Connect two computers via a local network. Methods for reliable connection of wires. Connecting wires with PPE caps

Between themselves. I would like to say right away that you can use several methods to perform this operation. In this article I will describe a method using twisted pair. I will also provide one alternative method using wireless network. So, next you will learn how to connect two computers to each other.

Preparation

Surely you have at least once been to an Internet cafe or a computer science classroom at school. And there you observed many separately located computers that could somehow interact with each other. For example, produce combined or correspondence. So, in most cases in such places a built-in local network is used. Interaction is achieved using a special UTP cable (or, as it is popularly called, “twisted pair”). In places like computer clubs, there is also a router. To connect two computers to each other, such a device does not need to be used. Since it is necessary to connect more than two PCs. Also, of course, it is necessary that it be installed in both computers, otherwise the wire will simply have nowhere to insert it. Below we will describe how to connect two computers to each other via a twisted pair cable.

Instructions

First of all, prepare both PCs. Turn them on and, preferably, place them next to each other first (to observe the changes). Now let's get down to the instructions themselves.

Alternative method

Previously, you learned how to use a cable. But now we live in a world of high technology. Therefore, in some cases it is not advisable to use a primitive cable. Therefore, I suggest you try the system wireless communication Wi-Fi. It allows you to achieve the same results as through a cable, only without a physical connection. In this case, you will have to incur additional costs for the purchase of a Wi-Fi router (as well as for receivers, if they are not provided in the equipment). The most difficult thing about this method is setting up the dispenser. There is no point in giving precise instructions for this process, since the setup will depend on the brand of equipment.

Conclusion

The need to connect multiple PCs may vary. For example, to join a local network in order to play games together. Or maybe you want to save on internet costs using one connection. One way or another, this can be done, and very quickly. I hope you understand how to connect two computers to each other.

Although rare, there are situations when you need to connect two computers to each other without using a switch. There are several ways to do this. This is the use of a crossover patch cord, the use of an LPT cable, etc. In this article we will tell you how to use a cross-linked patch cord.

Materials and tools

Crossed patch cord (a cable on the end connectors of which the yellow and green pairs are swapped) and two computers.

Technology

1. Connect both computers with a crossover patch cord. Paste into network port On the first computer, connect one end of the patch cord and the other end of the cable to the network port of the second computer.
2. Make sure that the indicators on the network ports on each computer are lit (assuming that both computers are assembled and connected to power).
3. Congratulations, you have completed the first part. You have physically connected computers. All that remains is to configure each of them programmatically, and the job is done.
4. Go to setting up the network card using the following path: Start - Settings - Control Panel - Network Connections - Connection via local network.
5. Right-click on the “Local Area Connection” icon and select “Properties” from the menu that appears.
6. In the window that opens, select the “Internet Protocol TCP\IP” component and click the “Properties” button.
7. On the “General” tab, check the “Use the following IP address” checkbox. You will immediately be able to enter fields with an IP address and subnet mask.
8. Enter the following address in the “IP addresses” field - 192.168.0.101
9. Enter the following address in the “subnet mask” field - 255.255.255.0
10. Click on the "Ok" button.
11. Click on the “Ok” button again.
12. To set up a workgroup, follow the following path: Start - Settings - Control Panel - System.
13. In the window that appears, select the “Computer name” tab.
14. Click on the "Change" button.
15. In the resulting window, fill in the “Computer name” field: for example, “comp1”.
16. Check the box next to “is a member of the working group.”
17. Enter the workgroup name "workgroup".
18. Click on the "Ok" button.
19. Click on the “Ok” button again. The system will prompt you to restart your computer for the changes to take effect. Reboot.
20. Perform the same steps for the second computer, only specify “comp2” as the computer name. The IP address in this case will look like this: 192.168.0.102, the subnet mask will remain unchanged (255.255.255.0), as well as the workgroup name (“workgroup”).
21. Reboot the second computer.

Now you can be congratulated on successfully setting up and connecting two computers with one patch cord into a small network. Make public directories on both computers and enjoy using them!

A local network or LAN is two or more computers connected to each other directly or through a router (router) and capable of exchanging data. Such networks usually cover a small office or home space and are used to share an Internet connection, as well as for other purposes such as file sharing or online gaming. In this article we will talk about how to build a local network of two computers.

As it becomes clear from the introduction, you can combine two PCs into a local area in two ways - directly, using a cable, and through a router. Both of these options have their pros and cons. Below we will look at them in more detail and learn how to configure the system for data exchange and access to the Internet.

Option 1: Direct connection

With this connection, one of the computers acts as a gateway for connecting to the Internet. This means that it must have at least two network ports. One for global network, and the second for local. However, if the Internet is not required or it “comes” without the use of wires, for example, through a 3G modem, then you can get by with one LAN port.

The connection diagram is simple: the cable is plugged into the corresponding connectors on the motherboard or network card of both machines.

Please note that for our purposes we need a cable (patch cord) that is designed for direct connection of computers. This type is called a “crossover”. However, modern equipment is capable of independently determining pairs for receiving and transmitting data, so a regular patch cord will most likely also work fine. If problems arise, you will have to redo the cable or find the right one in the store, which can be very difficult.

The advantages of this option include ease of connection and minimal equipment requirements. Actually, we only need a patch cord and LAN card, which in most cases is already built into motherboard. The second plus is high data transfer speed, but this depends on the capabilities of the card.

It's a stretch to call the disadvantages such - they reset the settings when reinstalling the system, as well as the inability to access the Internet when the PC, which is the gateway, is turned off.

Settings

After connecting the cable, you need to configure the network on both PCs. First, we need to assign a unique name to each machine in our local area. This is necessary in order to software could find computers.

Now you need to configure shared access to resources on the local network, since by default it is limited. These steps also need to be performed on all machines.

1. Right-click on the connection icon in the notification area and open "Network and Internet settings".

   

2. Let's move on to setting up sharing parameters.

   

3. For a private network (see screenshot), enable discovery, enable file and printer sharing, and let Windows manage connections.

   

4. For the guest network we also enable discovery and sharing.

   

5. For all networks, we disable general access, configure encryption with 128-bit keys, and disable password access.

   

6. Save the settings.

   

In Windows 7 and 8, this block of parameters can be found like this:

1. On the first PC (the one that connects to the Internet), after going to the parameters (see above), click on the menu item "Configuring adapter settings".

   

2. Here we select "LAN connection", right-click on it and go to properties.

   

3. In the list of components we find the protocol IPv4 and, in turn, move on to its properties.

   

4. Switch to manual input and in the field "IP address" enter the following numbers:

   In field "Subnet mask" the required values ​​will be automatically entered. There is no need to change anything here. This completes the setup. Click OK.

   

5. On the second computer, you must set the following IP address in the protocol properties:

   We leave the mask as default, but in the fields for the gateway and DNS server addresses we indicate the IP of the first PC and click OK.

   

   In the "seven" and "eight" you should go to "Network Control Center" from the notification area, and then click on the link "Change adapter settings". Further manipulations are carried out according to the same scenario.

   

The final procedure is to allow shared access to the Internet.

Now on the second machine it will be possible to work not only on the local network, but also on the global one. If you need to exchange data between computers, you will need to perform one more setup, but we will talk about this separately.

Option 2: Connection via router

For such a connection, we will need, in fact, the router itself, a set of cables and, of course, the corresponding ports on the computers. The type of cables for connecting machines to a router can be called “direct”, as opposed to a crossover cable, that is, the cores in such a wire are connected “as is”, directly (see above). Such wires with already mounted connectors can be easily found in retail stores.

The router has several connection ports. One for receiving the Internet and several for connecting computers. It’s easy to distinguish them: LAN connectors (for cars) are grouped by color and numbered, and the port for the incoming signal stands apart and has a corresponding name, usually written on the case. The connection diagram in this case is also quite simple - the cable from the provider or modem is connected to the connector "Internet" or, in some models, "Link" or "ADSL", and computers to ports signed as "LAN" or "Ethernet".

The advantages of this scheme are the ability to organize a wireless network and automatically determine system parameters.

Very often, users on forums look for information about connecting two computers to a local network. A similar question is asked not only to forum participants, but also on sites where the so-called FAQ (question-answer) is implemented. Since connecting computers via a LAN cable also raises questions among blog visitors, I decided to write a detailed instruction article. It should be said that in this publication we will consider connecting two computers to a network with a LAN cable, and wireless Wi-Fi connection We will consider it in one of the following publications.

As you understand, for a local connection of two computers we need a LAN cable crimped in a cross-type manner. It is worth saying that for computers with an Ethernet Auto-MDIX interface (an interface depending on the transmission medium), the type of crimping (direct or cross) does not matter because the network port is configured automatically. This technology must be supported by two devices.

Nothing is perfect, and in practice it happens that network cards with Ethernet Auto-MDIX refuse to work correctly. To avoid such situations, I recommend that you adhere to twisted pair crimping standards and use each type of LAN crimping for its intended purpose. Before connecting two computers to a local network, be sure to make sure that you are using a working and correct type of cable. Details about where the straight and cross type are used and how to crimp a LAN cable without crimpers (crimping tool).

The length of the twisted pair cable for connecting two computers into a local network should not be more than 100 meters. Otherwise, signal attenuation will affect the quality of the network.

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

So, you have connected two computers using one of the methods described above. If you are creating network connection two computers via the RJ-45 connector, then the Ethernet controller indicator light should light/blink green (usually the indicator light is located near the RJ-45 connector). If this does not happen or the indicator lights up on only one computer, then check that the cable is crimped correctly.

Also make sure that the network adapters are turned on, their drivers are installed, and the devices are working properly. But if the indicators on two computers light up or blink, then it follows that the hardware connection is established and the cable has no breaks and is working correctly.

If you use the Windows 7 (Windows XP) operating system, then as a rule, after connecting, the computers begin to “see” each other and work normally. It all depends on the preset parameters. However, if this does not happen, then you need to make some changes to the network connection parameters.

Let's look at a direct connection of two computers via a FireWire or LAN (twisted pair) cable running the Windows XP operating system, and then we'll look at how to combine two computers running Windows 7. It is advisable that the two computers being connected be in the same workgroup.

Connecting two computers to a network running Windows XP.

Go to Start, Control Panel and click on the Network Connections icon. Right-click on "Local Area Connection" and context menu go to “Properties”.

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

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

• IP address: 192.168.1.1
• Subnet mask: 255.255.255.0
• Default gateway: 192.168.1.0 (enter if computers will not see each other)

That is, it is not necessary to enter “Main Gateway,” but if the computers will not see each other, then enter this parameter as well. After that, click “Ok” in all windows.

You need to do the same on another computer, but enter a different IP address. For example, like this:

• IP address: 192.168.1.2
• Subnet mask: 255.255.255.0
• Default gateway: 192.168.1.0 (must be entered if there is no connection)

Now a connection should be established between the computers (if there is no connection between the personal computers, then reboot them). To make sure the settings are correct, go to “Network Connections” and click on the “Local Area Connection” icon. The “Status” window should show “Connected”.

If “Connection is restricted”, check that the parameters are filled in correctly network connection. With connection in the operating room Windows system XP figured it out, now let's look at how to organize a network between two computers in Windows 7.

Connecting two computers into a network running Windows 7.

Actually, in Windows 7 there are no special differences for connecting two computers to a network, but to make it clear to those who use this particular operating system, I will describe the sequence of actions specifically for them.

Go to Start, Control Panel and select Network and Internet. Next, go to “Network and Management Center” shared access" and click on "Change adapter settings". Here we are. Right-click on “Local Area Connection” and go to “Properties”.

Now go to “Internet Protocol Version 4 (TCP/IPv4)” and switch the button to “Use the following IP address.” Next you need to enter your network parameters.

It makes sense to enter a default gateway if there is no connection between computers. For example, like this:

• IP address: 192.168.1.7
• Subnet mask: 255.255.255.0
• Default gateway: 192.168.1.0 (enter if there is no connection)

You can set any other parameters for the IP address, as long as they are in the range from 192.168.1.1 to 192.168.1.254.

On the second computer, you need to enter exactly the same parameters and change the last digit in the IP address. For example, like this:

• IP address: 192.168.1.8
• Subnet mask: 255.255.255.0
• Default gateway: 192.168.1.0 (please enter if there is no connection)

After you set the necessary parameters, do not forget to click the “Ok” button in all windows. If there is no connection, restart your computers. To make sure that everything is working correctly, you need to check the connection between the computers. To do this, on one of the two computers, open command line. Go to Start and enter cmd in the search field labeled “Search programs and files.”

For example, to check communication on a computer with IP parameters 192.168.1.7, enter the command ping 192.168.1.8 and press the Enter key.

A positive result will be the result shown in the image. If sent = 4, received = 4, lost = 0, then everything is configured correctly. The two computers are connected directly.

Now you can exchange files between computers. Bye!

I don't quite understand your question. Why does something have to fly off? Or do you mean that you need to change network settings? For example, to connect to the Internet.

Today, there are many ways to connect wires in a junction box.

Here are the factors that determine the choice of connector:

1. Core material (copper or aluminum).
2. Working conditions (outdoors, in an apartment, in water, in the ground, in the floor, normal conditions).
3. Number of conductors (two, three, four, etc.).
4. Core cross-section (same, different).
5. Core structure (single-wire or multi-wire).

Based on these factors, the most suitable and correct method is selected. First, let's look at the materials that can be used to connect electrical wires in a junction box.

Existing methods

The following connection options are considered the most popular and effective:

• use of terminal blocks;
• installation of spring terminals (wago);
• fixation with PPE (plastic caps);
• crimping with sleeves;
• soldering;
• twist;
• installation of “nuts”;
• use of bolts.

Let's consider the essence, advantages and disadvantages of each method!

Installation of PPE caps

PPE stands for connecting insulating clips. The products are ordinary plastic caps that have a special spring inside that holds the wires.

Most often, such caps are used to connect cores in junction boxes.

Advantages of using these products:

• low cost of PPE;
• the caps are made of non-flammable material, so there will be no twisting at the site;
• quick installation;
• The caps have a wide range of color shades. For example, if the wires do not have a wire, you can use PPE to mark it (using a white, blue and green cap).

Flaws:

• relatively poor quality of insulation and fixation;
• It is impossible to combine aluminum with copper.

Crimping with special sleeves

Stranding and insulation

The old “grandfather’s” method consists of twisting the cores together. The essence of the work is that the conductors are stripped and carefully twisted with pliers, after which the twisted area is insulated.

Advantages:

• simplicity of electrical installation work;
• no material costs.

Flaws:

• poor quality of core fastening;
• The connection of aluminum and copper products is unacceptable.

WITH using existing methods We have figured out the connections of the wires in the box, now we will consider the remaining, important issues of this topic.

What to do if there are several wires?

There are usually no problems when connecting two contacts. But what to do if you need to combine three, four or more at the same time?

• using wago terminal blocks;
• crimping with sleeves;
• soldering;
• twisting using sizes;
• twisting and wrapping with electrical tape.

We discussed in detail the order of connecting the wires for each method above. We strongly recommend that you use the first option, because... it is one of the most modern and effective. At the same time, the cost of the vag is not too high, and the wiring lasts more than 30 years.

What to do if the wires are of different sections?

To connect cores of different cross-sections in the junction box, it is recommended to use the same Vago terminal blocks, or a cheaper option - ordinary terminal blocks. In this case, you need to carefully tighten the wires with a screw or secure them with a flag, and that’s it, the work is finished.

We draw your attention to the fact that if the wires are made of different materials, then it is necessary to use special blocks with paste inside, which will prevent oxidation of the wires. Such pads include products from Wago.

Also, cores of different sections can be secured by soldering.

Combining stranded and single-core wires

Connecting single-core and stranded wires separately has no special features, so you can use any of the methods listed above.

In order to carry out fastening, you must choose one of two options: vago terminals or soldering. It all depends on your preference; we have provided the advantages and disadvantages of each method.

How to carry out work in water and land

During electrical installation work, a situation often occurs when it is necessary to fasten electrical wiring under water or in the ground. Now we will briefly look at the features of each case!

In water (for example, when installing a submersible pump), it is recommended to use the following technology. To begin with, the ends are soldered, after which the soldering area is carefully insulated with hot-melt adhesive, over which it is placed. If everything is done efficiently and conscientiously, the joint will be airtight and safe. Otherwise, the electrical network may fail.

For connection electric wire in the ground (for example, after mechanical damage), it is recommended to use the method provided above (hot glue and heat shrink), but it is better to protect yourself and use the following method. Clamp the ends of the cable using a terminal block, install a sealed junction box, and then carefully fill the box with a special silicone sealant. Please note that the underground route must additionally be placed in a pipe or box to ensure reliable operation!
