How to connect a laptop to a laptop without a cable and through Wi-Fi, HDMI and USB

The notebook is beautiful with its mobility, and it is this feature that differs from stationary computers. It can be carried with you where you need it. Sometimes there is the question of how to connect a laptop to a laptop without a wire, if you, for example, came to visit friends who have their own laptop to throw some information on it. If there is a Wi-Fi router, then the problem disappears very quickly, that is, there is no difficulty with this procedure. However, the question of how to connect a laptop to a laptop without a cable becomes much more urgent if there are no network devices, and you do not want to buy them for subjective reasons. Here everything is solved quite simply.

The situation with modern devices

The last decade, all portable devices come with a built-in Wi-Fi module. Therefore, when solving the problem of how to connect a laptop to a laptop without a wire, there are no special problems. In this case, you do not need absolutely no financial costs. So you can combine several devices into one network, without even resorting to the use of some special software - in Windows 7, 8 and 8.1 already has everything you need.

Networking

First, you need to select one laptop, which will serve as the basis for a wireless network. On it, you should run a command prompt with administrative rights. Now you need to type certain commands. A wireless network with a password is created as follows. At the command prompt, enter netsh wlan set hostednetwork mode = allow ssid = [network name] key = [password]. The parameters indicated in square brackets, you can set such as you want.

Then the created wireless network needs to be started. To do this, enter the command netsh wlan start hostednetwork.

Settings

When the network is created and already started, it is required to register IP addresses on the devices. This is also quite difficult. You must enter the "Network Management Center" - "Adapter Parameter Changes". When you are in the network settings of the device, you need to call the context menu of the wireless network icon. Next, you need to open the "Properties". In the opened window you should find "Internet Protocol version 4 (TCP / IPv4)" and here you need to install checkboxes that allow you to automatically receive addresses.

Communication

After creating and starting a wireless network, you need to go to the "Wireless networks", where the created network will be displayed. You need to bring up its context menu, in which you should select "Connect". The system will prompt you to enter the network security key , and the next device search request is required to agree. So, if you 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, the IP address will be 192.168.173.1, and all the others connected to it, from the same subnet. The addresses are displayed in the information about the network connections. This version of the connection makes a laptop a Wi-Fi router, to which you can connect three or more computers, laptops, tablets, smartphones or other devices. From it you can even distribute the Internet. This is all about the question of how to connect a laptop to a laptop via WiFi. There are other options, no less relevant.

Creating a wired network

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

Cable for connection

The network cable can be compressed in one of two ways - direct and reverse. The first is used to interface the laptop with a router, switch or modem. The crossover is aimed at connecting two similar devices to each other. The network cable, crimped in the second type, differs in that the pairs of wiring in it are interchanged. It can be purchased at any computer store. One end should be connected to the network card of the first laptop, and the other to the other.

After such manipulations, you can further consider the question of how to connect a laptop to a laptop over a local network. To do this, enter the "Network Management Center", where you need to change the adapter settings. You must open the "Properties" of the connection over the local network. Then, in the window that opens, select "Internet Protocol version 4 (TCP / IPv4)". Now you need to set up special subnet addresses and 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 the two devices directly to each other, but it is difficult to call it convenient. There are two types of USB-Link cables. The simplest allows you only to see the contents of the second computer that is connected in this way from a program that mimics a standard system conductor. From this program, you can drag and drop files to your computer using the mouse. The second one is more complicated, representing a pair of USB-to-EtherNet controllers connected to each other by a network cable. In this case, you will get a classic network connection, but if you have built-in network adapters on both computers, this method can be called an unnecessary entity: it's cheaper, easier and much faster to use a traditional network cable, or transfer data using a conventional 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 affects the work in a negative way. Simplicity of use of a usual flash card and its accessibility for purchase simply level out all conveniences of connection of devices directly.

Blutz

Bluetooth is another way to communicate between a pair of devices. This method is difficult to call good, since the data transfer speed is not more than 723 kilobits per second, and the range is quite small. In addition, the network in this case is difficult to configure, it is characterized by poor interference and security, which makes it too uncomfortable to transfer data between two computers.

Additional ports

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

Serial Port

On the question of how to connect a laptop to a laptop via an HDMI cable, you can answer unequivocally: no way. However, there are a few more affordable ways to connect devices to each other. One of them is a serial port. This method can also be attributed to one of the oldest, but from this he has not lost his popularity. This interface gradually ceases to be used due to the low data transfer rate, as well as the dying out of the COM port itself, which is simply inconvenient to install on portable devices. But his chances of using for direct connection are much greater than that of HDMI.

Indirect methods

Knowing which laptops are on the ports, can you ask yourself how to connect a laptop to a laptop via a VGA cable? And then the answer is also unambiguous - it is simply impossible to do this. But if you want to use some complicated method, you can resort to data transfer by means of additional media, for example, disks, flash drives, external hard drives and others.
