How to connect a laptop to a computer to transfer data. Connecting a laptop to the Internet via cable


A laptop is great for its mobility, and it is this feature that distinguishes it from desktop computers. You can carry it with you wherever you need it. Sometimes the question arises about wireless communication if, for example, you come to visit friends who have their own laptop in order to send some information to it. If there is a Wi-Fi router, then the problem disappears very quickly, that is, there are no difficulties with this procedure. However, the question of how to connect a laptop to a laptop wirelessly becomes much more relevant if not network devices, and I don’t want to buy them at all for subjective reasons. Here everything is solved quite simply.

The situation with modern devices

Over the past decade, all portable devices have come with built-in Wi-Fi module. Therefore, when deciding how to connect a laptop to a laptop wirelessly, it does not arise special problems. IN in this case You will not need any financial expenses at all. This way you can combine several devices into one network without even resorting to using any special software - Windows 7, 8 and 8.1 already have everything you need.

Network creation

First you need to choose one laptop that will serve as the basis for the software. wired network. You should run a command prompt on it with administrative rights. Now you need to dial certain commands. A wireless network with a password is created as follows. IN command line you need to enter netsh wlan set hostednetwork mode=allow ssid=[network name] key=[password]. The parameters specified in square brackets, you can install them as you want.

Settings

Once the network has been created and is already running, you need to register IP addresses on the devices. This is also quite difficult to do. You need to go to “Network Center” - “Change adapter settings”. When you find yourself in network settings device, you need to call context menu wireless network icon. Next you need to open “Properties”. In the window that opens, you should find “Internet Protocol Version 4 (TCP/IPv4)” and here you need to check the boxes to automatically obtain addresses.

Communication

After creating and launching a wireless network, you need to go to the “Wireless networks” item, where the created network will be displayed. You need to call up its context menu, in which you must select the “Connect” item. The system will prompt you to enter a key and the next device search request will require your consent. So, if we talk about how to connect a laptop to a laptop wirelessly, it should be noted that the device that became the source of the network will have an IP address of 192.168.173.1, and all others connected to it will be from the same subnet. Addresses appear in information about network connections. This connection option turns a laptop into a Wi-Fi router, to which you can connect three or more computers, laptops, tablets, smartphones or other devices. You can even distribute the Internet from it. That's all for the question of using WiFi. There are other options that are no less relevant.

Creating a wired network

So, if you are wondering how to connect laptop to laptop via (Windows 7), then this is worth considering. This method is suitable in cases where one of the devices does not have a wireless connection module or does not work, or this element is used to connect to the Internet. How to connect a laptop to a laptop via WiFi has already been discussed, now you should determine how to do the same only using twisted pair. Every laptop has a network card. You will only need to purchase a LAN cable of a certain length; it is called a crossover because of the way it is crimped.

Connection cable

The network cable can be crimped in one of two ways - direct and reverse. The first is used to pair a laptop with a router, switch or modem. A crossover is focused on connecting two similar devices to each other. A network cable crimped using the second type differs in that the pairs of wires in it have been swapped. It can be purchased at any computer store. One end should be connected to the network card of the first laptop, and the second - to the other.

After such manipulations, you can further consider the question of how to connect a laptop to a laptop via local network. To do this, you need to enter the Network and Sharing Center, where you need to change the adapter settings. You must open the "Properties" of the local network connection. Next, in the window that opens, you need to select “Internet Protocol version 4 (TCP/IPv4)”. Now you should register special addresses and subnet masks on both devices. After all these manipulations, the gadgets will be visible to each other in network environment.

Alternative options

You can also consider the question of how to connect a laptop to a laptop via USB? It is worth noting that this connector allows you to connect two devices directly, but it can hardly be called convenient. USB-Link cables come in two types. The simplest one only allows you to see the contents of a second computer that is connected in this way from a program that simulates a standard system explorer. From this program you can drag files onto your computer using the mouse. The second is more complex, representing in fact a pair of USB-to-EtherNet type controllers connected to each other by a network cable. In this version, you will get the classic network connection, but if both computers have built-in network adapters this method can be called an unnecessary entity: it is cheaper, easier and much faster to use a traditional network cable or transfer data using regular flash drive. If we talk about how to connect a laptop to a laptop via USB, it should be noted that the speed of such a connection will be very low, which negatively affects the work. The ease of use of a regular flash drive and its availability for purchase simply negate all the convenience of connecting devices directly.

Bluetooth

Bluetooth is another method of communication between a pair of devices. This method can hardly be called good, since the data transfer speed is no more than 723 kilobits per second, and the range is quite small. In addition, the network in this case is difficult to set up, it is characterized by poor interference and burglary immunity, which makes it too inconvenient for transferring data between two computers.

Additional ports

LPT-Link provides direct cable connection via Historically, this method is one of the first, since it does not depend on the installed operating system, so it can be used anywhere. On this moment it is dying out due to the fact that the interface itself is practically not used. For example, if you are wondering how to connect a laptop to a laptop via hdmi cable, then it is worth noting that it is more realistic to connect them through parallel ports. The HDMI interface is designed to connect a TV to a computer to output images and sound; it is not intended for transmitting other data. And where there are LPT ports, you can use them without any problems. The cable length in this case is limited to three meters, and the speed can reach 2 megabytes per second.

Serial port

The answer to the question of how to connect a laptop to a laptop via an HDMI cable can be answered unequivocally: no way. However, there are several more quite available ways connecting devices to each other. One of them is the serial port. This method can also be considered one of the oldest, but this has not lost its popularity. This interface is gradually becoming unusable due to the low data transfer speed, as well as the death of the COM port itself, which is simply inconvenient to install on portable devices. But it has a much greater chance of being used for a direct connection than HDMI.

Indirect methods

Knowing what ports laptops have, you may be wondering how to connect a laptop to a laptop via VGA cable? And here the answer is also unequivocal - it is simply impossible to do this. But if you want to use some the hard way, you can resort to transferring data using additional storage media, for example, disks, flash drives, external hard drives and others.

U computer users Sooner or later there may be a need to connect two or more computers to each other. You need to connect a friend’s laptop to your computer, or you had one computer at home and bought another, or you need to use your computer as a means to distribute the Internet to other PCs - there can be a lot of options. In this material I will tell you how to connect a computer to a computer using a connection via network cable, Wi-Fi and USB.

The easiest way to connect is to connect two computers via a network cable. Network cards are now built into almost all models of desktop computers and laptops, and if suddenly for some reason you don’t have one, then you can always purchase it at the nearest computer store or order it online.

Make the cable yourself. Since two types of crimping network cables (twisted pair) are now used, you will need “computer-to-computer” crimping, so-called “crossover”. Of course, you can crimp it yourself using special tools, but I would advise you to contact any computer company where they will do this for you in a couple of minutes at a cheap price. Don't forget to indicate that you need a crossover, and also indicate the required comfortable length of your cable.

When you have such a cable, one end of it must be connected to one computer in the connector network card, the other end - into the same connector of another computer. After connecting the computer to the computer, you need to go to the settings of these computers and configure the connection between them.

How to connect computer to computer via cable:


Checking PC to PC connection. The computers should now be visible to each other.


The main part of the work is done. Now you can play computer games with each other, your machines will see each other. But if you want to send files to each other, then you need to make some directory on your PCs common so that both your computers can write to or read the necessary files from there.

Let's share the folder. When you have determined which folder on your computer will be shared, right-click on it, select properties, go to the “Access” tab, click on sharing, and in the user column, click on the arrow on the right, select “Everyone”. Click on “Add” on the right, and then on “Sharing” at the bottom. Your folder will become accessible to another computer, the user from there will be able to download files and upload their own there.

By the way, the same mechanism applies both to a separate directory and to the whole logical drive, which can also be made general using the above technique.

Method 2. How to connect a computer to a computer using a homegroup

You can also connect our machines to each other by creating the so-called. "home group" We connect the laptop to the laptop using a network cable, indicate their IP and the desired subnet mask as described above.

  1. After specifying the parameters on both computers, go to the control panel, there select “Network and Internet”.
  2. Next, go to the Network and Access Control Center, and at the bottom left click on “ Home group».
  3. In the window that appears, click “Create a home group” and click “Next”.
  4. Selecting groups of files for public access(videos, pictures, etc.).
  5. Again, click on “Next”, and in the next window we receive a password to access the group (you need to write it down).

Now any other computer can join our group if they know the password. To do this, you need to enter the “Home Group” component on another computer (the path is indicated above), and click “Join” there, following the wizard’s prompts. That's all.

Method 3. Connect computers using Wi-Fi

Typically, this connection option is used when connecting laptops to each other, which by default (unlike desktop PCs) are equipped with built-in Wi-Fi modules.

  1. To configure the computer-to-computer connection settings, go to control Panel.
  2. Then go to "Network and Internet", then click on the network control center, where on the left select “Change adapter settings”.
  3. Right-click on the icon "Wireless Network Connection", then click on "Properties".
  4. There we select the Internet protocol fourth version, double-click on it and put a checkmark on automatic receipt IP and DNS, then press "OK".

These operations must be performed on both computers. After this, we need to create a wireless network.

Click Start, type in the search bar, right-click on the command line icon that appears and select run as administrator in the menu that appears.

On the command line we type:

netsh wlan set hostednetwork mode=allow ssid= droidovtest.mcdir.ru key=458654452

You can use a different network name instead, and instead 458654452 – another password if desired.

The launch of our Wi-Fi network is carried out by the team netsh wlan start hostednetwork

Now go to another computer, click on the icon wireless networks(bottom right of the screen), in the list of networks we see the network under the previously specified name, click on it and click “Connect”. The system will ask for a password, and after entering it you will be connected to the network with the first computer.

Method 4. How to connect a computer to a computer via a USB cable

I’ll say right away that connect one computer to another viaUSB-the cable will not work directly, since the wiring itself USB cord made in such a way that there must be a master and a slave device. To create such a connection, you will need a special USB cable with a built-in chip, which are sold on various websites.

Typically, such a cord comes with a disk with drivers that ensure operation. of this device. If drivers are not included, they can be supplied automatically by the system itself. The cord may also include a file manager specially created to provide the functionality of this device. With its help, you can easily exchange files, just run it on both computers.

  1. After connecting and installing drivers, additional network adapters will appear in your network connections.
  2. Let's go to Network Sharing Center along the path described above, we find our appeared virtual adapter and by right-clicking on it select Properties.
  3. And then double click on Internet Protocol 4 versions, and set the address IP168.3.1 (standard subnet mask) on one computer, and 192.168.3.2 (same mask) on the other.
  4. We confirm and exit, now in the network environment of each computer we will see another computer.

Conclusion

As you can see, there are simple methods for connecting a computer to a computer using a power cord, wireless connection or USB connection. Usually, a crossover of a regular cord and a couple of settings is enough so that computers can see each other, and their users can enjoy joint gaming or sending to each other various files. If you find this difficult, just try to follow the above tips, you will definitely succeed.

Laptops can act not only as laptop computer for work. By connecting your laptop to your TV, you can turn it into a media center, watch streaming video from your favorite services, including YouTube, or play files stored on your laptop disk. You can play games on big screen or edit documents without straining your eyes. Read this guide to learn how to connect your laptop to your TV.

Steps

Part 1

Determining the connection type

    Determine what type of video output your laptop has. Exist Various types video outputs; in addition, your laptop may have several of them. out The video output is usually located on the side or back edge of the laptop. If you want to connect a MacBook to your TV, check out this article.

    • The VGA connector looks like a rectangle with rounded corners, with 15 contacts - 3 rows of 5. With its help, the laptop connects to the docking station.
    • The S-video connector is round, with 4 or 7 pins.
    • The composite video connector is a round RCA plug, usually yellow.
    • The DVI port is square, with 24 pins, 3 rows of 8 pins. It is designed to transmit a signal high resolution.
    • HDMI port resembles USB port, but thinner and longer. It has been installed in laptops since 2008 and is also designed for high-resolution signal.

  1. Check what video inputs your TV has. This depends on whether you have a standard or high definition TV. Typically, video input connectors are located on the back wall of the TV, but can also be installed on the side wall.

    Choose the right cable to connect your laptop to your TV. If you have multiple connection options (such as VGA, S-video and HDMI), use the one that gives the most high quality. HDMI- standard port in all new laptops and TVs, provides high quality signal and requires minimal settings.

    If necessary, get an audio cable. Some computers and TVs can be connected to carry audio and video with a single cable, but most will require video/audio connections using separate cables.

    Part 2

    Connecting the laptop to the TV

    1. Turn off your laptop. If the connection is made using one of the older types of connector, it is recommended to turn off the laptop when connecting to the TV. When connecting with using HDMI There is no need to turn off the laptop.

      Connect the video cable to the appropriate connectors on your laptop and TV.

      Set your TV to the correct input source. Most inputs on the TV are labeled. In the TV menu, select the input to which your laptop is connected. If necessary, look at the instructions for the TV.

      • The TV must be turned on for the computer to recognize it as a monitor.

    2. Turn on your laptop. From now on, setting up your TV as a monitor will differ depending on the operating system you are using on your computer. Sometimes the picture on the TV will be displayed immediately, or the image on the monitor and TV will be duplicated. In some cases, there will be no picture on the TV yet.

      Set up your TV as a monitor. Many laptops have a dedicated “Display” button that you can use by pressing the Fn (Function) key. With this key you can toggle all available options displaying images on monitors. You can expand the image to both screens, duplicate the image to both screens, or turn on just one of your monitors (either your laptop or your TV).

      • Windows 7 and 8 users by clicking Windows keys+ P can bring up the Projector menu, which also allows you to select from the display options described above.
      • If you are unable to use any of the above options, click right click mouse on the desktop and select Properties/Screen Resolution. Use the Multiple Screens menu to choose how you want the picture to be displayed on your TV.

    3. If necessary, set the screen resolution. Often, the resolution on the screen and the TV is different, especially for older TVs. Right-click on the desktop, select Properties/Screen Resolution and select the screen whose resolution you want to change.

      • Most high-definition televisions (HDTVs) can display resolutions up to 1920 x 1080, but some are limited to 1280 x 720 (1366 x 768). All of these resolutions have an aspect ratio of 16:9 (widescreen).
      • If you do not see a normal image, you can turn off the laptop for a while and set the resolution before reconnection to the TV. If you choose the option to duplicate the image on both screens, then the monitor resolution must be the same as the TV resolution.

    4. Adjust TV scaling. Some TVs will try to correct for different aspect ratios by upscaling the image. If you see that the image on your TV is “cropped” at the edges, make sure this setting is disabled.

    • If your laptop is connected to a high-definition television (HDTV), you may only see certain elements on the HDTV screen and not on the laptop display. This is fine. To see these elements on the laptop screen again, turn off the TV.
    • If you have difficulty connecting all these cables, purchase a device for wireless transmission signal. It provides ease of use without running cables.

USB-to-USB option. To connect two computers via USB, you cannot use a simple USB cable A-A. Required special cable USB Smart Link, which is equipped with optocoupler isolation and a special controller chip that performs the function of a bridge. Installation and configuration of the driver is carried out automatically; after installing the drivers, the device is immediately ready for use; you only need to install a program - something like a file manager. A program is usually supplied with a cable and driver. USB Link. It allows you to transfer files from one computer to another, has a simple interface, which is divided into two windows: your computer and the remote one. There are two indicators in the lower right corner of the program, green color which indicates the establishment of full-duplex communication. When launched, it automatically searches USB devices Smart Link and tries to detect remote computer and a similar program running on it. After this, complete synchronization occurs file systems on all disks of both computers. The program operates in Hot Swap mode; when a second computer is disconnected and connected, it works automatically. Unfortunately, the supplied driver works stably and can be installed without problems only under the Windows 98 SE operating system, but this “plate” provides high data transfer speeds, as well as ease of setup and connection. Another solution for connecting two computers together is provided by PC-Link USB Bridge Cable Link-100. This is a USB cable with type A connectors on both sides and a thickening in which the board on the Prolific chipset is mounted. The PC-Linq program, a type of Link Commander, is installed along with the driver. Work and appearance programs are similar to USB Link, but it has the advantages of supporting operating systems Windows systems XP and Windows 2000.

The speed of data exchange between computers significantly exceeds the connection speed through a serial and even parallel port and is comparable to the speed of a local network at 10 Mbit/s. The problems of regular transfer of both small and large volumes of files, for example, between a laptop and a desktop computer, are successfully solved. Of course, such a set useful functions may seem insufficient. What about work support? computer games, joint network resources and access of all users to one Internet channel? All this becomes possible with the help of another device - the Link-200 model. It will allow you to organize a peer-to-peer network based on USB communication, to which you can connect up to 16 computers. Link-200 uses a controller and drivers from AnchorChips. The device is a small translucent box with a USB A cable integrated into it. On the other side of the box is equipped with a USB type B connector. Supplied with A-B cable and a floppy disk with drivers. To build the network, a star topology is used. One computer acts as the master, and the rest are under its control. This is due to the fact that the EZ-Link-based network has its own internal structure of its own digital names and connects to the regular network through drivers, which are bridges. It is possible to share printers and other peripherals, just like in a regular local network. You can also use this cable to connect your laptop to corporate network. To do this, you will need a computer that is already connected to the network and has a free USB port. In this configuration desktop computer will work as a gateway between corporate and USB networks.

As usual with USB devices, installation is very simple. The auto-installer will install necessary drivers And software EZ-Link manager. If a network has not been installed on your computer before, then you will have to enter the name of the computer under which it will be visible on the network. After installing the drivers, you need to restart the computer and only then connect the Link 200 to a free port. In settings Link drivers 200 in the Advanced section can be changed unique number computer under which it is visible on a USB network based on Link 200. EZ-Link manager will start every time the computer boots. If the computer is not connected to the network, the icon will be gray, and after connecting the Link 200 cable to the USB ports of two computers, it will automatically detect the presence of a connection, activate the network connection, and the icon will change color to blue. Working with a network based on Link 200 adapters is completely identical to working with a regular network: you can connect network drives and other network resources, launch network games via the TCP/IP or IPX protocol. Thus, Link 200 makes it possible to create a fully functional network at minimal cost. Installing and configuring drivers is very simple. At a relatively low price for a kit for connecting two machines, Link 200 creates serious competition for conventional network cards. Unfortunately, this decision So far it only works under Windows 98/95, but manufacturers promise to release drivers for Windows 2000 as well.

Another device, USBNet, allows you to connect two computers, building a network without installing network cards. Minimum Requirements to computers - Windows 98 and availability of USB. When using USBNet, computers on the network can sharing files, programs and peripheral equipment: floppy drives and hard drives, CD-ROM, printers, scanners, modems. USBNet is the ideal solution for small offices, network games and small home networks. The number of users in such a network can reach 17. Data transfer speeds are up to 5 Mb/sec. A special protocol is established USB connections, there is support for TCP/IP and other network protocols. The device is installed as a LAN adapter.

USB Smart link allows you to connect not only PC and PC, but also PC/Mac, Mac/Mac for work. When connecting via USBLink, just install the device driver on both computers and USB program Bridge cable. Using this program, you can transfer files and folders from one computer to another in much the same way as it happens in any of the file managers. But copying files can only be done in one direction - it won’t work at the same time. By the way, USBNet does not have this drawback. Device driver, all necessary network protocols and access services are installed automatically. Specific protocols, most often called USB-USB Bridge net, need to be installed only on external computer, which has a connection to the local network, and the installation will happen automatically - you just need to agree with the request: yes or no. Disadvantage of USBNet - low speed pumping: with the stated 5 Mbit/s, most often the result is 3 Mbit/s. But this is compensated by the ability to access not only files, but also applications of a second computer, as well as the use of a printer, scanner and other peripheral devices over the network. Differences in operating systems and processors of the connected computers do not affect their operation.

The laptop is often used as home computer, resulting in the problem of access to inexpensive internet, which has in addition high speed, is relevant for him. These qualities today are more closely matched by an Ethernet connection, so below we will tell you how to make correct settings Internet on a laptop.

Ways to connect a laptop to the Internet

Connect laptop to wired internet can be done in several ways:

  • via a USB modem, which is convenient, for example, in the country, but such a connection often does not provide sufficient speed and usually costs more;
  • using Wi-Fi if there is an access point, for example, when a Wi-Fi router can be turned on from desktop computer with the Internet;
  • this can be done via wired Ethernet networks, providing the highest speed, connection to which will be discussed further.

Cable Internet for a laptop is the fastest, but also the most inconvenient, since in fact it can make mobile computer stationary. At the dacha, for example, it is better to turn on a simple USB modem. A Wi-Fi router is very useful for use in an apartment.

Preparing for cable internet connection

To set up an Ethernet connection, first connect the network cable to your laptop. You can also connect a router to it, which, after configuration, will be able to distribute Wi-Fi to any other devices, providing fairly decent speed.

The wire " twisted pair» is laid from the switch in the entrance to the place where you plan to make an access point to the Network. Using a special tool, a plug with an RJ-45 connector is mounted on the cable, which must be plugged into the corresponding socket on the panel on the side of your laptop.

Connecting to the Network will not be possible without the necessary drivers for the network card. To check that they are installed correctly, do the following:

  1. Windows XP. Go to the control panel by clicking “Start”, select the network connections section.
  2. For Windows 7 and older versions. Go from the control window to the network and sharing settings section, then select the option to change settings for the adapter.

If the window that opens is empty, the driver is probably not installed.

General rules for connecting high-speed Internet

The data required for connection is specified in a special agreement. If you want to turn on the router, you will need to make other settings described in the specifications for the device. If automatic detection network does not work, you will have to configure the TCP/IP protocol yourself.

In Windows 7 and 8, the connection is made in the following order:

In Windows 10, the connection is made as follows:

  1. From the Settings section of the Start menu, go to Network and Internet.
  2. Next, you will need to open the adapter settings settings.
  3. Next, follow all steps, starting from step 3, described for Windows 7 and 8 systems.

No further actions are required - the connection should work at full speed automatically. If you are connecting via a router, the procedure may vary for different providers, so to set up the Internet, first find out full information on the corporate website of the provider providing this service.

Alternative Internet for a summer residence

Note that at the dacha, where it does not appear possible connection to the Internet via cable, optimal choice will use a USB modem. As a rule, there are no problems with its connection:

  1. Insert a SIM card into the modem, then connect the device to the laptop;
  2. The system will detect a new device and offer to install a program that allows you to use a modem on your device;
  3. You may then have to enter the PIN code indicated on the card, after which the modem will automatically connect the laptop to the Internet.

In a word, you can connect to the Internet, which would have high speed even in the country, through a cable or router, and the procedure for setting up the connection can sometimes differ slightly.
