How can two laptops be connected to each other? Where will it be faster? Connecting laptops via Wi-Fi Connect 2 laptops to each other

Often, laptop users need to connect two devices together. There are several ways depending on how well you are with this type of technique. Before pairing a laptop with a laptop, be sure to check all the options to choose the one that suits you best.

Wi-Fi as a way of synchronization

Perhaps the easiest and most affordable way to connect two laptops is to connect via. It does not require any special knowledge, you just need to follow the simple instructions step by step, even if you absolutely don’t understand anything about this method of synchronization. It is noteworthy that if at least one of the computers has access to the Internet, then the second device connected to it can automatically get into the network.

1. Set up PC # 1 as for regular connection to Wi-Fi. Turn on the router, open "Network Connections" in the laptop, create a new wireless network, if it did not exist. At all steps of the connection, agree with what the system offers. Attention: if you want to access the Internet on device # 2, then at the last step, check the box next to "Allow access to the network for other users."

2. On device # 2, configure the following parameters in the "Network Connections" tab: "Internet Protocol TCP / IP" window, "Properties" tab IP 192.168.0.2; "Subnet mask" 255.255.255.0; The "main gateway" should be like device # 1 (you can see it in the same tabs on a configured laptop). Whatever the system tells you, choose these values, agree with everything.

3. On device # 1, create another wireless connection with any name (this will be your home network, that is, the place where both PCs are connected). Use any word or set of numbers as a key, but be sure to write it down so as not to forget. Before connecting the laptop to the laptop, check the "Direct connection" box, and also disable automatic key entry (it is easier to do it manually).

4. On device # 2, repeat step three so that laptops have one common network where they can see each other. This is where the created key is needed to connect them without any wires.

5. Test the visibility of the devices to each other. This is not difficult: in the active Wi-Fi zone on each of the laptops, a window should appear with a notification about the presence home network(current connections).

Possible problems include the following: it blocks a network foreign to it (the one you created), which means it prevents devices from synchronizing. Just turn it off on both laptops.

in a couple of clicks

This method is simple, but there is no guarantee that it will be possible to access the Internet from both devices. For example, one will be connected to the network, and the second will act as it will take several simple steps and clicks to connect two independent laptops.

It is not so important what kind of company they are, with what operating system (if this is one Windows family, Certainly). This method is ideal for those who often and a lot need to transfer information (of any format) from one device to another. Before connecting 2 laptops, distribute information on them into folders. In the future, this will significantly reduce your time.

Step 1: creating a homegroup

On any laptop, go to the "Control Center" folder. For convenience main laptop will be number 1. Click on the "Network & Internet" tab, then "Homegroup". If you have not previously created it (for any purpose), then this must be done. Click on the "Create a home group" button.

Step 2: defining folders

Windows will present you with several folders to choose from, which will be visible to your homegroup. Check the boxes where you require. If your personal devices are connected, then there is nothing terrible in putting down access everywhere. In any case, then you can still add folders for general viewing in the homegroup at your discretion.

Step 3: creating a password

For security purposes, the system will give you a password, which can then be used to connect the second device to the home group. Write it down. Your group is ready immediately after clicking "Ok".

Step 4: joining a homegroup

Before connecting the laptop to the laptop, make sure that they are (not so important how). Without this, it is impossible to create an environment for the "communication" of devices. On device # 2, go to " Home group"Similar to step 1, click" Join ". Enter your password, allow access to the desired folders, click "Ok". After that, you can safely send files from one device to another, but to strictly specified locations on your hard drive.

Of course, these are far from the only ways of how to connect a laptop to a laptop, but the simplest and most affordable, at no extra cost. As, for example, in the case of a cable, which you need not only to buy, but also to choose the right one, otherwise there is a risk of spoiling both devices.

Imagine life modern man without use computer technology it is difficult, since it has "penetrated" into almost all spheres of his activity. Laptops are especially popular due to their compactness and amazing mobility. For this reason, many, when going on a visit, will certainly take a laptop with them in order to seize the opportunity and demonstrate the uploaded photos, videos, and more.

Users no longer want to use external media information

Also, laptops are active assistants in solving production problems. However, there may be situations when you need to provide communication between two laptops in order to quickly transfer important data. Using disks or flash drives is quite inconvenient, since it takes a lot of time. For this reason, it is important to figure out how to connect a laptop to a laptop, which should be purchased in advance. There is enough simple ways connections that involve providing communication via cable or Wi-Fi networks.

This connection method is only suitable for those laptops that are equipped with Wi-Fi modules. However, it should be noted that all modern laptops have such a wonderful function, so you can connect wirelessly in almost every case.

In addition, the connection via Wi-Fi is popular among users, since it does not come with any additional financial waste.

Wi-Fi connection

So, having outlined the task associated with connecting two laptops to each other, it is now important to figure out technically how to connect a laptop to a laptop via Wi-Fi.

Connecting laptops via Wi-Fi is also good in that it allows you to provide a single network not for two, but simultaneously for several laptops, tablets or smartphones. At the same time, it is absolutely important that the user does not even have to worry about an additional installation. software... In modern operating rooms Windows systems 7 and 8 have already installed the software to make the wireless connection easy and hassle-free.

So, in order to navigate how to connect a laptop to a laptop, initially determine the laptop on which the wireless connection will be established.

Having decided, the user enters the "Start" menu, then at the bottom there is a search bar, in which you should type the phrase "command line". After the search is completed, the necessary utility will be displayed in the upper part, by clicking on which it opens on behalf of the administrator.

If you have not logged in from the administrator, you should call the utility again, and then click on it right click mouse, initiating the call of the context menu, in which it is easy to find the line "Run as Administrator".

In the opened command line a command is prescribed aimed at creating a wireless network using the Wi-Fi module. To this end, the user writes: netsh wlan set hostednetwork mode = allow ssid = "..." key = "...". Instead of quotation marks and ellipses, you must specify the desired network name and password to prevent unauthorized use of the network by unauthorized users.

To complete, retype the new command: netsh wlan start hostednetwork. This completes the process of creating a wireless network. However, the following steps should also be followed to ensure that all connected laptops function correctly.

It is very important to change adapter parameters wireless by registering the receipt of the IP address and DNS server automatically. These two important options are set on the Internet Protocol Version 4 (TCP / IPv4) tab.

At this point, all kinds of wireless options will be displayed in the lower right corner of the laptop display. Select the required network name, agree with automatic connection and enter correct password, which can be automatically memorized so that every time you enter, you do not need to dial it.

This connection option is also good because the main laptop itself acts as a Wi-Fi router, successfully distributing the Internet to connected devices.

Wired connection

You can connect multiple laptops without going through a wireless connection via Wi-Fi. However, in this case, you will have to visit a specialty store and purchase a special HDMI or RJ-45 cable. After a successful purchase, it will be useful to familiarize yourself with the recommendations on how to connect your laptop to your laptop using an HDMI or RJ-45 cable.

Cable connection

Many users wonder if it is possible to connect laptop to laptop via HDMI. To answer this question, it doesn't hurt to figure out what an HDMI cable is.

HDMI cable provides communication between household appliances... In most cases, an HDMI cable is used when there is a desire to connect a computer or laptop to a TV, since the main functional task of an HDMI cable is to transfer audio and video signals.

Since HDMI guarantees high speed and quality of video and sound transmission, users actively use it when connecting two devices that support a network connection via HDMI.

If users want to avoid the problems associated with connecting devices via a network via HDMI, it is rational to fully study the information whether it is possible to connect a laptop to a laptop using any other cable.

Such a connection, indeed, it is possible, it is actively used if it is impossible to provide a wireless connection. It is based on an RJ-45 cable.

One end of the purchased cable is inserted into network card one laptop, and the other end into the network adapter of the second laptop. After that, be sure to make changes to the adapter parameters.

On the first laptop, you should register the IP address 192.168.1.1, the subnet mask will be set automatically, nothing should be changed. On the second laptop, the IP address only slightly changes and can take on this form - 192.168.1.2, the subnet mask will remain unchanged again. Once the corresponding changes take effect, both laptops will be visible on the network, so users can make various actions, exchanging data quickly and comfortably.

It sometimes happens that the first entrance to local laptop fails after connection. However, there is no reason to despair, because everything can be fixed, ensuring successful use of the network in the future. To avoid connection problems, the user should go to the "Network and Control Center" menu and general access", And then go to the" Change advanced sharing settings "section, in which you can set the access settings by connecting the general access.

You may also need to make changes to the guest policy settings. To go to the "Security Settings", where changes will be made directly, type secpol.msc at the command line. In the dialog box that opens, go to the line “ Local Policies", Then in" Security Options ", where you select guest access.

Despite the fact that you have to perform a number of actions and make some changes, all these manipulations are quite simple, accessible and feasible. Each user, if he wants to provide communication between several laptops, can achieve what he wants and become much more knowledgeable in this matter.

How to connect two laptops, wired or wireless (wi-fi) connection

Almost every user had the idea of ​​connecting one computer to another. The reasons are different for everyone: whether it is a game of local network or file transfer (without removable media). Here I will talk about how you can make such a connection so that users have the ability to network merge, unity, if you understand what I mean.

So how do you connect two machines to each other? There are several solutions to this problem:

1). Wired connection... To do this, you need a network card in each laptop (most often it is built-in initially) and a wire, of course.

2). Wireless connection. To do this, you need a Wi-Fi adapter, which, most likely, is also included in the kit of your laptop, if not, then in the form of a PCMCIA card.

Wired connection.

We connect laptops using a network cable " twisted pair". You need: network cards in each laptop, a crimped network cable, which can be purchased at the nearest computer store (which, by the way, I advise you to do, such a cable costs no more than 20 rubles per meter, instead of experiencing extra hemorrhoids with a cable crimp yourself). But the matter, as they say, is the master's, so it's up to you, maybe you already have experience in such a profile. For those who want to directly participate in the whole process of "connection", I will explain how to crimp the cable yourself. You will need: a crimping tool - a crimper, RJ-45 connectors (2 pcs.) And the number of meters of cable you need. Next, I will present a crimp diagram.

Cut off the outer sheath of the twisted pair, carefully! Under it you will see 4 pairs of colored wires. They need to be inserted into one of the connectors according to the diagram shown in the figure and crimped with a crimper.

The cable is ready! It should look like this:

We insert our connectors into the network cards of laptops. On both devices, go to the "Network Connections" -> "Local Area Connections" folder. By right-clicking, go to the properties and in the "Components .." list, select "Internet Protocol (TCP / IP)" and click "Properties". On the first computer, we type the following IP address parameters: 192.168.0.1, and on the second: 192.168.0.2, leave the subnet mask as it is, that is, by default (255.255.255.0). Let's summarize the work done by pinging one laptop with another. This is done by calling the command line (cmd.exe): ping 192.168.0.1. Have you started forwarding packets? You did it.

To make sharing files more convenient, you can assign one workgroup to both laptops. Right-click on "My Computer" -> "Properties" -> "Computer Name" -> "Change". Then we set the same names working group on both machines. Computer to restart. Further, to open access to any folder, right-click on it - "Properties" - "Access" - "Shared" click on the link and confirm. In the future, you can simply check the box "Share this folder".

Connection completed, congratulations!

Do-it-yourself connection via Wi-Fi of computers or laptops.

To make such a connection, you don't need anything other than laptops with Wi-Fi. This connection mode is called Ad-Hoc. It will also be possible to conduct the Internet on both computers, while only one computer will be connected to the Internet. It doesn't matter which laptop you start with, because the settings are pretty much the same. Let's start with the one that has no internet:

1) Open "Network Connection Properties" (via the start menu)

2) Turn on Wi-Fi

3) Now wi-fi setup... In the properties of the network connection

4) Getting started with setting up the IP address. "TCP / IP protocol" and configure it like this: a computer that has Internet access, we assign the following parameters: 192.168.0.1, and the other: 192.168.0.2. The subnet mask is the default on both.

4.1) Default gateway - set the ip address of the first laptop

4.2) DNS server. Its meaning for each laptop is different, find out yours by looking at the provider's parameters

Click "OK".

We configure the setting of a joint Internet connection only on the first laptop.

4.3) Go to the "Advanced" tab in the properties of the network adapter and select "Allow other network users .."

After clicking OK. Windows will warn us that local communication may be lost. network, and that the ip address 192.168.0.1 will be assigned, but we have already set it with you. So don't worry and click OK. (you just might have to turn off your firewall, because it happens that it "does not start" the second computer on the first).

5) Go to the tab " Wireless networks"And click Add.

6) Create a wireless network to connect laptop to laptop. Choose any network name... Below we click on "This is a direct connection ..". We remove the sign from "The network key is provided automatically", after which we enter the key (from 5 to 13 characters) manually and confirm it. ALWAYS REMEMBER YOUR KEY.

7) Setting up the created network automatic connection

In order for your computers to connect to each other as soon as they are in sight, in the "Connection" tab, put the necessary checkbox.

Click OK. We do the same on the second laptop.

When you have correctly configured Wi-Fi, the icon should appear wireless connection on the taskbar on the right.

To check the availability of IP connection, we ping computers. If you have difficulty, try disabling the Firewall.

That's all that was required of you to connect, enjoy your work!

I propose to download a free book as a gift: causes of freezes on a PC, data recovery, computer network through electrical wiring and many other interesting chips.

How to connect laptop to laptop

To simplify the transfer of information, for example, from one laptop to another using a conventional USB flash drive, users often try to connect two laptops to each other via a network or cords. Yes, such options do take place - consider some.

Create a local network using a network cable through a physical connection of devices, provided that the network cards of the built-in plan are present in the laptops. If possible, just in case, buy two adapter adapters.

Disable windows firewall in a standard way through the "Control Panel".

Then go to the "Network Control Center ...". In the settings of the local network, select the properties of the "TCP / IP" protocol. Next, activate "Use the following IP address", where enter the data in the long window. Do similar manipulations with another laptop, but in the "Changes to adapter parameters" window, replace the final address digit with a third-party one, let it be 12 - it's not important.

There is another option - a wireless channel. Add and create a computer-to-computer network in the standard way through the "Network Control Center and ..." and for speed in the search line type "Manage wireless networks", then follow the steps of the wizard.

Make sure that the laptops are not very far from each other, but rather within sight, and have sufficient battery power, only after that do desired settings.

How can two laptops be connected to each other? Where will it be faster? - site of Laptops.No (section Hardware)

In fact, you can transfer data between two computers using any of the computer's peripheral connectors, in particular, a laptop. Each method has its own characteristics, we will consider them in order of decreasing their prevalence and usability:

  • "Normal" network (EtherNet, IEEE 802.3). "Native" way in the sense that the network connector is intended solely for communication with other computers. There is on any modern laptop, an external PCMCIA one can be easily purchased for an ancient device without a built-in network adapter. To connect a laptop directly with another computer, you will need a so-called. crossover cable, which is an ordinary " twisted pair"with different from the usual wiring. Available in any more or less decent computer company. The cable length is up to 100m. After connecting two machines with such a wire, these machines are able to see each other in a network environment. This may require setting up a network connection. The method is supported. the overwhelming number of operating systems, it can be argued that it is platform-independent.The theoretical speed of the most common version of EtherNet is 100 Mbit per second, a gigabit network, as the name suggests, is capable of more; speed is determined by the slowest adapter on the network.
  • IEEE 1394, also known as FireWire and i.Link. Usually a digital video camera or external storage is connected to it, but it can also be a way to connect two computers directly using an appropriate cable. The IEEE 1394 interface is not very common in laptops (external PCMCIA solutions can also be used), but if it is available, pay close attention to it, because the theoretical speed limit for the protocol is 393 Mbit per second, almost 4 times faster than the usual 100- megabit network. Cable length - no more than 4.5 m. Support from outside is required operating system, and this support is not available everywhere. Under WindowsXP, a FireWire connection is established without problems, "pretending" to be a regular EtherNet network.
  • The USB connector also provides the ability to link two computers through itself, but somewhat less convenient. There are two types of USB-Link cables. The first, the simplest, provides only the ability to "see" the contents of another computer connected with such a cable from a simple program that imitates the standard "Windows Explorer" and drag (only from this program) files from one machine to another with the mouse. The second, more expensive, is actually two USB-to-EtherNet controllers, interconnected by a network cable. Of course, in this case, we get a regular network connection, but with the built-in network adapters on both devices being connected, this option appears to be "superfluous": it is easier, faster and cheaper to use a regular network connection (see above). The theoretical maximum of the USB connection speed is 480 Mbit per second, however, the peculiarities of the interface functioning greatly reduce the real speed, which is lower than the speed of IEEE 1394.
  • One of the most convenient in practice options for transferring information from a laptop or to a laptop is, oddly enough, an indirect method using a USB flash drive as an intermediate medium. It would seem that this method has only one drawback in comparison with the direct connection of two computers - additional operations, lower speed, limited storage space. However, the widespread use and ease of use of USB flash drives (always at hand, really working Plug-and-Play) neutralizes all these disadvantages to the level of minor ones.
  • Wireless LAN, aka a wireless network, aka Wi-Fi, aka IEEE 802.11. The modern wireless way of computers (and not only computers) "communicating" with each other. The features are discussed above. The speed in the most common modern version (802.11g) is 54 megabits per second, the communication range is within 30 meters. At the operating system level, it is represented by an EtherNet-type network connection. Supported by the vast majority of modern operating systems.
  • Bluetooth (bluetooth, "blue tooth", IEEE 802.15.1) as a method of communication between two computers is not very good. Not very high speed (no more than 723 kilobits per second in one direction), short range of action (up to 100 meters in the open air, highly dependent on the environment), not the most easy setup, the worst noise and burglar resistance compared to Wi-Fi make the use of bluetooth to transfer data between two computers not very convenient. On the other hand, if you need to connect a laptop with a PDA or mobile phone- bluetooth would be a good option.
  • IrDA, also known as infrared port. Historically the first wireless communication method. On new laptops, it is less and less common (due to competition with other methods), however, on laptops that came out before, it is very common. The speed is low (the fastest options, the so-called Fast Infrared - 4 Mbit per second, "normal" - only 115 kbit per second), the typical communication range is 5-60 cm, while there should be a line of sight between the transceivers ( within about a 30-degree cone) and the absence of direct sunlight. Therefore, it is used only for transferring small amounts of data, and more often not with another computer, but with a mobile phone, for example. Technically, it is a kind of serial interface.
  • LPT-link, aka LapLink cable, aka parallel direct cable connection, aka "direct cable connection through a parallel port", IEEE 1284. systems. Currently dying off due to the withering away of the interface itself; but where the LPT connector is present, it can be used without any problems. The cable length is limited to 2-3 meters. The speed depends significantly on the type of LPT port and can reach 2 megabytes per second, although on older machines without ECP / EPP support, the speed will be an order of magnitude lower.
  • COM-Link, aka serial link, aka Null modem (null modem), aka serial direct cable connection, aka "direct cable connection through a serial port", RS-232. Also one of the most ancient ways. Low speed(usually the upper limit is 115 kilobits per second, and often even less) and the dying off of COM ports were the main reasons for the almost complete disregard of this method in today's practice, although for the sake of sports interest and in some extravagant cases, the method can be applied.
  • Indirect methods using various storage media such as floppy disks, CDs, external hard drives, magneto-optics, etc., have a right to exist, but are either very outdated (floppy disks), or less convenient compared to using a USB flash drive (see above) as an intermediate medium.
  • Exotic options for direct cable communication via modem, encryption via sound card etc. perversions are theoretically feasible, they have no practical meaning.

Connecting two laptops to a network: effective methods

A huge number of external storage devices have been invented to transfer information. But they also have disadvantages: limited volume, low write speed. This can be annoying, especially if you have to transfer files from one laptop to another. Like portable devices, but no use.

However, this is not the case. Having learned how to connect a laptop to a laptop, you can directly transfer large amounts of information without using a recording on external drives.

The connection is usually carried out in two ways, the choice of which depends on both technical capabilities devices, and from the wishes of the user.

Wired connection

If the wireless modules are missing or not working correctly, a perfect connection can be ensured with a dedicated cable.

You will need:

  1. Two laptops with network cards.
  2. Compressed RJ-45 cable.

Note: it is easier to buy a ready-made cable right away - it should be freely sold in any computer store. You can do it yourself, but this requires special knowledge and additional tools, the cost of which significantly exceeds the price of a cable.

The cable connectors are installed in the network card of laptops. Further, all actions are performed simultaneously on two connected devices:

  1. Open the "Network and Sharing Center".
  2. There should be "Local Area Connection" - right-click on it and open "Properties".
  3. The window contains a list of components, among which you must select "Internet Protocol TCP / IP".
  4. The protocol properties will open. Here you need to check "Use the following IP address" and set the parameters.
  5. Write the address 192.168.0.1 to the first laptop, 192.168.0.2 to the second. Do not change the subnet mask value.
  6. Click "OK" - both devices are now available at the IP addresses you assigned.

How to get from one laptop to another

The connection is established, but now you need to learn how to use it. Open up windows explorer and clear the address bar. Write in it the IP address of the second laptop in the format \\ 192.168.0.2. All available folders from another laptop should appear.

Possible problem

Sometimes it happens that when established connection no network access. To open it, re-enter through the control panel in the network management menu and follow the link "Change advanced settings", which is located on the left.

There will be several items, in each of which it is necessary to mark the inclusion of access. Save your changes and try connecting again through Windows Explorer. This time, the connection should go through without any hassle.

Wi-Fi connection

This is the most convenient way connecting two laptops. Considering that in the last decade, without exception, all laptop models are equipped with Wi-Fi modules, such a connection will not require any additional costs. In addition, several computers, smartphones and tablets can be connected to one network at once.

But first, let's figure out how to connect a laptop to a laptop. The first step is to choose one laptop on which the wireless connection will be created. Further:


Then you need to get the IP addresses. To do this, use steps 1 through 4 described for making a cable connection. The only difference is that the IP addresses, as well as the DNS server address, you do not register yourself, but you click "Obtain automatically".

After creating the wireless network and setting up the IP addresses, you can connect between the laptops. To do this, go to "Wireless Networks" through the control panel or by clicking the corresponding icon in the system tray. Here you will see the name of the network you created. Select it, click connect and enter the password that you came up with when creating the connection.

Connection check

To check if the connection is established, you need to start the Windows command line and type in it without quotes "cmd". In the command line, write the address of the other laptop - 192.168.0.2. Press Enter. If the exchange of packets took place, then the connection is configured correctly. If not, try checking from a second laptop, also opening a command prompt and entering the address of the first laptop - 192.168.0.1. The main thing is not to mix up the addresses - otherwise you will "ping" the same computer from which the check is performed, and you will not get the correct result.

Other connection methods

Some users try to use USB cables to connect two laptops. This method cannot be considered successful, since throughput such a connection corresponds to the speed of writing data to a regular USB flash drive.

There are other ways to connect a laptop to a laptop: infrared port, Bluetooth, HDMI, etc. But, firstly, the bandwidth then becomes extremely low, and only a very small amount of information will be transmitted. Secondly, the implementation of the connection in such ways is a much more time-consuming process compared to the ones described above.

The laptop is beautiful in its mobility, and it is in this feature that it differs from stationary computers... You can carry it with you wherever you need it. Sometimes the question arises about whether without a wire, if, for example, you came to visit friends who have their own laptop in order to throw some information on 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 without a wire becomes much more relevant if not network devices, and I do not want to buy them at all for subjective reasons. Here everything is solved quite simply.

The situation with modern devices

For the past decade, all portable devices have come with a built-in Wi-Fi module. Therefore, when deciding how to connect a laptop to a laptop without a wire, there are no special problems. In this case, absolutely no financial costs will be required from you. 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 your wireless network. On it, you should run a command line with administrative rights. Now you need to type certain commands. A password-protected wireless network is being created in the following way... At the command line, you must enter netsh wlan set hostednetwork mode = allow ssid = [network name] key = [password]. You can set the parameters in square brackets as you like.

Settings

When the network is created and already launched, you need to register IP addresses on the devices. This is also quite difficult to do. You must enter the "Network Control Center" - "Changes to 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 then 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. It is required to call its context menu, in which you must select the "Connect" item. The system will issue a request to enter the key and the next request to search for devices is required to give consent. So, if we talk about how to connect a laptop to a laptop without a wire, then 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 the others connected to it will be from the same subnet. Addresses are displayed in the information about network connections... This connection option makes a Wi-Fi router out of a laptop, 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 whether via WiFi. There are other options that are no less relevant.

Create a wired network

So, if you are interested in how to connect a laptop to a laptop via (Windows 7), then this is worth considering. This method is suitable in cases where a module is missing or does not work on one of the devices wireless connection, 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 need to determine how to do the same, only using a twisted pair. Any laptop has a network card. You only need to buy 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 - forward and backward. The first is used to pair a laptop with a router, switch or modem. The crossover is focused on connecting two similar devices to each other. The network cable, crimped according to the second type, differs in that the pairs of wires in it are reversed. It can be purchased at any computer store. One end should be plugged into the NIC of the first laptop, and the other into the other.

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

Alternative options

You can also consider the question of how to connect a laptop to a laptop via USB? It should be noted that this connector allows you to connect two devices directly to each other, but it can hardly be called convenient. There are two types of USB-Link cables. The simplest one only allows you to see the contents of a second computer, which is connected in this way, from a program that simulates a standard system explorer... From this program, you can drag files to your computer using the mouse. The second one is more complex, being actually a pair of USB-to-EtherNet type controllers interconnected by a network cable. In this version, a classic network connection will be obtained, but if there are built-in network adapters on both computers, 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 a regular flash drive. If we talk about how to connect a laptop to a laptop via USB, then it should be noted that the speed of such a connection will be very low, which affects the work in a negative way. The ease of use of a conventional 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 rate is no more than 723 kilobits per second, and the range is rather small. In addition, the network in this case is difficult to configure, it is characterized by poor noise and burglary resistance, which makes it too inconvenient for transferring data between two computers.

Additional ports

LPT-Link provides a direct cable connection through Historically, this method was one of the first, since it does not depend on the installed operating system, so it can be used anywhere. On this moment it dies off 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 an 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 transferring other data. And where there are LPT ports, you can use them without any problems. The length of the cable in this case is limited to three meters, and the speed can reach 2 megabytes per second.

Serial port

The question of how to connect a laptop to a laptop via an HDMI cable can be answered unequivocally: not at all. However, there are several more completely available ways connecting devices to each other. One of them is the serial port. This method can also be attributed to one of the oldest, but from this it has not lost its popularity. This interface is gradually ceasing to be used due to the low data transfer rate, as well as the withering away of the COM port itself, which is simply inconvenient to install on portable devices... But it has a much better chance of being used for a direct connection than HDMI.

Indirect methods

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