Windows 7 network adapter is not detected. The network adapter does not have valid IP settings

Good day.

When installing a new Windows, as a rule, the system automatically configures many settings (will put universal drivers, will set the optimal firewall configuration, etc.).

But it just so happens that some things are not automatically configured when reinstalling Windows. And many who reinstalled the OS for the first time are faced with one unpleasant thing - the Internet not working.

In this article I want to look at the main reasons why this happens and what to do about it. (especially since there are always a lot of questions regarding this topic)...

The most common reason why there is no Internet (note after installing a new Windows OS)- this is the absence of a network card driver in the system. Those. the reason is that network card it just doesn't work...

In this case, a vicious circle results: There is no internet, because... there is no driver, and the driver cannot be downloaded - because... no internet! If you don’t have a phone with Internet access (or another PC), then most likely you can’t do without the help of a good neighbor (friend)...

Usually, if the problem is related to the driver, then you will see something like the following: a red cross will light up above the network icon, and an inscription something similar to this: "Not Connected: No connections available"...

In the control center - on the right there will be a tab "Changing adapter settings" - this is what you need to open.

In network connections you will see your adapters with drivers installed. As you can see in the screenshot below, my laptop does not have a driver for the Wi-Fi adapter (there is only an Ethernet adapter, and even that is disabled).

By the way, check, it’s possible that you have the driver installed, but the adapter itself is simply turned off (as in the screenshot below - it will just be gray and it will say “Disabled”). In this case, simply enable it by right-clicking on it and selecting the appropriate menu in the context menu that pops up.

Network connections

I also recommend looking into the device manager: there you can see in detail which equipment has drivers and which do not. Also, if there is a problem with the driver (for example, it does not work correctly), then the device manager marks such equipment with yellow exclamation marks...

To open it, do the following:

• Windows 7 - in the Run line (in the START menu), paste devmgmt.msc and press ENTER.
• Windows 8, 10 - press the WIN+R button combination, paste devmgmt.msc and press ENTER (screenshot below).

In Device Manager, open the Network Adapters tab. If your equipment is not in the list, it means there are no drivers in the Windows system, which means that the equipment will not work...

How to solve the driver issue?

1. Option #1 - try updating the hardware configuration (in device manager: just right-click on the network adapters header and select the desired option. Screenshot below).
2. Option No. 2 - if the previous option did not help, you can use special utility 3DP Net (It weighs about 30-50 MB, which means it can be downloaded even using your phone. Moreover, it works without an Internet connection);
3. Option number 3 - download on the computer of a comrade, neighbor, friend, etc. special driver package - ISO image by ~10-14 GB, and then run it on your PC. There are a lot of such packages floating around the Internet, I personally recommend Driver Pack Solutions ;
4. Option No. 4 - if none of the previous ones worked and did not give results, I recommend looking for the driver by VID and PID.

And this is what the tab will look like when the driver for the Wi-Fi adapter is found (screen below).

If you can't connect to the network after updating the driver...

In my case, for example, Windows refused to search for available networks and after installing and updating the drivers, it still showed an error and an icon with a red cross.

Next, the troubleshooter will automatically begin to fix problems related to network inaccessibility and advise you on each step. After the button has been pressed "Show list available networks" - the troubleshooting wizard configured the network accordingly and all available Wi-Fi networks became visible.

Actually, the last step remains - select your network (or the network for which you have a password to access) and connect to it. That's what was done...

Entering data to connect to the network... (clickable)

2. Network adapter is disconnected / Network cable is not connected

One more common cause lack of Internet is a disabled network adapter (with the driver installed). To check this, you need to open the network connections tab (where all network adapters that are installed in the PC and for which there are drivers in the OS will be shown).

The easiest way to open network connections is to press the WIN+R buttons together and enter ncpa.cpl (then press ENTER. In Windows 7, the run line is located in START"e).

Opening the Network Connections tab in Windows 10

In the network connections tab that opens - pay attention to the adapters that are displayed in gray (i.e. colorless). Next to them there will also be an inscription: “Disabled”.

Important! If there is nothing at all in the list of adapters (or there is no adapter that you are looking for) - most likely you simply do not have it in your system the required driver(the first part of this article is devoted to this).

To enable such an adapter, simply right-click on it and select “Enable” in the context menu. (screenshot below).

After the adapter is turned on, pay attention to whether there are any red crosses on it. As a rule, the reason will even be indicated next to the cross, for example, in the screenshot below “The network cable is not connected.”

If you have similar error- you need to check the network cable: it may have been chewed by pets, touched by furniture when it was moved, the connector was poorly crimped, etc.

3. Incorrect settings: IP, default gateway, DNS, etc.

Some Internet providers require you to manually set certain settings TCP/IP (this applies to those who do not have a router into which these settings have been entered once, and then you can reinstall Windows at least 100 times).

You can find out whether this is so in the documents that your Internet provider gave you when concluding the contract. Usually, they always indicate all the settings for Internet access (as a last resort, you can call and check with support).

Everything is set up quite simply. In network connections (how to access this tab is described above, in the previous step of the article), select your adapter and go to its properties.

Ethernet Network Adapter Properties

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 adhere to correct algorithm actions.

The driver is 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 electronics. office equipment, what it interacts with personal computer. When buying a computer, the user does not think about various drivers, since they are already pre-installed 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.

1. Even a new computer, just from a store, may lack an operating system, and as a result, a driver.
2. When the operating system is installed/reinstalled.
3. When it happens system failure, and the driver stops working.

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

Step 1. Equipment identification

Step 2. Install/update the network adapter driver

To install a missing or recent version of the driver, use Device Manager. Perform the same actions in the last step " Update drivers».

How to do it! In Device Manager you can remove old version network driver. Agree with the choice, and the system will remove the network device driver that was previously installed on your computer.

Just yesterday everything was fine, you were enjoying high-speed Internet, and this morning you turn it on, but the computer does not see the network card. However, here's where you 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 good idea– 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

1. The board itself is faulty.
2. Irregularities at work operating system.
3. Network drivers are corrupted.
4. Network connection settings have been changed.
5. 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.

Go to Control PanelAll Control Panel Items Network and Sharing Center and change settings

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

1. Do Windows rollback to an early recovery 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, there is no need to buy anything yet.
2. 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 RAMs, 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 V automatically, using the Driver Installation Wizard.

If the problem really was with the driver, after the update the computer’s operation should return to normal.

The network card was not found by the computer and is not installed as a device

When you connect some kind of new element, the operating system detects the connection and then tries to configure it as expected. Sometimes automatic connection does not happen and then you need to produce manual installation and setting.

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:

1. The device is already connected to the computer.
2. The device is not yet connected.

Try the “connected” option and look for your lost device. 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 system unit, disconnect and reconnect the network card, the connection may have 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 may 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 previous version drivers on the Internet.

Viral infection

Sometimes the reason why a network card disappears from view is 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.

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 through which the computer's operating system communicates with the device's hardware ( motherboard, video card, network card, printer, scanner, MFP, etc.).

Drivers are developed by companies that produce computer components and peripherals that interact with the PC (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 abandoning the use of drives optical disks not only among laptop manufacturers, 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.

For the purpose of identifying manufacturers and specific models equipment, a coding system for models and brands of computer components was developed.

As a rule, 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 into the browser search field. Download the necessary program, you can start 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”.

Driver Updater program from Carambis

If you need to search universal programs, which are able to function on different operating systems: we mean utilities for creating group policies, programs for cleaning the system from viruses and, of course, software for working with OS drivers - best solution will be used Carambis programs Driver Updater.

Thanks to Driver Updater, you can not only get the software you need, but also save big. After all, one subscription purchase allows you to connect two computers at once.

Probably many people are familiar with the situation when it becomes necessary to connect a computer to the Internet using a network cable or via 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:

1. 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.
2. Network card, or Ethernet adapter (LAN) - it is used to connect via network cable. Available on all PCs ( LAN port on the motherboard, or a 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:

1. 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.
2. 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.
3. 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, the name of a wireless adapter contains the following 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 the driver for Ethernet adapters. Unless in Windows XP you have to manually install the driver. 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 (Obviously, 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:

1. Check to see if you have the required network adapter on your computer.
2. Let's make sure that the problem is not in the drivers.
3. 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.

The network adapter for the computer/laptop is responsible for access to the Internet, which modern devices connects via USB or BNC connector. Because it's built-in, and the ability to explore World Wide Web in most cases, the technician sets it up; the question of what it is and how to make it work arises if breakdowns occur. It's not easy to figure this out, but it's quite possible.

What is a network adapter

An additional connecting element between a PC or laptop and other devices that provide access to the Internet is called a network adapter (terminology from the manufacturer Intel processors). In the majority modern computers it is built into the motherboard. There are other names for the device. What is a network card, card or Ethernet adapter? These are all variant names for one device.

What function does it perform?

In the model OSI systems The network adapter is responsible for the functioning of the second, data link layer. In conjunction with the driver, it also ensures the operation of physical equipment. Each manufacturer decides for itself the task of distributing responsibilities between them. For link layer In addition, the OS (operating system) module responds. Together they perform two main operations: sending and receiving data from the network to the PC and vice versa, and also take part in:

• monitoring incoming/outgoing traffic;
• remote configuration change;
• improving network performance and prioritization;
• remote activation from central workstation;
• encoding/decoding sent/received data;
• packet formation (transmission/reception mode).

Classification

Although most modern PCs have built-in network cards, they can break down and require replacement. To do this, it is not necessary to completely disassemble the computer, since there are two large groups these devices:

1. External. Some are connected via the PCI connector of the motherboard, others use the ISA bus.
2. Built-in. They are also called integrated. The output is presented as a connector on the panel near the USB ports. Nearby there are indicators - LEDs, which are used to guide you regarding the performance of the device. Plus of the built-in device: convenience. Cons: unreliability.

3Com approached classification from a different angle. In it, all adapters are divided into generations. Varieties include:

1. First generation adapters. Built on discrete logic chips. They had low performance - even if the computer memory was large, the adapter buffer could only hold one frame. There were many types, each of which needed its own driver. In addition, the OS modules were not standardized. As a result, configuring the network card was difficult. The devices were used on old computers.
2. Second generation adapters. ASIC chips are used, the size of the buffer memory allows for multi-frame transmission in parallel mode. The reliability of 2nd generation adapters has been increased, and standard specifications for drivers and interfaces have been developed. In addition, the transfer speed has increased.
3. Third generation. This latest devices, to which 3com refers its EtherLink III boards. Frame processing is conveyor-based. The adapter is configured automatically. It is connected to the network via a BNC connector (for the cable type - twisted pair).
4. Fourth generation. High speed boards that support standards Fast Ethernet.
5. Fifth generation. Gigabit Ethernet, supporting modern network protocols.
6. Sixth generation. 400 Gigabit Ethernet, currently in development. Will begin to be used no earlier than 2020 for home PCs. Sixth generation Ethernet adapters for servers have already appeared (they are used by providers).

There are other parameters by which devices are classified. The main ones are listed below:

• by data transmission medium (wired, wireless);
• by functions performed (implementing the first two OSI levels/first four);
• by topology (similar local networks: tire, ring, star, tree, combined);
• by type of PC (client, server);
• by bus type (ISA, EISA, PCI, MCA).

Species

Although in order for the selection and configuration of the device to be correct, it is advisable to know some of the subtleties and features of the adapters and have all the knowledge system administrator optional. The main types of boards you need to know:

• wired;
• wireless;
• virtual.

They vary in body size and external parameters, can be connected directly to the motherboard or via a USB socket. Otherwise they look similar, representing a cable with a corresponding key for connecting to a computer port. They provide data transmission over a wired network, connecting a PC/laptop and a router. Sometimes sold complete with software(drivers) for various operating systems, but most modern operating systems find and install it automatically.

Wireless

Often a network adapter refers to a wireless type of device. It is small, mobile and universal, it is also called a modem (although they are designed for 3G), but within this variety the concepts are interchangeable. To work with wireless networks - that’s what the network card is used for in this case. Looks like a flash drive, connects to a USB port, configures and searches available points Wi-Fi. A handy thing if the integrated peripheral device breaks down.

Virtual

Designed to create private and secure networks(VPN). They work using special programs, are built on the basis of physical adapters. Installation depends on type virtual card and selected software. For example, in the Windows operating system there is a special “Control Panel” section for configuring the adapter. Another feature of this type of board is the possibility of remote configuration.

The two most important points regarding connection are what type of connector the network adapter uses and what drivers are needed for it to work. There may be several answers to the first question: USB slot, PCI port or ISA bus. The last two options involve connecting directly to the motherboard. In most cases, drivers are detected automatically or are included with the adapter. If not, you need to search for them on the Internet by device model. Full instructions Connecting a wired network card:

1. Buy a device in one of the stores in Moscow, St. Petersburg or any other city in the Russian Federation.
2. Unpack, read the instructions, use it to determine the type of connector.
3. Connect the plug to the desired port of the router and computer.
4. (option a) See automatic installation, wait for it to finish.
   (option b) If there is a disk with drivers, insert and run the program.
   (option c) Find the required software on the Internet (use proven services!), download and run.
5. Go to Control Panel – Device Manager – Network Adapters. The list should display the name of the board. If there is no exclamation mark next to it, everything is installed correctly.

Connection wireless device carried out in a similar way, but in this case only a PC and a USB connector are used. Drivers are installed automatically. After this operation, the computer immediately starts searching available Wi-Fi networks. Conflicts with the OS are possible; to avoid them, you need to choose a device with correct parameters(will be discussed below).

If the network adapter is not listed in Device Manager, it means something went wrong during the connection. But what exactly? Main reasons and ways to solve them:

1. Board fault. Unlikely cause unless there was physical damage. If there were, you need to take it for repair or replace the adapter yourself.
2. Errors in the operating system. Solution: Roll back to the previous restore point. If it is not there, reinstall the system.
3. Driver problems. Solved either similarly to the previous point, or updated in manual mode. You need to download the software from the official website, since dubious services main reason, why the network card for the computer does not support the driver.
4. Intervention of the built-in antivirus Microsoft protection Windows or other. Start the system in safe mode, disable your antivirus and check the operation of the equipment.

What to do if the adapter does not work

Make sure that the computer sees the device; if not, use the instructions above. Check your system for viruses using the built-in OS protection. If the problem persists, check out the following solutions:

1. Run diagnostics on the card through Device Manager. To do this call context menu and find the corresponding item.
2. Remove all adapters from the Device Manager list. Restart your computer/laptop.
3. As Administrator, open command line. Scan the system: type sfc /scannow and Enter.
4. Update or roll back your drivers.
5. Check the board's operation indicators. If they don’t light up or blink, it’s time to contact a service center.

Network adapter price

The higher the generation and capabilities, the higher the cost of the device. But there is no reason to chase the highest price, since the question is not what technology the adapter supports, but also what technology the computer processor can work with. The characteristics can be viewed on the packaging, checked with the seller, or read on the screen by going to the manufacturer’s official website. The price breakdown for Moscow and the region is in the table below:

Question: The laptop does not see the network adapter

Added after 1 hour 21 minutes
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: Settings in bios setup Tell me, if it doesn’t help, then there’s probably a problem with the hardware, it should also be visible there in the boot menu if it’s alive.

Question: Can't see the network adapter

Answer:

Message from kilbuz

where can I find them?

On the website of the motherboard manufacturer it is known

Question: The network adapter fell asleep and cannot wake up

The essence of the problem.
I installed a new clean Windows 7 maximum x64 system. Copied all the necessary data from the folder Windows 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 I did:

• 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 to motherboard completely blacked out

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

Answer:

Message from kloskon

I just don’t understand why this adapter is visible in the BIOS

Because it is flashed in the BIOS. My motherboard has it in the BIOS LPT port, but it’s not on the motherboard at all.

Answer: Well, at the docks I didn't find what was on board wifi adapter. 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 dockets directly state that you must have a wireless network module installed:

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.

Answer: Very strange. I just turned on my laptop. It connected to wifi and works fine. If there are any problems, I'll write them down.

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, while 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 system reboots and network drivers have started to fail. In any games and at any settings, the video card loads like a sewing machine. Asus video card r9 290x dc2 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.
