How to connect a second computer?
Most people have the Internet at home, without which it is already difficult to imagine everyday life. At home, the Internet is used for a tablet, laptop, computer or mobile phone. Often a router is installed that provides wireless Wi-Fi. However, not everyone has a variety of devices through which you can connect to the Internet. Some people have two computers and want to connect both to the Internet, but don't know how.
Let's take a closer look at how to properly connect a second computer to the Internet.
Connecting one computer to the internet is easy, but connecting two computers to the internet can be tricky. There are several ways to achieve what you want:
For this method, you will need a modem that will be connected to your ISP and configured correctly. To connect to the Internet, it is enough to run a wire from the computer to the modem and insert it into any Lan socket that is free.
In addition, you may still have to install drivers on the computer's network card if it does not see the modem and Internet connection. Drivers can always be downloaded from the Internet or from a disk to a computer.
This method It is considered the simplest, but you will have to carry out and hide the extra wire to the apartment, which is not always convenient.
Connecting a second computer through a router occurs via a wireless Wi-Fi network. The computer can also be connected by wire, but again it will have to be led through the apartment.
To connect, you only need to buy and install the module wireless communication Wi-Fi, which is sold in any computer hardware store. For the connection to work, you must:
After that, the computer will connect and you can access the Internet.
If you do not have a router, and all LAN inputs on the modem are busy or the Internet is directly connected to the first computer, then in this case You can connect a second computer to the Internet through the first one. There are two ways to achieve this:
This method of connecting a second computer through the first one is quite complicated or expensive, so almost no one uses it.
If you need to connect a second computer to the Internet through a router ... then you already have one, you have already been visited by an Internet provider specialist (or you yourself created a local network, having received the settings in the provider's office) and there is a router at home.
Modern routers, as a rule, combine the functions WiFi router and a "wired" router, i.e. you can or "on the radio." , and a wired Ethernet jack (Ultrabooks may or may not have wired connectivity).
Most laptop users use WiFi connection, so as not to entangle the home with wires and be "mobile" within the apartment. But, if you use a high-speed (more than 10 megabit / s) Internet tariff, wired connection will fully realize its speed advantage ().
Desktop computers, as a rule, do not have a Wi-Fi adapter and will have to be connected to the router with a special network cable. If you love perfect order and beauty in the house and - even more so - if desktop computer need to be installed in another room, you can purchase it, which will reduce the number of cables in the apartment by one.
The reverse situation is also possible, although unlikely, when for some reason you need to connect via cable, but there is no Ethernet port on the computer (for example, it is broken). The USB interface will come to the rescue again - you can purchase an external Ethernet adapter that is inserted into the USB port. But the vast majority of modern motherboards has "on board" a built-in Ethernet adapter with a speed of 1 Gb / s.
The following figure shows options for connecting multiple computers to the Internet through one router:
We figured out the physical and link layers, now let's talk about the intricacies of connecting a second computer to the Internet via local network: i.e. about drivers and settings network protocols. Usually at the router, i.e. the router automatically assigns to the computer and "everything works by itself" after you enter the password for the Wi-Fi network or connect the router and the computer with a network cable.
In this case, the input wifi password and connecting the cable are equivalent in meaning. If you do not know the password for your wifi network- Maybe? it is in the papers left by the provider (in addition,).
As in the case of Wi-Fi and cable connection of the second computer to the router, if the connection is established, Windows will notify you in the tray. After that, you can launch the browser and check the Internet. If “by itself” did not work, then you need to check the correct installation of the network adapter drivers and the correct network settings:
1. Are the network adapter drivers installed correctly? Launch panel Windows controls(will help to do this), then find and launch the device manager and make sure that there are no alarm symbols near the network adapter icon, as in Fig.2.
If there are crosses or question marks, you need to reinstall the driver:
2. If everything is in order with the devices, but still, you need to compare the network settings on the first computer already connected to the Internet with the second one. It is possible that dynamic allocation of IP addresses is not used, and the address is set manually. In this case, to connect a second computer to the Internet, you need to set the same settings manually. most professional and fast way view network settings - ipconfig command. First you need to start the command interpreter (the old name is the ms dos session) by typing cmd.exe in the “run” line (we read). In the resulting window, type the ipconfig command. This must be done on both machines.
The main information that the ipconfig command will give is the IP address, and . By the way, Gateway is your router.
IP address. . . . . . . . . . . . : 192.168.1.100
subnetmask. . . . . . . . . . . : 255.255.255.0
Default Gateway. . . . . . . . . : 192.168.1.1
Important! The last digit of the IP address of the second machine must not match the address of the first machine, otherwise your network will have . The subnet mask settings and gateway address must be the same on both machines.
IP address settings are made in the TCP IP protocol properties window:
In our example - on the first machine 100, on the second 101. The number 100 is taken as an example, it can be any in the range from 2 to 253. If this requirement is met, then the Internet must work, if not, reboot and check and compare the settings again networks.
Note that if two computers are connected to the same router, then they can “see” not only the Internet, but also each other, i.e. you can either just watch movies, photos or listen to music over the network using one of the computers as a home server.
Wired connection or Wi-Fi - it doesn't matter. Network access settings can be made by running the wizard home network. By the way, watch movies from a computer disk connected to the network, if you install any file manager with local area network (LAN) support.
In the previous article, we talked about how to make a network cable (patch cord) with your own hands. Suppose you are lucky to become the owner of not one, but two computers, and then, as luck would have it, new problem, which did not exist before the acquisition of a new computer: it became necessary to connect two computers to each other.
What is it for? Well, for example, if you need to move files from one computer to another, so as not to run around with a flash drive between them (and if the files are large, and there are a lot of them, and the flash drive is modest), you can create a shared folder on one of the computers and drop everything you need there. You can also use one printer and print to it from any computer. And most importantly, you can use one Internet connection for two computers.
In short, there are many advantages, there is only one drawback - network cards in computers will be busy, and if the modem for Internet access is connected via a LAN connector, that is, to a network card, then in order to connect two computers to each other, one of them needs will deliver another network card. If the modem is connected to the computer via a USB connector, then nothing needs to be delivered.
So how do you connect two computers together. All actions were carried out on Windows 7 and Vista, but the main thing here is to know the procedure, and you can repeat it on any OS. We turn on two computers, and connect them with a network cable. Next, open My Computer on one of them, click right click on any empty area, select Properties. Next, we get to the window System. In this window, click on the button Change settings, next to the computer name.
Here we are on the tab Properties of the system, where we are interested in the Change button, click it. After we clicked the Change button, a window appears Changing the computer name or domain. In the "workgroup" line, you need to check the box and write the name of the workgroup that you are creating. If the computers belong to the same working group, then they "see" each other, that is, on the second computer, you will need to specify the same workgroup name. You can think of any name, most importantly, it is written in large with Latin letters. We press the OK button.
After we will see the system message: " Welcome to the working group... (here is your workgroup name)", press the OK button, and a message will appear stating that in order for the changes to take effect, you must restart the computer, agree, and press OK. If you close the window Properties of the system, a message will appear asking you to confirm the reboot. We restart the computer.

In order to connect two computers to each other, on the second computer, you need to repeat all the steps that were done on the first one and write the same workgroup name.
After all the above actions have been done, you still need to make the settings for the created workgroup. To do this, you need to go Control Panel, and open there. Now the two computers are connected to each other, but in order to see the folders, as well as printers on one and the other computer, you need to enable "Network discovery", "File sharing", "Sharing shared folders", "Usage shared printers", and it's also important to disable "Password Protected Sharing".
If one of the computers is connected to the Internet, then in order for it to be on the other, you need to make some more settings for the Internet connection. In control window network connections need to choose Network connection management. In the window that opens, find LAN connection, right-click and go to the properties of this connection.
In the connection properties window, go to internet protocol version 4 properties And internet protocol version 6. In order to do this, you need to left-click on one of the items (it will be highlighted in blue) and click Properties. In the protocol properties you need to set " Obtain an IP address automatically". We do the same on another computer.
And finally, the last and important action that needs to be done. In order for the Internet connection to be on another computer, you need to allow other network users to use this connection to access the Internet in the connection properties on the computer that is connected to the Internet. For this you need to open Network connections, and there select the connection that is used to connect to the Internet.
Next, you need to right-click on the icon for this connection, and select Properties. In the Properties window, select the Access tab, and check the box next to "".
Good day, dear readers.
If two computers are used nearby, it is logical to make a local connection between them. Windows networks 7. It is convenient to share files, information, play games together or use 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 technologies. As mentioned at the beginning, technology allows the exchange of information, and generally helps to speed up the workflow.
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, it is necessary to the right computers enable the ability to discover individual folders.
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
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:
Each user who is already for a long time interacts with other devices in this way, at least once in my life I met a problem when the connection simply disappears. This can happen for several reasons. The most common problems are 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.
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 Windows work And computer technology generally.
I welcome all visitors.
Nowadays, many people already have several computers at home, although not all of them are connected to a local network ... And a local network gives very interesting things: you can play network games, exchange files (or even use a common disk space), work collaboratively on documents, etc.
There are several ways to connect computers to a local network, but one of the cheapest and easiest is to use a network cable (ordinary twisted pair), connecting the network cards of computers with it. Here's how it's done and we'll cover it in this article.
1) 2 computers with network cards, to which we will connect the twisted pair.
All modern laptops (computers), as a rule, have at least one network card in their arsenal. The easiest way to find out if you have on your PC LAN card- is to use some utility to view the characteristics of the PC (for such utilities, see this article:).
Rice. 1. AIDA: to view network devices, go to the Windows Devices/Devices tab.
By the way, you can also pay attention to all the connectors that are on the laptop (computer) case. If there is a network card, you will see a standard RJ45 connector (see Fig. 2).
Rice. 2. RJ45 (standard laptop case, side view).
2) Network cable (so-called twisted pair).
The easiest option is to simply buy such a cable. True, this option is suitable if your computers are not far from each other and you do not need to run a cable through the wall.
Rice. 3. 3 m cable (twisted pair).
(The description will be based on Windows 10 OS (in principle, in Windows 7, 8 - the settings are identical). Some terms are simplified or distorted in order to more simply explain specific settings)
1) Connecting computers with a network cable.
There is nothing tricky here - just connect the computers with a cable and turn them both on. Often, next to the connector, there is a green LED that will signal you that you have connected your computer to some kind of network.
Rice. 4. Connecting the cable to the laptop.
2) Setting the computer name and workgroup.
Next important nuance- both computers (connected by cable) must have:
To set these settings, go to " MY COMPUTER» ( or this computer), then anywhere click the right mouse button and in the pop-up context menu, select the link " Properties". You will then be able to see your PC name and workgroup and change them ( see green circle in fig. 5).
Rice. 5. Set the computer name.
After changing the computer name and its workgroup, be sure to restart the PC.
3) Configuring the network adapter (setting IP addresses, subnet mask, DNS server)
Then you need to go to the Windows control panel, address: .
Actually, next you should see your network adapter, if it is connected to another PC with a cable, then no red crosses should be lit on it ( see fig. 6, most often, the name of such an Ethernet adapter). You need to right-click on it and go to its properties, then go to the protocol properties " IP version 4» ( you need to go into these settings on both PCs).
Rice. 6. Adapter properties.
Now on one computer you need to set the following data:
Rice. 7. Setting up IP on the "first" computer.
On the second computer, you need to set slightly different parameters:
Rice. 8. IP setting on the second PC.
Next, save the settings. Directly setting up the local connection itself is completed. Now, if you go to the explorer and click the "Network" link (on the left) - you should see the computers in your workgroup ( however, while we have not yet opened access to files, this is what we will do now ...).
This is probably the most common thing that users need when they join a local network. This is done quite simply and quickly, we will consider everything step by step ...
1) Enable file and printer sharing
Go to the Windows Control Panel along the path: Control Panel\Network and Internet\Network and Sharing Center.
Rice. 9. Network and Sharing Center.
Next, you will see several profiles: guest, for all users, private (Fig. 10, 11, 12). The task is simple: enable file and printer sharing everywhere, network discovery and remove password protection. Just set the same settings as shown in fig. below.
Rice. 10. Private (clickable).
Rice. 11. Guestbook (clickable).
Rice. 12. All networks (clickable).
An important point. You need to make similar settings on both computers on the network!
2) Disk/folder sharing
Now just find the desired folder or drive that you want to give access to. Then go to its properties and in the tab " Access» you will find the button « Advanced setup“, and press it, see fig. 13.
Rice. 13. Access to files.
In advanced settings, check the box next to " Share a folder' and go to the tab ' permissions» ( by default, read-only access will be granted, i.e. all users on the local network will only be able to view files, but not edit or delete them. In the "permissions" tab, you can give them any privileges, up to complete removal all files...).
Rice. 14. Allow shared access to the folder.
Actually, save the settings - and your disk becomes visible to the entire local network. Now you can copy files from it (see Fig. 15).
Rice. 15. File transfer via LAN…
It is also a very common problem faced by users. As a rule, one computer in the apartment is connected to the Internet, and the rest get access from it (unless, of course, a router is installed :)).
1) First, go to the tab " network connections » ( how to open it is described in the first part of the article. It can also be opened by entering the control panel, and then in search line enter "View Network Connections").
Rice. 16. Sharing the Internet.
