Just yesterday everything was fine, you were enjoying high-speed Internet, but this morning you turn it on, but the computer does not see the network card. However, here you will think about it. The first thing that comes to mind is that it is out of order, you need to urgently run to the tech market for a new spare part.
That’s why it’s a good idea to always buy two completely identical system units at once. So that in case of problems, you can look for a fault by replacing suspicious modules with known good ones.
This is the path for advanced users and computer geeks. A mere mortal user most often cannot afford such excesses. In this case, one should remember the folk wisdom: “The strong and brave walk quickly and easily, but the weak and timid walk long and hard.”
Decoding - if there is nothing to check the equipment with, you will have to check all problem areas sequentially and methodically.
The computer does not see the network card - the main reasons
- The board itself is faulty.
- Operating system malfunctions.
- Network drivers are corrupted.
- Network connection settings have been changed.
- Antivirus or Windows Firewall interference.
In fact, Chinese electronics do not spoil as often as Chinese shoes. Therefore, if you did not drop the system unit on the floor, did not climb inside and did not switch anything, the probability of failure of the network card itself is extremely small. Most likely the settings have changed.

But the Windows operating system is not only smart and quick-witted, but also a rather fragile organization. A sudden power outage can easily cause serious damage to system files and connection settings.
Recovery options
- Restore Windows to an earlier restore point. It is quite possible that after carrying out such an operation and rebooting the computer, everything will work for you. And not only will the network card appear, but also something else good will restore its functionality. Sometimes restoration needs to be done several times. All the same, it’s better and safer than starting to rearrange blocks and buses in the system unit. Moreover, you don’t need to buy anything yet.
- A more radical remedy is a complete reshuffle of the Windows operating system. This path may turn out to be the most rational, provided that your system has been installed for quite some time and recently you have begun to notice a general deterioration in the performance of your computer. Regular cleanings do not provide tangible improvements? It's time to update Windows. New RAM, Seven and Eight are reinstalled within half an hour, so no problem.
Why is it useful to reinstall Windows? Because the distribution includes all the drivers necessary for operation. When installing the system in automatic mode, all the necessary settings are made for all devices, and the user does not need to do anything other than press the Enter button from time to time. Updating drivers separately is not an easy task. More suitable for advanced users.
In addition, to reinstall drivers you will need an Internet connection, which you don’t have. If there are backup Internet connections, you are sure that you are able to find exactly the driver for the network card that you need - then try this path.
You can download a whole package of drivers from the manufacturer’s official website and then let the computer itself determine the most suitable option automatically, using the Driver Installation Wizard.
If the problem really was with the driver, after the update the computer should work normally.
The network card was not found by the computer and is not installed as a device
When you connect some new element to your computer, the operating system detects the connection and then tries to configure it as expected. Sometimes automatic connection does not occur and then you need to perform manual installation and configuration.
Go to the Control Panel and select the menu item Install New Hardware. The New Hardware Connection Wizard interface will open. There are two options to choose from:
- The device is already connected to the computer.
- The device is not yet connected.
Try the “connected” option and look for your lost device in the list that opens. If it is not in the list, it means that the computer has not yet detected it. Then click “not connected yet” and reboot the system. You can do this - turn off the computer, then open the system unit, disconnect and reconnect the network card, perhaps the contact has deteriorated.
After starting the system, repeat the procedures with the Found New Hardware Wizard. If the device appears in the list of connected ones, continue setting up all points in the Wizard.
Incompatible driver update
Sometimes the reason for the card not working can be a failed Windows update. Or, during the process of downloading an automatic update, there were interruptions in the Internet connection, some of the files were downloaded incorrectly. Then you need to reinstall the old driver.
If you have a Windows OS distribution, it is best to take the file directly from the disk. Did everything work before? Or search for the previous version of the driver on the Internet.
Viral infection
Sometimes the reason a network card disappears from sight is a viral infection. Scan your computer with an antivirus. Try to disinfect the system using the Dr. utility. Web CureIt. If it's a virus thing, everything will work out.
When the operating system is reinstalled, the user may encounter the problem of missing network driver. Without this driver, it is impossible to start either a wireless or wired network. If you have the disk, there are no problems, just install the program. And if it is missing, you need to find, for example, a mobile phone/tablet with a connected network in order to download the driver. To avoid such problems, when reinstalling the operating system, you must follow the correct algorithm of actions.
The driver is the link between the operating system and the internal components of the computer, that is, this program connects the OS with the motherboard, video and network cards, and office equipment. These programs are developed by the same companies that produce PC equipment and electronic office equipment, which is what the personal computer interacts with. When buying a computer, the user does not think about various drivers, since they are already preinstalled in the system. But, for example, after the first reinstallation of the OS or the purchase of a new computer, the user will be faced with their absence.
If there is no driver for the network on the computer, there is no way to go online and download from official sites, which will automatically scan the operating system and install all missing drivers. When might you encounter a problem installing a network device driver? In these three cases:
- Even a new computer, just from a store, may lack an operating system, and as a result, a driver.
- When the operating system is installed/reinstalled.
- When a system crash occurs and the driver stops working.
Since recently users are increasingly assembling computers themselves (choosing internal components), a DVD drive may be missing, and as a result, it is not possible to install any driver from the disk.
In this regard, it is advisable to keep the full set of drivers in a separate folder on your PC or download them to a flash card. In this case, you don’t have to look for a mobile device to go to the official pages of the manufacturers’ websites and from there download a program that will automatically install the missing drivers.
Installing the network driver
Before installing the driver, you must identify your computer. All brands and models of computer internal equipment are encoded with special “ciphers”. This is done so that during installation the driver can identify the computer model and its manufacturer. The network device driver code looks like this: PCI/TECH_xxxx&DEV_xxxx&SUBSYS_xxxxxx. TECH means that the computer hardware was manufactured by A4Tech, and DEV is the device ID.Step 1. Equipment identification
In order to find out the code, click Start and enter device manager in the search field. Next, a menu will open with which you can identify the equipment. Press " Network adapters» and select the name of the controller.
Once you do this, the Details section will open. Find their "Properties" and select "Model ID". The first line contains complete information about the device model.
Step 2. Install/update the network adapter driver
This will be the identifier of your equipment. Now you need to find it on the Internet by entering the name in any search engine, for example.The search engine will return the official driver page, and you need to download it to your PC. And then follows the installation procedure itself. If you need to update a network device driver, you do exactly the same thing: find the ID, enter it into the search, download and install.
To install a missing or recent version of the driver, use Device Manager. Perform the same actions in the last step " Update drivers».
Go to the folder where you saved the necessary drivers downloaded from the manufacturer’s official website, and install them using the “Next” button.
Many users, before installing new driver versions, remove old ones to avoid conflicts and inoperability, because even if you did everything correctly, the Internet may not appear on the computer. In this case, you still need to take the advice of users and remove old versions.
How to do it! In Device Manager, you can uninstall the old version of the network driver. Agree with the choice, and the system will remove the network device driver that was previously installed on your computer.
There are two steps left and your computer will work fully. Step one is to reboot and open Device Manager. In place of the removed driver, “ Network controller" In chapter " Other devices».
At the final stage, follow the steps from (updating/installing network device drivers).

One of the problems that a user may encounter after reinstalling Windows is the lack of a driver for the network adapter (network driver) for a wired or wireless network.
And if you don’t have a driver disk at hand, you will have to look for the driver and download it using another device that has Internet access.
In this article we will look at an algorithm that will allow you to avoid troubles that may arise after installing the OS.
What is a driver? This is a program with which the computer operating system interacts with the device hardware (motherboard, video card, network card, printer, scanner, MFP, etc.).
Drivers are developed by companies that produce computer components and peripherals that interact with PCs (for example, office equipment).
Often, modern operating systems (including Windows 7) already have a certain set of drivers that allow you to work with the main components of your computer; we will consider the case when such programs are missing.
The peculiarity of the situation when the network driver is not installed is that it is not possible to use programs to automatically install drivers, since they all use an Internet connection for their work, and since the network driver is not installed, there is no access to the Internet.
The user usually encounters installing network adapter drivers in the following cases:
1. After purchasing a new computer and not having an OS installed on it.
2. After installing the operating system.
3. After a network adapter driver failure.
To solve the problems that arise in the first case, you need to look for the disks that come with your computer. The driver disk for the motherboard contains what we need.
Over the past few years, a trend has clearly emerged that involves the abandonment of the use of optical disc drives not only among manufacturers of laptops, but also desktop PCs.
Users who independently choose the components from which their computer will be assembled also refuse to install a DVD drive.
Advice! We recommend downloading all the necessary drivers (not just the network one) to a separate directory on your hard drive and/or flash drive. This will avoid situations where, after installing the operating system, you will need to look for a drive or PC (tablet, phone) to download drivers from disk or the Internet.
Installing the network driver
The driver installation procedure can be divided into 2 stages: hardware identification and driver installation.
In order to identify manufacturers and specific models of equipment, a coding system for models and brands of computer components was developed.
Typically, the code for a network adapter has the following form: PCI/VEN_xxxx&DEV_xxxx&SUBSYS_xxxxxx, where VEN_xxxx is the equipment manufacturer identifier (Vendor ID), DEV_xxxx is the equipment model code (Device ID).
Step 1. Equipment identification
In order to find out the code, click Start, enter “Device Manager” in the search field and go to the corresponding menu.
Next, you need to find the “Network adapters” or “Other devices” submenu and right-click on one of the submenu items, for example, in our case it will be “Realtek PCIe GBE Family Controller”.
Step 2. Install/update the network adapter driver
After we have found out the equipment identifier, we should copy its name (right-click - copy) and enter it in the browser search field. After downloading the necessary program, you can begin installing it.
Similar actions will occur if you update the network driver.
To install/update the network adapter driver, you need to go to “Device Manager” as described earlier. Select the required item and in the context menu, which is accessible by right-clicking, select “Update drivers...”.
Select “Search for drivers on this computer.”
We go to the directory into which we recently downloaded everything we need, using the “Browse” button, click “Next” and wait for the driver installation process to complete.
There is also an opinion that if you update (reinstall) a network driver, you must first remove the old one, after which you should install a new one.
Important! To remove an already installed driver, you need to go to “Device Manager”, select the network adapter, right-click and select “Delete” in the context menu. After this, the system will warn you that the device driver will be removed, we agree by clicking “OK”.
Have you connected the Internet, but at one point you realized that there is no connection because the network card does not see the cable? This happens quite often, and there are several reasons why an important part of the computer, without which access to the network is impossible, no longer sees the wire from the provider.
If the computer does not see the cable, then the reason lies in the software settings
Let's look at why this happens and how to fix problems with your Internet access equipment.
The most common and simple reason that the adapter in the computer no longer sees the cable is external damage. Check the connector into which the cord is inserted - if it is loose, the wire does not fit tightly, this means that the port is damaged. In this case, you need to replace it or purchase a new network adapter - it is not that expensive, this purchase will not cost you a lot of money.
If everything is fine with the port, check the Internet cable - any damage to the contact can make it inoperative. If it is intact at the contacts, you will have to inspect it along its entire length - at home it is often touched by animals, children or adults if it is poorly hidden. It is worth noting that when installing the cord, you should immediately ensure its safe location - it should lie so that it is not touched by neighbors.
When you find damage, all that remains is to replace the wire and try to ensure that it is laid out more carefully in the future. Note for yourself where it went bad and for what reason. This way you will know how to pull it correctly from the driveway to the computer next time.
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.
Driver problems and network card rollback
If the drivers are damaged or installed incorrectly, the adapter will no longer see the cable. To fix this, do the following:
- Go to Device Manager and select the “Network Adapters” section;
- Click on the name of your network card and in the window that appears, select the Driver tab;
- Click on “Roll Back” so that the system installs the driver that you used previously.
Did not help? In the same menu, try updating the drivers - click on the appropriate button, select automatic search, and the system will find the necessary software for the network equipment. If you don't have drivers on your computer, download and install them yourself. You can find the necessary files by the name of the adapter, which you immediately see when you enter the device manager.
The card is disabled or not working
Sometimes something changes in the system, after which the adapter turns off and therefore does not see the Internet provider's wire. But you can always turn it on again, this is done like this:
- Go to device manager, find the name of the card in the network adapters menu;
- Right-click on the equipment name to open the context menu and select the “Update equipment configuration” function.
If, after all the above steps, the device still does not see the cable or is missing in, there is only one conclusion - this is the problem, so it is worth replacing the adapter. This is not difficult to do; the task can be easily and quickly completed by any specialist or more or less advanced user.
The idea of writing this article was born at the moment when, at the request of a friend, to fix a problem on his computer with a WiFi connection, it was discovered that the network adapter was not in the Windows Device Manager. Let me remind you that this device is responsible for connecting to the Internet via a wireless signal. We began to figure out the essence of the problem step by step, and I will share this algorithm with you today.
Let's think about it and systematize all the possible reasons why the device manager does not see the network adapter.
Lack of WiFi module on the computer
WiFi adapter is broken
This doesn’t happen often, but it does happen, so this option cannot be ruled out. In my practice, there have been cases where both computer network cards that are connected to the PCI slot of the motherboard inside the system unit and much smaller cards installed in laptops have burned out. Since the device is not working, the adapter does not appear in the device manager.
USB connector is faulty
Continuing the topic of breakdowns, we will touch on the option in which the problem is not the adapter at all, but the USB port, which simply does not work. That is, when your computer connects to the Internet through an external adapter connected to this same USB. To check if this is true
- try to insert the adapter into the adjacent port
- if it doesn’t work, or if it’s the only one, which is not uncommon on laptops, then we try to connect another device, for example a mouse, to this connector
In the case when the mouse works, but the adapter does not, this is the reason. If the mouse doesn’t work either, then it’s definitely a USB problem. And it’s even worse if none of the ports is functioning - this alarm bell may indicate either the absence of some drivers for the motherboard, or serious malfunctions associated with the operation of bridges on the motherboard - but this is a topic for another article...
USB extension cable is faulty
In order to better catch a signal that is poorly reaching the computer, “advanced” users use a USB extension cable, which is placed closer to the access point. So, this could be the whole issue - either the cable is leaky or the connector is loose. Try plugging the adapter directly into the computer. Another type of such connection is through a USB hub, when the laptop has a shortage of USB inputs. But there may also be a problem with insufficient power supply to the device. If it is quite enough for flash drives, then it may not be enough for a wifi whistle.
Drivers not installed or lost
Drivers conflict with others or are not suitable for this version of Windows
The case is quite rare, but it happened to me once, as a result of which I was forced to abandon one model of wifi adapter and install another. I couldn’t figure out what was going on - it kept appearing in the dispatcher and then disappeared again. Even repeated removal and installation of factory drivers did not help. Perhaps they simply did not support Windows 10 correctly - I was never able to find out for sure.
Here is my experience in solving the problem when the network adapter is not in the Windows Manager, I hope it will be useful to you in correcting this error.
A network card or network adapter is needed to create a local network, with which you can connect several computers to each other, as well as to connect your computer to the Internet. Sometimes the card starts to work incorrectly, but you can restore it yourself using standard Windows 7 tools.
When to configure the adapter manually
You need to update drivers or change card settings if you have problems connecting to the local network or connecting to the Internet. Please note that such problems are not always caused by the network adapter, but sometimes it is because of it that errors occur that block access to the network.
How to find out the adapter model
The first thing to do is check whether the card is connected to the computer and whether it is recognized by it. The adapter is included with all laptops and computers by default, so if you didn’t assemble your device piece by piece yourself, you shouldn’t think about its absence. But there are times when the wires going to it become disconnected or come off.
A network card (or network adapter) is a device that allows a computer to communicate with other devices. On modern PCs and laptops, the components of this device are integrated into the motherboard.
You will need to open the computer case and check this only if the network card is not displayed in the “Device Manager”:
Card activation
If the network card is connected but not enabled, it must be enabled manually. There are several ways to do this. If the card is not damaged, turning it on will not cause errors.
Via "Device Manager"
The previous section described how to view the card model through the “Device Manager”. Find the adapter you need and right-click on it and select the “Enable” function. If the card is successfully turned on, the down arrow icon will disappear from its icon.
Click on the “Enable” button in the “Device Manager” Using the Control Panel
- Using the Start menu or any other method, launch the Control Panel on your computer.
Open the “Control Panel” - Go to Network and Sharing Center.
Go to the “Network and Sharing Center” - Click on the sub-item “Change adapter settings”.
Click on the sub-item “Change adapter settings” - A list will open, which will most likely contain several cards. One serves as a connection to the wireless network, and the other serves as a connection to the wireless network. There may be additional adapters in the list. Select the one you need and right-click on it and select the “Enable” function. Wait until activation is complete: the red cross icon on the card icon should disappear.
Click on the “Enable” button to activate the adapter
Via BIOS
If the card cannot be activated using the previous two methods, then perhaps this can be done through the BIOS settings.
- Entering the BIOS is done using the Delete key, which must be pressed while turning on the computer. Perhaps the key that activates the BIOS will be different: this will be indicated in the hint that appears in one of the corners of the screen when the logo appears. If you find out the model of your motherboard, you can find on the Internet the button responsible for entering the BIOS.
Enter the BIOS by pressing the Delete key - The design and location of BIOS items and sections may differ depending on its version and motherboard model, but the following algorithm of actions is approximately the same for all versions. Go to the "Advanced" tab.
Open the “Advanced” tab - Go to the “Onboard Devices Configuration” subsection.
Open the subsection “Onboard Devices Configuration” - To enable the card, set the “Onboard Lan” line to “Enabled”. "Disabled" means the card is disabled.
Set the “Enabled” parameter for the “Onboard Lan” line
Video: how to enable a network card in Windows 7
You can disable an extra card using the same methods that allowed you to enable it: through the “Device Manager”, “Control Panel” and BIOS. Only in the last step of the method through the “Device Manager” you need to click the “Disable” or “Delete” button, in the “Control Panel” click the “Disable” button, and in the BIOS change the value from “Enabled” to “Disabled”.
Disable the card through the “Control Panel” Updating and installing drivers
Drivers are necessary to ensure that the card does not conflict with other components and fully performs all its functions. Usually they are installed automatically when you first connect the computer adapter, but sometimes the drivers fail or become outdated. In both cases, you need to reinstall them yourself. This is done through the “Device Manager”.
Automatic update
The positive side of this method is that you will not need to search for drivers manually, the negative side is that you will need an Internet connection, which may not be available if the network card does not work. But if you have the opportunity to connect to the network, you can update the drivers in the following way:
Manual update
The advantage of this method is that you can download the card drivers manually from another computer that has Internet access, and then transfer them to yours and install them. It is recommended to download card drivers strictly from the official website of the company that created it.
What to do if drivers are not installed
If at any stage errors occur that prevent you from installing drivers, you must remove the adapter from Device Manager and restart the computer.
Removing the card from the “Task Manager” After the reboot, open the list of connected devices again, and in it there is the “Other devices” sub-item. It will contain the “Network Controller”, which is your card. Install drivers on it using one of the methods described above.
The network controller is located in the “Other devices” sub-item Video: how to update the network driver
View map options
If you want to find out the physical address, IPv4 parameters, gateway address and other possible information about the adapter, then follow these steps:
Additional method
You can also find out the card parameters through the “Command Line” using the “ipconfig /all” command. “Command Prompt” can be found by going to “Start” - “Accessories” - “Command Prompt”. Running this command brings up information about all physical and virtual adapters recognized by the computer.
Run the command “ipconfig /all” to obtain information How to change card settings
The previous paragraph described how to view information about the network adapter. But you can not only see it, but also change it by following these steps:
Video: how to configure a network card
Updating the network card
The only way to update a network card is to install more recent drivers on it, in which the developers have corrected some previously made errors. New drivers are installed directly on top of the already installed ones. If you cannot install on top, you should remove the device, restart the computer and repeat the procedure. How to do this is described in the section “Updating and installing drivers”.
Can I use two cards?
Two network cards can work simultaneously and relieve each other if one of them is aimed at working with Internet traffic, and the second is aimed at working with a local network. To do this, you need to correctly set the IP, DNS and router parameters for both adapters.
Resetting the adapter
You can reset the adapter settings, namely TCP/IP and DNS, using standard Windows tools or using a third-party program from Microsoft. Conditions under which a reset must be performed:
- Internet connection speed is low or unstable;
- files are downloaded broken, this happens due to the same instability of the Internet;
- When connected, the Internet works fully, but after a few minutes problems begin;
- Manually changing the adapter settings led to other problems with the Internet.
Standard method
Launch “Command Prompt” by going to “Start” - “Accessories” - “Command Prompt”, and enter the commands “netsh int ip reset c:\resetlog.txt”, “netsh int tcp reset” and “netsh winsock reset” which will perform a factory reset. Done, the registry branches and system files will see changes, and you may need to restart the computer.
Execute the commands “netsh int ip reset c:\resetlog.txt”, “netsh int tcp reset” and “netsh winsock reset” in the “Command Line” Through a third party program
You can download the NetShell program from Microsoft, which does not require installation, from their official website. Once you launch it, follow the instructions that appear on the screen to reset all changed settings.
Download the program to automatically reset the card settings Solving adapter related errors
During setup or use of the adapter, the errors described below may occur, which will prevent you from using the Internet or local network. Most of them can be fixed without replacing the card.
The card does not have valid IP settings
You may encounter a similar error when setting IP parameters or scanning a network module using standard Windows tools designed to automatically resolve errors.
Manually obtaining settings
If you have not changed the settings of the adapter, that is, it obtains an IP address automatically, then manually requesting an IP address may fix the problem:
Reset
Resetting settings to default values is the most reliable way. How to do this in several ways is described in the section “Resetting the adapter settings”.
Manual adapter configuration
If the previous methods did not help, you should try setting the settings yourself:
Error "This device cannot start"
This error appears in the “Device Manager” not only with the adapter, but also with other connected devices, and has code 10. To fix it, you need to update the card drivers. How to do this is described in the “Updating and installing drivers” section.
The adapter does not work, does not install, or does not appear
If the adapter does not work, does not install or is not displayed, then the reasons may be the following:
Changed map settings disappear
If, after you close the window with the changed settings or restart the computer, all the changes you made disappear as if you never made them, then there are two ways to solve this problem: set the settings by running commands and change the incorrect values in the registry.
Making changes via the Command Line
