opens up huge opportunities for wireless Internet access. But connecting to the network via Ethernet cable remains the fastest and most reliable. Modern laptops, where the network card is installed, are almost always equipped the necessary drivers. All that remains is to connect the cable to a specific port and make a simple connection setup. It happens that the laptop does not recognize the connected wire. There are several reasons for this.

Mechanical problems

The problem can be solved simply. Just unplug the cord and then plug it back in. Sometimes the plug is not fully connected. It must be inserted into the connector until it clicks.

The network card LED blinks when there is a connection green. If this is not observed, contact your provider to check if there is a signal. The most reliable option is to check the functionality of the cable on another computer. If everything works, then the problem is in the laptop.

Should be inspected twisted pair. One of the wires may have broken. Then the cable must be replaced. Dealing with this on your own is difficult. During installation, the cable is often thrown through the wall and only then the twisted pair is crimped. Turn to professionals for help.

Things are much worse if the connector on the network card is damaged. In this case, you cannot do without the participation of service center specialists. They will replace the connector and everything will work as before.

Drivers

Before resoldering the connector, the service center technicians will conduct a full analysis to determine the cause of the problem. It is assumed that the mechanical part is working properly, and the cause of the trouble is the driver. To do this, programmers carry out the following manipulations.

  1. With help command line or Windows Explorer a list of available devices is displayed.
  2. In the list find the column “ Network adapters", where installed network cards are observed.
  3. The boards are removed from the system.
  4. The computer restarts, after which the system automatically finds network devices, installing the necessary drivers yourself.

For older laptops, you will have to install drivers manually. Typically, programs come on disk with your computer. But if this is not the case, then specialists will select and install the drivers necessary to restore access to the network.

Replacing the network card

The network card is one of the most weak points laptop. A small voltage drop will lead to failure of this element. That's why it's worth using surge protectors, which smooth out power surges and prevent the device or the laptop itself from burning out. If the network card is faulty, replacement is carried out only in service center. It is highly not recommended to do this on your own.
