Enabling WiFi on laptops of different models. Enable and configure Wi-Fi on a computer Configure Wi-Fi on a Windows 7 laptop

Accessing the Internet via Wi-Fi on a laptop is the most convenient method, but often users have connection problems and cannot establish a connection. The reasons for the appearance of difficulties can be different. This article provides a detailed method on how to set up WiFi on a laptop, as well as the basic ways to enable the WiFi function on laptops to ensure wireless signal reception. The following guide will also be useful to users who need to restore a broken connection to the Internet through a Wi-Fi connection. To use a wireless connection, you must first enable the adapter built into the laptop.

WiFi adapter activation procedure

First you need to make sure that the Wi-Fi adapter of the laptop is active.

Unfortunately, each manufacturer tries to make the process of turning on the WiFi transceiver on their laptops different from the similar operation on the devices of their competitors, so the activation button for the function is different for all models.

In Asus laptops, to establish a wireless network connection, you need to simultaneously press two keys: "Fn" and "F2", in "Acer" - "Fn" and "F3". Lenovo is equipped with special switches located on the laptop case.

You can find out which button is used on a particular laptop by examining the pictures on the function keys from F1 to F12. Most manufacturers on the button use the images shown in the figure below.

Possible problems with the wireless signal receiving device

Often, even after the correct procedure to turn on the WiFi adapter, there is still no wireless connection. This problem occurs due to the following circumstances:

Incorrectly installed software (problem with drivers);
Damage to the computer by malicious software (viruses);
OS errors.

It is necessary to establish the cause and solve the problem, because without this, the laptop will not be able to establish a wireless connection. Most often, reinstalling drivers leads to a successful solution to such difficulties, however, sometimes the connection cannot be restored without completely curing the computer from viruses.

Setting procedure

After the owner of the laptop has made sure that the wireless signal receiver in the PC is active, you can go directly to solving the question: “How to set up Wi-Fi on a laptop with Windows?” This procedure has some differences depending on the version of the operating system installed on the PC.

Procedure for Windows XP

The following sequential steps must be followed.

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 Advanced system settings link.

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 Wi-Fi wireless adapter is assigned an IP address of 192.168.137.1 on the host computer, the IP addresses on other computers on the network 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.

Everything. 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 option of a Wifi wireless network using a Router, when you already have a computer connected to the network (Internet) by a wired network and you still need to connect your 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. Combining a 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 a wireless router has 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, you also need an additional UTP-5 cable of category, 1 m long (a regular cable for a 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 - to the network card of the computer, the other - to 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”.

V 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.

Select your network adapter (where you connected the router), 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”.

Everything. 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.

Data encryption "Klondike" is not just a computer game

Modern people face the need to connect to Wi-Fi everywhere: wireless networks are much more practical and more convenient than their cable counterparts.

It’s just that such WiFi privileges are mainly “used” by all kinds of mobile gadgets: phones, tablets, smartphones and most modern laptops. Accordingly, the question arises: why is a “classic” personal computer worse? After all, working on a stationary computer is much more convenient, and connecting cable Internet often causes 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 so that the computer "catch" invisible wi-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.

Can a regular computer be connected to wifi?

Some of the difficulties with connecting Wi-Fi on a personal computer are by no means connected with the "prejudices" of the developers or the unfortunate fate of this device.

The fact is that mobile devices and modern laptops are initially equipped with a built-in Wi-Fi adapter for connecting to a wireless network (which is not available on a desktop computer). However, such devices are mostly designed for short-term access to the network, and have a rather meager set of functionality.

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

A cable Internet connection for a desktop computer is more stable than a wireless Wi-Fi connection. So, with a WiFi connection, the reliability and speed of the network directly depend on the number of active connections, channel congestion, room architecture, and many other third-party factors.

Therefore, deciding to connect your home computer to wifi solely for aesthetic reasons is 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 less.

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

How to connect your 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 user-processed data to the router.

The most popular and inexpensive solution here would be to choose a removable USB adapter for the computer.

In order not to get a “pig in a poke”, it is better to buy a device from well-known and time-tested manufacturers: TP-Link, D-Link, etc.

If you purchased the adapter from an official distributor, then the device comes with a disk with a special program for installing drivers.

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

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

2. Insert the disc into the drive, run the autotuning utility and click the "Next" button when prompted by the program.

3. After installing the driver in the "Network Center" folder for Windows 7 (or "Network Connections" for Windows XP), you will see a new shortcut (in addition to the usual "Local Area Connection"). The name of the label will contain the brand of the manufacturer of your adapter.

4. Now you can connect your desktop computer to wifi. To do this, right-click on the shortcut -> "Connection" -> Select the name of your Wi-Fi network and enter the password.

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

In addition to the “classic” purchase of a brand new licensed adapter, there are times when a user needs Wi-Fi on a computer “here and now”, and he borrowed from friends / purchased an old used WiFi adapter.

The disk with the driver for 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 to connect a desktop computer to wifi you should:

Connect the computer to be configured to the router using a cable (if possible).

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

If a cable connection to the router is not possible, download the driver you need on any computer connected to the Internet, and use removable media (flash drive) to copy the archive to your wired computer.

2. Next, right-click once on the "My Computer" shortcut, then "Manage" and select "Device Manager" here. In the "Network adapters" section, find the name of our USB adapter, right-click on it and select the "Update driver" menu item. Next, specify the folder to which the archive with the necessary drivers was copied and click "OK".

3. Upon completion of the installation, you will be able to connect your desktop computer to wifi. To do this, in "Network Connections":

Choose a new label;

Click on it with the right mouse button;

Select the "Connection" menu item;

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

Enter the password and you can use the Internet.

In this article I will tell you how to set up wi-fi from scratch. First you need to set up a wireless network on the router, and then on the laptop. With the help of a simple step-by-step instruction, even a beginner will be able to set up the Internet on TP-Link and D-Link routers, which are most common in the CIS.

Setting up a wi-fi router

Step 1. We connect the router to the network using the power supply. Turn on the power with the ON button, if the router has such a button.

Step 2 We connect the router to a laptop or computer using an ethernet cable (patch cord) that comes with the router. It is necessary to connect the cable to the port of the network card of the computer and to the LAN1 port of the router. (In no case, not to the WAN port - you won’t be able to configure it through it)

Step 3 We check that on the computer in the properties of the network card we have selected automatic receipt of the IP address. To do this, go here: "Start" -> " Control Panel» -> « Network and Sharing Center» -> «» -> « LAN connection»

Attention! In chapter " Change adapter settings» You may have multiple connections displayed. For instance, "Local Area Connection" , "Local Area Connection 2" , "Wireless Network Connection" , "Bluetooth Network Connection 2" etc. How to find the right one among these connections?

Firstly, By default, a wired connection in Windows 7 and 8 is called Local Area Connection. If no one managed to rename it manually, then it will be called that way. Unless there may be a number at the end - most often "2". This is the case if several network cards are installed in the computer (relevant for stationary computers, because in a laptop in 99% of cases there is only one wired network adapter from the factory)

Secondly, the connection we need should be active, since you connected the computer and the turned on router with a cable: the connection icon should glow in a bright color (usually blue if your Windows uses a standard icon pack), i.e. the icon should not be grayed out. See picture:

Here, we found the right active wired network connection.
Step 3.1. Right-click on the active wired connection we need and select " Properties":

Step 3.2. In the window that opens, click the button " Properties":

Step 3.3. Select with the left mouse button Internet Protocol Version 4 (TCP/IPv4) " and press the next button " Properties»Bottom:

Step 3.4. We set both switches to the upper positions so that it is " … … … automatically»:

Step 3.5. Press the "OK" button to save the settings.

Step 4 Open the connection window again:

Step 4.1. Press the button " Details":

Step 4.2. In the window that opens, find out the IP address of the default gateway:

In most cases it is equal to 192.168.1.1

Step 5. Open the browser to go to the web interface of the router.

Step 5.1. In the address bar, enter the gateway address and press Enter:

Step 5.2. Enter login and password:

Attention! You can find out the login details in the instructions for your device. Included with the router may be both instructions on paper and in PDF-document format on the attached disk.

If the instruction is lost, you can try to download it on the manufacturer's website. For example, http://dlink.ru , http://asus.com , http://tplink.com .

Often in a new device, the default login = admin and password = admin . It also happens that the login = admin and the password is empty.

Step 5.3. After you have logged into the web interface of the router, open the wireless network settings (wi-fi):

(Illustrated with TP-Link TL-WR841ND and D-Link DIR-300 NRU as an example)

Step 6 Actually setting up a wireless connection.

Step 6.1. Disable WI-FI protected setup this feature is a serious security hole and could allow an attacker to hack into your Wi-Fi network and gain access to your information.

Step 6.2. We check that the Wi-Fi network is enabled: the “Enable wireless” checkbox is checked if it is D-Link.

Step 6.3. Set a name for our wireless network.

If the default is dlink or home, then it is recommended to specify some original name in order to avoid confusion with neighboring networks of the same name.

Step 6.4. Set the security settings. We strongly recommend using the following options:

security mode WPA2 ;
encryption type AES;
key type PSK(aka Personal Key).

After specifying all the parameters, do not forget to click the save settings button!

On a TP-Link router:

in D-Link:

Setting up Wi-Fi on a computer (laptop)

In this section, we will show you how to set up wi-fi on a windows 7 laptop.

Step 1. Find on the taskbar near the clock network connection icon and click on it with the left mouse button once. A list of available wireless networks will open:

Step 2. Find your wireless network in the list (it will have the name you specified in the previous paragraph) and click on this network with the left mouse button.

Step 3. Leave the "Connect Automatically" checkbox checked and click the "Connect" button:

Step 4. Enter the Wi-Fi network security key. This is the character set you specified in the Network Key field. After entering the key, click "OK":

After clicking "OK", it connects to your wireless network.

After a few seconds, the previous window will disappear, and the network connections icon next to the clock will change its appearance.

Now, when you click on the network connections icon, you will see that the computer is connected to your wi-fi network, but at the top you can see the inscription “ Without internet access» , because we have not set up the Internet on the router yet:

Setting up the Internet on the router

We set up a wi-fi network on the router and connected to it from a computer. We just have to help the router see the Internet so that the router can distribute the Internet to any devices that connect to it via wi-fi or cable.

Step 1. In order for the Internet to appear on computers, you need to set up a connection with the provider on the router. We show on the example of the same D-Link

Step 1.1. Type the IP address of the router in the address bar

Step 1.2. Enter your login, password and click " Log in»:

Step 2. We go to the Internet settings section. For different manufacturers of routers, it may be called differently: WAN Setup, Internet settings, etc. In our D-Link, this section is called "Internet Setup":

Step 3 We get to the WAN port settings section.

Step 3.1. Remove the checkbox "Enable Access Point Mode".

Attention! Other manufacturers may refer to this setting as "Disable NAT". The bottom line is that the "Access Point" mode disables NAT and turns the router into an access point. This option is useful if this router is connected not to the provider, but to another one of your routers.

Step 3.2. Select the type of connection with the provider.

To find out what settings you need to choose to connect specifically to your provider, you can:

in the contract;
on the provider's website;
calling the hotline of the provider

These days, the most commonly used type is Dynamic IP.

Step 3.3. If your ISP only allows connection from a registered MAC address, you have 2 ways to resolve the issue.

Go to the provider's office with a passport and register a new MAC address;
Specify in the MAC address field the MAC address of the network card of the device from which you successfully accessed the Internet before purchasing the router. Usually, this is the MAC address of the computer's wired network card.

Step 3.4. Specify the DNS servers, if the instructions from the provider require it.

Step 3.5. Select the MTU value. If the provider does not require you to change this value, we recommend leaving it as it is: 1500 .

Step 3.6. Save settings

Attention! If you have lost the contract document with the provider, which contains the details, then in extreme cases you can always drive up to the office of your provider with a passport and find out all the comprehensive information: connection type, MAC address, login, password, MTU, etc.

Faced with the problem of how to set up Wi-Fi on a laptop (Windows 7), users are lost, although this is not done for long. The user will only need to find a network cable for a while and clarify the values \u200b\u200bof some settings with the technical support of his provider.

When is tuning required?

The most pleasant option is when, when you connect the Internet, a friendly specialist comes into the house, presses the buttons, connects the wires - and everything starts working. But this is not always the case. When you may need to set up wireless Internet:

When connecting the router for the first time, for example, if the user decides to change the regular router to a wireless router.
After reinstalling the system. The question of how to set up Wi-Fi after reinstalling Windows 7 on a laptop and PC is one of the most common.
In the event of a system failure, firmware update, or ill-conceived actions in the network settings.

In any case, even an inexperienced user can handle the problem of how to set up Wi-Fi wireless Internet on a Windows 7 laptop.

Please note that in order to (with different OS), you will need special instructions. You can find it on our website!

preliminary stage

Before you set up a Windows 7 Internet connection via WiFi, you will need to enable the Wi-Fi radio module on your laptop - using the button or system settings.

On some laptop models, you can find a separate button to turn on the radio module - it is marked with a characteristic icon. But more often, a combination of buttons on the keyboard is intended for these purposes:

"Fn" - located between Ctrl and Win;
One of the buttons of the row "F", you can identify it by a characteristic icon.

Thus, the combination may look like "Fn + F3" or "Fn + F11".

To enable the radio module through system parameters, you will need to do the following:

Open subsection "Network and Internet" v "Control Panels" or use the system search.

Select "Network status and tasks", and then click the mouse "Adapter Options".

Right click on "Wireless network"- a menu will appear in which you need to select "Enable".

How to set up an access point?

Before setting up a Wi-Fi connection, the user will have to fill out a window "Local Network Properties" in Windows 7. This will require:

Reopen "Adapter Options" and right click on "Wireless network". Select "Properties" from the menu.

Check the boxes as shown in the screenshot.

If you still have questions about setting up a wireless WiFi network on a Windows 7 laptop, the video will help you understand it in more detail.

Please note that it is much easier to turn on the distribution than again! But in any case, the main thing is not to give up! Nowadays, the possibilities of users are almost limitless!

How to connect to WiFi?

During the initial Wi-Fi setup, you will have to connect the router to the laptop using a cable, later this cable can be removed.

Now you can set up a WiFi router on a Windows 7 laptop (for example, TL WR 720n), you need to start by opening the web interface. Final setup step:

Open a browser, you will need to type the IP address of the web interface in the address bar (for TL WR 720n it is 192.168.0.1, but 192.168.1.1 is more common).
For authorization, standard data is used: admin as both password and username. If suddenly the password does not fit, you can try 1234.

If the setup for Windows 7 is done correctly, then the result will be wireless home Internet.
