How to enable or disable a network adapter using Windows PowerShell

The first thing to be done is to find out the name of the network adapter, for this on the name of the administrator and run the following command:

The name of the network adapter is displayed in the Name string. Remember the name of the network adapter that you want to enable or disable (in this Ethernet example).

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

Disable-Netadapter -Name " Name of network adapter"-Confirm: $ False

Replace Name of network adapter In the command above the actual name of the network adapter that you want to disable (for example Ethernet). In this example, the command is as follows:

Disable-Netadapter -Name "Ethernet" -Confirm: $ FALSE

To enable the necessary network adapter, in the PowerShell console, execute the following type command:

Enable-Netadapter -Name " Name of network adapter"-Confirm: $ False

Replace Name of network adapter In the command above the actual name of the network adapter that you want to enable (for example, Ethernet). In this example, the command is as follows:

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

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

This method uses the Netsh command line utility commands (Network Shell - network shell) which allows you to display or change the computer network configuration.

First of all, we need to find out the name of the network interface, for this on the name of the administrator and run the following command:

netsh Interface Show Interface

Remember the name of the network interface that you want to enable or disable (in this Example Ethernet).

netsh Interface Set Interface "Interface Name" Disable

Replace the interface name in the command above the actual network adapter name that you want to disable (for example Ethernet). In this example, the command is as follows:

netsh Interface Set Interface "Ethernet" disable

netsh Interface Set Interface "Interface Name" Enable

Replace the interface name in the command above the actual network adapter name that you want to enable (for example Ethernet). In this example, the command is as follows:

netsh Interface Set Interface "Ethernet" Enable

How to Enable or Disable Network Adapter Using WMIC commands

This method uses the Windows Management Teams.

First, you first find out the number of the network adapter index, for this, on behalf of the administrator and execute the following command:

Remember the Network Adapter Index number (in this example 8)

To disable the network adapter, execute the following type:

wMIC Path Win32_Networkadapter WHERE INDEX \u003d index number Call Disable

Replace the index number in the command above the actual number of the network adapter that you want to disable (for example 8). In this example, the command is as follows:

wMIC Path Win32_Networkadapter WHERE INDEX \u003d 8 CALL DISABLE

To enable a network adapter, execute the following type:

wMIC Path Win32_Networkadapter WHERE INDEX \u003d Call Enable Index Number

Replace the index number in the command above the actual number of the network adapter that you want to enable (for example 8). In this example, the command is as follows:

wMIC Path Win32_Networkadapter WHERE INDEX \u003d 8 CALL ENABLE

If you at least once come across the technical support of the Internet provider, or with a support of some program associated with a local network or Internet access, then most likely you have asked about the configuration of the network parameters of the computer. For novice users - this is a dark forest, of course. And such a question enters the poor fellow in the complete stupor. As a result, for the simplest manipulations, you have to call a computer master and pay him money. But everything is very simple. In this post, I will tell you in detail about the main network settings in Windows 10.

In the Windows 10 operating system, the network parameters implies the TCP / IP protocol configuration on the network adapter, as well as configure the access parameters to the computer from the network (local or global).

1. IP version 4 (TCP / IPv4) protocol

Press the Start button and enter the word in the search bar:

View network connections

The result should be like this:

Click on the icon from the control panel and we open the Windows 10 Network Connections window:

Select then from the right and press on it with the right mouse button. The properties window opens. These are the main network adapter settings in Windows 10:

Now you need to find the parameter IP version 4 (TCP / IPv4) And click on it twice with the left button rodent. So we get into the configuration of the basic Network IP protocol. Options for its setting can be two:
1 - Dynamic IP address.

This option is relevant when the DHCP server works in LAN and the computer is already obtained from it. It is used usually when connecting a PC to a home wifi-router or network operator network. The protocol configuration of the protocol in this case looks like this:
That is, all addresses the system gets automatically from a special server.
2 is a static IP address. In this case, Ay-Pi is required to register statically, that is, this address will be fixed precisely behind this computer on an ongoing basis. It looks like this:

What addresses should be inserted into the fields?
See, the screenshot is presented with an option with connecting to a router or a modem that the DHCP server is turned off.
The IP gateway is the address of the router itself on the network. It will be used as the main DNS.
Secondary DNS you can specify the provider server, or public DNS GUGL servers (8.8.8.8.8) or Yandex (77.88.8.8).
The mask used in home networks in 99 cases out of 100 is the usual, 24-bit: 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 the computer can be taken from 192.168.1.2 to 192.168.1.254.
The main thing is that he is not busy anything else.
Click on OK and close all windows! The main network protocol in Windows 10 is configured.

2. Common access

Setting up these network settings is responsible for accessing the computer from the network. To get here to get into the section Network and Internet Select your adapter (WiFi or Ethernet) and click on the "Changing Extended Shared Parameters" icon. This window will open:

Here you can sees the settings of network access parameters for multiple profiles: Private, guest or all networks. Choose the one who has a mark at the end (current profile).
First goes Network detection. He is responsible for whether your PC is seen from the network or not. If you are connected to a local home network or at work, it is better to leave it included. But when the computer is connected to the Internet directly, then to avoid threats and attacks, detection is better disconnected.
Next goes Share files and printers. If it is enabled, then to the printer, which is connected to your PC, will be able to connect and use anyone. For the home network, it does not play roles, but in corporate or public it will be better to turn it off.
Last parameters - Connecting a home group. It is responsible for guests from the network to the computer. If you allow Windows to manage connections, then access will be accessed through the guest account. In the home network it is more convenient. For others, it is better to use user account records so that anyone cannot go to you.
We save changes.

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

Network adapter is one of the main components of the computer, because it is difficult to even present a PC, not connected to the Internet. Microsoft Corporation is in this report, so support for the overwhelming majority of network cards is already included in the Windows 7 operating system distribution. But time and progress are not on the spot: from the moment of release of Windows 7, almost eight years have passed, new network controllers have appeared and even methods data transfer, and with them new network adapters. The use of such components requires additional settings both at the OS installation phase and in the process of its operation.

Why set up Windows 7 network card

Changing the basic settings of the network adapter may be necessary to expand the circle of tasks performed by the network client:

thin setting Wi-Fi in operation with a large number of wireless devices (apartment building, office building);
installing drivers for a network card, the support of which is not provided by OS "out of the box";
some Internet providers (VPN, PPTP, WiMAX) require additional network parameter settings;
installing and configuring extended wireless communication channels using RadioETherNet adapters.

Wireless adapter provides communication at a distance of two kilometers away

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

It is possible to find out the availability and number of active network adapters of your PC using one of the following ways: viewing the "Network Adapters" branch in the Device Manager System Utility or the contents of the control panel's network connections.

Or open the Device Manager using the command line:

If you have installed software packages with 3G modem, VPN clients or virtual machines, then in the Device Manager, and in "Network Connections" software network cards created by these programs will be additionally displayed.

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

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

In laptops, turning on and off network interfaces is available using a key combination, in stationary PCs - using the BIOS or "control panel".

When installing a new router to work with a computer running Windows 8.1, I found that no matter how many times I configured the IP address settings for the network adapter in Windows, the settings returned to "get an IP address automatically". Obviously, it was a sign that some settings of the network adapter are damaged. Therefore, the only solution is to manually remove the damaged Windows registry settings and restore new parameters. That's how it can be done:

Step 1 - Reinstall the power adapter in your PC

Use the Win + R keys combination to open dialog.
In the "Run" dialog box, you need to enter the DevmGMT.msc command and press ENTER. The Device Manager window opens.
In the Device Manager window you need to select your network adapter, then right-click on it and select Delete.

4. After it disappears from the Device Manager, click on the Update Equipment Configuration button - the icon in the toolbar to re-scan the network adapter and install drivers for it.

5. If you use third-party drivers for your network adapter, you will have to reinstall or update these drivers by downloading them from the Internet or using the supplied CD.

Step 2 - Clear Settings in the Registry

1. Use the Win + R keys combination to open the Dialog.
2. In the "Run" dialog box, you need to enter the regedit.exe command and press the Enter key. After that, the registry editor opens.

3. In the Aries registry editor, find and open the HKEY_LOCAL_MACHINE \\ SYSTEM \\ CURRENTCONTROLSET \\ CONTROL \\ NETWORK section.

4. On the right side, select the value of the configuration name, right-click on it and select Delete.

Step 3 - Restore Settings

Open the Windows Control Panel and select the network and the Internet, then the network center and sharing.
On the left, click on changing the adapter parameters.

3. Right-click on your network adapter and select Properties from the menu.

4. The "Properties" window do not change anything. Just click on the "OK" button. This will allow you to restore the configuration of the values \u200b\u200bin the registry.

5. Now you can go and change the adapter values \u200b\u200bas you like. New values \u200b\u200bwill be saved and the configuration will no longer be corrupt.

Windows 7 supports the overwhelming majority of network cards. Moreover, most of the modern network equipment is stuck under Windows, with all the problems arising from here, because Windows is not famous for stability. However, Microsoft promptly solves the majority of problems that arise with network equipment, honor them and praise, well, and those that inevitably arise will dismantle in detail in this article.

First of all: in order to expand the potential range of tasks that the client performs on the network, it is necessary to change the basic parameters of the network card.

Here are examples of such tasks:

How to see a list of available network adapters (network connections) in Windows 7?

The list of available devices on Windows 7 can be seen in two ways:

The second method begins with the opening of the "Device Manager" using the "Run" window:

Turning on the network card, including using BIOS

Read the instructions for all BIOS versions in the article -

On laptops, turning on and off the network interface is carried out by pressing the keyboard key, on desktop computers - through the BIOS menu.

To enable the wireless network adapter on laptops there is a combination "Fn + F12", although some manufacturers make a special key for this function.

Installing the network driver on Windows 7, including without the Internet

Since the network adapter is equivalent to the Internet, its absence greatly makes downloading the driver to the network fee. The question of the preliminary recording of drivers for carriers is being resolved.

Drivers are downloaded and recorded on the flash drive, CD, etc.
The carrier connects to the PC.
After that, the "Device Manager" opens, using the "Run" window (called by pressing the "Win + R" keys), in which the "devmgmt.msc" command is entered.
There is a section "Sound, game and video devices", subsection "Unknown device", which is not yet installed. Installing drivers for an unknown device (future network adapter) You need to start after it is released by the right mouse button and select in the "Properties" drop-down menu.
Click with the left mouse button - "update".
The manual installation is selected.
Prescribed or indicates the path to the media with drivers.
Finally, the installation begins. It takes no more couple of minutes.

The network board without drivers in the Device Manager was located in the section "Unknown Devices". After the update, it falls on its rightful place - to "Network Adapters".

Setting up a network connection in Windows 7

Although companies that provide Internet services prefer to customize customer network equipment independently, sometimes you have to conduct more advanced settings. This is characteristic of computers with multiple adapters.

For this:

Come in the Start Context menu, open the control panel.
In the View "category, set the" Category "value, find and open the" Network and Internet "section.
Click the "Network and Shared Access Control Center" link.
Click the "Changing Adapter Settings" link.
Click the network connection label with the right mouse button, select "Properties".
Put the box to the "Internet version 4 (TCP / IPv4)" item, click on the "Properties" button.
Check to the "Use the following IP address" item, fill in the data fields.

On a note! The fields and the "main gateway" are in the contract with the Internet provider, the remaining fields contain values \u200b\u200bare the same for all users.

How to view and change network card (IP, Mac, other) settings in Windows 7?

See the adapter parameters and its MAC address is easily due to system programs.

For this:

How to reset all network driver settings?

If you want to completely roll back all the settings to the original level, then do the following:

Is it possible to create two network cards?

Many users think about getting a second network fee. Physically there are no problems: most laptops and computers support the second network card. But there are exceptions, as well as damaged slots, as well as netbooks and tablet computers. In this situation, you need to use a virtual fee, which distributes Internet traffic is no worse than physical.

The ability to install such a virtual map is in the Windows system itself:

In the "Start" menu in the Dial "Dispatcher" field, open the Device Manager.
In the Device Manager, click on the "Network Adapters" section, select the "Action" item in the top menu, and from the drop-down - item "Install an old device".
The installation wizard opens. You need to select a manual option, to gain access to the list of drivers of all devices.
Scroll categories, highlight the "Network Adapters" item, click "Next".
Then click on the "Micrsoft" item Add "Micrsoft Loopback Adapter" or "Microsoft Circuit Adapter", which will appear in the Network Connection window.
Confirm. The network adapter should now appear in "Network Connections".

Full reset settings for network drivers

If your Internet has cut off or most of the Internet pages does not open, then a great solution to this problem can be reset all parameters and a TCP / IP stack.

Disable a network card

To disable the network adapter, the best tool is all used the most standard and convenient Windows tool for the content of all such equipment is the device manager. Make the following:

At the same time, the shutdown will occur immediately, it is not necessary to even make the OS reboot.

Important! After the adapter is disabled, the Internet connection will be blocked with it and it will turn off from the local network. Therefore, it is recommended to finish all your affairs on the Internet in a timely manner before turning off the network fee.

Network adapter does not have permissible IP settings

Often the problem of Windows 7 users - this is when problems with Internet access and network diagnostics displays a message that the network adapter does not have permissible IP settings.

In this case, you can first try to make a reset of the router. If you have a wired connection, turn off, and then turn on your network connection again in the network connections menu. If it does not help, you can move to further steps.

Step 1. Update your IP address - this is the easiest method, although it does not always help in this case. To do this, open the "Command Line" (as an administrator) and enter the following commands:

Check again if the error is still displayed? If so, then we go further.

Step 2. You can try to reset network settings, namely, IP protocols. The TCP / IP protocol stack is recommended to be discharged to factory settings in the most acute cases where the problems occur as a result of actions of malicious programs, etc. To do this, open in the administrator mode command line and enter:

Choose network card settings

When setting up a network, users may encounter the following situation: when the IP address, gateway, DNS are manually prescribed, are not stored, and reset to the factory settings, and thus it becomes impossible to change the network settings from automatically receiving addresses from the router. One of the common reasons for this is the incorrect removal of antivirus having a firewall function.

What should be done:

Reset TCP / IP protocol stack to factory settings (above the article indicated how to do it).
Reboot.

If it does not help, then do the following:

After that, the problem must be solved.

What if there are problems with a network card?

Many connected network adapters, due to their vulnerability to electricity, may fail to fail during periods of severe thunderstorms, or electricity interruptions in the building. In most cases, difficulties are manifested in situations with wired equipment, as multi-storey houses have long cable tracks, laid by Internet providers not in all-designed places, adjacent to telephone and television cables and high voltage wires. High humidity, dampness and low temperature in this area - all this is extremely negatively affected by the insulation of the wires, so trifles appear in them .

Sometimes also, in more rare cases, breakdowns arise due to emergency situations like a large thunderstorm. Network adapters are quite often fascinated, or users begin to experience difficulties with the entrance to the network. In this case, the equipment will function, but the connection to the Internet may be absent in such periods.

Unfortunately, this problem is solved only by buying another network adapter model. The desktop complies with the PCI standard for a laptop - USB and PCMCIA.

It is also not recommended to include a network cable in the router, and then connect the computer to it, because even if the router breaks, it will be replaced relatively inexpensively, compared with the replacement of the network card built into the computer (or the entire motherboard).

Windows 7 does not see a network adapter

When the integrated network equipment is not shown in the "Network Connection" window, nor in the "Device Manager" window, and is not even reflected in the section "Unknown Devices" (which would be explained by the lack of drivers), then most likely something is wrong with him physically. It is possible that some transistors overloaded on the network card on the board, or the chip flew off - in this case it is more expedient to buy a new card.
