The network adapter on the computer does not work. Is it possible to create two network cards
Question: The laptop does not see network adapter
Laptop DNS-0169860, Windows 8. After reboot I stopped seeing network LAN adapter, and Wi-Fi works fine. Before that reboot, I didn’t install anything, I just watched videos on YouTube. Reinstalling the driver does not help. Neither old nor a new version. In the dispatcher LAN devices The adapter is not shown, and when installing the drivers, they give an error that the device was not found. Can you tell me what's the matter?

UPD: When you turn on the display hidden devices, the adapter is displayed in the manager, however, it says “This device is not currently connected to the computer. (Code 45).”
Answer: Throw off the settings in the bios setup, if it doesn’t help, then apparently there’s a problem with the hardware, it’s there in boot menu It seems that it should also be visible if he is alive.
Question: Can't see the network adapter
Guys, Hello!!!
I do not know what to do! Today after re windows downloads, a red cross appears on the connection network! I thought maybe the cable had come loose, but the cable was fine, I checked it - it works! I go further, go to the device manager, in the network adapter tab, avast! Firewal (I don’t remember what else), I deleted it without understanding what it was, I moved on, rebooted Windows, looked at the BIOS, nothing was revealed, there was still no connection! Then I removed the network adapter from the manager, rebooted the system, updated the devices in the task manager, nothing appeared in the network adapter, this tab simply no longer exists!!! Moreover, at the back of the system unit, the green LED used to blink, as I understand it, this was when it was working, but now everything is completely silent, nothing is on! I tried installing drivers from the motherboard!! Nothing! No sense! I roughly understand that I need to install firewood, but I can’t imagine where to find it????
System 7 64-bit!
Guys, I beg you, help!! My brain is already exploding!!

Question: The network adapter fell asleep and cannot wake up
Introduction (maybe not related to the problem, but you never know)
Let me start with the fact that there were problems in the system with the Visual C++ libraries, which I seemed to have solved, but after that, during the game, a visual artifact crashed onto the entire screen and everything froze, the system did not respond, there were blue stripes across the entire screen. I rebooted, after which the system stopped loading (black screen after loading Windows). I tried to rearrange the video card driver, but it didn’t work. In the end, I decided to reinstall Windows because it was already boiling over, problems began to appear more and more often.
The essence of the problem.
I installed a new one windows system 7 maximum x64. I copied all the necessary data from Windows folders old and successfully erased it. Then I tried to install the network driver in order to gain access to the network and install all the other drivers. The driver was not installed. Instead, he gave me this: "the realtek network controller was not found if deep sleep mode is enabled please plug the cable"
I went online to solve the problem, but nothing I found helped.
What did you do:
- I tried other drivers and driver analysis programs (the latter did not see the network adapter at all)
- installed in BIOS standard settings, turned on and off the realtek network output (and it is in the BIOS)
- unplugged the computer from the network and removed the RAM all night so that the motherboard would turn off completely
maternal asus board m5a99x evo r2.0 realtek
Now I took out the RAM again and left it for the whole day, because they write that different motherboards need different times to turn off

I just don’t understand why this adapter is visible in the BIOS
Because it is flashed in the BIOS. My motherboard has an LPT port in the BIOS, but the motherboard doesn’t have one at all.
Question: Windows 7 does not see the network adapter!
Hello everyone, can anyone help me with this problem:
Today I installed windows 7 (licensed) from a disk, I had windows 10 (it’s just been a month already). The installation went smoothly, but my computer is not connected to the Internet. I went to the "Network and Sharing Center" and shared access" -> "change adapter settings" and it’s empty!! I decided to go to the device manager, but there is no “Network adapters” tab there. I don’t understand what’s wrong. Before that, everything was fine.

Yesterday I reinstalled Windows from 7 to 7, now the Acer laptop does not find the network adapter, but it sees bluetooth, I tried turning it on in the BIOS and turning it off did not work. What should I do if the adapter is dead?
Answer: I saw the network adapter in the device manager after I wiggled the connector a little
Question: The computer does not see the Wireless adapter
The other day I assembled a computer, turned it on and installed Windows 8.1 via BIOS. But there is no Internet, there is a cross, what should I do?
I turned on Lan in the BIOS, there is a network adapter in the task manager, but there is no wireless one. I downloaded all the drivers for the motherboard, video card, network adapter, but nothing helps. I watched the whole video. How can I make my computer see the wireless adapter?
Network adapter: Realtek RTL8168-8111 Family PCI-E Gigabit

Answer: Well, at the docks I didn't find that there was a Wi-Fi adapter on board. The description talks about support for MSI M-Cloud technology, which allows you to do something like your own home cloud- but that's just software solution. To implement it, the docs directly say that you need to have installed module wireless network:
You must have an active network connection and an installed Wi-Fi moudle to
enable Soft AP.
So, alas, you need to purchase a wireless card separately.
PS: And install the rest of the uninstalled devices.
Question: Network adapter drivers fail, freezes and crashes from games
At first I thought it was viruses... I cleaned all the viruses. And again these freezes in games and crashes... and yesterday, after turning on the system unit, the network adapter drivers fell off. I had to do a system rollback... This morning when I turned it on. the same thing... The network adapter drivers have failed.
mat MSI board ZH77A G41. Sometimes the system reboots... in the last few days the PC has rebooted 3 times. And about a week ago... when I turned on the PC, I was immediately thrown into the BIOS. Freezes in games dark screen and departure. I suspect that there is something wrong with the motherboard... What do you think?

Network drivers fall off every time you restart your PC...
Answer: I accidentally went to a phishing site... in the search engine they made the same logo with the official site. Well, without reading the description of the link, I clicked on the picture. The antivirus program was disabled... well, seeing that the site was not the same. He immediately left... well, he didn’t attach any importance to it. A few hours later, when watching a video... I notice that the video card is loading at 100%. Well, I rebooted the PC...downloaded other web pages, etc. he discovered 2 malicious file and deleted them. Afterwards I noticed freezes in games with crashes. And again, percent. It started loading 100% when idle after quitting games... I had to reboot. In GTA5 online, the video card drivers crashed and were restored... Afterwards I tested the video card in a furmark... 68 fps, the temperature did not rise above 80c. Afterwards I was advised to download Malwarebytes Anti-Malware... well, I scanned the system with it and viruses came out again. Well, I deleted them as I was advised on a special website. but every time there were new viruses... Afterwards, Kaspersky scanned the system and it cured... Some files were quarantined... some were deleted. Well, crashes from games have not stopped... and the system has also started rebooting and crashing network drivers. In any games and at any settings, the loading of the video card jumps like a sewing machine. The asus r9 290x dc2 video card never warmed up above 80c. I checked it on another system... everything is fine. And yet... about a week ago or a little more... suddenly, when I turned on the PC, I was immediately thrown into the BIOS... I did not reinstall the system after the viruses.
Question: Drivers for the network adapter do not work
One fine day (today) I noticed that the Internet was not working. There is no option in the parameters of this modem, and it’s completely kaput.
I decided to reinstall the driver on the network adapter, but the problem did not solve. The computer advises installing them from the Support Center, but it does not work without the Internet. This driver is needed for the M5A78L-M motherboard from Asus, called Qualcomm Atheros AR8171/8175 PCI-E Gigabit Ethernet Controller (NDIS 6.20) #2. I install from the disk that was in the box when I purchased it. Before this, I sat at the computer for 3 days after reinstalling Windows normally.
What to do, tell me?
Connection via Ethernet cable, which is connected from a modem (the model of which, unfortunately, I can’t say now) to Wi-Fi TP-Link router TL-WR740N, whose menu I also cannot enter in the browser.
In ipconfige there is nothing at all other than IP protocol settings for Windows.
Answer: try removing the adapter from device manager, along with all drivers, and installing it again

By the way, network server does not mean “network server”, but home server, which should be visible in Explorer, but isn't.
And in the assistant everything is ok
A computer is a complex machine that interacts with a huge amount various 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 they cannot see the cable on their PC. What to do in in this case? What could be the reasons similar phenomenon? What should I do to restore my Internet connection?
Damage
The first and most common cause of the problem is the presence physical damage at 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 reasons 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 one or another is outdated on the computer. software for equipment. 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 title network card and select "Drivers" there.
- Click on "Rollback".
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 to earlier ones.
With reinstalling drivers, everything is simpler - just download or upload using installation disk software 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 what to do in this case? Doesn't matter about the built-in component we're talking about 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 check operating system for the presence of viruses. They are often the cause of most problems and failures.
You can detect a virus using 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.
Probably many people are familiar with the situation when it becomes necessary to connect a computer to the Internet using network cable, or over Wi-Fi, and it turns out that the connection does not work because there is no network adapter in the device manager. And here it doesn’t even matter whether you have a laptop or a regular PC. Windows 10, Windows 7, 8, or even Windows XP are installed on it. As a result, we simply will not be able to connect to the Internet. Very often people encounter this problem after relocating Windows. Below in the article I will try to explain why this happens, what network adapters should be in the device manager and what to do if they are not there.
Let's first figure out what network adapters are. Apart from Bluetooth (we are unlikely to connect to the Internet through it), then there are two left:
- Wireless network adapter – also known as Wi-Fi. It’s easy to guess that it is responsible for connecting to the Internet via Wi-Fi. As a rule, it is built into every laptop and is not included in the original desktop computers. But you can buy it in addition.
- Network card, or Ethernet adapter (LAN) - it is used to connect via a network cable. Available on all PCs ( LAN port on motherboard, or separate card) . LAN is also available on almost all laptops. Except ultrabooks. USB-LAN adapters are used there.
In the screenshot below you can see what these network adapters look like in Device Manager. Please note that depending on the manufacturer of the laptop, PC, or adapters, they may be called differently. There may also be many other adapters, such as WAN Miniport.
To open the device manager, you can use the search in Windows 10, open it through properties in "My Computer", or press the Win+R key combination and execute the command mmc devmgmt.msc.
As practice shows, the adapter (or both) is mostly missing for three reasons:
- The adapter is simply not in your device. As I wrote above, PCs usually do not have a built-in Wi-Fi module. And accordingly, it cannot be displayed in the device manager. But you can always buy such an adapter and install it. You can read the article: . Or the same network card may not be in the laptop.
- The driver for Wi-Fi or Ethernet adapter is not installed. This is the most popular reason. In this case, there should be unknown devices in the device manager (if the adapter is physically present). On the "Other devices" tab. This can also include BIOS settings. In some cases, the WLAN or LAN adapter may be disabled in the BIOS settings.
- The adapter is simply broken. It’s not uncommon for network cards to burn out on desktop computers. And Wi-Fi modules on laptops fail. You can always buy a network card (USB or PCI) and install it in your PC. Wireless module you can also change it. It is possible for both PC and laptop. And here's another article on the topic: .
Let's look at each adapter in more detail.
What to do if there is no Wi-Fi adapter in Device Manager?
Almost always in the title wireless adapter there are such words: Wireless, WLAN, Wireless Network Adapter, 802.11. They look something like this:
As you can see, I have two of them. One is built into the laptop, and the second is connected via USB. The one next to which there is an arrow icon is disabled.
If you do not have such adapters, but you know for sure that your laptop (or PC) has Wi-Fi module, then check the "Other devices" section (in the same device manager).
Basically, network adapters appear there as . And then you need to install the driver on them. Or immediately download the WLAN drivers for your laptop model and start the installation. I have already written more than one article on this topic:
- AND separate instructions for laptops and .
But do not forget that the module may simply fail. It is clear that it will not be identified in the system.
If there is no network card (LAN)
There are much fewer problems with network cards. If only because Windows almost always automatically installs a driver for Ethernet adapters. Unless in Windows XP you have to install the driver manually. But this is no longer very relevant now.
As for the drivers for these adapters, I wrote about them in the article: .
This is what the network card looks like in Device Manager (of course, your name may be different):
If it is not there, but physically it is on your computer, then most likely it is broken. By tradition, we check the “Other devices” tab. If there isn't unknown devices, the card will probably have to be replaced. Or buy a USB Ethernet adapter.
To briefly summarize this article, it goes like this:
- Check to see if you have the required network adapter on your computer.
- Let's make sure that the problem is not in the drivers.
- If all else fails, we take the computer to be repaired, or change the necessary adapter ourselves. It should be noted that at home it is very problematic to determine the reason for the lack of an adapter and find a breakdown.
It turned out to be a complex article, and a little confusing. This is because this problem is very controversial. There are many different things that vary greatly depending on the device, manufacturer, settings, etc.
As always, I look forward to your messages in the comments. Just one request, please write on the topic of the article.
A network adapter (also called a network card) is a device without which it is impossible to establish a connection to worldwide network. In some cases, turning it off and restart helps solve communication problems. Many network cards can be connected to a computer, with different network connections. However to the average user this is often not necessary. This article is intended for Windows owners 7, but will be useful for almost every Win-line operating system.
To enable the network adapter in Win 7, click the "Start" button, find the "Computer" item on the right, click on it right click mouse calling context menu. In it, select the “Properties” line by clicking on it once. In the “System” control panel window that appears, find the “Device Manager” tab on the left and go to it. A list similar to the screenshot below will open. We look for the “Network adapters” item in it, click once, getting a drop-down list. If there are no sub-items in the list, or you cannot find an item called “Network Adapters” at all, the network card may not be physically enabled or is faulty. What to do in this case? Below we will give some tips and solutions (see point 6). Let's continue with the setup. The screenshot attached above illustrates what enabled and working network adapters look like. If one of them shows an arrow (the icon is circled in red), the card just needs to be turned on. To do this, right-click on the image and select “Engage” from the context menu. The arrow should disappear and the network adapter should work.
There can be many reasons for a lack of network connection; they are not limited to a faulty network card. If after reading this guide you still have questions, ask them in the comments or contact technical support your Internet provider.
