Connecting laptop to laptop with cable. How to connect a laptop (computer) to the Internet via Wi-Fi? Wi-Fi connection problems

Youtube

Today I will talk about how to connect a laptop to a laptop yourself, without waiting for the help of an IT specialist. Since there are only two types of connections for any computer - wired and wireless - we will practice connecting to another laptop via a network cable and via Wi-Fi. In the first case, both computers must have network cards, and in the second you will need any Wi-Fi adapter.

How to connect a laptop to a laptop: wired connection of laptops

You will definitely need a special power cord - a patch cord. Just like other types of network cables, it is a twisted pair with RJ-45 connectors at both ends. The peculiarity of the patch cord is the crossing of cores, which is why computer scientists call it “cross”. Those who have a laptop on their own are strongly recommended to buy such a cable at the nearest service center or any computer store. Others can try to connect it themselves. On one side of the cable, the order of the wires should look like this: white-yellow/yellow/white-lime/blue/white-blue/lime/white-mustard/mustard. At the other end of the twisted pair, the wire colors are different: white-lime/lime/white-yellow/blue/white-blue/yellow/white-mustard/mustard.

The ends of the cable are plugged into the network cards of laptops. Then you need to go to “Network Connections” and get to “Connection via local network" In the network connection settings, you need to select the network connection protocol - TCP/IP. IP addresses are specified in the protocol settings on each machine; the subnet mask remains standard. In the search window you need to enter the characters “cmd”, and in the black window - the command “ping” and the known IP address of the second laptop. If you followed the instructions carefully and crimped correctly twisted pair, the packet data exchange will be visible in the window. This means that the connection has been established properly.

Wireless connection of laptops (Wi-Fi adapter)

It is also easy to connect machines via Wi-Fi, setting the point-to-point mode. You need to enable the adapter on both computers by clicking the toggle switch or doing it programmatically. After that, click on “Start”, go to “Control Panel”, and from there go to the “Network and Internet” category to adjust the network connection settings. In this section you need to deal with the TCP/IP protocol as described in wired connection. If one of the laptops is supposed to be connected to the Internet, you need to register the IP address 192.168.0.1. If the second laptop starts accessing the network via Wi-Fi, you will have to adjust two more parameters: the main gateway (register the IP address of the first machine - 192.168.0.1) and the DNS server used - the address given by the provider.

On the laptop that has connected to the network, you need to go to the network adapter settings and in the “Advanced” tab, check the “Direct connection” box and uncheck the box for automatically providing the network key. Next, enter the network key, which will be used when connecting a second laptop. It is important that it is configured automatic connection to the network. In order for two machines to safely connect to each other on the network, as soon as they “find” each other, you need to go to the “Connection” tab and check the appropriate box.

There are other ways to connect laptops to a network - for example, using USB cords or an infrared port on older models, but the reliability of such a connection is debatable, so we will not closely consider these options.

To transfer a large amount of data from desktop computer for a laptop, no need to buy external hard drive or an expensive flash drive for a whole terabyte.

But connecting a laptop to a computer via USB like a tablet or smartphone (which I wrote about in) will also not work. A network needs to be installed and configured between devices. PCs and laptops combined into one home network open up a lot of opportunities for group use of devices - this network mode games, this is multi-user work with programs, it is fast and convenient exchange files. At the same time, unlike connecting mobile devices, such a connection is equally functional both with a wired and wireless connection.

Connecting a laptop via a network cable

The easiest way to combine a PC and laptop into one single network– this is a connection via a network port. The RJ 45 LAN port is available in all PCs and laptops - both old and new models. Devices connect network cable « twisted pair", it can be purchased (already crimped) at any store computer equipment or from your provider. Don’t make a mistake with the footage - it’s better to buy more meters of cable rather than embarrass yourself later.
Connect the cable to network ports PC and laptop, then proceed with the standard network settings using Windows. To transfer files over the network, open network sharing to those folders that will be accessible to both one and the other device.

Wireless connection using Wi-Fi

To establish a direct connection between a PC and a laptop via Wi-Fi, naturally, these modules must be present on both devices. This is available in almost all modern laptops, all-in-one PCs, as well as in “advanced” assemblies. system unit. However, even if your PC does not have built-in Wi-Fi, you can always purchase it separately in the form of a USB or PCI adapter.
At wireless connection one of the devices should act as an access point, and the other will connect to this point. This type of connection is called Ad Hoc and is characterized by the fact that wireless connection installs without the help of a router.
Activate Wi-Fi modules on PC and laptop, then regular means Windows configure wireless network on both devices.

Often laptop users need to connect two devices. Depending on how well you understand this type of technique, there are several ways. Before connecting your laptop to your laptop, be sure to check out all the options to choose the one that suits you best.

Wi-Fi as a synchronization method

Perhaps the simplest and in an accessible way How to connect two laptops is connecting by. No special knowledge is required here, you just need to follow the simple instructions step by step, even if you understand absolutely nothing about this synchronization method. 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. Configure PC No. 1 as for normal connection to Wi-Fi. Turn on the router, open “Network Connections” in your laptop, create a new wireless network if there is none. At all connection steps, agree with what the system offers. Attention: if you want to access the Internet on device No. 2, then on last step Check the box next to “Allow other users to access the network.”

2. On device No. 2, configure 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 the same as device No. 1 (you can view it in the same tabs on the configured laptop). Whatever the system tells you, choose these values, agree with everything.

3. On device No. 1, create another wireless connection with any name (this will be the 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 you don’t forget. Before connecting a laptop to a laptop, check the “Direct connection” box, and also disable automatic key entry (it’s easier to do this manually).

4. On device No. 2, repeat step three so that laptops have one shared network where they can see each other. This is where the created key will be needed to connect them without any wires.

5. Test the visibility of devices to each other. It's easy: in active Wi-Fi zone on each of the laptops a window should appear notifying about the presence home network(current connections).

TO possible problems The following can be attributed: it blocks a network that is foreign to it (the one you created), and therefore does not allow devices to synchronize. Just disable it on both laptops.

in a couple of clicks

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

It doesn’t matter what company they are, what operating system(if it's one Windows family, Certainly). This method is ideal for those who need to frequently and frequently transfer information (of any format) from one device to another. Before connecting 2 laptops, distribute the information into folders on them. This will significantly reduce your time in the future.

Step 1: Create a HomeGroup

On any laptop, go to the “Control Center” folder. For comfort main laptop will be number 1. Click on the “Network and Internet” tab, then “Homegroup”. If you have not previously created it (for any purpose), then this needs to be done. Click on the “Create Home Group” button.

Step 2: Define Folders

Windows will offer you several folders to choose from that will be visible to your HomeGroup. Check the boxes where you need them. If your personal devices are connected, then there is nothing wrong with setting access everywhere. In any case, you can then add folders at your discretion for general viewing in the home group.

Step 3: Create a Password

For security purposes, the system will give you a password, which you can then use to connect a second device to the home group. Write it down. Your group is ready immediately after clicking “OK”.

Step 4: Join a HomeGroup

Before you connect your laptop to your laptop, make sure they are (it doesn't matter how). Without this, it is impossible to create an environment for devices to “communicate.” On device No. 2, go to “ Home group"Similar to step 1, click "Join". Enter your password and allow access to the necessary folders, click “Ok”. After this, you can safely send files from one device to another, but to strictly specified locations on your hard drive.

Of course, this is far from the only ways how to connect a laptop to a laptop, but the simplest and most affordable, without extra costs. As, for example, in the case of a cable, which you need not only to buy, but also to choose the appropriate one, otherwise there is a risk of ruining both devices.

Connecting two computers using a cable may be necessary in the most different situations. Using a crossover cable you can working connection between two computers, between two laptops or between a laptop and a computer. In particular, such a connection can be useful for those users who want to transfer large files from one machine to another (for example, a collection of films or music albums).

Using a cable is ideal if you want to connect two computers but do not have special network equipment at hand. If one of the machines has two network cards installed, then you can easily configure Internet access on this machine and on the other. If only one network card is installed on the computers, this will not work.

We will analyze in detail two connection options. In the first case, we will talk about the features of setting up a connection when only one network card is installed on each computer. In the second case, the settings will imply the presence of two network cards on one of the computers (both a regular PC with two cards and a laptop with one regular network adapter and the second wireless).

What is needed to connect two computers

For cable connection computers we do not need any special network hardware. You can carry out all operations yourself using a minimal set of components.

We will need:

Actually two computers
Cross cable
Perseverance and a little patience

A crossover cable can be easily purchased at any electronics store or radio market. Also, if you wish, you can prepare such a cable yourself, but this will undoubtedly be more difficult and longer. The crossover cable pinout is shown below.

The finished cable that will be used to connect computers is shown below.

This option is used most often, since few computers (especially PCs) have two network cards installed. In most cases home computer equipped with one network card. With this type of connection, both machines will not have access to the Internet. General scheme connection is shown in the photo below.

After a physical cable connection between two computers, you need to carry out simple network settings. We will analyze the entire setup process in detail so that you do not have any questions.

To get started, go to Network and Sharing Center and shared access and follow the link “Change adapter settings”.

After that, double-click on the cable network connection.

Click on “Properties”.

We install selectors opposite the manual setting of network parameters and enter the values there as in the photo below.

Click “Ok” and “Apply”. On the second computer, the sequence of actions is similar, but in the IP address field we enter the value “192.168.0.2”. After these simple settings, a working connection will be established between the two computers.

To check the functionality of the created network on a second PC, press the key combination “Win + R” and enter the command “cmd”.

In the window that appears, enter the command “ping 192.168.0.1”. In response, a message should appear indicating the successful transmission of packets.

The same can be done on the first computer, just use the command “ping 192.168.0.2”. If you are unable to ping the network, it means you did something wrong or the connection is blocked by an antivirus or firewall.

Now let’s take a closer look at the option of how to connect two computers with a cable so that each computer can access the Internet. To do this, one of the machines must have two network cards installed: one for connecting to another computer, the second for connecting the provider’s cable. The general connection diagram is shown in the photo below.

The network settings are the same as those we looked at in the first method, with the exception of one point. In addition to the IP address and mask, you will also need to set the gateway.

On a computer with two network cards needs to be configured network access to the Internet, so that on the first computer you can freely use the Internet. To do this, on a computer with the address 192.168.0.1, go to the “Access” tab and check the box next to the corresponding inscription. After this, both computers will be able to access the Internet.

conclusions

We found out how you can connect two computers using a crossover cable and how to correct setting connections for normal operation networks. We really hope that this information will help you solve the problem of connecting two computers quickly and efficiently.

Hi all! After reading the article below, you will learn how to connect a laptop to the Internet via wifi. Mobile computer device considered a laptop. By purchasing it, the user gets the opportunity to use it absolutely anywhere. It is not very favorable to connect a laptop to global network via cable. Having thus connected to the Internet, the laptop turns into a simple home PC. That is why I decided to take on this topic, since it is currently very relevant.

The first thing you need to do is find the “wifi” icon. This sign may look different for everyone, it will depend on whether the laptop is connected to Wi-Fi or not connected.

This icon serves as an assistant for various operations.
So, after this, a window will appear in which all available network points will be displayed. Select the necessary network and click "Connect".

Then there are 2 options. If the network is not password protected, the connection will occur immediately. If the network is password protected, a window will appear where you will need to fill out a line.

After entering the password data, the Internet should work.

If you have any problems, then read on.

I can't find the icon I need

If you have a problem such as the absence of the “wifi” icon on the taskbar, then your Wi-Fi module is disabled. To enable it you must do the following:

Log in to the “Control Panel”;
Go to “Network and Internet”;
Then visit the Network and Sharing Center;
Select "Change adapter settings";
Find "Wireless" network connection» and connect it via the context menu.

Sometimes a similar issue arises due to the lack of drivers. In this case, they will simply need to be installed.

The icon is marked with a red cross

This is another one standard problem. In this case, the user will not be able to connect.

Usually, this means that such a module is disabled through the “Mobility Center” or through certain buttons on the body of the laptop itself.

To solve the problem you need:

indicate battery icon right click mice;
select “Windows Mobility Center”;

Specify “Enable wireless communication.

If such a network is already turned on at this point, it means that the module is turned off through buttons or key combinations.

Conclusion

Thus, now you know how to connect a laptop to the Internet via wifi. I hope that my information will be useful to you. Thank you for your attention, good luck everyone!
