Windows 7 local network twisted pair. Do-it-yourself local network: General rules for building a home network and its main components
In the previous article we looked at it using the simplest unmanaged switch. This scheme received the sonorous name “star” in the scientific literature and is in a universal way organization of any peer-to-peer local network with a small number of subscribers.
However, to acquire optional equipment to create a local network between two computers is at least impractical: this will not only become an additional expense line, but will also “weigh down” our circuit with extra wires and equipment.
Therefore, this lesson is devoted to how to create a local network between two computers without resorting to the use of any additional devices.
How to connect two computers over a local network?
To begin with, we note that there are two types of home networks: wireless local area networks and wireless networks. cable connection functional units.
A wireless (virtual) connection is made using a router and does not depend on the finite number of PCs connected to the network. This is an important and quite extensive topic, so we will devote a separate lesson to creating a virtual local network.
Here we’ll talk about how to connect 2 computers via network cable– a simple and stable way to create drugs.
The advantages of such a network include reliability, general accessibility and simplicity of design: repair and configuration of a computer-to-computer network is carried out using improvised means.
At the same time, the only drawback of the system is its low mobility: the network cable reliably “connects” the PC, and it will no longer be possible to freely walk around the house with a laptop connected to the network.
So, to create a home network between two computers, we need:
- - network cable – simple twisted pair for four pairs of copper wires with a cross section of 0.5 mm. By the way, twisted pair got its name due to the special design of the cable: each pair of wires here is twisted together;
- - RJ-45 connectors;
- - crimping.
Buy twisted pair You can go to any computer store and ask the seller to crimp it on both sides with RJ-45 connectors.
If you are refused this service (for which sellers have every right), you will have to additionally buy a “crimp” (which is several times more expensive than the cable itself) and at least two RJ-45 connectors.
(For more information about the correct cable pinout, see the article “how to crimp a network cable”)
The finished crimped cable should be connected to the network card of the first and second computers.
U desktop computers connector network card located on the back wall system unit, and for laptops - on the side or rear panel of the PC.
How to set up a local network between two computers?
After connecting the cable, we register the settings of our local network on each computer.
To do this, go to the settings of the PC’s network card and indicate the IP address there of this device. The standard IP addresses are: 192.168.1. and 192.168.0, where the last digit is selected from a specified range and must be unique for each connected PC.
Then you should check the functionality of the network (similar to creating a simple home network) and install necessary for the user software(for example, programs for transferring files, exchanging text and audio messages etc.)
The local network ready! Now you can freely play online with friends, transfer any information and, in fact, do what you created a local network for two computers for.
This article will talk about and how to properly configure local windows network 7 if it is missing or disappears.
First of all, you should try: Download and install new drivers for the network card; Install native drivers from the disk instead of Windows specific ones.
Disable Internet Protocol Version 6 (TCP/IPv6) and disable idle disconnection
Option #1:
If no local network, do the following: Open Control Panel -> Network and Internet -> View task network status. Or you can click on the Internet connection icon in the tray -> Network and Sharing Center.
Left-click on “ LAN connection" and select "Properties".
Uncheck Internet Protocol Version 6 (TCP/IPv6) and click OK. If in addition to the local network you have other types of connections, then continue further:
Click right click mouse on the connection you created and select "Properties".
Go to the Options tab. In the drop-down list of the “Idle time before disconnection” parameter, set the value to “never”.
Go to the Network tab, uncheck Internet Protocol Version 6 (TCP/IPv6) and click OK.
Prohibition of turning off the network adapter to save energy (This is mainly found in laptops)
Option #2:
Open “Device Manager” (Right click on my computer -> Properties ->
Open Network Adapters. Right click on your network adapter and select "Properties".
Go to the "Power Management" tab and uncheck the "Allow the computer to turn off this device to save power" checkbox.
Configuring network adapter settings
Option #3:
- Open “Device Manager” (Right-click on my computer -> Properties -> On the left, click on the Device Manager link).
- Open Network Adapters.
- Right-click on your network adapter and select “Properties”.
Now we need the "Advanced" tab. Set Flow Control to Disabled and click OK.
Entering IP parameters manually
Option #4:
Open Control Panel -> Network and Internet -> View network status and tasks.
In the window that appears, click on the “Change adapter parameter” item.
Now right-click on “Local Area Connection” and select “Disable”.
Right-click on “Local Area Connection” and select “Enable”.
Right-click on “Local Area Connection” and select “Status”. Click on the "Details" button and write down the specified values.
Click on the "Close" button and then click on the "Properties" button. Click on “Internet Protocol Version 4 (TCP/IPv4)” and click the “Properties” button.
Enter the previously recorded IP parameter values manually and click OK.
Resetting Windows 7 local network settings
Option #5:
Run Command Prompt as Administrator. In the search bar of the Start menu, enter the command: cmd and press Ctrl+Shift+Enter at the same time. Enter the commands below one by one, pressing the Enter key after entering each one.
route -f
netsh winsock reset
ipconfig /renew "Local Area Connection"
If after performing the above steps the connection to the network is lost, check the entries in the Event Log:
Go to Control Panel -> All Control Panel Items -> Administrative Tools and open Event Viewer.
On the left side of the snap-in tree, open Event Viewer (Local) -> Windows logs and check in each of the subsections: Applications and System whether any error related to the connection loss was described. Also contact your ISP support and check Windows 7 local network settings.
Thank you for your attention, good luck everyone!!!
If you have several personal computers, or a computer and laptop, and you want each of them to be connected to the Internet, then you will need to organize a local network through which all devices will have access to the global network.
Local network for exit and global web
To connect to a local network, it is absolutely not necessary to use a desktop computer. It is also possible to connect a laptop to it. The following steps are intended to Windows program XP, but the same ones can be produced for any other system.
To create a home network, you first need special equipment, and in particular, a switch and network cables. Below you can see a photo of the necessary equipment. 
Also, all devices need to have network cards built into the board. She is also shown in the photo below. 
And of course, not a single local network can do without the modem itself. It is demonstrated below. 
Please note that the network card must be installed in a computer that has access to global network directly. This computer will subsequently serve as a server. The system independently detects new equipment - a network card and installs the necessary drivers.
After this, we connect a modem to the installed network card and configure Internet access.
We connect one end of the network cable to the second network card of the server, and connect the other to the switch. Next, we connect the network cables to the network cards of desktop computers or laptops. The picture below shows how it should look. 
Now we connect the free ends of the network cables to the switch and connect them to the electricity network. You may notice that signals appear on all connected screens indicating that the cables are ready to be connected. The photo shows an example of messages. 
Let's start setting up the network itself. First of all, we set up the server. Go to Start, select Settings, then Control Panel, then Network connections.. Renaming the old network card to avoid confusion in the future. Next, you can see the icon of the renamed network card to which the network cable is connected. We look at the network settings. To do this, click on the map icon and select the “properties” menu item. Below you can see what it looks like. 
After this, a new window will open on the screen. The name of the window is “LAN – properties”, since for the example we called our network card LAN. The photo below shows what this window looks like. 
We look for the “General” tab and click “Internet Protocol”. Or you can simply select this line and click “Properties”. You will see a window called “Properties: Internet Protocol (TCP/IP)”, it is shown in the photo below. 
We make the entry “Use the following IP address:” active and assign an IP address to the server using a modem. It is better to write the following numbers: 192.168.0.1. We save everything changes made by clicking OK. Check that everything is the same as in the picture below. 
After that, check the last two items. This will allow you to immediately detect the wire coming off for various reasons. Save everything again by clicking OK. The server setup is now complete. Let's start setting up the rest of the local home network equipment.
To do this, first select the “LAN” icon, as shown below. 
After that, click the next house icon, which is shown below. 
A setup wizard will open on your screen. He will help you quickly and correctly set up. Click “Next”. Below you see an example of a wizard. 
Then a new window will appear, where you also need to click “Next”. 
In the window that appears, check the box next to “Other” and click “Next” again. 
Check the box next to “This PC is part of a network that does not have access to the Internet” and click “Next”. A new half-empty window will appear, as in the image below. 
Write your name in big or small in English letters and click “Next”. In the new window, specify the working group, as shown below, and click “Next” again. 
We do not change anything on the newly appeared page, we leave it unchanged. 
But here you will need to enter all the data that you previously used to configure the local network. If you think that you made a mistake on one of the points, you can always go back and eliminate the errors. If you think that everything is in order, go “Next”. 
Place a dot next to the “Finish the wizard” item. 
In the new window, click “Finish” and restart the computer. 
Similarly, we configure the network cards of the remaining computers on your local network that are not servers. The only difference you will encounter during operation is the name of each equipment. The names of the network cards must be different from each other. 
As the figure below demonstrates, we have different data installed on the new equipment. We write everything in the same way as shown below. 
After that, fill out the “Internet Protocol” for the following equipment. We also fill it out in accordance with the illustration below. 
As you can see, the data entered is the same. After this, our local network is configured. We configure a network card that connects directly to the modem.
So, in the previous article we figured out why the average user actually needs it. Let's recall the main concepts of this lesson:
- - a local network is a system of computing devices connected by communication lines, designed to transmit information to a finite number of subscribers;
- - there are three main types of local network topology, on the basis of which more complex local communication structures are built;
- - according to the way computers interact, local networks can be peer-to-peer (when all PCs connected to the network have equal rights) and with a dedicated server.
In this article we will look at how to create a local network with the same access rights for all its users.
The advantages of such a network include simplicity of design (setting up a home network is quite tough for a beginner) and economic availability of equipment, but the range functionality such a network is very limited.
So, to create a local network between computers we need:
Several computers (in in this case Let's consider a network option that unites more than two PCs, and we'll talk about it separately), which will become nodes of our local network. Each PC needs to check the presence of a network card (although most modern devices are equipped with a built-in “network card”, but “who the hell is not joking”...).
- - Network hardware. To organize local networks, both managed (customizable) and unmanaged network equipment can be used. To create a small home network, a simple unmanaged 4-6 port switch is quite suitable.
- - Network cable to connect each computer to network equipment. The total length of the cable directly depends on the final number of PCs, their distance from each other and the architecture of the room (building) in which the local network is created.
- - Connectors(RJ-45 connectors), the number of which also depends on the number of computers connected to the network. So, to crimp the cable for each PC you will need at least 2 connectors;
- - Swage(Crimper) – a tool for cable termination. (In its absence, many masters make do with improvised means (for example, a screwdriver), but it will be quite difficult for a beginner to perform this trick).
Creating and setting up a home network
1. Select the computer from which the creation of the local network will begin, and connect it to network equipment. To do this on both sides crimp the cable and using RJ-45 connectors we connect it to the ports of the switch and the network card of our computer.
Any additional settings an unmanaged switch does not require: we only need to register correct settings the local network itself in the operating system of each PC
2. To do this, go to the settings of the computer’s network card (read: windows 8 and windows XP) and write there IP-address of this PC. Typically, the following IP addresses are used here: 192.168.1., 192.168.0;
3. Repeat points 1-2 for each computer connected to the network.
Important: the last digit of the IP address of each subsequent PC must differ from the previous one (in the range indicated above): so, if the first computer was assigned IP 192.168.1.1, the second PC will have it 192.168.1.2, the third will have 192.168.1.3, and so on.
When all computers are connected, we check our local network for functionality.
You can do this in two ways:
Check for other devices connected to the network in the “ tab network» the control panel of this computer;
Ping any computer on this network with an IP address known to us. Pinging is carried out as follows:
Go to “Start→Run”, in the window that opens, assign the command “cmd” and press “Enter”;
In the window that appears command line we register ping xxx.xxx.xxx.xxx, where xxx.xxx.xxx.xxx is the IP address of the computer we are looking for.
If after executing the command we see a similar picture in the command line window, then the home local network we created is quite functional, but if the computer displays a message about “exceeding the timeout interval for the request” or that “ given node not available"
- must be searched and eliminated technical issues this network.
Hi all. Nowadays, almost every computer has access to the Internet. An Internet connection allows you to find and download the necessary information.
In addition, computers are connected to a local network. A local network has its advantages; using a local network you can transfer faster large files to another computer. Also files unlimited size can also be transmitted via the Internet. I wrote about this in the article -. I advise you to take a look.
In order to implement this method we will need additional equipment.
This necessary equipment will become a switch or router. The router serves to distribute the Internet channel for all computers connected to the network and also serves as a connecting link between computers. I talked about routers in detail in the articles:
The number of computers connected to the network is usually determined by the number of outputs on the hub, which varies from 8-16 or even more. This connection method, with certain settings, which we will talk about a little later, allows you to unite all computers with a single local network.
In addition, this connection allows computers to be on the network independently of each other. Even if one of the computers disconnects from the network, the rest will continue to work.
In order to implement a network through a hub, we will need a special network cable that will connect each computer to the network. This cable is also known as "twisted pair".
So, each twisted pair core is crimped and equipped with a special RJ-45 snap-in device. Installation of individual cores occurs in sequence as in the picture
After the wiring and connection of the wires from the PC to the hub is completed, you can proceed to the final process directly to the operating system settings.
Depending on what operating system installed on computers information provided dialog boxes may change, however general principle connections remain the same everywhere. In general, connecting via a local network will not be difficult for you.
2 How to set up a local network
First, we need to finally make sure that each wire is connected to the hub in the correct order. We can find out about the presence of a connection from the Control Panel menu - Network connections.
If there is no connection, you should check whether all ends of the twisted pair are crimped and whether the switch is connected to the power supply. So here we see that the computer icon has activated, this means that you can go to the settings.
After this, you need to select one of the active connections if there are several of them, right-click and go to the “Properties” menu item.
The dialog box that appears contains a list of components that are used in the process of connecting to the network. Select the TCP/IP protocol from the list and go to its properties.
Initially, all settings are unavailable because by default the network is configured automatically, which is extremely unnecessary for us. We activate the “Use the following IP address” switch and go to the available settings.
Select the edit fields below. The first field "IP address" specifies the virtual network address (this can be compared to your home address only in virtual space). The following values must be entered in the field: 192.168.1.x, where “x” is any integer from 1 to 255.
It is better to set the values based on their order; this will allow you to avoid confusing the addresses of computers located at home or in the office in the future.
After you have assigned all computers an IP address and subnet masks, you need to assign each computer its own individual name and workgroup.
This does not require special knowledge, everything is quite easy and fast. To carry out this operation, you will need to find the “My Computer” icon in Start or on the desktop go to context menu in "Properties".
Fill in the computer name and working group arbitrary names. Like in the picture for example. Confirm the changes by clicking the button OK.
Well, that's all, you have set up a local network. Restart your computer, and then proceed to check the network for functionality.
3 Checking the functionality of the local network
The fastest and easiest way to check is to enter the PING command. This command sends a request to the specified IP addresses, the received response is displayed on the monitor in the form of a report.
So, in order to implement this command go to the menu Start->Run, and dial cmd.
In the window that opens, enter Ping command 192.168.1.x where “X” is the computer number as indicated above, click Enter.
If a message appears on the screen "Request timeout exceeded" this will mean that you configured the network incorrectly, in which case you will have to recheck all connections to the switch.
In order to view computers connected to the network, you should do the following:
Go to my computer->folder "network environment" and press the button “Display workgroup computers”
As a result, local network computers should appear.
Also, you can type the address of a computer that is on your local network directly through Explorer, it looks something like this:
In addition, instead of a name, you can simply type the name of the computer on the network.
This way you can set up a local network. Good luck to you!
