The network card does not see the cable: ways to solve the problem
A computer is a complex machine that interacts with a huge number of different components. Sometimes some devices malfunction. For example, when working with the Internet, various problems arise. Quite often, people are faced with a situation in which the network card does not see the cable on the PC. What to do in this case? What could be the reasons for this phenomenon? What should I do to restore my Internet connection?
Damage
The first and most common cause of a problem is physical damage to the connected equipment. The network card does not see the Internet cable? It is necessary to first check its integrity. It is likely that the cord is crushed or completely broken.
Next, it is recommended to verify the integrity of the cable connection sockets, as well as the plugs. If everything is normal, you can look for the cause of the problem elsewhere. The presence of damage means that the network card will not be able to see the cable until the problem is fixed.
What helps here, as a rule, is replacing the cable and connection plugs. No other options are provided.
Settings
The next option is also not so rare. Often the network card does not see the cable from the Internet if the network settings are messed up. This phenomenon usually does not cause panic among users.
To eliminate this situation, the user is asked to open the “Network Control Center”. In the window that appears, look at the results. If there is a red cross between the computer and the connection, there really is a problem with the Internet. Most likely, the network card does not see the cable due to incorrect settings.
Correcting the situation boils down to the user clicking on the red cross between the PC and the Internet, and then waiting for the test results. Once it is completed, you can follow the help wizard to set up your network.
If the network card no longer sees the cable, you need to contact your provider. Data is taken from him to configure the network, which is entered into the appropriate fields (for example, IP address). It is proposed to work in the same “Network Control Center”.
Drivers
But that's not all! A computer is a complex device. When problems occur, it can be difficult to determine the source of the problem. Therefore, solving the problem consists of searching through all possible causes of failures. There are not so few of them.
The network card does not see the cable? It is possible that the problem lies in the software. More precisely, in the drivers. It is likely that some hardware software on your computer is outdated. And therefore it is not recognized in the operating system.
The situation can be easily corrected. To do this you need:
- Open "Device Manager". The best way to do this is by right-clicking on the My Computer shortcut. Next, you need to select “Properties”, and then select the desired service.
- Open the “Network adapters” section.
- Click on the name of the network card and select “Drivers” there.
- Click on “Roll Back”.
This technique helps when the network card suddenly starts to malfunction. That is, when the cable was previously recognized. This technique allows you to roll back the network card settings to earlier ones.
With reinstalling drivers, everything is simpler - just download or download the software using an installation disk on the official website of the network card manufacturer, and then install it. Just a few minutes and it's done!
Shutdown
Users often complain that their built-in network card does not see the network cable. What to do in this case? It doesn’t matter whether we are talking about a built-in component or not. The main thing is that the reasons for the failures remain the same.
It should not be ruled out that the network card is disabled or does not work at all. You can check this in Device Manager. If in the section with network adapters there is a red cross next to the name of the network card, then the problem really is with a non-working device.
As a rule, it is recommended to simply replace the non-functioning component. And then the Internet cable will again be recognized by the operating system. In practice, people still do not often encounter equipment incompatibility. But it still shouldn’t be ruled out.
Incompatibility
More and more often, users are faced with a situation where the network card does not see the cable. Windows 7 allows you to detect problems very quickly. All listed layouts are relevant for this OS.
But owners of Windows 10 may encounter a problem such as hardware incompatibility. Some modems, speakers, microphones, mice and other computer components do not work with this operating system. Therefore, you can get rid of the problem:
- reinstalling the operating system;
- by purchasing a new network card/modem.
No more options are offered to combat equipment incompatibility. Every user should remember this.
Viruses
If all of the above options did not help, and the network card does not see the cable, you can scan the operating system for viruses. They are often the cause of most problems and failures.
You can detect a virus using an antivirus program. After scanning your PC, you need to disinfect the operating system. Next is to restart the computer. If the network card did not see the cable due to the presence of viruses, then the described steps will help resolve the problem.

Settings failed
The network card does not see the cable in many situations due to incorrect Internet access settings. To check this, go to your computer settings, Network and Sharing Center section. If there is a red cross on the connection diagram between the PC and the Internet icon, click on it, after which the system will diagnose the network.
Using the hints, you will understand what the problems were. If the system does not eliminate them on its own, you will receive information about what needs to be done to do this. If the network settings are lost in the parameters and they are not entered automatically, enter all the necessary data. They can be obtained by contacting your provider or reviewing the contract that you signed when connecting to the Internet.
The network card does not see the cable: instructions for solving the problem
A wired internet connection is preferable due to higher data transfer speeds and overall signal quality. However, the presence of a large number of physical components located over a fairly large space creates risks of damage to 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 high-definition video, but today your network card does not 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 recent years, installers from ISP service departments have shown obvious negligence in performing 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 of 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 of increased danger is created. 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.
- Carefully trace the network cable in all visible areas of the installation. If damage is detected, it is best to immediately replace the entire unusable piece.
- 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.
- 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. Do not rush to open the system unit immediately. The most common reason is broken Windows settings.
Go to Control Panel\All Control Panel Items\Network and Sharing Center and change the settings
If the Internet worked fine before, you can assume that rolling back the operating system to one of its 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 that your network connection settings are correct. 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? A complete set of necessary drivers is located on the Windows operating system distribution disk.
Sometimes it makes sense not to bother searching for specific programs, but to reinstall the entire Windows operating system at once. 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 using this method is the almost inevitable loss of all user settings on the computer and the need to spend time re-installing all working applications. Usually, they resort to reinstalling Windows in cases where the system itself begins to not work very well, slows down, glitches, and often crashes.
Try updating, connecting, rolling back, removing network card drivers
You can try a less drastic solution - run automatic system updates. However, if you do not have the latest version of Windows, technical support may already be repainted and no update is available. The situation is approximately the same with left-wing versions of Windows. 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.

The proxy server is incorrectly configured
It is simply impossible to set such settings by accident, but often computers do not connect to the Internet precisely for this reason. For a regular home Internet connection, no proxy servers are needed. They are usually used in factories and offices.
I’ll show you using the Mozilla Firefox browser as an example. You can look for similar settings in Opera, Yandex Browser, Google Chrome, etc.
In general, you need to go to the browser, find and open its Settings
.
Next we need to find Connection Settings
and check the box next to
Automatically detect proxy settings for this network
(the names of the items may differ for you, but the essence remains the same).
That's all. I hope my article was useful to you and helped you understand why the Internet via cable does not work on your computer. If you haven’t found a solution to your problem, write in the comments, we’ll figure it out together.
What should I do if the network cable is not connected even though it is connected?
The Internet and network technologies have long been an integral part of our lives. And if the Internet stops working, then for most this is a serious problem. This article will consider a situation in which the Internet and local network do not work, and in the lower right corner of the monitor near the clock a red cross icon is displayed with the inscription “Network cable is not connected,” although the cable is inserted into the computer’s network card.
Possible causes of the error “Network cable is not connected” when the cable is connected
This situation is possible for several reasons. Moreover, it can arise completely suddenly. A computer or laptop may not see the network cable because:
- There are problems on the side of your provider if the network cable comes into your computer directly without modems and routers;
- The network cable is damaged around the perimeter or there is poor contact at the end of the chip that is inserted into the computer’s network card;
- There is a problem with the network card drivers;
- The network card is not configured correctly;
- There are problems with the modem or router to which the network cable from the computer is connected.
How to fix the problem when the network cable is not connected even though it is connected?
So, the first thing to start solving this problem is to reboot the modem or Wi-Fi router, after first changing the cable port into which the wire from the computer is inserted to any other of the four available.
Changing ports on a modem or router
If the cable goes directly without modems and routers, then you need to call the support of your Internet provider and find out if they have any work on the line. which could cause the problem of an unconnected network cable.
If this does not solve the problem and the computer still does not see the network cable, then you should remove the cable from the network card connector and move it at the junction with the transparent chip - the tip.
Network card connector in computer
After this, try inserting the cable back into the computer and moving the end again, but without pulling it out of the computer.
While doing this, look at the computer monitor. If a connection appears when you move the cable, then your cable crimp is broken and you need to re-crimp it with a transparent RJ-45 chip.
Crimping RJ-45 internet cable
If the above actions did not lead to any result, and the computer stopped seeing the network cable for no reason (before the problem occurred, windows were not reinstalled, the motherboard or Wi-Fi router was replaced), then you need to localize the problem. To do this, you need 1 more computer or laptop with a working network connector.
Try inserting a cable into it and see if another computer can already see it. If the situation has not changed and the other laptop still writes that the network cable is not connected, although it is connected, then there is a problem with the cable. It's damaged somewhere.
If another computer sees the cable, then there is a problem with your computer’s network card or its settings.
You need to try reinstalling its driver, and also check that the settings in the Spped&Duplex section are set to “Auto“.
To check this, right-click on the red cross with the inscription about the unconnected cable and select “Network and Sharing Center”
Sign in to the Network and Sharing Center
Next, select “Change adapter settings” at the top left and find “Local Area Connection“.
Going to computer network cards
Selecting a wired network card
Now double-click on it with the left mouse button and select the “Configure” button, then the “Advanced” tab.
Entering the network card settings
Here we look for Spped&Duplex (Speed and duplex) and check its value on the right. It should be "Auto".
Checking the network card settings
If all of the above did not help you, then you will have to change the network card to a new one.

You need to set up an Internet connection
Not all providers use automatic distribution of IP addresses and DNS servers. Those. It’s not always possible to just insert a cable and everything will work right away. Very often you need to set up a connection with your provider (PPPOE, PPTP, L2TP) by specifying your login and password to connect. It is better to find out exactly what protocol you are using and how exactly to configure it from your provider.
Some companies require you to manually register the IP address allocated to you and the necessary DNS servers (usually they are specified in the agreement with the provider). To do this, open Control Panel
➜
(Network and Internet)
➜
Network and Sharing Center
➜
(Change adapter settings)
.
Now right-click on your network connection and select Properties
.
Find Internet Protocol Version 4
and click
Properties
.
Manually enter the required addresses and click OK
.
It also happens the other way around, when “manual” settings are installed, but “automatic” ones are needed.
The network cable is not connected. What to do?
Despite the popularization of wireless Internet, most of us still use a wired connection at home. Wired Internet is good because it is stable, you can use an unlimited tariff, and the cost of the tariff plan is quite low. True, when connecting, installers pull a network cable into the apartment. This is something I would like to talk about in more detail.
Surely many of you have encountered a situation where, instead of connecting, you saw the message “Network cable not connected.” What is this problem and how to solve it? Let's consider the most frequently occurring situations.
Power outage or equipment problems
Let’s say you are surfing the Internet and then the same error “Network cable is not connected” appears. This can happen if there are some problems with the signal transmission equipment. Most likely, in a few minutes everything will return to normal and you will forget about this error for a long time. Therefore, I strongly recommend waiting at least 10-15 minutes before calling your provider.
As for power outages, such cases are by no means uncommon, and the power is turned off in the very wing where the equipment is located. Accordingly, it stops working. In such cases, you are powerless to do anything and the only option is to wait for the repairmen to turn on the electricity.
Connect the network cable
If you turn on the computer and see the above error, then it is quite possible that the cable is really not connected. This could happen, for example, because one of your household members, for one reason or another, removed it from the nest. But pets were unlikely to be able to do this, since the cable is rigidly fixed in the socket with a lock and it is unlikely that the same cat will be able to simply disconnect it. However, pets are not capable of this.
You can insert the cable from the back of the system unit. In a laptop, the socket is usually located on the side of the device.
The network cable is damaged
If you look at the network cable, you can see for yourself that accidentally damaging it is not as easy as some users think. This, however, does not exclude the fact that the cable is still damaged. It can be damaged by the same pets, who for some reason love to chew wires and cables. It can also be damaged during any housework.
If the damage occurred at your home, you just need to twist it at the site of the cable break; this will take no more than 5-10 minutes of your time. If the damage occurred outside your apartment, it is better to leave the solution to the problem to the provider, whom you should call and describe the problem.
Lost contact with connector
The connection between the network cable and the connector is not always of good quality. In addition, if you constantly access the connector, the contact at the connection point may be broken, which in turn leads to problems with the connection, including the “Network cable is not connected” error.
What needs to be done? You just need to re-crimp the cable. It’s not difficult to do this yourself, but if you still don’t have the skills, it’s better to turn to the same provider for help.
Network card is faulty
Everything is simple here: the network card has given up its life. What to do? Buy another, fortunately, this is one of the most inexpensive components of a modern PC. To check, connect the cable to another computer or laptop: if there is no error on it, then the network card could really be faulty.
By the way, if you have several network cards, it is quite possible that the one to which you connected the cable is simply disabled at the moment. You can enable it through your connection settings.
The router is faulty
If you use a router to connect to the network, then perhaps the problem is there - the device could have failed. It's easy to check: connect the network cable directly to the network card. If the error disappears, it means something happened to the router. Also try disconnecting the device from the network and connecting it again, perhaps this is just a glitch.

The indicator blinks, but still does not work
If the indicator on the motherboard is blinking, most likely there is a signal, but for some reason the icon on the “Taskbar” is still crossed out. In this case, you need to install the network driver or reinstall if there are any problems with it. This situation can happen if, for example, you have just reinstalled the system. Until you install the necessary network driver, the Internet on your computer via cable will not work. To search and update drivers, I recommend using the program described in.
After installing the network drivers, there should be no icons (yellow exclamation marks, etc.) in the device manager next to the network adapters.
Troubleshooting no connection issues using a Wi-Fi router
What are the differences between 3G and 4G networks: features, advantages and disadvantages
Often the reason that access is disabled is because the router is overloaded or crashes. If there is a constant drop in speed, loss of connection or freezes, or poor connection, you should reboot the modem. To do this, there is a Reset button on the case, which you need to hold for 10-15 seconds.
Sometimes you have to roll back to the factory state if there is no Internet on Windows 10. But in this case, all the specified settings will be lost and will have to be restored. A soft reset on each router is performed in a similar way, only the location of the partition differs. In the web interface you need to find the “Factory settings” item and click “Apply”.
If the WAN port of the router is burned out
It’s not uncommon for the WAN port itself to burn out. Well, it’s clear that the router will no longer see any cable. As a rule, this happens after a thunderstorm or power problems. Although not necessarily, there may be other reasons. But in a severe thunderstorm, it is better to disconnect the network cable from the WAN port of the router. Just in case.
What to do in such a situation? You can take the router for repairs, or buy a new one. But there is another option. If the WAN port really burned out, and the Wi-Fi network and the router itself are working normally, and you can go into its settings, then you can try to flash the router with alternative firmware, which has the ability to assign one of the LAN ports as a WAN port. I will try to write in more detail about this method in a separate article. In the meantime, you can search for such firmware for your router on the Internet. Ask something like this: “alternative firmware for TP-LINK TL-WR841N.” Just substitute your router model there.
It’s not a fact that everything will work out, but you can try. Moreover, considering the fact that otherwise you will most likely have to buy a new router.
conclusions
If you find out that the problem is not with the cable or the provider, but with the router itself (and the WAN indicator does not light up), then most likely this is a technical failure. As we already found out above, the WAN port usually burns out. Next, we either repair/replace the router, or try to flash it with alternative firmware and use the LAN port instead of the WAN. You can also check the router with friends, for example. By connecting it to their internet.
Fixing the problem with no Internet on a phone running Windows 10
Why does the Internet speed drop after installing or updating Windows?
Some mobile phones use the Windows 10 operating system. For example, the Lumia smartphone runs on this OS. The wireless network may also fail on the phone due to incorrect installation or installation of an unofficial version. The best solution would be to reset to factory settings. Then the user will have to independently install Win 10 on the smartphone by downloading it from the Microsoft website.
When auto-updating, you should check that the WiFi settings are correct. You also need to make sure that you are using the correct Microsoft account.
The network may stop working due to program incompatibility. It is recommended to remove mobile optimizers and cleaners. Disable or reinstall antivirus.
Changing the proxy port settings also helps. You need to register a port in your smartphone via points 88 and 77, and set the PC address as IP.
In Internet explorer, in the search bar of the browser, you need to enter the IP address and port, then download and install the certificate. In Windows Insider, install updates, return to Wi-Fi settings and disable proxies.
Then, in the same application, in the GetPreview Bild section, you need to use InsiderFast. A reboot will begin, after which the problem will be fixed
