How to enable a network card on Windows 7. How to install a network adapter

If you have ever encountered technical support Internet provider, or with the support of some program related to the local network or Internet access, then most likely you were asked about setting up the computer's network settings. 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 window " network connections Windows 10":

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, IP needs to be registered statically, that is, this address will be assigned to this particular computer on permanent 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 subnet of the gateway. 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 local network at home or at work, 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 Connection home group . 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.

Note: in most cases manual setting network adapter is not required, because our network provides automatic distribution of TCP / IP parameters 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 protocol (HTTP) important load balancing, performance can be significantly 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, 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 the balance between host CPU savings and latency and increased host CPU savings due to more interrupts and latency reduction. 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 the latency caused by the 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.

This article shows you the steps to enable or disable the network adapter(s) in the Windows 10 operating system

A network adapter (Network Interface Card, NIC) is hardware component a computer that connects a computer to a computer network, known as a network connection, and allows the computer to communicate with other devices on the network.

To enable or disable a network adapter, you must be logged in as an administrator

How to enable or disable a network adapter using Windows PowerShell

The first thing to do is to find out the name of the network adapter, to do this, as an administrator and run the following command:

The Name line displays the name of the network adapter. Remember the name of the network adapter you want to enable or disable (in this example ethernet).

To disable the desired network adapter, run the following command in the PowerShell console:

Disable-NetAdapter -Name" Network adapter name-Confirm:$false

Replace Network adapter name in the command above with the actual name of the network adapter you want to disable (eg Ethernet). In this example, the command looks like this:

Disable-NetAdapter -Name "Ethernet " -Confirm:$false

To enable the desired network adapter, run the following command in the PowerShell console:

Enable-NetAdapter -Name" Network adapter name-Confirm:$false

Replace Network adapter name in the command above with the actual name of the network adapter you want to enable (eg ethernet). In this example, the command looks like this:

Enable-NetAdapter -Name "Ethernet " -Confirm:$false

How to enable or disable a network adapter using the netsh utility

This method uses utility commands command line netsh (network shell - network shell) which allows you to display or change the computer's network configuration.

First of all, we need to know the name network interface, to do this as an administrator and run the following command:

netsh interface show interface

Remember the name of the network interface to be enabled or disabled (in this example, Ethernet).

netsh interface set interface "Interface name" disable

Replace Interface Name in the command above with the actual name of the network adapter you want to disable (eg Ethernet). In this example, the command looks like this:

netsh interface set interface "Ethernet" disable

netsh interface set interface "Interface name" enable

Replace Interface Name in the command above with the actual name of the network adapter you want to enable (eg Ethernet). In this example, the command looks like this:

netsh interface set interface "Ethernet" enable

How to enable or disable a network adapter using WMIC commands

This method uses Windows Management Instrumentation commands.

First, find out the index number of the network adapter, to do this, on behalf of the administrator and run the following command:

Remember the index number of the network adapter (in this example 8 )

To disable the network adapter, run the following command:

wmic path win32_networkadapter where index=Index number call disable

Replace the Index Number in the command above with the actual number of the network adapter you want to disable (eg 8 ). In this example, the command looks like this:

wmic path win32_networkadapter where index=8 call disable

To enable the network adapter, run the following command:

wmic path win32_networkadapter where index=Index number call enable

Replace the Index Number in the command above with the actual network adapter number you want to enable (eg 8 ). In this example, the command looks like this:

wmic path win32_networkadapter where index=8 call enable

When considering the operation of a network adapter, Wi-Fi module or router, users of operating Windows systems may encounter a situation where such equipment stops working due to failures or reinstallation of the system as a whole. Now the question will be considered how to install network driver on Windows 7. 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, it will come in handy installation disk Windows. 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 in the system by calling 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 wifi module will determine the presence wireless network, of course, provided that presetting a new connection has already been made. The module itself is enabled by default. If it is turned off, you can turn it on 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 say that the question is how to install drivers on Windows 7 network devices, in general, there is nothing difficult to solve. For only one problem can be noted, when there are several in the system that can cause a hardware conflict. Also, if you don't have original disc with drivers, you can find out the brand of equipment and its manufacturer, after which, using another computer connected to the Internet, go to the official website of the manufacturer and download latest version drivers, taking into account the installed "OS" (in our case, Windows 7 32 or 64 bits).

Often there is a situation where correct connection router or modem to a PC in the lower corner of the computer monitor there is no "windows 7 wireless network connection" icon. And no matter how much the user switches wires, stubborn "network connections" never appear. In this case, it is necessary to postpone the “cable work” for a while and check (and possibly reinstall) the LAN connection settings.

Windows 7 network connection setup

• 1. Click the left mouse button (then all the time with the left, unless otherwise indicated) the Start menu button.
• 2. Select the "Control Panel" icon.
• 3. In the "Control Panel" click "Network and Internet" - "View network status and tasks" (if you do not see it, switch the view mode to the "Category" view).

4. Go to the "Change adapter settings" menu.

5. Right-click on the "Local Area Network Connection" icon, select "Properties" from the context menu.

6. Double-click to expand the properties of "Internet Protocol version 4 (TCP / IPv4)".

7. We switch the first checkbox to the position: “Obtain an IP address automatically”, the second to “Obtain a DNS address of the north automatically”.

8. If the checkboxes were already in the specified position, then change the first one to the position: “Use the following IP address”.

Set the following values: "IP address": 192.168.1.2, "Subnet mask" 255.255.255.0, "Default gateway": 192.168.1.1; "Preferred DNS server': 192.168.1.1.

Do not forget to press the "OK" button in all open windows to save your settings.

Setting up a network connection in windows 8:

In general, setting the connection parameters here is carried out in the same way. previous version OS. The only caveat: many users do not know how to open network connections in windows 8. Therefore, at this stage, we will dwell in more detail:

1. Right-click on the "Start" menu and in the menu that appears, select "All applications"

2. In the "Applications" menu, click the "Control Panel" icon.

3. Click on the "Network and Internet" icon.

5. Find and click "Change adapter settings" (top left).

Further configuration is carried out similarly to the "seven": follow steps 5 to 8 and check the network connection - the corresponding icon should appear in the lower corner of the monitor.
