Compound of the computer with on Wai Fay. Connecting laptops via Wi-Fi. Possible problems and errors when setting up a home LAN

Connect computers to the network can different ways. It can be a local network via the cable or if there is a router in the room, then computers can be connected through it shared network. If there is no router, you can connect two laptop via Wi-Fi using their wireless adapters. It does not necessarily have access to the Internet.

The need for communication between the devices arose as technology develops, increasing the volume of information, expansion of the uses computer equipment. And if the stationary computer, as a rule, must be bought by the module wireless communicationThe laptops usually have such built-in equipment.

How to associate a wireless connection - in our new article

In laptops, the Wi-Fi module is typically combined with Bluetooth, which also allows you to exchange data between them, only at a lower speed, limited distance and low functionality. Wi-Fi also allows you to configure a full-fledged local wireless network.

Connection of laptops using a router

Through the router, you can connect laptops and stationary computers to the total local networkNo matter how they are connected to the router - via Wi-Fi or network cable. In this case, each device will have its IP address and Internet access, they will also be able to exchange data among themselves. To connect two laptops with a router, do the following:

Default only part of the contents are available. local disk. Full access must be configured manually:

1. Click right-click According to the folder or disk to which you want to access the other laptop.
2. Go to the "Sharing" menu, then "Extended Setup general access", If it is a disc. Or in subparagraph "All users (reading and writing)", if it is a folder.
3. In the case of a disk, select In the "All Users" in the window that opens and check the checkboxes at all points of permissions.

Thus, it was possible to connect separate computers to the local network and now you can move between laptops without restrictions and exchange information. In addition, both are connected to the Internet. With this method, you can connect laptops to each other. Some difficulties may occur, for example, connection errors, password request, etc. Windows is a very capricious safety. Pay attention to the following:

• Parameters of firewall and antivirus - they can block the connection. Disable completely to make sure that they are not the problem.
• Account settings. Try creating on both devices. accounts with the same names and passwords. Do not use an empty password. And you can also create a guest and assign all permissions to it.
• There are cases when problems arise, it would seem, because of such trifles, as a mismatch of dates and time on 2 computers. Check this parameter just in case.

You can check the link using the command line:

• To begin with, in the "Network Map" window, lay the mouse to the laptop icon and the window will be displayed with its IP address.
• Press WINKEY + R, enter the CMD, the command line will appear.
• Type the Ping command and then after the Notebook IP address.
• If the exchange of packages is successful (the message will be displayed in command line), the network works.

If there are no losses - you did everything right

Connection via wireless communication module

If there is no router and you are out of the Wi-Fi zone, it is still possible to connect two laptops to the local network. IN Windows Vista. And above for this there is a special wizard for creating connections. Computers will be born through a built-in wireless module by creating a Wi-Fi connection.

In this case, one laptop must be configured to transmit a signal, and the second will take it. Pay attention to their location, concrete walls and other obstacles create obstacles to broadcasting. To avoid errors, put both computers nearby, make the setting, and then determine the experimental way, how far from each other they can be.

Turn on the Wi-Fi module on both machines and proceed to setting up the first laptop:

1. Go to "Network and Shared Access Management". You can do it by clicking on the icon wireless network From the tray in the lower right corner.
2. Run the new connection setting.
3. In the connection type, select Computer Computer. Next, the system will explain to you that this is a temporary network for data transfer, and if you are already connected to a network, then it may be broken. In addition, the OS will give advice to locate computers within 10 meters. But as stated earlier, it is better to put them closer to customization.
4. Next, by analogy with wi-Fi setup Through the router will be prompted to come up with an SSID, that is, the network name, select the type of encryption and come up with a password. One of the most reliable is the WPA2 protocol, but it is possible and, in general, do not use password protection. If there are no other users in the reach zone, you can connect your laptop without it. If you are in a public place, it is better to take advantage of encryption, otherwise unnecessary can penetrate your data.
5. The end window will open. The network is now saved in the list of possible connections and works while all users are in it.

Before connecting the second laptop, you need to change the data access parameters. By analogy, as a local network was configured through a router, you need to go to the folder parameters or the necessary drives and allow all users to full access. Optionally, of course, you can enable, for example, only viewing files without changing them. You also need to enable network detection.

Now on the second laptop you need to search for Wi-Fi networks, select the desired and click "Connect". You will need to enter a password (the one that we created earlier), then you can enter any files and folders to which access is allowed.

In this way, you can connect as many laptops, optionally one. On the distributing Wi-Fi computer in the tray there will be a message "Waiting for users' connection", which indicates the readiness of the network computer-computer to work.

Using the described simple actions, you can quickly transfer files from one device to another without the use of wires, flash drives, removable disks, even somewhere outside the city outside the Internet zone. If you have a router in the room, then it will be more logical to configure the constant connection of all devices to each other. A full-fledged wireless local network will work on different computers, edit and move documents, view photos and videos, will give many other features and will save from the need for multiple rewriting to removable media.

Computer and laptop - Comfortable items to create a full-fledged local home network. If you have WiFi, you can connect them to each other without using cables.

To connect a laptop to a computer via WiFi, you can via a wifi router, or directly through the built-in WiFi modules. Before you start connecting, you need to make sure that the devices for distribution WiFi. Set up properly, and a computer with a laptop get access to one network.

• IP address (192.168.0.1);

To save the settings you need to click "OK" and exit the menu.

Setting up laptop

To connect a laptop to a computer using WiFi, you need to go to the change in the adapter parameters in the same way as in the main computer. In network parameters you need to enter:

• Internet protocol version 4;
• IP address (192.168.0.2);
• Subnet mask (255.255.255.0).

The remaining change parameters do not require.

Connecting devices

To connect a laptop to a computer, you need to create a connection type "Computer-computer". Next steps:

• In the "Control Panel" select the item "Network and Internet";
• Click "View network status and tasks" and select "Setting up a new connection or network";
• In the connection settings, select the Computer-Computer type and click on the "Next" button twice;

• During the configuration process, select the "Allow access to connection for other devices" checkbox;
• Wait for completing the setting and exit the menu;
• In the control panel "Network and Internet", select "Change Advanced Sharing Options" and click on "Enable Network Circle".

Thus, the computer and laptop will be connected to each other via WiFi.

Connection check

To make sure that the computer and laptop are correctly connected to each other, you must perform the following actions on the laptop:

• Click on the "Start" button and select "Run" item;
• In the string that appears, enter the combination of "CMD" letters and press "ENTER";
• A black window will open where you need to enter ipconfig and click on the input;
• The window will appear where you want to find the "Local Maintenance - Wireless Adapter" item;
• Find the IP address of the laptop;
• Do the same operations in your computer and find its IP address.

If the addresses of the laptop and computer differ on one digit with a difference in one, then devices are connected correctly. You can also execute the command: Ping 192.168.0.1 from a laptop (or Ping 192.168.0.2 from a computer) to check the connection status.

The simplest solution to connect android phone To computer via WiFi - ES Explorer. The app is free and has a clear interface, however most phone owners on android database Restricted by its use only as a file manager. To open the network capabilities of the program, it is necessary:

If the connection is successful, all computer directories will be displayed available for public.

To open files from your phone on a computer via WiFi, it is recommended to use another menu item: "Network -\u003e FTP". Authentication or choice additional settings No need. The application will create an FTP server on your smartphone, will open the required port and provide a ready-made link to connect.

You can view or download files from your phone via WiFi in any browser. Just enter the specified data in its address bar.

If you want to download from viewing files android devices or download folders to it, you can do it through standard applications operating system. To do this, it is enough to enter the address of the server that was provided by the program directly in the "Explorer" string. The directories that are located in the memory of the smartphone will open in the same way as the files with folders on the computer itself.

Important! The most complete use of the smartphone file system when connecting this method can be provided with specialized FTP clients, such as FileZilla or SmartFTP. But even when working through the standard file manager "Explorer" in Windows you can copy files from the phone and on it.

Using Airdroid application

In addition to viewing files on your smartphone, this application provides full phone synchronization with a computer. Connecting to a computer via WiFi is performed in several steps.

It is important to remember that the device on Android and the computer must be connected to the same network. In this case, if a router is used, it can be used for a computer wired connectionAnd the smartphone will be connected via WiFi. If there are difficulties in the synchronization stage, it is possible that the smartphone is connected via the mobile Internet.

After confirmation of the synchronization, connect to the phone. Almost any actions that can be performed, you can do remotely, through a computer and WiFi connection. The interface is made as a separate desktop. In the upper right corner displays information about the device and the number free memory. Just below - the control panel, with which you can send files and folders to the device.

Icons on this desktop work as menu items on the phone. For example, the call log displays the full details of the calls. Synchronization is performed in both directions - with the ability not only to view the records, but also to delete them. Changes will be applied on the phone.

When opening contacts, all numbers are displayed in the smartphone's memory. People from the notebook can be sent SMS or call using the computer.

Of interesting functions Applications can mark the use of the camera on Android. Practical applications This feature is not so much, because the phone is and so is within the distribution of WiFi signal.

In the same time streaming video, the device is connected to the device screen via WiFi. When updating information, a delay may occur, but it is not so big to prevent the work.

Airdroid also opens up full access to file System Smartphone, like ES Explorer. Data on the phone is transmitted via WiFi for both reading and recording mode.

This manual describes the steps to quickly connect to the network of two computers directly (bypassing the access point (wireless hub)) using built-in Wi-Fi wireless interfaces (IEEE802.11).

So, there are two laptops equipped with a built-in or separate adapter with Wi-Fi wireless interface. To connect them to the wireless network, first you need to enable wi-Fi devices On both computers (by default, they are turned off). On the laptop housing, sometimes there is a button or switch, when the light is turned on near the icon similar to (( i. )). On laptops in which Wi-Fi adapter Purchased additionally, there is no such button.

On each laptop, turn on the Wi-Fi device

Now we will deal with the software part setting. This instruction Connection shows the setting of the wireless network under the operating windows system XP; on others operating systems The process will be a little different. Initially, on each computer, the wireless network connection icon is crossed out with a red cross, i.e. Wireless connection is not available .. (Fig.1). The second active icon on this picture is a wired local network, it is in operation, but it does not apply to this topic, so it is no longer paying attention.

Fig.1 Press on a crossed out icon owned by a wireless network

Select one of the computers to configure (second to leave). Click on the transmitted icon belonging to the wireless network interface, and thereby call the following window (Fig.2):

Fig.2 At the first stage of the wireless network of available networks available

In the window that appears (Fig. 2), I have no inspected networks available. Theoretically in the list of networks can already be some name, provided that the configured wireless network is already working near you (within 100m), but here you will not complicate, considering that in practice wireless networks are rather an exception than the norm, and The purpose of this article is a quick practical manual on how to achieve a connection of two computers without wires, without going into details .. Therefore, we click on "additionally .." (Fig.2) and go to the next window (Fig. 3)

Fig.3 At the first stage of creating a wireless network there is no available networks

Here, too, all nine clean, press "add .." - we will create the first network ..

Fig.4 Creation new network Direct connection

In a new window (Fig.4) we enter the name of the future network (I invented the "new") and two important points: remove a tick near "data encryption (WEP)"I. we note that "this is a direct connection of the computer-computer...: Click "OK" ..

Fig.5

An old window appeared with the name of the newly created network .. (Fig. 5) Click "OK" ..

Fig.6 From the wireless network icon disappeared the cross. This computer is included in the NEW network.

As a result, a red cross disappeared from the wireless network icon, i.e. The created network under the name "NEW" already lives. True, only one computer is included in this network, but it is already available for another machine .. We will not get ahead and completed the settings on the first laptop. Clicking on the wireless icon we will get a window with information about the current state. wireless connection (Fig. 7).

Fig.7 Condition of wireless connection. While waiting.

There is no signal - so it should be (not yet to be worried about anyone), go further - press "Properties" to get into the settings of the network wireless interface (Fig. 8) where we configure TCP / IP protocol as for a standard connection.

Fig.8.

So click on the line "Internet protocol (TCP / IP)". I recommend using the first computer as an IP address to use traditional numbers for this type (Fig. 9):

Fig.9 IP addresses on the first computer.

On this settings on the first computer can be considered completed. The only to check that everything was done without errors I recommend to execute the Ping command with the above IP address. To do it, click Start-Run and appeared to enter the desired string (Fig.10)

Fig.10 To check, use the Ping command.

A successful response to this command will be the appearance of the next window of approximately such a content (Fig. 11)

Fig.11 The result of executing the Ping command with the address of the first computer.

Everything. Go to the second computer. Press the icon belonging to the wireless network connection (just like on the first computer (Fig. 1)). The window will appear (Fig.12) in which there must be a network name that we have already created on the first computer and which is now available for connecting to the second computer ..

Fig.12 On the second computer, the NEW network is available on the first laptop.

If the list of names is empty ..., in addition to the reasons for the inaccurate execution of the above (most likely the Wi-Fi switch is not translated into the on position), you may have done everything so quickly that it has not yet passed 20 seconds after setting up the first computer. Usually there is a slight delay in detection available network. But if after a successful executed Ping command (Fig.11) passed a few minutes, and on the second wi-Fi laptop The driver is turned on and the driver is installed, and the list is empty ... I can assume that in one of the computers a weak antenna. To check, bring laptops to each other as close as possible ..
However, if you were attentive, and equipment is obviously regular, then at a distance of up to 100 m with a guarantee of 99.9% after a minute after setting up the first computer on the second will be available. needled networkAnd this suggests that we are already very close to success, and two computers will certainly be connected without wires :).
Click the "Advanced" button (Fig.12) and go to the next window (Fig.13)

Fig.13 To connect to the new NEW network, click the "Set" button.

Here we click "set up" and go to the window (Fig.14).

Fig.14

Nothing to correct here. But check the matching of your window with this. I will specify that checkboxes in "data encryption (WEP)" should not be. (If it is - most likely you forgot to turn off encryption at the first laptop setting step (Fig. 4) ..)
Click "OK" and proceed further (Fig.15)

Fig.15

Network "New" hit the list of preferred networks. To check, click "Properties" - the properties window must match Fig.16.

Fig.16.

Everything. Connecting the second computer to the network "NEW" took place. We leave all the windows (click "OK"). On the wireless icon network connection A briefly will appear about the success of the connection (Fig. 17), now it is active (without a red cross) ..

Fig.17 From the wireless network icon disappeared the cross. The second laptop is included in the NEW network.

On the wireless network connection icon, the connection successful will appear briefly (Fig. 17), now it is active (without a red cross). When you hover the cursor, information about the signal level and the speed of the connection appears on the icon (Fig.18).

Fig.18.

When you click on the icon, we get a window with more complete connection information (Fig. 19).

Fig.19

Connection speed 11.0EBIT / C - Maximum for Wi-Fi standard (802.11b) and indicates that everything is done correctly .. It remains only to configure the TCP / IP protocol on which data will be exchanged with the first computer. To do this, click "Properties" and by the exact analogy with the first computer (Fig. 8 and Fig. 9), we set the IP address and the subnet mask for the second computer (the IP address of the second must differ in the last digit, for example, 192.168.0.2, and the subnet mask should be identical). Checking Ping specified addresses from the second computer (both IP addresses must give a response). Network for data exchange is ready. We organize network access (in properties hard disk or folder). And that's all!

With the need to connect to Wi Fi modern man It faces everywhere: wireless networks are much more practical and more convenient for their cable "fellow".

That's just like wifi-privileges basically "enjoy" all sorts of mobile gadgets: phones, tablets, smartphones and most modern laptops. Accordingly, the question arises: what "classic" personal computer is worse? After all, it is much more convenient to work on a landline computer, and the connection cable Internet Often delivers a lot of trouble.

And in this article we will analyze how to connect a stationary computer to WiFi, and what needs to be done to "catch" the invisible Wai Fi.

By the way, the age of the device is not directly related to the creation of a wireless network, and you can even connect WiFi to a relatively old computer.

Is it possible to connect a regular computer to WiFi?

Some difficulties with the connection of Wi-Fi on personal Computer It is not related to the "prejudice" of developers or unsuccessful complete deprivation by the fate of this device.

The fact is that mobile devices And modern laptops are originally equipped with a built-in Wi-Fi adapter for connecting to a wireless network (which is missing on a stationary computer). However, such devices are mostly intended for short-term access to the network, and have a rather poor set of functionality.

While the stationary computer is designed for long work both with a serious offline software and with any global resources. information network. Accordingly, the connection to all peripheral devices and external networks (Internet, power supply, etc.) here is carried out by a more reliable cable method.

The cable connection to the Internet for a stationary computer is more stable than the wireless Wi Fi connection. So, for WiFi Connection Reliability and speed of the network directly depend on the number active connections, Channel load, room architecture and many other third-party factors.

Therefore, to solve connect home computer To WiFi exclusively from aesthetic considerations - still not worth it. "Standard" cable connection is more reliable, more efficient ( not), and the damage to the health of the Internet user is much smaller.

However, if a strict connection with the Internet source for some reason is not available, then you can connect Wi-Fi on the home computer in a matter of minutes.

How to connect a home computer to wifi?

To connect WiFi to a stationary PC, first of all, you need to purchase a special removable Wi-Fi adapter - a miniature antenna that will "catch" the Internet signal transmitted by the router and return the data processed by the user.

The most popular I. inexpensive solution Here will be the choice for a computer of a removable USB adapter.

In order not to get a "cat in a bag", buy a device better at well-known and proven manufacturers: TP-Link, D-Link, etc.

If you have purchased an adapter from the official distributor, then the device comes with the device special program To install drivers.

How to install Wi-Fi on a Windows 7 computer?

1. Connect your adapter to any USB connector on your computer.

2. Install the disk into the drive, run the auto-tuning utility and press the "Next" button at the request of the program.

3. After installing the driver in the Network Management Center folder for Windows 7 (or " Network connections»For Windows XP) you will see a new shortcut (in addition to the usual" LAN connection "). In the title of the label there will be a brand of manufacturer of your adapter.

4. Now you can connect your stationary computer to WiFi. To do this, click on the label right-click -\u003e "Connection" -\u003e Select Your Name Wi-Fi network And enter the password.

How to configure Wi-Fi if there is no installation disk?

In addition to the "classic" acquisition of a new licensed adapter, there are cases when Wi-Fi on the computer needed the user "here and now", and he lent from acquaintances / acquired an old used WiFi adapter.

Driver disc on such an adapter, of course, has long been lost.

In such a situation, you need to download the archive with the driver from the Internet.

"But there is no internet!" - You say - "What to do?"

Here for connecting desktop computer To WiFi follows:

1.

Connect the customizable computer with the router using a cable (if there is such an opportunity).

Go to the official website of the manufacturer of this adapter (or profile resource ddriver.ru), to find the driver you need called the USB-Wi-Fi adapter and download software on your computer.

If the cable connection to the router is not possible, download the driver you need to any computer connected to the Internet, and using removable media (Flashki) Copy the archive to your wired computer.

2. Next with the right mouse button once, click on the "My Computer" label below - "Management" and select "Device Manager" here. In chapter " Network adapters»Find the name of our USB adapter, click on it right mouse button and select the" Update Driver "menu item. Specify the folder to which the archive was copied with the necessary driversand click "OK".

3. Upon completion of the installation, you can connect your stationary computer to WiFi. To do this in "Network connections":

Select a new label;

Click on it right mouse button;

Select the "Connection" menu item;

Select the name of your Wi-Fi network (which you specified in the SSID when configuring the router);

Enter the password and you can use the Internet.
