Where to find the properties of the network card. Network settings

The network adapter is one of the main components of a computer, because it is difficult 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 distribution of the Windows 7 operating system. But time and progress do not stand still: almost eight years have passed since the release of Windows 7, new network controllers and even methods have appeared data transfers, and with them new network adapters. The use of such components requires additional settings both at the stage of OS installation and during its operation.

Why configure a network card in Windows 7

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

  • fine-tuning Wi-Fi in operating conditions with a large number of 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 configuration of network parameters;
  • installation and configuration of long wireless communication channels using RadioEthernet adapters.
The wireless adapter provides communication at a distance of up to two kilometers

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: viewing the “Network Adapters” branch in the “Device Manager” system utility or analyzing the contents of the network connections in the control panel.


Or open Device Manager using the command line:


If you have installed software packages for working with a 3G modem, VPN clients or virtual machines, then both the “Device Manager” and “Network Connections” will additionally display software network cards created by these programs.

Forcibly turning off such adapters can lead to the most unpredictable consequences, including the inability to boot the PC.

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

For laptops, turning network interfaces on and off is available using a key combination; for desktop PCs, using the BIOS or Control Panel settings.


Windows 7 supports the vast majority of network cards. Moreover, most modern network equipment is designed specifically for Windows, with all the ensuing problems, because Windows is not famous for its stability. However, Microsoft promptly solves most of the problems that arise with network equipment, honor and praise to them, but those that inevitably arise will be discussed in detail in this article.

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

Here are examples of such tasks:


How to view 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 by opening Device Manager using the Run window:


Enabling a network card, including using the BIOS

Read the instructions for all BIOS versions in the article -

On laptops, turning the network interface on and off is done by pressing a key combination; 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 a network driver on Windows 7, including without the Internet

Since the network adapter is equivalent to the Internet, its absence makes it very difficult to download a driver to the network card. The issue is resolved by pre-recording drivers onto media.

  1. Drivers are downloaded and written to a flash drive, CD, etc.
  2. The media is connected to the PC.
  3. After this, the “Device Manager” opens using the “Run” window (called by pressing the “Win ​​+ R” keys), in which the “devmgmt.msc” command is entered.

  4. There is a section “Sound, game and video devices”, a subsection “Unknown device”, which has not yet been installed. You need to start installing drivers for an unknown device (future network adapter) after selecting it with the right mouse button and selecting “Properties” in the drop-down menu.

  5. Left click - “Update”.

  6. Manual installation is selected.

  7. The path to the media with drivers is registered or specified.

  8. Finally, the installation begins. It takes no more than a couple of minutes.

The network card without drivers was located in the "Device Manager" under the "Unknown Devices" section. After the update, it takes its rightful place - in “Network adapters”.

Setting up a network connection in Windows 7

Although companies providing Internet services prefer to configure their clients' network equipment themselves, sometimes it is necessary to carry out more advanced configuration. This is typical for computers with multiple adapters.

To do this:

  1. Go to the Start context menu and open Control Panel.

  2. In the “View” category, set the value to “Category”, find and open the “Network and Internet” section.

  3. Click on the "Network and Sharing Center" link.

  4. Click on the "Change adapter settings" link.

  5. Right-click on the network connection shortcut and select “Properties”.

  6. Check the box “Internet Protocol Version 4 (TCP/IPv4)” and click on the “Properties” button.

  7. Check the box “Use the following IP address” and fill in the fields with data.

    Note! The fields and “Default gateway” are in the agreement with the Internet provider, the remaining fields contain the same values ​​for all users.

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


It is easy to see the adapter parameters and its MAC address thanks to system programs.

To do this:


How to reset all network driver settings?

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



Is it possible to create two network cards?

Many users are thinking about getting a second network card. Physically, there are no problems here: most laptops and computers support a 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 card, which distributes Internet traffic no worse than physical traffic.

It is possible to install such a virtual card in the Windows system itself:

  1. In the Start menu, type “manager” in the field, open “Device Manager”.

  2. In the “Device Manager”, click on the “Network adapters” section, select “Actions” in the top menu, and select “Install old device” from the drop-down menu.

  3. The installation wizard will open. You need to select the manual option to gain access to the list of drivers for all devices.

  4. Scroll through the categories, highlight Network Adapters, and click Next.

  5. Then click on the “Microsoft” item and add “Microsoft loopback adapter” or “Microsoft loopback adapter”, which will then appear in the network connections window.

  6. Confirm. The network adapter should now appear in Network Connections.

Complete reset of network driver settings

If your Internet has been interrupted or most of the Internet pages cannot be opened, then resetting all parameters and the TCP/IP stack can be an excellent solution to this problem.


Disabling a network card

To disable the network adapter, the best way is to use the most standard and convenient Windows tool for keeping all such equipment - the Device Manager. Do the following:


In this case, the shutdown will occur immediately; you won’t even need to reboot the OS.

Important! After the adapter is disconnected, the Internet connection will be severed along with it and a disconnection from the local network will occur. Therefore, it is recommended to finish all your Internet activities in a timely manner before disconnecting the network card.

The network adapter does not have valid IP settings

A frequently occurring problem for Windows 7 users is when problems arise with Internet access and the network diagnostic tool displays a message that the network adapter does not have valid IP settings.

In this case, you can first try resetting the router. If you have a wired connection, then disable and then re-enable your network connection in the network connections menu. If this does not help, then you can move on to further steps.

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


Check again to see if the error is still displayed? If yes, then move on.

Step 2. You can try resetting the network settings, namely the IP protocols. It is recommended to reset the TCP/IP protocol stack to factory settings in the most extreme cases, when problems arise as a result of malware, etc. To do this, open a command prompt in administrator mode and enter:


Network card settings are lost

When setting up a network, users may encounter the following situation: when they manually enter an IP address, gateway, DNS, the specified parameters are not saved, but are reset to 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 an antivirus that has firewall functions.

What to do:

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

If this does not help, then do the following:


After doing this, the problem should be resolved.

What to do if there are problems with the network card?

Many plug-in AC adapters, due to their vulnerability to electricity, may temporarily fail during periods of severe thunderstorms or building power outages. In most cases, difficulties arise in situations with wired equipment, since multi-story buildings have long cable runs laid by Internet providers in places that are not intended for this purpose, next to telephone and television cables and high voltage wires. High humidity, dampness and low temperature in this area - all this has an extremely negative effect on the insulation of wires, so breakdowns appear in them .

Sometimes also, in more rare cases, breakdowns occur due to emergency situations such as a major thunderstorm. Network adapters quite often burn out, or users begin to experience difficulties logging into the network. In this case, the equipment will function, but there may be no Internet connection during such periods.

Unfortunately, this problem can only be solved by purchasing another model of network adapter. For a desktop computer, the PCI standard complies, for a laptop - USB and PCMCIA.

It is also not recommended to plug in a network cable into the router and then connect a computer to it, because even if the router breaks down, replacing it will be relatively inexpensive compared to replacing the network card built into the computer (or even the entire motherboard).

Windows 7 does not see the network adapter

When integrated network equipment is not shown either in the “Network Connections” window or in the “Device Manager”, and is not even reflected in the “Unknown Devices” section (which would be explained by the lack of drivers), then most likely there is something wrong with it physically. It is quite possible that some transistors on the network card board have burned out, or a chip has fallen off - in this case, it is more advisable to buy a new card.

Video - How to configure a wired network card on Windows 7

Good afternoon, Friends! I am very pleased to welcome you to our educational Internet portal https://site. We continue our conversation about setting up a home network. The topic is broad, but interesting and very important.

Today we will be engaged in network education or network settings. In order to be able to set up a home network yourself, you need to gain a minimum understanding of how a local area network works.

We will talk about the terminology of local networks, setting up network adapters, and also take a detailed look at connecting two or more computers to a network.

Let's look at the network connection settings:

1. For Windows XP: Go to the “Start” menu -> “Control Panel” -> “Network Connections”. If your computer has a network card, a network connection icon will appear in the window that opens. Right-click on it and select “Properties” from the menu that opens.

2. For Windows 7: Go to the “Start” menu -> “Control Panel” -> “Network and Internet” -> in the first item “Network and Sharing Center” select the sub-item “View network status and tasks” –> click on the “Local Area Connection” link and then the “Properties” button.

In the list box that appears, select “Internet Protocol (TCP/IP) (version 4, if specified)” and click on the “Properties” button.

A window will open in which the main ones will be displayed.

adapter network settings

– a certain formal designation of your computer in the global or local information space. Most likely, the network we create will operate using TCP/IP (Transmission Control Protocol/Internet Protocol).

A protocol is a set of standard algorithms and rules in accordance with which data is exchanged on a network.

In accordance with the operation of the TCP/IP protocol, each network device is assigned a unique IP address. It consists of 32 bits (or 4 bytes), which are written as four decimal numbers in the range 0-255, separated by dots, for example: 192.168.0.10.

Please note that addresses 0.0.0.0, 127.0.0.1 and addresses ending in 0 and 255 are reserved for service purposes and cannot be assigned to network devices.

When setting up an Internet connection, pay attention to the IP address input field: if your provider has provided you with an IP address, then enter it in the appropriate field, but if it was not provided to you, then simply select “Obtain an IP address automatically.

2. Subnet mask. As a rule, a large network is divided into subnets, each of which is assigned its own unique address, like a separate computer. The full IP address, which we discussed above, contains information about both the address of a specific host and the subnet address.

To separate these sections from one IP address, you need to know the subnet mask. It also consists of 32 bits and takes the value 0 or 1. If you superimpose a subnet mask on an IP address, then the numbers under the ones will mean the subnet address, and under the zeros the address of a specific node. The subnet mask is written the same way as an IP address, four numbers separated by dots, for example: 255.255.255.0.

For reference, computers can only be connected to a network without the help of a router if they are on the same subnet (or have the same subnet address). If the subnet addresses differ by at least one, then information will not be transferred between them.

3. Types of IP addresses and default gateway. As you already understand, the number of unique IP addresses on the Internet is limited, and the number of computers wishing to access the World Wide Web is growing every day. It was decided to divide the addresses into private and public.

  • Public IP addresses can be connected to the Internet directly. They are visible to every computer on the Internet. To get a public IP address, you need to pay money. Pleasure is not cheap. As a rule, such addresses are distributed to providers and dedicated servers, and sometimes to clients.
  • Private IP addresses are addresses that are not visible from the Internet. They are assigned to computers located on subnets connected to the Internet through a router. A router is a device that connects two subnets: local and global (Internet), and therefore has at least two network ports (IP addresses): public (for connecting to the Internet) and private (for working within the local network). Because Since subnets do not interact with each other, the same addresses can be repeated many times in different subnets.

To create a home network, it is best to use private IP addresses. A common option is to use an address like 192.168.x.x, where x is a number from 0 to 254.

4. DNS servers. We looked at what an IP address is. But everyone will probably agree that it is difficult to remember so many numbers. Which is easier to remember: 94.100.191.204 or mail.ru? Of course, it is easier to remember the letter address of the site (domain name). To replace IP addresses with understandable nominal values, special servers were invented - DNS servers. If the IP address changes, the DNS server is immediately informed about this, and your access to the site remains under the same domain name.

To set up Internet access, you must specify the IP address of the DNS server (usually it is issued by your provider or is assigned automatically). If this is not done (or the DNS server stops working), then to access sites you will have to specify their IP addresses.

home network for two

If you need to quickly connect two computers to a network (for example, to transfer information, create a backup copy, or just to play), then it is not at all necessary to buy a router or switch. We will consider two connection options:


I will not consider setting up wireless access in this article. We will dwell on this option later, when considering the settings of routers.

Having selected the type of cable connection, you can proceed to the network adapter settings.

First of all, make sure that the computers are in the same workgroup, in the same address range and with different network names. Let's see how it's done:

Next, you need to set IP addresses and a subnet mask (the subnet mask is set automatically when the IP address is specified) for each computer. We discussed how to choose IP addresses above. Let's see how the IP address is configured:

If you connect several computers to a network using a switch (network switch), then repeat the above settings on each computer on the network.

network troubleshooting

1. The first thing you should pay attention to when troubleshooting a network is whether the network connection is established. Those. is there a physical connection between the computers (are the network cables connected to the network adapters and network devices such as a router, is the Wi-Fi wireless adapter turned on, for example on laptops it is turned off with a special key combination). It is also necessary to determine whether the network adapter is working properly. As a rule, sometimes it is enough to see if the yellow-orange diodes of the network connector blink when the cable is connected.

2. It is necessary to check that IP addresses are not repeated in a given subnet. All computers must have different addresses so that there are no conflicts when exchanging data.

3. Make sure the subnet address is correct. Those. you need to check that the subnet mask on all network adapters is set to the same.

4. Check that the same group is specified in the computer properties (we talked about this above).

5. If a specific site has become unavailable, this does not mean that the network has disappeared; perhaps the DNS server has failed. Check other sites. To control the operation of the DNS server, enter 94.100.191.204 in the address bar of the browser instead of mail.ru. If the site loads, then the DNS is definitely faulty.

Before setting up a Wi-Fi router. You need to set up your computer and check the type of Internet connection your provider uses. Content:

Consider the Windows XP operating system

To determine the type of connection to the boarding school (there are 3 types: PPPoE, Dynamic IP, Static IP). Go through

Start → Control Panel (click “Switch to Classic View”) → Network Connections. (Fig.1)

Next, if you see a window like in (Fig. 2), and where it says “the name of your provider,” there is the name of your provider. This means your connection type is “PPPoE”. You need a Login and Password (obtained from your provider). Let's start connecting the Wi-Fi router.

Define “Dynamic IP”. After the action with “Fig. 1”, right-click on the “Local Area Connection” shortcut and select “Properties” from the drop-down menu. In the window that appears, select the “Internet Protocols TCP/IP” protocol and click the “Properties” button - a new window will appear. If in the properties “Internet Protocols TCP/IP” there are dots opposite the inscription “Obtain an IP address automatically”, then the connection protocol is DHCP (Dynamic IP). See “Fig. 3”. Let's start connecting the Wi-Fi router.

“Static IP” differs from “Dynamic IP” only in that in “Properties: Internet Protocols TCP/IP” there is a dot opposite “Use the following IP address”, and in the cells opposite the inscriptions “IP address”, “Subnet mask” and “Main Gateway”, numerical values ​​have been entered, the connection type is Static IP (Static IP). See (Fig. 4). We write down the numbers that you have written, move the dot to opposite the inscription “Obtain an IP address automatically”, click “OK” in In the “Local Area Connection – Properties” window, click “OK”. Let's start connecting the Wi-Fi router.

Consider the Windows 7 operating system

Start → Control Panel (select “Small Icons”) → Network and Sharing Center. (Fig. 5). Then select “Change adapter parameters” (Fig. 6)

The connection type is “PPPoE”. It is determined in the same way as on Windows XP. See (Fig. 7). You need a Login and Password (obtained from your provider). Let's start connecting the Wi-Fi router.

Define “Dynamic IP”. After the action with “Fig. 5,6”, right-click on the “Local Area Connection” shortcut and select “Properties” from the drop-down menu. In the window that appears, select the protocol “Internet Protocols version 4 (TCP/IPv4)” and click the “Properties” button - a new window will appear. If in the properties “Internet Protocols version 4 (TCP/IPv4)” there are dots opposite the inscription “Obtain an IP address automatically”, then the connection protocol is DHCP (Dynamic IP). See “Fig. 8”. Let's start connecting the Wi-Fi router.

“Static IP” differs from “Dynamic IP” only in that in “Properties: Internet Protocols version 4 (TCP/IPv4)” there is a dot opposite “Use the following IP address”, and in the cells opposite the words “IP address” “Subnet mask” and “Default gateway” entered numerical values, connection type - Static IP (Static IP). See (Fig. 9). Write down the numbers that you have written, move the dot to opposite the inscription “Obtain an IP address automatically” press “OK” in the “Local Area Connection – Properties” window, click “OK”. Let's start connecting the Wi-Fi router.

A network card or network adapter is needed to create a local network, with which you can connect several computers to each other, as well as to connect your computer to the Internet. Sometimes the card starts to work incorrectly, but you can restore it yourself using standard Windows 7 tools.

When to configure an adapter manually

You need to update drivers or change card settings if you have problems connecting to the local network or connecting to the Internet. Please note that such problems are not always caused by the network adapter, but sometimes it is because of it that errors occur that block access to the network.

How to find out the adapter model

The first thing to do is check whether the card is connected to the computer and whether it is recognized by it. The adapter is included with all laptops and computers by default, so if you didn’t assemble your device piece by piece yourself, you shouldn’t think about its absence. But there are times when the wires going to it become disconnected or come off.

A network card (or network adapter) is a device that allows a computer to communicate with other devices. On modern PCs and laptops, the components of this device are integrated into the motherboard.

You will need to open the computer case and check this only if the network card is not visible in the “Device Manager”:

Card activation

If the network card is connected but not enabled, it must be enabled manually. There are several ways to do this. If the card is not damaged, turning it on will not cause errors.

Via "Device Manager"

The previous section described how to view the card model through the “Device Manager”. Find the adapter you need and right-click on it and select the “Enable” function. If the card is successfully turned on, the down arrow icon will disappear from its icon.


Click on the “Enable” button in the “Device Manager”

Using the Control Panel

  1. Using the Start menu or any other method, launch the Control Panel on your computer. Open the “Control Panel”
  2. Go to Network and Sharing Center.
    Go to the “Network and Sharing Center”
  3. Click on the sub-item “Change adapter settings”.
    Click on the sub-item “Change adapter settings”
  4. A list will open, which will most likely contain several cards. One serves as a connection to the wireless network, and the other serves as a connection to the wireless network. There may be additional adapters in the list. Select the one you need and right-click on it and select the “Enable” function. Wait until activation is complete: the red cross icon on the card icon should disappear.
    Click on the “Enable” button to activate the adapter

Via BIOS

If the card cannot be activated using the previous two methods, then perhaps this can be done through the BIOS settings.

  1. Entering the BIOS is done using the Delete key, which must be pressed when turning on the computer. Perhaps the key that activates the BIOS will be different: this will be indicated in the hint that appears in one of the corners of the screen when the logo appears. If you find out the model of your motherboard, you can find on the Internet the button responsible for entering the BIOS.
    Enter the BIOS by pressing the Delete key
  2. The design and location of BIOS items and sections may differ depending on its version and motherboard model, but the following algorithm of actions is approximately the same for all versions. Go to the "Advanced" tab.
    Open the “Advanced” tab
  3. Go to the “Onboard Devices Configuration” subsection.
    Open the subsection “Onboard Devices Configuration”
  4. To enable the card, set the “Onboard Lan” line to “Enabled”. "Disabled" means the card is disabled.
    Set the “Enabled” parameter for the “Onboard Lan” line

Video: how to enable a network card in Windows 7

You can disable an extra card using the same methods that allowed you to enable it: through the “Device Manager”, “Control Panel” and BIOS. Only in the last step of the method through the “Device Manager” you need to click the “Disable” or “Delete” button, in the “Control Panel” click the “Disable” button, and in the BIOS change the value from “Enabled” to “Disabled”.


Disable the card through the “Control Panel”

Updating and installing drivers

Drivers are necessary to ensure that the card does not conflict with other components and fully performs all its functions. Usually they are installed automatically when you first connect the computer adapter, but sometimes the drivers fail or become outdated. In both cases, you need to reinstall them yourself. This is done through the “Device Manager”.

Automatic update

The positive side of this method is that you will not need to search for drivers manually, the negative side is that you will need an Internet connection, which may not be available if the network card does not work. But if you have the opportunity to connect to the network, you can update the drivers in the following way:


Manual update

The advantage of this method is that you can download the card drivers manually from another computer that has Internet access, and then transfer them to yours and install them. It is recommended to download card drivers strictly from the official website of the company that created it.


What to do if drivers are not installed

If at any stage errors occur that prevent you from installing drivers, you must remove the adapter from Device Manager and restart the computer.


Removing the card from the “Task Manager”

After the reboot, open the list of connected devices again, and in it there is the “Other devices” sub-item. It will contain the “Network Controller”, which is your card. Install drivers on it using one of the methods described above.


The network controller is located in the “Other devices” sub-item

If you want to find out the physical address, IPv4 parameters, gateway address and other possible information about the adapter, then follow these steps:


Additional method

You can also find out the card parameters through the “Command Line” using the “ipconfig /all” command. “Command Prompt” can be found by going to “Start” - “Accessories” - “Command Prompt”. Running this command brings up information about all physical and virtual adapters recognized by the computer.


Run the command “ipconfig /all” to obtain information

How to change card settings

The previous paragraph described how to view information about the network adapter. But you can not only see it, but also change it by following these steps:

Updating the network card

The only way to update a network card is to install more recent drivers on it, in which the developers have corrected some previously made errors. New drivers are installed directly on top of the already installed ones. If you cannot install on top, you should remove the device, restart the computer and repeat the procedure. How to do this is described in the section “Updating and installing drivers”.

Can I use two cards?

Two network cards can work simultaneously and relieve each other if one of them is aimed at working with Internet traffic, and the second is aimed at working with a local network. To do this, you need to correctly set the IP, DNS and router parameters for both adapters.

Resetting the adapter

You can reset the adapter settings, namely TCP/IP and DNS, using standard Windows tools or using a third-party program from Microsoft. Conditions under which a reset must be performed:

  • Internet connection speed is low or unstable;
  • files are downloaded broken, this happens due to the same instability of the Internet;
  • When connected, the Internet works fully, but after a few minutes problems begin;
  • Manually changing the adapter settings led to other problems with the Internet.

Standard method

Launch “Command Prompt” by going to “Start” - “Accessories” - “Command Prompt”, and enter the commands “netsh int ip reset c:\resetlog.txt”, “netsh int tcp reset” and “netsh winsock reset” which will perform a factory reset. Done, the registry branches and system files will see changes, and you may need to restart the computer.


Execute the commands “netsh int ip reset c:\resetlog.txt”, “netsh int tcp reset” and “netsh winsock reset” in the “Command Line”

Through a third party program

You can download the NetShell program from Microsoft, which does not require installation, from their official website. Once you launch it, follow the instructions that appear on the screen to reset all changed settings.

Solving adapter related errors

During setup or use of the adapter, the errors described below may occur, which will prevent you from using the Internet or local network. Most of them can be fixed without replacing the card.

The card does not have valid IP settings

You may encounter a similar error when setting IP parameters or scanning a network module using standard Windows tools designed to automatically resolve errors.

Manually obtaining settings

If you have not changed the settings of the adapter, that is, it obtains an IP address automatically, then manually requesting an IP address may fix the problem:

Reset settings

Resetting settings to default values ​​is the most reliable way. How to do this in several ways is described in the section “Resetting the adapter settings”.

Manual adapter configuration

If the previous methods did not help, you should try setting the settings yourself:

Error "This device cannot start"

This error appears in the “Device Manager” not only with the adapter, but also with other connected devices, and has code 10. To fix it, you need to update the card drivers. How to do this is described in the “Updating and installing drivers” section.

The adapter does not work, does not install, or does not appear

If the adapter does not work, does not install or is not displayed, then the reasons may be the following:


Changed map settings disappear

If, after you close the window with the changed settings or restart the computer, all the changes you made disappear as if you never made them, then there are two ways to solve this problem: set the settings by running commands and change the incorrect values ​​in the registry.

Making changes via the Command Line

Launch “Command Prompt” with administrator rights and sequentially execute the following two commands: “route delete 10.0.0.0” and “route -p add 0.0.0.0 mask 0.0.0.0 X”, in the second command “X” is the IP of your router, which usually looks like "192.168.0.1", but in your case it may have a different meaning.

Changing registry settings


A network adapter is needed to connect to the Internet and other computers. If it does not work or is not displayed, check its connection to the computer with wires, and then the status of its drivers and settings. Don't forget to make sure that the network card is enabled in the BIOS.
