How to enable LAN connection. LAN or Ethernet connection - "Connected", but the Internet does not work (red cross). Access to free resources

Good day, dear readers.
If two computers are used nearby, it is logical to make a Windows 7 LAN connection between them. This is convenient for exchanging files, information, for joint games or using the same equipment. This tool provides additional convenience, as there is no need to constantly use portable memory or exchange data via the Internet, although the speed of the latter today allows you to do this quickly. I will try to tell everything I know about this technology.

So, for starters, it’s worth talking a little about what a LAN connection is. It is a connection between two or more computers. This is done via cable or wireless technology. As mentioned at the beginning, technology allows the exchange of information, and generally helps to speed up the workflow.

Creation( )

We will not dwell on which components are necessary for physical communication. Before directly establishing a connection, you must specify a single workgroup on all devices. To do this, we do a few simple steps:

As mentioned at first, the value must be the same on all devices that will be in the same bundle. In this case, the line " Full name» each equipment is unique.

After that you need to go to Network Control Center". This can be done via Control Panel” or find the connection icon in the tray, and then right-click on it.


increase

In the left part of the window we find the item "". Now we need to enable network discovery and configuration everywhere in automatic mode. In addition, be sure to open public access.


increase

Then we go to All networks". Finding the last point Sharing with password protection where we need to turn it off.
In addition, you need to enable the discovery of individual folders on the computers you want.

As a result, directories from different users should appear in the network environment.

If this does not happen, go to the main menu " Network Control Center” and press “”. Then we do everything according to the prompts.


increase

No icon next to the clock( )

Don't worry right away. Perhaps the corresponding function was simply disabled for some reason.

So, if you have lost the icon near the clock, do the following:

Network not working( )

Every user who has been interacting with other devices in this way for a long time, at least once in his life, has encountered a problem when the connection simply disappears. This can happen for several reasons. The most common are problems with network equipment. In most cases, a simple reboot helps.

Sometimes it is necessary to re-register all the parameters. How to set up a switch or router? To resolve this issue, it is better to contact a specialist, as it often depends on the specifics of use.

Installing a network printer( )

Separately, it should be said about connecting the printer over the network. Believe me, when more than one computer is used in the room, sooner or later it will be necessary to print from each of them. Do not constantly transfer documents from one to another. To do this, you need to make some movements:

How to turn on the device we need on other PCs or laptops? You just need to install it. For this:

At first glance, setting up a network seems like a complicated process. But actually it is not. Of course, there are connections that require special knowledge from a specialist. In fact, if you are not sure of your actions, it is better to contact the master.

I hope the information above has helped you. Subscribe to updates, and you will be the first to know the most interesting data regarding the operation of Windows and computer technology in general.

Local network with Internet access. If you have several computers at home and all your household members are constantly working on them, and only one of them has Internet access, then you have probably wondered more than once: - How to connect all these computers to high-speed ADSL Internet via one modem?

That's what we'll talk about now. Moreover, not all computers are necessarily desktop. This can be done with laptops too. I will describe all the settings for Windows XP. Although the same can be done for other systems. The difference is only in access to the settings of the network card. In all operating systems, network card settings are hidden in different ways.

The only difference is in the way to them, because. different systems have different control panels. As good and fancy as the new operating systems are (Vista and Windows 7), I prefer Windows XP. Its settings (especially for the local network) are the most flexible and simple.

I have three computers at home, and everyone is constantly busy. And for a long time Internet access was only on one computer, which is very inconvenient. But then the moment came when we realized that it was time to do something. We gathered a small home council and decided to create our own small local network with general Internet access.

What do we need to build a local network with Internet access

Bought a switch for five ports,

and three network cables: one - 3 meters and 2 to 10 meters.

network cards in all three computers built into the motherboard, so we bought only one - to connect the modem.

We already have a modem.

In general, everything cost "little blood" - a little more than 700 rubles.

Connecting equipment for a local network

WITH INTERNET ACCESS

  • Installed a new network card in PCI-slot computer with direct Internet access. This computer will be our Server. The system immediately detected it and installed the necessary driver itself (if your system could not install the driver, then install it yourself from the disk that is sold with the network card).
  • We connected a modem to this network card and.
  • We will connect a cable to the second network card of the same computer, which will be connected to the switch at the second end.
  • Connected network cables to the network cards of each computer.

  • The second ends of the cables were connected to the switch and connected to the mains. The LEDs blinked and on the monitor screens, messages appeared that the network cable was connected.

LAN setup

WITH INTERNET ACCESS

Then we started setting up the local network.

  • Started from Server settings with direct Internet access. To do this, choose - Start — Setting — Control Panel — Network connections .
  • First, we renamed the network card to connect the network, so as not to get confused in the future. They named her solidly - " LAN" (local computing network).
  • We now have an icon called " LAN” is the network card to which we have the LAN cable connected. Let's look at the settings of our network card for the local network. To do this, right-click on the " LANProperties ».

  • The window " LAN - properties ". If you named your network card differently, then you will have a different name, only the word Properties will not change. Roles, this does not play any, so you can not get hung up on this.

  • In this window, on the tab " General» double-click on the entry « Internet protocol (TCP/ IP) "or select this entry and click the button below" Properties ».
  • The following window will open TCP/ IP) ».

  • In it, we make it active (set a point) opposite the entry “ Use the followingIP-the address: ».
  • Assign to our computer, which will connect to the Internet directly via modem IP-address: 192.168.0.1 (if you have never set up a network, then it’s better to write the same as ours). The last digit must be 1 . The server must be the first on the network.
  • Subnet mask: 255.255.255.0 (dots are not required anywhere). Nothing else needs to be written anywhere. Save everything (click the button " OK «).
  • Put the checkmarks at the bottom on « When connected, display the icon in the notification area ” and “Notify me when there is limited or no connection ”, so that you can immediately see if the cable has come off or for some other reason there is no network. And once again we save everything.
  • We have configured the entire network card of the first computer named "Server". Now let's move on to setting up the network itself.
  • Select the icon " LAN ».

  • And click on the left in Network tasks on the icon of the house " Set up a home or small office network ».

  • The window " Network Setup Wizard ". Click on the button " Further ».

  • In the next window, press the button again Further ».

  • In the next window, put a dot on the entry " Other"and press the button" Further ».

  • In this window, set the point to " This computer belongs to a network that does not have an Internet connection ” (this makes it easier to set up the network).
  • And again press the button Further". The next network settings window will open, where we will be asked to give a name and description.

You don't have to write a description, but the name should be clear to you. Better change it at this step. For everything to work without problems, all names must be written in English letters, and it does not matter in large or small.

At first we called the computer STELLA so it writes the current name STELLA, and now we will rename it to SERVER. And again press the button Further". In the next window, you must specify the workgroup.

You can leave the name of the working group as it is, or you can change it to the one you like. It also doesn't affect anything. We press the button " Further «.

This page is best left as is.

On the next page, you will see all the data that you entered to set up your network. If something does not suit you, you can return by clicking the button " Back and change what you need. If everything suits, then press the button " Further ».

In this window, it is better to set the point to " Just complete the wizard… ».

Next, press the button " Ready” and the system will prompt you to reboot. Follow this advice. In the same way, we configured the network cards on the other two computers. The only difference is only in a different name, and the name of the group must be the same for everyone (i.e. the same).

On another computer, as you can see, the name of the icon has not been changed, since there are no other icons, and you can’t confuse it with anything. There is only one network card.

AT " Internet protocol (TCP/ IP) »For the second computer, write:

IP -address: 192.168.0.2

Default Gateway: 198.162.0.1

PreferredDNS -server: 192.168.0.1

AlternativeDNS -server: we don't write anything

AT " Internet protocol (TCP/ IP) "For the third computer, we write:

IP -address: 198.162.0.3

Subnet mask: 255.255.255.0

Default Gateway: 198.162.0.1

PreferredDNS -server: 192.168.0.1

AlternativeDNS -server: do not write anything

Everything is the same as on the second, only IP-addresses last digit 3 .

Our network is set up. Now we configure the network card to which the modem is connected (if you already have a modem connected and the Internet is configured, then you can skip this part of the article).

We go again to the first computer, which was called " Server". We go to - Start – Control Panel – Network connections . Right click on the network card icon Internet and select " Properties ».

The window " Internet properties ". In it, on the tab " General» select in the small window « Components used by this connection: » entry « Internet protocol (TCP/ IP) " and open it either by double-clicking or by pressing the " Properties ».

In the new window that opens Properties: Internet Protocol (TCP/ IP) » set a point on the record « Use the followingIP-the address: " and write:

IP-the address: 192.168.1.26

Subnet mask: 255.255.255.0

Default gateway: 192.168.1.1

(These figures may be different for you. You can find them by calling the technical support phone from your Internet provider).

And press the button " OK ».

We fall again into the window " Internet properties ". Go to the tab " Additionally ».

Put a check mark in it Allow other network users to use this computer's Internet connection. And uncheck "Allow other network users to manage Internet connection sharing"". We press the button " OK and restart all computers. That's all. We now have a network with all computers connected to the Internet.

  • Main condition: The “server” must be turned on and connected to the Internet, even if no one is working on it yet, otherwise other computers will not be able to access the Internet.

On other computers (Clients) you only need to launch your browser (Opera or whatever you have installed).

Here is the connection diagram of our computers:

It is imperative to install an antivirus program on all computers, especially since it can be updated regularly for you. Enjoy the advantage of a local network.

Connecting two computers to the Internet

The settings are no different from the connection that we reviewed above. The only difference is the absence of a switch, because we simply connect one computer to another with a single network cable.

By the way, from my experience I can say that you can take the same cable as for the local network, and not twisted pair. For two computers it doesn't matter. But when you connect a twisted pair to the switch, your network will not work.

Here are the questions we looked at:

  • XP LAN Setup,
  • connecting two computers to the Internet,
  • Internet Connection Sharing,
  • local area network with public Internet access.

Soon I will tell you , And How .

Video How to remove the password for access to the network, folders and printers

Good day!

Eh, if in the 90s of the last century a computer was a luxury, now many people have not one, but several computers / laptops at home. If you connect computers to a local network (in which there will even be only 2 devices), you can get undeniable advantages:

  • the ability to open files located on another PC, work with them, etc. Now you do not need to run back and forth with a flash drive or disk;
  • the ability to make a network printer (scanner, CD / DVD drive, etc.), and use it from all PCs in the local network;
  • the ability to play network games (this is a separate and most interesting opportunity, which can be talked about for a long time).

In this article, I wanted to consider the issue of building a home local network (and setting it up), which will be useful to all novice users. I will follow the path of step-by-step analysis, I will start with the question of connecting one PC to another, then I will consider setting up Windows, and how, in fact, to share (make available to the local network) folders, printers, etc. So...

When creating a home local network, most often, two options are used:

  1. connect two computers (PC to laptop, PC to PC, etc.) using a cable (it is often called twisted pair);
  2. get a special "box" called a Wi-Fi router. A PC is connected to the router using a network cable, and laptops, phones, tablets, etc. devices get Internet access via Wi-Fi (the most popular option today).

Option number 1 - connecting 2 PCs using twisted pair

Pros: simplicity and cheapness (you need 2 things: a network card, and a network cable); providing a sufficiently high speed that not every router is able to issue, a smaller number of radio waves in the room.

Cons: extra wires create confusion, get in the way; after reinstalling Windows OS - network setup is required again; for Internet access to be on the second PC (2), the first PC (1) must be enabled.

What is needed: that each PC has a network card, a network cable. If you plan to connect more than 2 PCs to a local network (or so that one PC is connected to the Internet and is on the local network at the same time), one of the PCs must have 2-3 or more network cards.

In general, if both PCs have network cards, and you have a network cable (also called an Ethernet cable), then connecting them with it is not difficult. I don't think there is much to consider here.

Note: Please note that network cards usually start to turn green (yellow) LED when you connect a cable to it.

Another important point!

Network cables for sale are different: and not only in color and length. The fact is that there are cables for connecting a computer to a computer, and there are those that are used to connect a PC to a router.

For our task needed crossed network cable (or cable pressed in a cross way- here who calls it).

In a crossover cable - on the end connectors, the yellow and green pairs are reversed; in the standard (for connecting a PC to a router) - the colors of the contacts are the same.

In general, if two PCs are turned on, working, you connected them with a cable (the LEDs on the network cards blinked), the network icon next to the clock stopped displaying a red cross - that means the PC has found the network and is waiting for it to be configured. This is what we will do in the second section of this article.

Option number 2 - connecting 2-3 or more PCs using a router

Pros: most devices: phones, tablets, laptops, etc. will have access to a Wi-Fi network; fewer wires "underfoot", after reinstalling Windows - the Internet will work.

Cons: purchase of a router (after all, some models are far from cheap); "complicated" device setup; router radio waves ., lower ping and freezes (if the router can not cope with the load).

What you need: a router (it usually comes with a network cable to connect one PC to it).

With the connection of the router, as a rule, there are also no big problems: the cable coming from the Internet provider is connected to the special. router connector (it is often called "Internet"), and local PCs are connected to other connectors ("Lan-ports"). Those. the router becomes an intermediary (an example diagram is shown in the screenshot below. By the way, in this diagram there may not be a modem on the right, it all depends on your Internet connection) .

By the way, pay attention to the LEDs on the router case: when you connect the Internet cable from the provider, from the local PC, they should light up and blink. In general, setting up a Wi-Fi router is a separate big topic, besides, for each router, the instructions will be slightly different. Therefore, it is hardly possible to give universal recommendations in one single article ...

By the way, when connecting through a router, the local network is usually configured automatically (that is, all computers connected via a network cable should already be on the local network, there will be a couple of small touches (about them below)). The main task after that is to set up a Wi-Fi connection and access to the Internet. But since this article is about the local network, I do not focus on this ...

LAN setup (Windows 7, 8, 10)

In this subsection of the article, I will give universal instructions, regardless of how your local network is organized: connected via a network cable, or using a router. Where the settings will relate to a specific option - there will be notes.

Note: all settings are relevant for Windows 7, 8, 8.1, 10.

Computer name and workgroup

Allegory: each person has his own name, surname, patronymic, date of birth, city, etc. - No two people are the same. It is the same in the network - there should not be computers with the same name ...

The first thing to do when setting up a local network is to check and configure workgroup name and computer name. Moreover, you need to do this on each computer in the local network!

To find out the computer name, open the Windows Control Panel at: Control Panel\System and Security\System (screen below). Next, make sure the following:

  1. PC name and slave. the group must be in Latin;
  2. each PC / laptop in the local network should have its own unique name(for example: PC1, PC2, PC3);
  3. Every PC/Laptop should have same working group (for example: WORKGROUP).

To change the name and working group - click the "Change settings" button.

Change workgroup and PC name

In general, when you bring all the names in accordance with the requirements above, you can proceed to the next step of the setup.

Turn on printer and folder sharing

Relevant for connecting through a router, and directly ...

This innovation appeared in Windows 7, supposedly provides greater security for the OS (in my opinion, it only creates the need for additional local network settings). The bottom line is that, by default, Windows blocks and does not allow access to open and share folders, a printer, etc., until the security policy is "softened".

To remove this lock and enable sharing, you need to:


Setting up IP addresses, DNS, masks, gateways

For a network organized using a router

In general, for PCs connected to a local network using a router, usually nothing needs to be configured (everything works by default). If something is wrong, just in case, I recommend that you go in and check the connection properties.

To do this, you first need to open "network connections" . This is done simply:

  1. first open the window "Run"- combination of buttons Win+R;
  2. then enter the command ncpa.cpl and press Enter(works in all versions of Windows 7, 8, 10).

How to open network connections // ncpa.cpl

Local Area Connection Properties

To connect PC to PC via network cable

PC 1

By PC 1, I mean a computer that has two network cards: one of them is connected to the ISP's Internet cable, and the second is a local network cable that goes to PC 2.

Note: although, the Internet cable from the provider does not have to be. If it is not there, choose PC 1 and PC 2 - arbitrarily ...

And so, we open network LAN connection properties(how this is done - see a little higher in the article).

  1. IP address: 192.168.0.1;
  2. subnet mask: 255.255.255.0 (see screenshot below);
  3. save your settings.

AT properties of IP version 4 (TCP/IPv4) second PC, you need to set the following parameters:

  1. IP address: 192.168.0.2,
  2. subnet mask: 255.255.255.0;
  3. default gateway: 192.168.0.1;
  4. preferred DNS server: 192.168.0.1 (see screenshot below);
  5. save your settings.

Actually, the local network setup itself is finished. Now you can proceed to the most interesting part - sharing and using the shared resources of the local network. Exactly what we were going for...

Sharing Internet access on a second PC

Relevant for PCs connected directly by LAN cable...

You need to configure PC 1 (i.e. the one to which we have the provider's Internet cable connected).

First we open network connections : press combination Win+R, enter ncpa.cpl, Further Enter .

How to open network connections //ncpa.cpl

Next, open the tab "Access", and check the box next to "Allow other network users to use this computer's Internet connection" . Save your settings.

Allow other users to access the internet

If everything is done correctly, the Internet will be on both computers.

Note: of course, for the Internet to be on PC 2 - PC 1 must be turned on! This, by the way, is one of the inconveniences of such a local network, when connected through a router - the Internet will be regardless of which PC is on / off.

Sharing folders/files for public access

3) Set the resolution: read or read and write.

Note:

  • allowed to read: users can only copy your files to themselves (neither delete nor change - they can't!);
  • read and write allowed: LAN users will have full control over files in folders: they can delete all files, change any of them, etc. In general, I would not recommend giving such access to important and large folders (to transfer files, it is better to have a separate folder, to which you give full access).

5) After a few seconds, Windows will report that the folder has been shared. So everything went well.

6) To access the folder:

  1. open the explorer;
  2. then open the "Network" tab (on the left, at the bottom of the window);
  3. open computer name, on which the folder was shared. As you can see in the screenshot below, it is shared, you can go into it and start copying (reading) any files.

Printer sharing (shared network printer)

1) The first thing to do is open the control panel: control panel/hardware and sound/devices and printers.

3) Then open the tab "Access" and check the box "Sharing this printer" . Save the settings (see screenshot below). Actually, now the printer is shared and it can be used by other PCs / laptops / tablets and other devices on the local network.

How to share a printer

4) To connect a network printer, open conductor, select computer name , on which the printer is shared. Next you should see it: click on it right mouse button and select the option from the menu connections .

How to connect a network printer

5) Then you can open any document, press Ctrl+P (File/Print), and try to print a friend page.

Note: By default, Windows typically lists a different printer (not the one you have connected over the network). Do not forget when printing - change it.

Regarding the local network printer - I recommend that you read my detailed article on this topic. It covers some of the points in more detail. Link below.

"Creating" a network printer -

I am finishing the article on this. Good luck and fast setup.

Today you will not surprise anyone with a computer in the house. And if you have accumulated as many as two iron pets, then there is a natural desire to combine them together. We will deal with the creation of such a structure, proudly called a "computer network", in this article.


Technical cases

So, you have 2 computers. First of all, you need to check if they have special devices that will allow them to communicate with each other over the network. These devices are called network cards. You may also come across the names "network adapter", "network card", "Ethernet adapter".
The socket in the network card is called the LAN port (from the English Local Area Network - local area network). It is also often referred to as a "LAN port" (short for "Local Area Network") or an "Ethernet port".
Where to look for a network card? For a typical computer, the LAN port is located on the back of the system unit.

For laptops, the network card port is usually located on the side - on the right or left.

In 99.9% of cases, both of your computers will have a network card. If, nevertheless, it is not there, you will have to take the computer to a service and order a service to install a network adapter in it.
Now it's the turn of the cable over which your computers will send signals to each other (these signals are called packages). To connect computers to a network, you need not just any cable, but a special Ethernet cable called " twisted pair of the fifth category».

Where to get twisted pair?

Naturally, in any computer store. But, before you go there, measure the distance between your computers. Please note that a twisted pair cable cannot be strongly bent, twisted, nailed, or violated in any other way. This can damage the communication of your PCs with each other - packets will be distorted or lost, which is completely useless for a future computer network.

So arm yourself with a measuring tape and measure the distance between computers, taking into account all corners, doorways and walls. Add to the resulting value 2-3 meters in reserve. So you will get the length of the twisted pair cable, which you need to buy in the store.

But that's not all. You can't just plug the cable into the LAN port. At each end of the cable, you also need to screw special sockets, called connectors in the computer world. RJ-45(erji 45). They are very similar to telephones, only larger in size.

To connect two computers, you need two connectors - one on each side of the twisted pair. Connectors are also sold in computer stores.

The process of attaching a cable to a connector is called crimping. Expression " crimp twisted pair" means literally: expose the ends of the cable, insert them in the right order into the connector and clamp them well with a special tool. This tool is called crimping Tools or a crimper and looks like this:

How to crimp twisted pair?

You can do this again in a computer store. When you buy twisted pair and connectors, just ask the seller to crimp the cable to connect TWO computers to the network. The word "TWO" is the key here, because to connect three or more computers you need completely different equipment and the cable is crimped in a slightly different way.

Having crimped a twisted pair cable by the store, you will spend money only on a cable, connectors and a crimping service. But suppose that the sellers do not know how to crimp the cable. Then you will have to do it yourself. To do this, you will need to buy a twisted pair cable of the required length + 1 meter for crimping experiments, 2 connectors (preferably 4-6 just in case) and a crimping tool. Costs will increase slightly, but you will learn how to crimp a twisted pair. By the way, you can not buy a crimping tool, but borrow it from a computer scientist you know, if you have one.
So, in front of you is a cable, connectors and a crimping tool. Let's proceed to the twisted pair crimping operation.

1. Remove the insulation from the cable about 2 cm from the edge. You will see 4 pairs of twisted colored wires. Their insulation should not be touched.
2. Carefully unwind these colored wires, separate them and place them evenly in the following sequence, as shown in the picture below (on the left is one end of the cable, on the right is the other end). This scheme is called crossover and is only used to connect TWO computers to each other.

3. Cut off the ends of the cable so that a little more than 1 centimeter remains, and insert them into the connectors. The order of the wiring should be as shown in the figure below. In this case, the connectors must be turned with the flat part towards you. The wires should fit snugly into the connector and rest against its end.

4. Now carefully take the connector with the cable and insert it into the larger connector of the crimping tool. Gently, but with force, we press on the handle and ... one end of the twisted pair is crimped. We do the same with the other end of the cable.
If it doesn't work the first time, don't worry. You have another 1 meter of cable and a few spare connectors for experiments.
And finally, the twisted pair is ready.

Now you can physically connect the computers to each other. Insert one end of the cable, or rather the connector on it, into the LAN port of the first computer until you hear a click. Do not press hard, you need to insert gently and without much pressure!
Plug the connector on the other end of the cable into the LAN port of the second computer. Also gently and gently until you hear a click. That's all, physically the computers are already connected to the network. This completes the technical part of the work. Let's move on to setting up operating systems.

Program affairs

For computers to communicate with each other, they must know about each other. Sounds abstract, but it's true. If you just connected two PCs with a cable, the signals they send out won't go anywhere. And all because they do not know where to go, to whom they are intended, in other words, they do not know the destination address and the names of the recipients.
As in real life, in order for information from one computer (let's call it PC1) to safely reach another computer (let's call it PC2), it must know its address and name. Now we will deal with the assignment of names and addresses to our computers.


Assign a name to a computer running Windows XP:

1.On PC1, right-click the My Computer icon on the desktop and select Properties.

2. In the window that opens, select the "Computer name" tab and click the "Change ..." button.

3.Enter the computer name in English - PC1 and the workgroup name - WORKGROUP. The workgroup name may already be specified (by default it is the same for all Windows computers). In this case, just check that it is WORKGROUP.

4.Click the "OK" button in this and the next window. Then restart your computer for the changes to take effect.

Assign a name to a computer running Windows Vista:

1. On PC1, open the "Start" menu, right-click on "Computer" and select "Properties".

2.Find the "Computer name, domain name, and workgroup settings" section and click "Change settings".

3. In the window that opens, click the "Change ..." button.

4.Enter the computer name in English - PC1, and the workgroup name - WORKGROUP. The workgroup name may already be specified (by default it is the same for all Windows computers). In this case, just check that it is WORKGROUP.

5.Click the "OK" button in this and the next window. Close the Control Panel window and restart your computer for the changes to take effect.
Do the same with the second computer (PC2), only give it the name PC2. The working group on both computers must be the same - WORKGROUP. At the end of the setup, the second computer also needs to be restarted.

We figured out the names. But this is not enough! Now you need to assign a unique address to each computer. But first, a little theory.
The addresses of computers on networks consist exclusively of numbers and are called IP addresses(pronounced "IP", short for Internet Protocol). Moreover, the full address of the computer consists of four blocks of numbers separated by dots: block1.block2.block3.block4

The point after the fourth block is not put! Each block can contain one, two or three digits from 0 to 255. An example of a computer address is 194.65.43.112 or 83.123.43.7
It is so supposed that in local computer networks, to which your home network just belongs, the first two blocks should contain the numbers 192.168, and the next two blocks any from 0 to 255. At the same time, 255 cannot be used at all, and 0 can only be used in the third block. Thus, the address of a computer on a home network can be 192.168.0.1 or 192.168.1.1 or 192.168.1.5 or 192.168.0.10, as well as 192.168.4.56, 192.168.43.112, etc.

There are many such combinations, but only those computers that have the same numbers in the third block can communicate with each other. In our example, these are 192.168.0.1 and 192.168.0.10, as well as 192.168.1.1 and 192.168.1.5. But if the computer 192.168.1.5 wants to send information to the computer with the address 192.168.0.10, then it will fail.
Another important point: there cannot be two or more computers with the same addresses on the same network. Those. if you assigned the address 192.168.1.1 to some PC, you can cross it off the list of free addresses. It is now the property of this PC and cannot be owned by any other computer.

This concludes the theoretical part about computer addresses and move on to practice. Let's assign our PC1 address 192.168.0.100, and PC2 address 192.168.0.6


Assigning an address to a computer running Windows XP:

1. On PC1, click "Start" - "Settings" and double-click "Network Connections".

2.Right click "Local Area Connection" and click "Properties".

3. In the window that opens, select "Internet Protocol (TCP/IP)" and click the "Properties" button.

4.Check "Use the following IP address". In the "IP address" field, enter the address of your computer - 192.168.0.100. Click on the "Subnet mask" field - the value corresponding to the computer address will appear there.

5.Click "OK" in this window and "Close" in the next one. Wait a few seconds for the settings to take effect. Close the Network Connections window.
Thus, you have assigned an address to one computer running Windows XP - PC1. Now sit down at another computer (PC2) and do the same, but instead of 192.168.0.100, assign it the address 192.168.0.6

Assigning an address to a computer running Windows Vista:

1. On PC1, select "Start" - "Control Panel".

2. In the list, select the "Network and Sharing Center" section. In the window that opens, click "Manage Network Connections".

3.Right click on "Local Area Connection" and select "Properties".

4.Select the Internet Protocol Version 4 (TCP/IPv4) item and click the Properties button.

5. Check the box "Use the following IP address" and enter the address of your computer in the "IP address" field - 192.168.0.100
Click on the "Subnet mask" field - the value corresponding to the computer address will appear there.

6.Click the "OK" button in this and the next window. Wait a couple of seconds for the settings to take effect and close the Network Connections and Control Panel window.
Thus, you have assigned an address to one computer running Windows Vista - PC1. Now sit down at another computer (PC2) and do the same, but instead of 192.168.0.100, assign it the address 192.168.0.6

Having finished assigning addresses, proceed to test the connection on your home network.


Network connectivity test with Windows XP:

2.The Windows command interpreter will open. Here you can type various commands, all commands are entered only in English. So far, we are interested in the only command - the command to check communication with another computer. It is called ping (ping). Now we will ping (from "ping", meaning "ping to ...") PC1 with the address 192.168.0.100
Type in the command interpreter ping 192.168.0.100 (in human language, this means "ping the computer with the address 192.168.0.100") and press Enter on the keyboard. The process has begun, we see how PC2 sends packets, and PC1 responds to them.

Fine! There is a connection!


Network connectivity test with Windows Vista:

1.On PC2, open the Start menu and select Run. In the field, enter cmd (in English) and click OK.

2.The Windows command interpreter will open. Type in the shell ping 192.168.0.100 and press Enter on the keyboard. There is a connection: PC2 sends packets, and PC1 responds to them.

Response received from PC1! There is a connection!
You can now sit down at PC1 and ping PC2. Also open a command interpreter and use the ping command, but here the computer address will already be 192.168.0.6. Those. in the shell you will need to type ping 192.168.0.6

That's all. There is a connection, computers send and receive packets from each other. Congratulations on the successful networking of two computers!

In the Windows operating system, you can share a folder on your local home network to exchange data between computers using shared folders. This is a very convenient and fast way to transfer files on a computer-to-computer basis, without using external media (flash drives, external hard drives, memory cards, etc.).

In this article I will talk about creating a local network using the Windows 10 operating system as an example. Creating and configuring a local network in Windows 8 and Windows 7 is done in a similar way, this instruction is universal.

The article discusses the following option for using shared folders on a local network: several computers are connected to the router, connected via cable and a wireless Wi-Fi network, united in a home network. A shared folder is created on each computer, and all computers included in this local network have access to shared folders.

Windows 10, Windows 8, Windows 7 operating systems (different operating systems, or the same operating system) connected to the router via Wi-Fi or cable can be installed on computers connected to a home local network.

Creating and configuring a local network takes place in four stages:

  • the first stage is checking the workgroup name and network card settings
  • second stage - creating and configuring local network settings
  • the third stage is the connection of the shared access to the folder in the local network
  • fourth stage - data exchange over the local network

First you need to check the workgroup settings and network card settings, and then create a Windows local network.

Checking Network Card and Workgroup Settings

On the Desktop, right-click on the “This PC” icon (“My Computer”, “Computer”), select “Properties” from the context menu. In the "System" window, click on "Advanced system settings".

In the System Properties window that opens, open the Computer Name tab. Here you will see the workgroup name. By default, in Windows 10, a workgroup is named "WORKGROUP".

On all computers connected to this local network, the workgroup name must be the same. If the computers connected to the network have different workgroup names, change the names to the same name for the workgroup.

To do this, click on the "Change ..." button, in the "Change computer or domain name" window, give a different name for the workgroup (write the new name in capital letters, preferably in English).

Now check your network card settings. To do this, in the notification area, right-click on the network icon (Internet access). Click on "Network and Sharing Center". In the "Network and Sharing Center" window, click on the "Change adapter settings" link.

In the Network Connections window, select your network card, Ethernet, or Wi-Fi, depending on how your computer is connected to the Internet. Next, right-click on the network card, in the context menu, click on "Properties".

In the network card properties window, in the "Network" tab, select the "IP version 4 (TCP / IPv4)" component, and then click on the "Properties" button.

In the Internet protocol properties window that opens, in the "General" tab, check the parameters of the IP address and DNS service. In most cases, these parameters are assigned automatically. If these parameters are inserted manually, check the appropriate addresses with your Internet provider (the IP address on the computers connected to the network must be different).

After completing the verification of the parameters, you can go directly to creating a local network in Windows.

Creating a local network

The first step is to configure the LAN settings in Windows. Enter the "Network and Sharing Center", click on the item "Change advanced sharing settings".

In the "Advanced Sharing Options" window, you can change the sharing settings for various network profiles. The Windows operating system for each network used creates a separate network profile with its own special settings.

There are three network profiles available:

  • Private
  • Guest or public
  • All networks

In the private network profile, in the "Network discovery" option, select the "Turn on network discovery" option.

In the "File and Printer Sharing" option, activate the "Turn on file and printer sharing" option.

In the HomeGroup Connection option, select Let Windows manage HomeGroup connections (recommended).

After that, open the network profile "All Networks". In the Public Folder Sharing option, select Turn on sharing so network users can read and write files in shared folders.

In the "File Sharing Connection" option, select the "Use 128-bit encryption to secure connections for sharing (recommended)" setting.

In the "Password protected sharing" option, activate the "Turn off password protected sharing" option.

After completing the settings, click on the "Save Changes" button.

Repeat all these steps on all computers that you plan to connect to your home LAN:

  • check workgroup name (name must be the same)
  • check network card settings
  • in sharing options turn on network discovery, turn on file and printer sharing, turn off password protected sharing

How to enable folder sharing

In this case, I created a folder and named "Public". Right-click on this folder, in the folder properties window, open the "Access" tab.

Then click on the "Advanced Settings" button.

In the "Advanced sharing settings" window, activate the "Share this folder" item, and then click on the "Permissions" button.

Select permissions to use shared folder data from another computer. There is a choice of three options:

  • Full access
  • Change
  • Reading

To save the settings, click the "OK" button.

Go back to the folder properties, open the "Security" tab, and then click on the "Edit ..." button.

In the window that opens, enter the name "All" (without quotes) in the "Enter the names of the objects to select" field, and then click the "OK" button.

In the folder properties window, in the "Security" tab, configure the permissions that you previously selected for the shared folder.

To change the permission for the "Everyone" group, click on the "Advanced" button. In the "Advanced security settings for the shared folder" window, select the "Everyone" group, and then click on the "Edit" button to change permissions.

The LAN setup in Windows is now complete. In some cases, you may need to restart your computer for all changes to take effect.

Login to the local home network

Open File Explorer, in the "Network" section you will see all available computers connected to the local home network. To log in to another computer, click on the computer name, and then click on the shared folder name to access the files and folders in the shared folder.

The local network in Windows 10 is created and configured.

Troubleshooting some network issues

Sometimes, after setting up the network, there are problems with accessing folders on the local network. One of the possible problems may be an incorrectly selected network profile. I have experienced this myself on my computer. After reinstalling the system, I created and configured a local network, but my computer did not see two laptops connected to this network. From a laptop, I could easily go to the shared folder of my computer, but the computer did not see them at all.

I checked all the local network settings several times, and only then noticed that my computer was running a public network, and not a private (home) network, like on laptops. How can such a problem be solved?

Enter the "Network and Sharing Center", click on "Troubleshoot". Select the "Shared Folders" section, run diagnostics and troubleshooting. At the very end, the application will offer to set up the network as private. Apply this fix, and then restart your computer. After performing this operation, my computer was able to access shared folders on laptops on the local network.

Often problems arise due to incorrect network settings. Windows 10 has an option to reset network settings to default. Enter "Settings", "Network and Internet", in the "Change network settings" section, click on "Reset network" to apply the default network settings.

There may be other problems, look for their solution on the Internet.

Article Conclusions

In Windows, you can create a local private (home) network between computers to organize data exchange using shared folders, access the printer. Different or identical operating systems (Windows 10, Windows 8, Windows 7) can be installed on computers on the same network.
