How to connect a network adapter on windows. Network adapter driver - detailed installation instructions. Driver Updater by Carambis

If you have at least once encountered the technical support of an Internet provider, or the support of some program related to a local network or Internet access, then most likely you were asked about configuring the network settings of your computer. For novice users, this is a dark forest, of course. And such a question introduces the poor fellow into a complete stupor. As a result, for the simplest manipulations, you have to call a computer wizard and pay him money. But everything is very simple. In this post, I will talk in detail about the basic network settings in Windows 10.

In the Windows 10 operating system, network settings mean the configuration of the TCP / IP protocol on the network adapter, as well as the settings for accessing the computer from the network (local or global).

1. Internet protocol version 4 (TCP/IPv4)

Click the Start button and enter the words in the search bar:

View network connections

The result should look like this:

We click on the icon from the control panel and we open the "Windows 10 network connections" window:

Select the one you want and right-click on it. The properties window will open. These are the basic network adapter settings in Windows 10:

Now we need to find the parameter IP version 4(TCP/IPv4) and click on it twice with the left button of the rodent. So we get into the configuration of the main network protocol IP. There are two options for setting it up:
1 - dynamic IP address.

This option is relevant when a DHCP server is running in the local area and the computer already receives its IP from it. It is usually used when connecting a PC to a home WiFi router or to a carrier's network. The protocol protocol configuration in this case looks like this:
That is, the system receives all addresses automatically from a special server.
2 - static IP address. In this case, ah-pi needs to be registered statically, that is, this address will be assigned to this particular computer on an ongoing basis. It looks like this:

What addresses should be entered in the fields?
Look, the screenshot above shows an option with connecting to a router or modem with DHCP server turned off.
The gateway IP is the address of the router itself on the network. It will also be used as the primary DNS.
Secondary DNS can be specified by the provider's server, or public DNS servers Google (8.8.8.8) or Yandex (77.88.8.8).
The mask used in home networks in 99 cases out of 100 is a regular 24-bit mask: 255.255.255.0 .
The IP address must be selected from the gateway subnet. That is, if the gateway is 192.168.1.1, then you can take any from the computer from 192.168.1.2 to 192.168.1.254.
The main thing is that he should not be busy with anything else.
Click on OK and close all windows! The main network protocol in Windows 10 is configured.

2. Sharing

The configuration of these network settings is responsible for accessing the computer from the network. To get here, in the Network and Internet section, select your adapter (WiFi or Ethernet) and click on the "Change advanced sharing settings" icon. This window will open:

Here you can see network access settings for several profiles: Private, Guest or all networks. Choose the one that has a mark at the end (current profile).
First comes Network discovery. It is responsible for whether your PC is visible from the network or not. If you are connected to a local network at home or at work, then it is better to leave it on. But when the computer is connected to the Internet directly, then in order to avoid threats and attacks, it is better to disable detection.
Next comes Sharing Files and Printers. If it is enabled, then anyone can connect and use the printer that is connected to your PC. For home network it does not play a role, but in a corporate or public one it would be better to turn it off.
The last options are Connecting a homegroup. It is responsible for guest access from the network to the computer. If you allow Windows to manage connections, access will be through the Guest account. On a home network, this is more convenient. For others, it's better to use Accounts users so that no one can access you.
We save the changes.

These are the main network Windows settings 10, responsible for the network and connecting the computer to the Internet.

If we consider the operation of a network adapter, Wi-Fi module or router, users of Windows operating systems may encounter a situation where such equipment stops working due to failures or reinstallation of the system as a whole. Now the question of how to install a network driver on Windows 7 will be considered. At the same time, we will briefly touch on the main points of installation and subsequent configuration.

How to install drivers automatically on Windows 7

First of all, don't panic. A "rally" of the driver, for example, when reinstalling the "OS" is not some kind of critical situation.

Note that in the process of installing and configuring the system, it automatically installs the most appropriate drivers (programs for their correct operation) for almost all devices known today, including network adapters and related equipment. The very essence of the problem, how to install drivers for such devices on Windows 7, comes down only to waiting for the end of the reinstallation process and the initial setup. True, after the computer boots up at the end of the process, in some cases, the driver database may not be located on the hard drive, but on the Windows installation disk.

Using a driver update

If for some reason the driver of the corresponding equipment was not installed correctly, you first need to check in the "Device Manager", called from the standard "Control Panel", whether the equipment is really not working (in the list it is indicated by a yellow circle).

Here you can do it in the simplest way: in the context menu, use the driver update command directly or go to the properties section, where you select the button of the same name (this applies to all systems, including even XP).

The system will search for the most suitable driver and report its successful installation or give a notification that the driver is already installed. But the most suitable driver is often not the best. best solution. Therefore, you should use the choice of the place from which the installation will be made.

In this case, the installation tool is useful Windows disk. However, for example, if the user is not dealing with a desktop computer, but with a laptop, in solving the problem (Windows 7), you need to use a special driver disk, which is mandatory when buying a device. You understand that, unlike manually assembled desktop computers, a laptop has a standard manufacturer's configuration that cannot be changed upon sale.

Here, the disk is simply inserted into and then the location of the desired driver installer is specified when the system is requested.

Removing the device from the system and reinstalling

If this option does not suit someone, the question of how to install network adapter drivers on Windows 7 can also be solved by removing the device from the system.

When Windows restarts again, detect the device automatically, after which you can use the method with the original driver disk.

But you can also do it manually. You need to browse the folders on the optical media and select from there in the folder indicating the corresponding equipment a special driver installation file (usually these are files with the .inf extension). You can install it into the system by calling the context menu (right click) and using the install command.

How to install WiFi drivers on Windows 7

Regarding built-in modules wireless communication and routers, in principle, there is nothing difficult to install drivers.

Based on the foregoing, you can use all the methods described, but, as a rule, Wi-Fi modules are automatically detected by the system, and drivers for routers can be found on accompanying optical media. The installation process is practically no different from the standard one. Another thing is when you need to configure the equipment so that it works correctly.

Setting up a router, Wi-Fi and LAN connection

For routers, access to the settings is used in the form of entering the browser through the address 192.168.1.1 or 192.168.0.1 (depending on the model - this address can be found on the nameplate on the back of the router, in the same place - the login and password for entering), where the parameters are written provided by the provider.

When all operations are completed, the enabled Wi-Fi module will automatically detect the presence of a wireless network, of course, provided that the preliminary installation of a new connection has already been made. The module itself is enabled by default. If it is disabled, you can enable it by combining the Fn button with one of the function keys. For example, on Fujitsu laptops, this is Fn + F5. The module will require a login password, if any, and then connect.

By the way, it is recommended to specify automatic address acquisition in the TCP / IP settings for cable and wireless connections. However, if we are talking about very it may be that some parameters will have to be entered manually. You can get them from your system administrator.

Outcome

In conclusion, it remains to be said that the question of how to install network device drivers on Windows 7, in general, is not difficult to solve. For only one problem can be noted, when there are several in the system that can cause a hardware conflict. In addition, if you don’t have the original driver disk at hand, you can find out the brand of equipment and its manufacturer, and then using another computer connected to the Internet, go to the manufacturer’s official website and download latest version drivers, taking into account the installed "OS" (in our case, Windows 7 32 or 64 bits).

Note: in most cases, manually configuring the network adapter is not required, as our network provides automatic TCP / IP settings for computers. Follow this instruction only if there are problems in the computer network.

1. Go to "Control Panel": open the menu "Start" and select the item "Control Panel".

2. If the window does not look like the one shown in the figure below, then switch the view to « small icons», selecting the appropriate item in the menu "View". Go to "Network and Sharing Center".

Important!

Don't use unload functions Offloading IPsec Tasks or offload TCP Chimney. These technologies are obsolete in Windows Server 2016 and may adversely affect server and network performance. Additionally, these technologies may not be supported by Microsoft in the future.

For example, enabling segmentation offloading may reduce the maximum sustained throughput of some network adapters due to limited hardware resources. However, if bandwidth reduction would not be a limitation, you should enable offload features even for this type of network adapter.

Note

Some network adapters require offloading to be enabled separately for sending and receiving paths.

Enable Scaling (RSS) for Receive-side Web Servers

RSS can improve web scalability and performance when the number of network adapters is less than the logical processors on the server. When web traffic passes through RSS-enabled network adapters, incoming web requests from different connections can be processed by different CPUs at the same time.

Note that due to the RSS and hypertext transfer important protocol (HTTP) load balancing, performance can be severely degraded if non-RSS-enabled network adapter web traffic is on a server that supports RSS-enabled adapters. In this case, you must use network adapters that support RSS, or disable RSS in the properties window of the network adapter additional properties tab. To determine whether an adapter is RSS-enabled, you can view the RSS information on the properties of the network adapter additional properties tab.

RSS Profiles and RSS Queues

The predefined default RSS profile is NUMA Static, which changes the default behavior of previous versions of the operating system. To get started with RSS profiles, you can review the available profiles to understand when they are useful and how they apply to your network or equipment.

For example, if you open Task Manager and look at the logical processors on the server that they are underutilized by receiving traffic, you can try increasing the number of RSS queues from the default value of 2 to the maximum supported by the network adapter. The network adapter may have settings to change the number of RSS queues in the driver.

Increasing resources for network adapters

For network adapters that allow you to manually configure resources, such as receive and send buffers, you should increase resource allocation.

Some network adapters have small receive buffers to conserve dedicated memory from the host. This leads to packet loss and performance degradation. Therefore, for heavy reception scenarios, it is recommended to increase the receive buffer value to the maximum.

Note

If the network adapter doesn't provide it manually, it either configures them dynamically for resources, or resources are set to a fixed value that cannot be changed.

Enable interrupt control

For interrupt management, some NICs offer different interrupt levels, buffer pooling options (sometimes separate for the receive and transmit buffer), or both.

It is recommended to control interrupts for CPU-bound workloads and consider a balance between saving host CPU and latency and increasing savings in host CPU due to more interrupts and lower latency. If the NIC does not handle interrupts but does provide pooling buffers, increasing the number of pooled buffers allows buffers to be pooled for sending or receiving, which improves performance.

Performance Tuning for Low Latency Packet Handling

Many network adapters allow settings to optimize latency caused by operating system. Latency is the time between processing an incoming packet by a network driver and sending that packet back. This time is usually measured in microseconds. For comparison, the transmission time of packets over long distances is usually measured in milliseconds \ (larger \ order). This setting does not reduce the time spent per packet during transmission.

The following are some suggestions for microsecond networks for performance tuning.

Good afternoon, dear readers and guests of the blog site, we continue our troubleshooting of operating systems of the Windows family and next in line is such a network error " To configure TCP/IP, you must install and configure the network adapter". You can meet her both in Windows 7 and in the freshly installed Windows 10 fall creators update in any case, it will be solved the same way everywhere, since Microsoft a large number of errors, just migrates from old systems to new ones, it’s already started and there’s nothing to be done about it.

Cause of error

To be honest, I didn’t hear a clear description of the reason from Microsoft, its official answer boiled down to the fact that you allegedly changed one network adapter to another, the first one didn’t really leave the system and weighs in Windows equipment, so you catch yourself in the settings of the network adapter, the error "To configure TCP / IP, you must install and configure the network adapter." As a result of which it does not work for you the local network, you cannot get an ip address from your DHCP server and you will no longer be able to work on such a computer. In my case, I did not change anything, since on my motherboard, two built-in network cards, sorry Microsoft.

It looks like this in the properties of the network adapter.

In the notification area, the network adapter icon is marked with a warning sign.

Methods for solving the error

The easiest way is to reset the TCP / IP network settings, I already talked about this in these publications:

I advise you to read it, it will take you a couple of minutes.

If this method does not suit you, then you need to open the Device Manager snap-in, the universal method for opening it is to press the Win and R key combination and enter devmgmt.msc. (look for the link on the left)

In the Windows Device Manager, we find the section with network adapters and among the list of equipment we find ours,

if suddenly it is not there, with a high probability it is hidden, you can find hidden devices using this method. On the View tab, find "Show hidden devices"

Now update the configuration, and your Windows 10 or other operating system will automatically detect all relevant hardware and the error "In order to configure TCP / IP, you must install and configure a network adapter" will disappear. Now you can freely use your computer.

I showed you the solution, but I would also like to dwell on some optimization points:

• Check your computer for viruses

It seems to be simple advice, but many people do not do the basic things when operating their operating system.

A network adapter is one of the main components of a computer, because it's hard to even imagine a PC that is not connected to the Internet. Microsoft is aware of this, so support for the vast majority of network cards is already included in the operating system distribution. Windows systems 7. But time and progress do not stand still: almost eight years have passed since the release of Windows 7, new network controllers and even data transfer methods have appeared, and with them new network adapters. The use of such components requires additional settings both at the OS installation stage and during its operation.

Why configure a Windows 7 network card

Change basic settings A network adapter may be needed to expand the range of tasks performed by a network client computer:

• fine-tuning Wi-Fi in the field with large quantity wireless devices (apartment building, office building);
• installing drivers for a network card that is not supported by the OS out of the box;
• some Internet providers (VPN, pptp, wimax) require additional network settings;
• installation and configuration of extended wireless communication channels using RadioEthernet adapters.

How to find out what kind of network cards are installed in the system

You can find out the presence and number of active network adapters on your PC using one of the following methods: view the "Network adapters" branch in system utility"Device Manager" or analyze the contents of the network connections of the control panel.

Or open the Device Manager using the command line:

If you have installed software packages work with a 3G modem, VPN clients or virtual machines, then both in the "Device Manager", and in " Network connections» will additionally display software network maps created by these programs.

Forced shutdown of such adapters can lead to the most unpredictable consequences, up to the inability to boot the PC.

How to enable or disable the network card (including using the BIOS)

For laptops, enabling and disabling network interfaces is available using a key combination, for stationary PCs - using BIOS settings or the Control Panel.
