If you have several laptops at home or at work and you need Internet access on each laptop.

And also if you need to share folders and files between laptops, then you need to create a local area network with Internet access.

With development wireless technologies the most convenient option is to create a local wireless network via Wi-Fi. In this case, all laptops must be equipped wireless Wi-Fi- adapters.

local wireless wifi network can be created in two ways:

1. Infrastructure mode. In this mode, laptops access the Internet and exchange information with each other through a special device - an access point (wireless router).

2. Ad-Hoc mode. In this mode, laptops communicate directly with each other and Internet access is carried out in most cases through the main computer (a computer or laptop connected to the Internet and acting as an Internet gateway).

Most best option this is the networking of laptops using the infrastructure mode. To do this, you will need to purchase a wireless router. But if buying a router is not yet in your plans, then you can create a Wi-Fi network directly between laptops (Ad-Hoc). This article will discuss how to do this. To make it easier for you to navigate Wi-Fi setup networks I will explain the following definitions:

Host network computer - a computer or laptop connected to the Internet and acting as an Internet gateway. A Wi-Fi connection will be created on this computer.

Other computers networks - computers or laptops connected to a Wi-Fi network created on the main computer and accessing the Internet through this computer.

Setting up a network host

Turn on the Wi-Fi adapter. In the notification area (tray), click the wireless network connection icon.

Note: if this icon is not displayed, then it is probably hidden and you need to click on the arrow to see it. If this icon is not in the notification area, then your Wi-Fi adapter may have been turned off by software and to turn it on you need to go: Start - Control Panel - Network connections- double-click on the Wi-Fi wireless connection icon. It may also happen that you do not have a driver for the Wi-Fi adapter installed or this adapter does not exist at all.

On the Wireless Networks tab, click Add...

In the Network name (SSID): field, enter an arbitrary network name.

In the Authentication: field, select Open.

In the Data Encryption: field, select WEP.

In the Network Key: field, enter the network password. The password must be 5 or 13 characters long. The more signs the better. To create a password, it is better to use a password generator.

In the Confirm key: field, enter password confirmation.

Check the box This is a direct computer-to-computer connection; access points are not used.

Go to the Connection tab and check the box Connect if the network is in range. Click OK.

Check the box next to Ignore Disabled network hardware. Click "Next.

Check the box This computer has a direct connection to the Internet. Other computers on the network connect to the Internet through this computer. Click "Next.

Select an Internet connection from the list. Click "Next.

Check the box next to your wireless adapter. Click Next.

In the Description: field, enter a description of the computer, such as Vasily's Computer.

In the Computer name: field, enter a computer name. The computer name must be unique. You cannot specify a computer name that is already in use on the network. Click "Next.

In the Workgroup: field, enter a name working group. The workgroup name must be the same on all computers on the network. Click "Next.

By default in all Windows versions XP excluding Windows XP Home Edition and in all versions of Windows 7, vista name working group - WORKGROUP.

If you will be using folder and file sharing, check Turn on file and printer sharing. Click Next.

Wait a little...

Check the box Just complete the wizard, there is no need to run it on other computers. Click "Next.

Click Finish.

Network host setup is complete.

Setting up other computers on the network

Turn on your wireless adapter. Click Start - then right-click My Computer and select Properties. Click the Computer Name tab.

In the Description: field, enter a description of the computer, for example, Fedor's computer. Click the Edit... button

In the Computer name: field, enter a computer name. The computer name must be unique. You cannot specify a computer name that is already in use on the network.

In the Workgroup: field, enter the name of the workgroup. The workgroup name must be the same on all computers on the network. Click OK. Next, a reboot is required. If you don't want to change the computer name and workgroup name, just click Cancel.

Note: By default, in all versions of Windows XP except Windows XP Home Edition and in all versions of Windows 7, Vista, the workgroup name is WORKGROUP.

Click on the wireless network connection icon.

Note: If this icon is not displayed, then it is probably hidden and you need to click on the arrow to see it. If this icon is not in the notification area, then your Wi-Fi adapter may have been turned off by software and to turn it on you need to go to Start - Control Panel - Network Connections and double-click on the Wi-Fi wireless connection icon. It may also happen that you do not have a driver installed on your Wi-Fi adapter or this adapter does not exist at all.

Click the General tab. Double click on the Internet Protocol (TCP/IP) line.

Check the box Use the following IP address:

In field IP address: Assign an IP address to the wireless adapter. The IP address must be unique and from the same subnet as the host computer's wireless adapter IP address. The network should not have devices with the same IP. Since the Wi-Fi wireless adapter is assigned an IP address of 192.168.0.1 on the host computer, the IP addresses on other computers on the network should be: 192.168.0.2, 192.168.0.3, etc.

Important: If your network host is running an operating system Windows systems 7, then its wireless adapter is assigned the IP address 192.168.137.1, which means that other computers on the network need to specify IP addresses: 192.168.137.2, 192.168.137.3, etc.

In the Subnet mask: field, enter the value 255.255.255.0.

In the Default gateway: field, enter the IP address of the host computer - 192.168.0.1.

Important: If your network host is running under Windows control 7, then the IP address of the main gateway must be specified 192.168.137.1

In the Preferred DNS Server: field, enter the IP address of the provider's preferred DNS server.

In the Alternative DNS server: field, enter the IP address alternative DNS provider server.

Addresses DNS servers can be obtained from the provider.

Click OK.

Click the wireless connection icon.

Double click on your wireless network.

Enter your password and click the Connect button.

All. We set up a Wi-Fi computer-to-computer wireless network in Windows XP.

Hello to all blog readers. Heading above, this topic is for today, as many more people use this system, and I think it will be useful to many users.
Wireless technologies have firmly entered our lives with the acquisition of smartphones, tablets, laptops. Majority modern devices already included established WiFi module, this applies to most laptops, netbooks, tablets and smartphones.
However, if you have an old computer, then you can also connect it to Wi-Fi. There is a special device for it: WiFi adapter. And of course on your PC
there must be at least one USB slot. Every gadget owner sooner or later faces the question of how to set up WI - FI in Windows XP.

Equipment for Wi-Fi

To connect the Internet with the subsequent organization of a Wi-Fi network, you will need
router or router. It should be noted that router and router- This two
names of the same device. It is used only if
There is a ready connection to the Internet via a modem.
Modem and router- two different devices performing various functions.
Modem designed to convert a signal that is transmitted via wired or
3G network, in an easy-to-understand system.
router designed to transmit the decrypted signal to other network members
without conversion. Thus, without modem network signal operating system
Windows XP device will not be recognized.
Now the line between the modem and the router is gradually being erased. Many manufacturers
both devices are combined in one housing. This device allows you to create
wired local network for 4-5 computers (depending on the number of ports in the model) and organize a wireless connection in parallel.
When choosing a router model, first of all pay attention to way connection to
the Internet.

There are three types of WAN - ports for connecting to the Internet:

1. ADSL designed for internet connection telephone line

2.USB 3G used to connect USB modem

3.Ethernet designed to connect network cable

If you plan to connect third-party devices to your wireless network,
You must select a machine that supports data encryption. In this case, in
settings modem (router) all permitted IP addresses to connect.

Setting up a router

Configuring the router and the view of the WEB - interface various models can among themselves
differ. The principle of setting and the sequence of actions is preserved.
The router must first be connected to the Internet through the port
WAN and whether USB 3G and to the computer through the port lan.

How to set up a network on Windows XP:

1. We go to Start → Control Panel → Network Connections →
Connection via local network.

2. In the window that appears, select " Properties»,

then right click on " Internet Protocol TCP/IP» and press « Properties».

3. In the window that appears, check the box " Get an IP address automatically" And
"Obtain DNS server address automatically" and confirm OK.

If Wi-Fi does not work on Windows XP

Important! Windows with different pack service support different security protocols!
Windows XP SP2 does not support security protocol WPA2! Only WPA1.
Thus, if there is a problem when connecting, you need to look version
windows xp, and security protocol The that the access point uses.

If your computer does not have " Wireless Network Connection" reason may
be in the following:
1. You Windows XP SP2, and the access point is set to the security protocol WPA2. Need or
install SP3 or reconfigure the access point to WPA.
2. On your computer at all NoWiFi adapter. You can find out through Dispatcher
devices. Wireless must be in the list of devices LAN card.
3. On your computer WiFi adapter is, but he disabled. For example, on many
laptops have a shutdown button WiFi adapter. It can be a separate button or
one of the buttons F in combination with a button fn. If WiFi adapter is built into the motherboard
fee, it may be disabled in BIOS.
4. Adapter present but not installed drivers on it, in which case it will be in the list
devices as unknown device.
If " Wireless network connection" yes, it shows network list,
but can't connect To desired network, then the reason could be that:
A. Too much weak signal between your adapter and access point.
Long distance, thick walls, etc. Moreover, the signal strength of the access point
might be decent, but your adapter's signal does not "come" to the point
access. Because the adapter signal is generally weaker than the signal
access points. Especially if the adapter is built-in, such as in a laptop.
b. you entered wrong password. This is especially relevant for Windows XP That's why,
what is there it is forbidden see password characters.
V. If the connection to the access point is established, but the Internet is not working, then
reasons may be:
- WiFi router(access point) not connected to the Internet. For example, a technical failure
provider, or lack of funds in your account with the provider.
- The technical error in the work of servers DNS at the provider.

5. If the Internet does not appear, the addresses are registered manually, for this they are rearranged
tick on the line " Use the following address".

Required addresses IP and DNS servers You can check with your provider's support team.
6 . To make settings router necessary when enabled device in browser
dial IP - address of the router. IP address router is indicated on the rear panel.
7. Further in the appeared window enter login and password. If the device was purchased
directly from the provider, the login and password are registered in contract.
If the router was purchased independently, the login and password are indicated
by the manufacturer in the documents, not all devices have a login and password
on the sticker. Factory login and password recommended change, to avoid
unauthorized access to network settings.
8 . The main menu opens: WEB interface models.

For the convenience of the user, some models provide for changing the language in
upper right corner into Russian. Next, you need to configure the settings PPPoE,

they are configured once during the initial setup of the device

How to configure a router in Windows XP with an example

In the main menu on top panel buttons are selected SETUP" And " INTERNET SETUP".
On the updated page, click " Manual Connection Setup".

Write in a new window necessary settings networks:

1 .My internet connection is– select protocol PPPoE(Username/password);
2. Dynamic PPPoE– select from the list;
3 .user name–login for Internet access specified in treaty provider
4.Password– password for Internet access specified in the provider agreement;
5 . service name- Name provider;
6.RetypePassword- again password for Internet access.

The settings must be saved using the " SAVE SETTINGS», then reboot
router using the button REBOOT” for the entered parameters to take effect.
In some cases, the protocol is used by the provider DHCP instead of PPPoE, That's why
the protocol type must be specified with the provider.

For settings Wi-Fi n you need to select " SYSTEM» → « WIRELESS SETUP»,
select at the bottom of the window "MANUAL WIRELESS CONNECTION SETUP».
In the window that appears, select or enter the following parameters:

1. Wi-Fi protected setup (WCN2.0) – disable
2 .Enable Wireless - enable
3. Wireless Network Name (SSID)) is a fictional name for the wireless network
For example Wi-Fi_HOME
4. Enable Auto Channel Selection - enable
5. WMM Enable - disable
6. Enable Hidden Wireless - disable
7. Security Mode - select WPA / WPA2, which will allow encryption of the network;
8. Cipher type - TKIP
9.PSK/EAP-PSK
10 Network key- invented key to access the wireless network (minimum 8
symbols English letters and numbers).
Save the settings using the " SAVE SETTINGS», then reload
router button REBOOT for the settings to take effect.

Connecting devices via Wi-Fi

When connecting devices via a wireless network uncomfortable enter every time
login and password if the same gadgets are used to connect.
In order to connect devices in Windows XP performed automatically
but at the same time for third-party users WiFi access has been denied, should be in the router settings limit access By MAC addresses for these devices in this way:

1. Enter settings router via browser, as previously described.
2. Enter menu " Advanced", in it select the item MAC Filter».
3. A table will open in which you need to enter all available for connection.
4. Save the data and reboot the device.

How to determine MAC addresses connected devices?
For PC with OS Windows XP you need to call the command line, register in the menu
Start - Run: command - cmd.

In the emerging command line enter command
ipconfig and press Enter.

In line IP address:- desired MAC address devices.

How to distribute Wi-Fi using a computer to other devices?

Previously, it was considered how to set up a router and connect to Wi-Fi on a PC with OS Windows XP. Can arrange Wi-Fi network by using PC, making it a dispenser.
More often this way network organizations are used when it is necessary to restrict access to the Internet to a second device. If the distributor PC turned off, network transmission
not produced. Such a transmission has a limited range, is not available to
network transmission from OS Windows XP to devices with Android OS and does not work in the absence
built-in Wi-Fi module.

To configure the network in this way, for an already connected network, enter the section
1. « Wireless network connection» → "Change advanced options".
2. In the window that appears, select "Internet Protocol TCP/IP" and press
button " Properties".
3. In the window that appears, check if the required IP addresses, if not,
re-register 192.168.0.1.

The subnet mask is assigned automatically. Click OK.
4. Then in the tab " Wireless network" Mark " Use Windows
for settings", and at the bottom press the button" Add»

In a new window, write or mark:

1. network name (SSID)- the name of the wireless network
2. Authentication- choose joint
3. data encryption - WEP
4. key provided automatically - uncheck
5 .network key– key consisting of letters and numbers
6. confirmation- repeat key
7. Mark " This is a direct computer-to-computer connection, access points
not used»
8. In the tab "Connection" Mark "Connect if the network is in
range." Click OK.
9. Then go to " Change advanced options» and in the bookmark
« Additionally" Mark "Allow other users
use connection".

In the same way, set the parameters OS Windows XP on receiving PC.
Only in the column Use the following IP address» set the address of the receiving device: replace only the last digit of the address in the range from 2 before 254.
In the column " Preferred DNS server» set parameters host PC: 192.168.0.1.
Save changes by clicking OK.

WiFi Security

Because when using WiFi all information is transmitted by radio wave
WiFi networks are much more vulnerable compared to wired networks. The fact is that the radio signals sent by the access point ( WiFi router) and devices that are connected to the access point are available for interception by any similar device that is within the radius of "hearing" from the access point or from the client of this access point. That is, interception network traffic becomes very simple, accessible and inconspicuous. And the interception of network traffic allows you to collect the information necessary to attack WiFi net. As more access points become available, WiFi and the number of applicants is increasing "hack" WiFi net.

The most common motivation for hacking hotspots wifi, This connection to Internet through WiFi for free. For example, in your apartment is installed WiFi a router and not only your devices are connected to it, but also the computer of one of your neighbors.
You pay for the Internet, and your neighbor gets the Internet for free.
But " free internet" not the only reason why networks are "hacked" WiFi. The fact is that if an attacker gains access to your access point, he can access through it all the devices that are connected to your WiFi router. And this gives him the opportunity to steal your personal data. For example, passwords to mail, to Internet banks, your documents - in general, to much that you own.
Therefore, enjoy WiFi need with caution.

Here are a few rules to follow.

1. Don't connect to open public networksWiFi through a laptop
you have valuable information. And if you need Internet access
through open networks WiFi then use on your laptop
firewall and antivirus.
2. If you are using routerWiFi at home or in the office,
set up correctly WiFi router
A. Use protection type WPA2
b. If on your WiFi router there is a function WPS she needs disable .
G. If your WiFi router supports the administration function through the web interface,
need to disable access to this interface via WiFi.
Wifi web interface router must be available only through a network cable.
e. Turn off your router WiFi at a time when you do not use the Internet - at night
or when you leave your home or office. If the hotspot is open 24/7
this makes it easier for the cracker - he has a lot of time to carry out attacks
to your hotspot

How to bypass Windows password read

Modern technologies wireless communication already firmly entered people's lives. They are constantly developing and improving, while such technologies have great prospects. One such technology is WiFi, which allows you to connect your laptop to the network without any wires or cables. It should be noted that modern laptops, smartphones, tablets, printers, TVs and other equipment have a built-in WiFi adapter. But, despite the prevalence of technology, quite often there is a question of how to connect WiFi to Windows laptop xp. This is what will be discussed next.

Laptop setup

As you probably already guessed, before moving on to how to enable WiFi on a laptop with Windows XP, it should be configured. What does this mean? Each component of the computer needs to install special software - the so-called drivers. Wireless adapter Bluetooth communications and Wi-Fi is no exception. Without a driver, the system will not be able to turn them on.

In some cases, when you buy a laptop, you get a disc with the necessary software. In this case, setting up the system will not cause difficulties. You just need to insert the disc into the CD-rom or DWD-recorder, after which the autorun program will launch automatic installation. This will install all the drivers in the correct order. Moreover, for more convenient work with a laptop, various utilities will be installed - additional programs. But what if there is no such disk?

You shouldn't get upset. Here, too, there are no difficulties, since they can be downloaded for free. To do this, you only need to know your PC model. Next, go to the manufacturer's website, for example, if lenovo laptop, then you need to go to the manufacturer's website and find your model there. It is worth noting that the site will offer drivers for various operating systems, as well as for various components. We are interested in software for WiFi adapter and network card for Windows XP. After downloading the drivers, you can proceed to the installation.

If the laptop does not have drivers installed at all, then you should install them in a certain order. This is not critical, but correct operation system, first of all, you should install the drivers for the chipset ( motherboard) and then everything else.

After installing the driver, the system will detect new devices. And to work with WiFi adapter along with the driver, a program will be installed that allows you to turn the module on and off, as well as search for available networks. This completes the system setup, you can proceed to turn on and search for available access points.

Turning on the WiFi module and searching for networks

In order to enable WiFi on a laptop, there is a special button on which the WiFi icon is drawn (available on every laptop).

In some cases, the utility simply launches and you can turn the adapter on or off yourself. In other cases, it turns on and off at the touch of a button without running any programs. It is worth noting that the operating system absolutely does not affect this process, whether it is Windows XP or the seven, everything happens in exactly the same way.

So, after turning on the WiFi adapter on a laptop in Windows XP, an icon of a working module will appear in the lower right corner (slightly to the left of the clock). When you double-click on it, a window will appear in which you need to click the "Search for wireless networks" button. Next, you will see a list of available access points, from which you need to select the desired network by name.

If this option did not work, then there is an alternative way to connect a WiFi network on a Windows XP laptop. To do this, follow these steps:

1. Go to the "Start" menu, then to the Control Panel;
2. In the control panel, you need to find "Network Connections";
3. After that, you need to find the item "Wireless Network Connection" and enable it;
4. Next, connect the laptop to the network. To do this, right-click on the connection and select "View available wireless networks";
5. Here we select "Change network preference order";
6. After that, a window will open in which you need to select "Network by access point" and check the box "Automatically connect to the network", then close the window.
7. Next, in the wireless network connection, you must click "Update network list".

After that, you need to select the desired network and click "Connect". It is worth remembering that in the vast majority of cases, a password is set on the network to prevent intruders from entering, so after selecting the desired connection, you need to enter a password, and only after that you can join the group.

How to find out your WiFi password in Windows XP: Video

On this setting WiFi connections on a laptop with Windows XP is finished. Now, in order to connect the device to the network, you should again enter the "View available networks" menu, select the required name and click the "Connect" button.

If everything is done, then after the connection the status “Connected” will appear, and in the lower right corner on the taskbar you will see the corresponding message, which indicates that your laptop is connected to the network.

If you can't find the adapter's power button on your laptop, or it's broken or missing, then you can turn it on using Device Manager through Windows XP. To do this, right-click on the shortcut "My Computer" and enter "Properties". Next, select the "Device Manager" item and look for your adapter in the list of devices, which you want to enable.

Connection setup

First, let's go over the theory a bit. This will allow you to understand what Wi-Fi is and how to connect to it in a given situation and how to set up the system. This is one of the most advanced wireless technologies that allows you to create home networks without laying cables. The main advantage of this technology is that the transmission speed is not inferior to a cable connection. At the same time, the range of one access point reaches 100 meters with line of sight and about 10 meters in buildings.

The access point is base station, to which all devices equipped with a WiFi adapter are connected. As a rule, in the vast majority of cases, a router is used as such a station.

And before you create your network, it should be configured. It is to it that laptops and other devices are connected. Up to 200 users can be connected to one router, however, in this case, the data exchange speed will greatly decrease, since it is distributed equally among all users.

For example, if the router supports a maximum speed of about 100 Mbps and at the same time connects 10 users, then the speed for each of them will be 10 Mbps. It is not difficult to imagine what will happen if you connect 100 or more users.

In some cases, you need to further configure the connection on a laptop in Windows XP. If you did everything according to the instructions, but there is still no access to the network, then you should check the IP address. To do this, in the network environment, right-click on the wireless connection and select "Properties".

Next, in the window that appears, select "Internet protocol TCPIP" and click "Properties". After that, a window will appear in which you need to check the box "Use the following IP address" and enter the following values:

• IP address: 192.168.0.5. Please note that the numbers 192.168.0 are always the same, but the last digit "5" can be anything from 1 to 150, depending on the settings and capabilities of the router;
• Subnet mask: 255.255.255.0;
• Default gateway: 192.168.1.1.

Now you know how to set up WiFi on a Windows XP laptop. However, there are non-standard situations that can cause additional difficulties. In this case, the approach to solving the problem should be individual, since standard setting won't help here.

As you can see from the above, connecting a Wi-Fi network on a laptop with Windows XP is quite simple and within the power ordinary users without special knowledge. At the same time, setting up a connection will not take much time and effort. However, it is worth noting that the Windows XP operating system is already outdated, today the newer versions are Windows 7 and 8. At the same time, the latter are much easier to configure.

I have over 10 years of experience in the IT field. I am engaged in the design and configuration of commissioning. He also has extensive experience in building networks, system administration and working with ACS and video surveillance systems.
I work as a specialist in the company "Techno-Master".

In general, the task of configuring Wi-Fi in Windows XP is divided into two main tasks. The first is the task of setting up a connection to an existing Wi-Fi network, for example, to a router distributing wireless Internet or to another computer.

As part of the second task of configuring Wi-Fi in Windows XP, the task of organizing an access point from personal computer, so that other computers and other devices can access the Internet. Within the framework of this article, we will confine ourselves to considering only the first task, since the second is the lot of system administrators for which it is worth writing separate articles. Here we will limit ourselves only to the user experience of connecting to wireless networks and configuring them in Windows XP.

Connecting to an existing Wi-Fi network

If you want to set up a laptop connection to an existing Wi-Fi network, first, find the corresponding button on the laptop case, which includes built-in laptop wifi adapter. It usually looks like the one shown in the picture.

After that, a light on the laptop case should light up, signaling the inclusion of the Wi-Fi module. Usually, the exact combination of buttons is described in the laptop documentation. Next, go to Start, go to "Control Panel", where select "Wireless Network Connection", which should be enabled. The same should be done for setting up Wi-Fi in desktop computer right after WiFi settings module. If the Wi-Fi module is not detected, find it in the device manager in the "Network cards" section.


If it is not found there, then you have not installed the driver. Find them on the website of the manufacturer of your adapter or on the disk that came with it.

To successfully connect to Wi-fi, you need to know:

1. Network name
2. Network password
3. Network details (ip-address, gateway, DNS server addresses)

Sometimes in Windows XP, a wireless network connection may be responsible for some special program. It can be supplied with a laptop or Wi-Fi adapter and allows you to set up the necessary Wi-Fi connection. The usual utility is represented by an icon next to the clock. However, these programs are not always stable, so if it is possible to set up your wireless connection without using these utilities, use it. You can always force your operating system to configure your connection directly - to do this, go to the properties of the adapter in "Network Connections", go to the "Wireless Networks" tab and check the box "Use Windows to configure the network". This will allow you to configure your Windows network.

In this case, you need to configure the so-called SSID.

To do this, go to start - "Control Panel",

where go to "Network Connections".
There, double-click on "Wireless Network Connection"
where you can select the name of the desired Wi-Fi network to which you need to connect. The green bars next to its name indicate the signal strength level - the higher it is, the better.

If the wireless network you select is password protected, Windows XP will prompt you for it. Enter it and click connect.

After that, the operating system itself will take all the necessary steps to connect to this network. In the future, you will not need to enter a password when connecting to this network, of course, until you change it. In fact, this is the whole Wi-Fi setup in Windows XP.
However, there are situations when you need to connect to a network with a hidden name. In this case, you must manually create the desired profile yourself. To do this, go to Start, go to the "Control Panel", there go to the "Network Connections" item. After that, right-click on your "Wireless Network Connection", select "Properties",

where you need to open the "Wireless Networks" tab.
Pay attention to the "add" button - click on it, and after that check the box "Connect even if the network is not broadcasting", and also select the types of authentication and encryption.

You also need to set a network name.

In some cases, there may be a specific problem of the inability to connect a computer to a Wi-Fi network - when the router is configured in such a way that it does not give out an IP address via DHCP. We will not go into technical details, we only note that the task of setting up the network in this case becomes more complicated. To solve the problem, you need to go to the start, find there "Control Panel", select "Network Connections" in it, then right-click on your connection. - "Properties". There, find the item "Internet Protocol (TCP-IP)", select it and click "Properties". After that, you will have to manually enter the parameters of your wireless network. Often, they are:

• IP address: 192.168.1.111
• Subnet mask: 255.255.255.0
• Default gateway: 192.168.1.1
• Preferred DNS Server: 192.168.1.1

Or like this:

• IP address: 192.168.0.111
• Subnet mask: 255.255.255.0
• Default Gateway: 192.168.0.1
• Preferred DNS Server: 192.168.0.1

However, when setting these parameters hard, you should remember to disable them if you work in places with public wireless networks - otherwise, you will not be able to connect to them.

Problems setting up Wi-Fi

Often, most problems connecting to wireless networks are caused by an incorrectly installed adapter driver or the use of auxiliary utilities to connect. Reinstall driver or Windows usage XP as a network configuration tool usually helps to solve any problems. However, in some specific cases, this solution will not work.

For example, the list of Wi-fi networks displays names, but an error occurs when connecting to the desired network - perhaps the problem is in the router itself. It makes sense to switch it from "standard" mode to "Mixed" mode or mixed mode.

It often happens that the Wi-fi connection is constantly disconnected - in this case, the reason may be a low signal level. Increase its power or use a different antenna in the router.

The most common problem is connecting to the network, but the Internet does not appear. In this case, configure the TCP / IP protocol and manually enter the necessary ip-addresses and gateway addresses using the method described above.

If there is an Internet connection, but it works poorly and slowly - try to sort through the broadcast channels on the router - most routers have such a function. Indeed, in most routers, the channel is left by default, and if there are a significant number of such devices in the neighborhood, they can clog the air.

Also, some problems may occur when using different builds of Windows XP, for example, Zver. In this case, we can only advise you not to use self-made assemblies, but to use only original and licensed operating systems.

We hope that our tips have helped you in setting up your Wi-Fi network. If our educational program did not help us - do not be discouraged, try looking for advice on the forums, on Google, or ask us for it.

WiFi or Wireless Fidelity (wireless accuracy) is a technology for wireless data transmission over a special Wireless LAN channel. The WiFi network is half duplex, due to the technology itself.

This feature means that only one device operating as an access point can operate on one frequency. An access point can be either a computer with a Wi-Fi transmitter, or specialized devices - routers that support the WiFi wireless protocol.

There are two ways to build a network using the Wi-Fi wireless protocol.

Setting up a Wi-Fi network computer-to-computer in Windows 7

In this article, we will look at how to combine several laptops running Windows 7 into a wireless Wi-Fi local area network in Ad-Hoc mode.

To make it easier for you to navigate the Wi-Fi network setup, I will explain the following definitions:

Network host- a computer or laptop connected to the Internet and acting as an Internet gateway. A Wi-Fi connection will be created on this computer.

Other computers on the network- computers or laptops connected to a Wi-Fi network created on the main computer and having access to the Internet through this computer.

Setting up a network host

In the Description: field, enter a description of the computer, such as Stepan's Computer.

Click the Edit button.

In the Computer name: field, enter a computer name. The computer name must be unique. You cannot specify a computer name that is already in use on the network.

Note: By default, in all versions of Windows 7, Vista, and all versions of Windows XP except for Windows XP Home Edition, the workgroup name is WORKGROUP.

Click the wired network connection icon.

Click the Add button.

Click Create Computer-to-Computer Network

In the Network name: field, enter an arbitrary network name.

In the Security Type: field, select WPA2-Personal.

If other computers on the network are running Windows XP, select WEP.

In the Security key: field, enter the password.

The password must be between 8 and 63 characters. If WEP encryption is selected, the password must be 5 or 13 characters long. The longer the password, the better. To create a password, it is better to use a password generator.

In this window, click Turn on Internet Connection Sharing.

Click the Close button.

Setting up other computers on the network

Select the Properties menu item. Click the link Extra options systems.

Click the Computer Name tab.

In the Description: field, enter a description for the computer, such as Anatoly's Computer. Click the Edit button.

In the Computer name: field, enter a computer name. The computer name must be unique. You cannot specify a computer name that is already in use on the network.

In the Workgroup: field, enter the name of the workgroup. The workgroup name must be the same on all computers on the network.

If you don't want to change the computer name and workgroup name, just click Cancel.

Note: By default, in all versions of Windows 7, Vista, and all versions of Windows XP except Windows XP Home Edition, the workgroup name is WORKGROUP.

Click the network icon.

Right-click the wireless network adapter icon and select Properties.

Double-click Internet Protocol Version 4 (TCP/IPv4).

Check the box Use the following IP address:

In the IP Address: field, assign an IP address to the wireless adapter. The IP address must be unique and from the same subnet as the host computer's wireless adapter IP address. The network should not have devices with the same IP.

Since the host computer has a wireless Wi-Fi adapter IP address 192.168.137.1 is assigned, then on other computers on the network, IP addresses should be: 192.168.137.2, 192.168.137.3, etc.

Important: If the main computer of the network is running the Windows XP operating system, then its wireless adapter is assigned the IP address 192.168.0.1, which means that other computers on the network need to specify IP addresses: 192.168.0.2, 192.168.0.3, etc.

In the Subnet mask: field, enter the value 255.255.255.0.

In the Default gateway: field, enter the IP address of the host computer - 192.168.137.1.

Important: If the main computer of the network is running Windows XP, then the IP address of the main gateway must be set to 192.168.0.1

In the Preferred DNS Server: field, enter the IP address of the provider's preferred DNS server.

In the Alternative DNS server: field, enter the IP address of the provider's alternative DNS server.

Addresses of DNS servers can be obtained from the provider.

Press ok.

Click the network connection icon.

Double click on your network.

Enter password. Press ok.

All. We set up a computer-to-computer wireless Wi-Fi network in Windows 7.

Setting up Wifi at home and connecting a laptop through it

Consider the wireless option WiFi networks using a Router, when you already have a computer connected to the network (Internet) by a wired network and you still need to connect a laptop via WiFi.

This option is relevant, for example, if you have Internet from an Internet provider (say, Akado) for one computer that goes over the wire. And you intend to connect the laptop to the same existing network, but via Wifi, in order to access the Internet from it and be able to move it around the apartment without wires.

And also, if the independent availability of the Internet on each computer is important to you. (You can turn off the computer and go to work on a laptop with the Internet in another room or in the kitchen).

To make this possible, you need to understand the scheme, read the article, following the instructions.

Scheme 1. Merging wifi router, computer and laptop:

What you need to do to turn on the Router - step by step

If you are satisfied with the cable connection of the first computer (1) to the network and you do not plan to change it to Wifi, and Wifi is needed only for the second laptop computer (2), then you need to purchase a Wireless Router.

Such wireless router there is the possibility of a wired connection - a UTP (LAN) connector (s), a WAN ("input") connector and an antenna for wireless contacts.

Consider the example of the Router "ASUS WL-530gV2 Pocket Router (802.11g, 1xWAN + 4xUTP)" working according to this switching scheme. Which cost in Moscow in 2009 less than $100.

You can use, for example, the DLINK Router. The instruction is the same, with the difference that the WAN connector is marked "Internet" on it.

Router ASUS WL-530gV2 (Pocket router)

In addition to the router, an additional UTP-5 category cable, 1 m long, is also required (a regular cable for computer network with connectors).

How to connect the router

The router must be connected to the gap between the modem that "gives" you the Internet from the provider and the computer (1).

For this you need:

Turn off the power of the computer, modem. Put the router unconnected next to the modem.

Pull out the cable (UTP-5 type) coming from the modem from the network card of the computer (1) and connect it to the “WAN” input of the Router. This router model has it on the side.

The router is now connected to the internet. You have to distribute it.

We connect the computer (1) to the Router with the purchased additional UTP-5 cable:

One end in network card computer, the other - into the LAN1 connector of the router.

We connect the router to the power supply, through its own power supply (should be included with it).

The router is connected.

Now you can turn on the power of the computer, modem, router.

Setting up a computer (1) to access the Internet through the Router by wire

Computer setup is actually reduced to zero. If the Router has DHCP (IP allocation service and connection parameters for connected machines), it is enough to connect the PC connector to it and the computer will automatically receive an IP address from it.

The only thing is, if a specific IP address was set in the properties of the network adapter on the PC, then it must be reset to “Obtain an IP address automatically”.

IN Windows 7 this is done in:

« Control Panel\Network and Internet\Network Connections»

Go like this: Start, Control Panel, Network and Internet, then:

View network status and tasks -> Change adapter settings.

Choose your network adapter(where the router was connected), right-click - Properties, TCP / IP (IPv 4) - General.

Check "Obtain an IP address automatically" and "Obtain DNS server address automatically".

Click OK, then OK again.

In Windows XP:

Start, Control Panel, Network Connections - select your adapter ("Local Area Connection") - Internet Protocol (TCP / IP) - then everything, as in Windows 7.

Note that the computer will “get” the Internet only if the router is configured correctly and rebooted.

Setting up a Laptop (2) for Internet access

Go to the "Network Connections" of your laptop in the same way as you entered during Computer Setup (1), in accordance with the operating system already on the laptop.

Look for "wireless network connection".

Choose your wireless network, named as indicated in the Router. Let's say mynet.

Click "Connect". If the key was not set when setting up the router (which is not recommended), then the Internet will connect immediately. Or, a window will appear asking you to enter the “Network Key”.

All. With the correct configuration of the router, the Internet should already be available in the laptop.

You can check its work by going to some fairly reliable site, such as www.yandex.ru, www.google.com.

These entered settings will not need to be specified again after the next turn-off/turn-on of the Notebook. It will connect to the internet by itself.
