How to create and configure a local network

Local Area Network (LAN. Local Area Network). united by a common access computers and devices, usually within one house (an apartment, office), organization or public institution. Such networks are created mainly to simplify data exchange and collaboration.

  • Quick access to shared files between devices
  • data transfer between devices without external storage devices (thumb drives, disks, etc.).п.)
  • opening access to the Internet for all network members, if it is connected to only one computer
  • Managing portable devices from different computers. For example, within the office from any iron you can print on one printer
  • voice and video conferencing, and network gaming.

The principle of creating a local network (at home or in a small business) in any version of Windows is practically the same. The exceptions are complex multi-tiered corporate networks with multiple subnets, proxy servers and VPNs.

Everything that can be connected by cable should be connected by cable. In such a way the possibility of the appearance of problems with the speed and stability of the work of the corresponding client devices is eliminated. The computer that serves the other computers on the network is called a server. The server can be a separate device, as well as any computer. A separate device is more necessary for offices (although not necessary for smaller ones), but for home use you can get by with a computer.

The way to connect two computers via a Wi-Fi router or a switch.

If you have a router or a switch, it is twice as easy to connect two computers. Even if you have a Wi-Fi hotspot, whether you connect the computer with a cord or a wireless Wi-Fi connection is irrelevant. It is the same, as long as the subnet is the same (eg 192.168.1.)

First, you need to check that the workgroup is the same, otherwise the second computer will not see the first. Go to the control panel and select the system.

make, network, computers

Next, see what workgroup you have. If different everywhere, call the same name. To do this we click on change settings.

And change the name. The main thing is that the name is the same on all computers!

So, to connect the computers go to the control panel and select the homegroup.

Next, choose to create a home group.

Next, select which shared folders you want to share.

Next, save the password you will be given. We need it to connect the other computers.

Next, the other computers need to connect to the group. Go to the same control panel. homegroup and see that the computer saw the homegroup. Click join.

Some people think that the connection via wire and via Wi-Fi is different. So, to destroy the myth about connecting two computers with each other via WI-FI, I decided to connect via Wi-Fi and do the same thing.

share the files you want.

Next, enter the password that was given when you opened the group above.

Next, if you want to share files. do the following. Go to Control Panel and the Network and Sharing Center.

Click change advanced sharing settings.

All. Now check. Create a folder, for example I created on the desktop of the laptop (which is connected via wi-fi).

Then right click on it and select the property. Access tab. First sharing, then advanced settings.

Write all or a specific user, then you can put what he is allowed to and press share.

In Advanced Setup, check the box and click ok. If you need advanced rights, the advanced button.

Now we check. On the computer, press start, go to the network. And see his laptop (the computer name I do not bother).

Go in and see the folder I created in my notebook.

Router settings

TP-Link is chosen as the router. The basic methods of connecting to routers are described here. The most important thing for setting up your home network is DHCP, so let’s talk about it in detail.

Start the DHCP service. Enter the starting and ending addresses that you found out with the calculator. Don’t forget to specify IP lease period (this option gives additional security guarantee, as IP of each device changes after a specified period of time). As the default gateway should specify the router itself. Specifying a domain for a workgroup is not relevant. DNS-server in domain networks is specified by domain controller, for a home network it is recommended to use the address (Google DNS server).

Important! The address of the router must be constant!

The Client List option contains a record of each network subscriber, namely the MAC address mapping to the IP address.

In the “List of clients” option we find the records of each network subscriber, namely the mapping of MAC-address to IP-address

“Address Reservation” is used to exclude renting special network components, such as printers.


There are two ways to connect computers via LAN: directly and with a router. In the first method, two computers are connected with a single LAN cable, and in the second method, the cables must be connected to both computers and the router.

Connecting directly

To connect two computers directly, follow the following step-by-step instructions:

    Insert the plug at one end of the LAN cable into the RJ45 network connector of your computer.

Uninstalling a Personal Computer in Windows 10

Despite the fact that in most cases, it is enough to disable the detection of devices in the local network using the method mentioned above in this article, there is no need to keep local connections on your computer, which are not used.

So let’s see how to delete an already created local network that we don’t need.

You can do it in Windows 10 through the registry. To call it, press WinR and in the window that appears type regedit.

Warning, any unauthorized registry modification may harm your computer. You do this at your own risk.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles

There you will find many traces of former network connections with specific names. Simply delete those subsections that tell you that you no longer need the network connections.

We have seen how to create a local network using a network cable and using a wireless connection. Now you can organize connections between your devices at home or at work to transfer information comfortably and quickly.

Hi all! I like to write for people, about the computer field. whether it’s working in various programs or having fun with computer games. I try to write only about things with which I am personally familiar. I love to travel and I believe that only on the road you can truly know yourself.

Connecting Two Computers to a Local Area Network using a LAN Cable

Very often, users look for information on forums about connecting two computers into a local network. This question is asked not only by forum members, but also on websites where the so-called FAQ (question-answer) is implemented. Since connecting computers via LAN cable also raises questions from visitors to the blog, I decided to write a detailed instructional article. It is important to note that we are going to use a LAN cable to connect two computers together in this article, and we will move on to discuss Wi-Fi connectivity in a later article.

As you understand we need a LAN cable crimped with a crossover cable to locally connect two computers. It is worth mentioning that for computers with Ethernet Auto-MDIX interface (media-dependent interface) the type of crimping (direct or cross-directional) does not matter, as the network port is automatically configured. This technology must be supported by two devices.

Nothing is perfect, and in practice it happens that Ethernet Auto-MDIX boxes do not work correctly. To avoid such situations, I recommend that you stick to twisted pair crimping standards and use each type of LAN crimping for its intended purpose. Before connecting two computers together on a LAN make sure that you are using a working and correct type of cable. Read more about where direct and cross-over types are used and how to crimp a LAN cable without crimpers (crimping tools) here.

The length of twisted pair to connect two computers in a local network should not be more than 100 meters. Otherwise the fading of the signal will affect the quality of the network.

You can also use a FireWire (IEEE 1394 or i-Link) cable to connect two computers if both devices (laptop, desktop) have the corresponding ports. If there are no IEEE 1394 ports, you can install a desktop FireWire controller / expansion card for the PCI slot, and a laptop PCMCIA card with i-Link ports. FireWire cables are available in 4 pins (pin) and 6 pins (pin) versions. Depending on the ports of the computers to be connected use the corresponding cable.

So, you have connected two computers using one of the above methods. If you are creating a network connection between the two computers via the RJ-45 connector, the Ethernet controller’s LED must be lit / flashing green (usually located near the RJ-45 connector). If this does not happen, or if only one computer’s LED is lit, check if the cable is properly pressed.

Also make sure that the network adapters are plugged in, their drivers are installed, and that the devices are working properly. And if the indicators on the two computers are lit or flashing, it means that the hardware connection is established and the cable is not broken and is working properly.

If you are using Windows 7 (Windows XP), then usually after connection the computers start to “see” each other and work normally. It depends on the preset parameters. However, if this does not happen, you will need to make some changes to your network connection settings.

Let’s look at a direct connection between two computers over a FireWire or LAN (twisted pair) cable under Windows XP and then see how to connect two computers running Windows 7. It is desirable that the two computers you connect are in the same workgroup.

Connecting two computers in a network under Windows XP.

Access the “Control Panel” via “Start” and click on the “Network Connections” icon. Right-click on “Local Area Connection” and select “Properties” in the context menu.

In the window that opens navigate to “Internet Protocol (TCP/IP)” and move the switch to “Use the following IP-address.

Here we need to enter a network IP address for the computer. For example like this:

That is, you do not have to set “Default Gateway”, but if the computers will not see each other, you may set this parameter as well. After that, click “OK” in all windows.

Do the same on the other computer, but enter a different IP address. For example, like this:

Now you need to establish a connection between the computers (if the connection between personal computers will not be, then restart them). To make sure the settings are correct, go to “Network Connections” and click on the “Local Area Connection” icon. The “Status” window must show “Connected”.

If it says “Connection restricted”, then check if the network connection settings are filled in correctly. With the connection in the operating system Windows XP are solved, now let’s look at how to establish a network between two computers in Windows 7.

Connecting two computers in a network running Windows 7.

Actually, in Windows 7 there isn’t much difference for connecting two computers to the network, but in order to make it clearer for those who use this particular operating system, I’ll describe the sequence of operations specifically for them.

Go to “Start” in the “Control Panel” and select “Network and Internet. Then go to “Network and Sharing Center” and click on “Change Adapter Settings”. Here we are. Right click on “Local Area Connection” and go to “Properties.

Open the shared folders

Right-click at the bottom of the desktop on the right side of the network and select “Network Settings”.

Click on “Status” and select “Control Center”.

Expand one by one all network profiles and in each of them set the dots for “Enable” and “Allow”.

Scroll down the list and in the last item “with password protection” select “Disable”. Click “Save changes”.

Repeat “Steps 1-4” on the other PC.

Sharing resources

If you have created a network for gaming, everything is ready, to exchange files you have to make the directories with them available.

  • Open the window with the folder properties that the second computer will have access to (remote access to files is not allowed).
  • On the “Access” tab, click “Advanced Setup”.
  • Activate the only option in the window that opens.
  • Enter the name of the directory where the second user will see it.
  • Click “Permissions” if you want to give extended permission over the folder.
  • Select “Full access” if you want a second user to be able to delete, save, and modify the contents of the shared directory.
  • Save the configuration and so on for each directory.

In case you have to work in different networks, use NetSetMan to switch between network settings profiles. If one of the network clients has Internet (via modem or phone), you may allow the other one to access it as well:

  • Call the properties of the current connection and go to the “Access” tab;
  • activate the item “Allow other users to use the connection”;
  • Save your changes.

Game over a local network

So, we managed to connect two devices to the same network without Internet, allow them to share files. How to start playing on the LAN?

For this, as a rule, no additional settings to do. We just turn on the game and, if you can play over a local connection, select the appropriate item, and then play on the already created by us.

For different games, the connection to the shared server may be different. Somewhere you will need to enter the IP or name of the PC. For Minecraft, Counter Strike, for example, you will need to create a server. But as a rule, everything is done quite simply.


This happens quite rarely, but sometimes a game does not allow you to play over the Internet, but allows over a local network. Do not despair, even if it turned out that your friend lives far away from you.

Hamachi allows you to emulate a local connection and thus connect your PC via the Internet. All you need to do is to download the program, register and then create a new connection, give it a name and, if necessary, a password. After that you can easily use this network to play.

As you can see, connecting computers to a local network is a fairly easy process. It will not take you much time and you will be able to connect two PCs and then play with your friends, being both away from them and being in the same room with them.

The ways to create a connection are suitable for all Windows. from XP to “10.
