How to set up a laptop to receive Wi-Fi. How to connect a laptop (computer) to the Internet via Wi-Fi? Wi-Fi connection problems

For a high-speed and high-quality Wi-Fi connection, it is recommended to purchase a router that supports the 802.11n standard with data transfer speeds of up to 300 Mb/s. In addition, it is better to purchase a router from a well-known and reliable manufacturer (Asus, D-Link, Netgear, TP-Link). You can also use devices that support the newer 802.11ac standard.

A common mistake made by a large number of people is not incorrect configuration, but incorrect location of the router. As a result, Wi-Fi speed and reliability are reduced. To ensure proper placement of the router, select locations that are away from electronic household appliances such as microwave ovens and cordless phones. The fact is that these devices, just like Wi-Fi standards, operate at a frequency of 2.4 GHz. And it is the proximity of the router to them that creates interference and slows down the Internet speed.

In addition, obstacles can be walls, metal structures, furniture, and even the person himself. As a result, it is best to place the device as high as possible on the wall, away from various obstacles.

Setting up Wi-Fi for a local network

First of all, before setting up Wi-Fi, you need to connect a computer running Windows 7, 8 or 10 to the router via a network cable. Before starting setup, you should make sure that the connection has been established. To do this, you need to find the corresponding icon on the taskbar on your computer next to the clock. After this, you need to start setting up the connection. This setting will require entering the following data into the connection properties:

1. IP address: 192.168.0.2
2. Subnet mask: 255.255.255.0
3. Default Gateway: 192.168.0.1
4. DNS: 192.168.0.1

If there are other data specified in the manual, this is what you should enter. Next, to set up Wi-Fi, you should open the command line. This can be done through "Start", indicating in the search column "cmd" . After this, a command line will open in which you will need to enter "ping 192.168.0.1".If the configuration result is positive, the response should receive packets from192.168.0.1 . If a notification appears about exceeding the waiting limit, then you should find out what IP address the router accepts on the internal interface. You can do this by looking up the information in the manual that came with your device.

If you cannot solve the problem, or the manual itself is missing, you can try setting up Wi-Fi by changing IP 192.168.0.1 and 192.168.0.2 to 192.168.1.1 and 192.168.1.2. And then, check the address 192.168.1.1.

To set up a wireless network,you need to go to the section"Wireless Settings"(wireless network settings) and give the name of your own Wi-Fi network. This must be done in the line"Name (SSID)". Then you should select the region and indicate in the paragraph"Channel" (channel)value "Auto". This will allow the Wi-Fi router to analyze and identify the channel that is most free from interference. Complete the setup by clicking on the icon“Apply” (accept/save).

Security

The security of a Wi-Fi network is one of the main conditions for its reliable and fast operation. Unauthorized connection to the network by a third party can significantly reduce the speed of the Internet. Therefore, you should choose your password very carefully. There are three main types of encryption - WEP, WPA and WPA2. They also differ in the possible number of characters to create a password. At the same time, WEP is considered more unreliable and weaker. Based on this, it is better not to use this encryption method. WPA and WPA2 are much more reliable. Despite the fact that these encryption methods cannot protect the user from unauthorized connections, their use will significantly reduce such risks. In order to configure them, you must activate “WPA-PSK (TKIP)” or “WPA2-PSK (AES)” in the “Wireless Settings” tab. Next, you need to set a password (in “Security Encryption”), which is best created from the maximum number of characters allowed by the encryption method.

Additional settings

In order to more reliably set up a Wi-Fi connection, you should use the ability to specify in the router the network addresses (MAC) of all computers that can connect to the network. To do this, you need to enter the “Wireless Settings” item. Next, you will need to click on “Setup Access List”. This will make it possible to see all devices connected to Wi-Fi.

In order to find out the MAC addresses of the modules of specific devices, you need to type “ipconfig /all” in the command line on your computer or laptop, then select the devices for which the Wi-Fi connection will be available. After selecting them, you must click on “Add” and check “Turn Access Control On”. Next you need to click on “Apply”.

Setting up Wi-Fi for an external network

To set up the Internet, you need to connect the appropriate network cable to the Wi-Fi router. The interface for connecting such a cable is called WAN. Then, you need to specify the settings of the provider you are using in the router, which can be found out by calling technical support. In addition, they can be viewed in the concluded agreement. We must not forget about DNS, which is also worth setting up. You can check the availability of the Internet on the local network by finding out whether the exchange of packets between interfaces is allowed.

Errors in setup and incorrect operation of the Wi-Fi network

1. Possible overlapping of the Wi-Fi network by a third-party router. Very often the cause of a weak signal is the influence of a neighbor's router. This is due to the fact that, as a rule, routers use the same default data channels (13 channels). In order to determine which channel is best to use, you can use a program downloaded from the Internet. There are quite a large number of such programs and, as a rule, they are free. After this, you can configure a suitable (free) channel.
2. Insufficient Wi-Fi coverage area. To increase the range of Wi-Fi, you can use several access points that will interact with each other and distribute the signal further. However, in addition to the cost of new equipment, a significant negative factor of this method is a noticeable decrease in Wi-Fi speed.
3. Interrupting the router. The likely cause of frequent loss of Wi-Fi signal is instability of the power grid. At the slightest power outage, the router may stop working. To solve this problem, you can use a special uninterruptible power supply (often used for a computer), through which you should connect the router to the power supply.
4. Wi-Fi interruption. This is due to the fact that the network adapter on the computer and the router are made by different companies. To resolve such problems, simply update the device software to the latest version.

Connecting to a wireless network is the most convenient way to access the Internet at good speed without unnecessary wires. However, to enjoy all the benefits of a wireless connection, you must first understand how to set up Wi-Fi on a laptop.

Enabling the adapter

Before you start creating a new connection, you need to check if the Wi-FI adapter is turned on.

Each laptop model has its own function key to turn the adapter on/off. For example, ASUS laptops use the combination Fn+F2, and Acer laptops use Fn+F3. On some Lenovo models, adapter status is controlled using a hardware switch located on the front panel.

To determine which key you have installed, look at the F1-F12 row. One of the buttons should have an icon - an antenna that distributes a signal. Press this button in combination with the Fn key and check that the Wi-Fi adapter indicator light changes from red to blue or green.

What to do if the Wi-Fi adapter does not turn on?

There are situations when, after pressing a function key, the adapter does not turn on. Typically this problem occurs due to one of the following reasons:

• Incorrectly installed drivers.
• Incorrect operation of the system.
• Virus infection of laptop.

Until you eliminate the cause, the question of how to set up Wi-Fi in a laptop will not receive a positive resolution. Most often, the problem lies in incorrectly installed drivers, but it would also be a good idea to check the system for viruses. If no malicious applications are found, reinstall the Wi-Fi module drivers and try turning it on again.

Today it is difficult to imagine a modern apartment, or even more so an office, that is not equipped with the appropriate set of office equipment: computers, laptops, tablets, mobile phones. And where all these devices are available, there should naturally be the Internet. He has firmly entered our lives, occupying one of the most prominent places there. On the Internet we study, work, have fun, relax, and communicate. Therefore, providing comfortable access to the World Wide Web for yourself and your loved ones is a problem that sooner or later every person has to solve. Fortunately, now we have a reliable assistant that allows us to carry out the most effective and simple solution to this issue without any additional intellectual and financial costs. We are, of course, talking about Wi-Fi technology.

But in order to use the “over-the-air” Internet, you need to know where to find and how to turn on Wi-Fi on your computer. We tried to present the answers to these questions in this article.

What is WiFi?

Wireless Internet technology has become part of our everyday life. We habitually identify Wi-Fi with a convenient, reliable and fast Internet connection, which we encounter at home, at work, in public places - in airports, cafes, shopping centers.

Answer the question “what is Wi-Fi?” the simplest way is this: this is a network protocol, with the participation of which communication is carried out between an “access point” and a “client”, or an “access point” and several “clients”, packet data is exchanged on a local network or via the World Wide Web.

Currently, the abbreviation Wi-Fi means nothing and is not officially deciphered in any way, but when creating this protocol, the developers “gave it a name” by analogy with Hi-Fi (High Fidelity). It stood for “Wireless Fidelity” - wireless precision.

Benefits of use

Of course, the “over-the-air” Internet is not an ideal technology. You can give several examples of the difficulties that may arise when using it. One of the most widely known is the so-called “noisy” connection. Many household appliances (for example, microwave ovens) emit in the range used by this protocol, and alternative connection devices (for example, Bluetooth) operate. Interference can also be caused by walls and ceilings. All this negatively affects the speed and quality of access.

At the same time, there are no less positive aspects from using it at home and in the office. We list just a few and the most obvious of them:

1. Low cost of wireless networks and installation of several access points that will provide stable coverage throughout the entire territory. At the same time, there are no cables, extension cords or adapters that constantly get tangled and clutter up the space. An “aerial” connection is indispensable in rooms of historical value, as well as in rooms with obstructive architectural features;


2. This protocol provides full access to the Internet to any device - be it a mobile phone, tablet, laptop or desktop computer - without being tied to a specific location. Access to the global information space through this protocol is an opportunity to comfortably use the Internet while lying on your favorite sofa;


3. Wi-Fi allows you to synchronously use a large number of active connections. Having established a wireless connection, you don’t have to worry about how many computers and mobile devices will be accessing the Internet at the same time.

What types of Wi-Fi modules are there for a computer?

All popular devices now come with adapters by default. They can be connected to the Internet out of the box, but what about those who have a desktop computer? The answer to this question is obvious - you need to purchase an additional Wi-Fi receiver, install, connect and configure it.

We will talk more about how to install Wi-Fi on a computer below. Now we propose to decide what types of receivers there are, what is their difference, specificity and advantages.

“Air” adapters come in two types: external and internal. External ones are the most commonly used and easier to operate. The external receiver looks like a miniature USB drive (flash drive). It connects to a USB connector on the front or back of the computer, either directly or via a USB cable.

The internal adapter is slightly larger and you will need to open the computer case to install it. Therefore, buy an internal receiver only if you are confident that you can figure out how to install it on the motherboard yourself. When installing an internal module, you must first disconnect the antenna from it, insert the board into the corresponding port on the motherboard (the PCI interface is most often used for this) and return the antenna to its place.

Further manipulations for installing and turning on wireless adapters are the same and do not depend on the modification and method of connection to the computer.

How to install drivers?

Any Wi-Fi receiver is supplied with a disk from the manufacturer, which contains the drivers necessary for full operation of the device. In addition to drivers for a specific device, the disk may also contain drivers for other adapter models, so during installation you need to be careful and not miss choosing the device for which you are installing drivers.

Otherwise, the driver installation procedure is standardized and provided with an intuitive interface with detailed tips from the “Found New Hardware Wizard.” Just carefully read the messages that will appear on the screen and click the appropriate “Next”, “OK” and “Done” buttons.

Most adapters are automatically recognized by current computers and can work even without installing drivers from the bundled disk. Just connect the device to the desired connector and wait a few seconds. As a rule, after this a message will appear in the tray stating that new equipment has been found, identified and installed, which is ready for use. However, universal drivers cannot completely replace specialized software. Therefore, we advise you not to neglect installing drivers, even if everything seems to work flawlessly at first glance.

The driver disk for your Wi-Fi receiver model may also contain a special utility from the developers, which is designed to facilitate the process of setting up Internet access. Moreover, this utility will allow you to further control your Internet connection, monitor the speed and volume of data transfer.

In the “Security Key” field, you must enter the connection password. For greater security, check the “Hide characters” checkbox so that the password cannot be read over your shoulder.

The final touch - if you plan to use this connection as the main one in the future, then check the “Start this connection automatically” checkbox. Then click the "OK" button.

Installing a device in Windows 8

To connect a wireless connection in Win8, do the following:

1. Click on the Wi-Fi icon in the system tree on the taskbar or call Settings Charm through the Charms Bar (similar to pressing the win+I combination). The Wi-Fi panel will appear on the right side of the screen;

1. you will see the entire list of wireless networks available for connection. Select the one that is configured for you and click the “Connect” button;

1. The next step is to check the network connection conditions. The system will check the requirements of the selected network and prompt you to enter the necessary data;

1. After checking the network requirements, the system will prompt you to enter a password. Enter the security key you know and click the “Next” button;

1. If the password is entered correctly, you will see the message “Connection complete”, which means the connection to the Internet has been established.

How do I turn off my device?

To turn off Wi-Fi or edit previously entered data, you should select the wireless networks icon in the tray (relevant for Win7 and Win8) and in the drop-down list of all available connections, select the one that you configured earlier. To disable, use the “Disable” button, and to edit, right-click and select “Properties”. In the “Connection” and “Security” tabs, you can either disable the device or make changes to the password, encryption type, or security level.

For Win XP you need to do the following:

• how to install a wireless network on a laptop

A laptop, like any computer, can be connected to a shared local network to exchange various data with other computers on the network or to access the Internet.

Instructions

This can be done using an Ethernet network port or using wi-fi wireless technologies. If the physical connection is created, all that remains is to install the correct software settings. Make sure you have a network connection by launching Network and Sharing Center. If the connection is established, there will be an active network icon in the connections section.

Set the correct connection settings in the TCP/IP section. If IP addresses are registered manually on your local network, specify a unique address for the network connection, then the gateway and subnet mask. If the addresses are a router, leave the settings on automatic. Click on the “Save” button if you have made settings in the system.

Check the computer properties to ensure that the laptop is in the same workgroup as the local network computers. Look at the map of the entire network in the Network and Sharing Center. Try ping the IP address from another computer on the network. Make sure that network traffic scanning programs or antivirus programs are not blocking the network connection. Turn off Windows Firewall. Restart your computer, as not all network settings may work right away.

If the ping command was completed successfully and you saw a laptop in the network map, then the connection was successful. All you have to do is select a folder for exchanging data over the network and open access to it to other computers. You can use different folders. As a rule, this folder is often the “Shared Documents” category in the local drive C. Do not forget that all data located in shared folders will be fully accessible to other users of the local network.

Video on the topic

Technologies such as infrared and Bluetooth are becoming less and less popular because they are being replaced by modern wireless networks. Wi-Fi is being used more and more, as there are a large number of free hotspots in cities.

Instructions

For a wireless connection using a specific key combination. Usually this is Fn + F2. To connect to the Internet you need to look for specific access points. On a personal computer, you can connect to Wi-Fi only if you have a special removable device. Ask a peripherals consultant about Wi-Fi devices for a personal computer. Prices may vary, but mainly depend on the signal reception radius.

Once the device is purchased, unpack it and insert it into the USB drive. If you have USB 3.0 technology on your computer, then insert Wi-Fi there. The computer system will automatically detect the new device. The kit also includes a CD with drivers. Insert it into the drive and install all the drivers. Next, restart your computer so that all saves in the system are recorded. After the reboot, an icon will appear in the tray that will show the Wi-Fi status.

Go to the “Control Panel” item. This can be done using the “My Computer” shortcut. Next, click the shortcut called “Wireless Networks”. Here are all the settings that relate to W-Fi technologies, as well as Bluetooth. Click the "Turn on Wi-Fi" button.

After this, the wireless technology will be active, but it is not yet possible to connect to the Internet, since you need to look for special access points that can be locked with passwords so that unauthorized persons cannot penetrate the system and automatically connect to the connection. To do this, click the “Find a new connection” button. The system will automatically begin scanning access points that are in operation.

If no such systems are found, try scanning in another location. Once a connection is found, try connecting. As practice shows, some cafes and educational institutions use free access points that allow you to connect to the Internet. You can find a list of such establishments on the Internet using search engines.

Wi-Fi is a type of wireless Internet access that is ubiquitous in the modern world. Almost all laptops and PDAs today have built-in Wi-Fi.

Setting up Wi-Fi on a laptop is a fairly simple operation, however, inexperienced users may encounter a number of problems, and in this article we will take a detailed look at creating a Wi-Fi connection according to the standard scheme for any laptop.

To configure the wireless module, you do not need to have special knowledge in computer technology. Modern software is as friendly as possible to inexperienced users, so the procedure will take no more than a few minutes (except in cases where the problem is related to hardware faults). Let's look at setting up Wi-Fi on a laptop step by step.

What is necessary?

In order for the Internet to work properly, you need, in addition to a configured laptop with a Wi-Fi module, to connect a router from which the signal comes. Without an Internet access point, Wi-Fi turned on on your computer is absolutely useless.

Instructions

To set up the Internet on your Laptop via Wi-Fi, you need to do the following:

1. With the PC turned on, activate the wireless module using a key combination. It is different for each laptop computer, but most often it is a combination of the FN key + button with the Wi-Fi icon (most often located on the top row of the F1-F10 keys);
   
2. go to the control panel via the Start menu;
   
3. then select the “Network and Internet” section;
   
4. in the menu that opens, select “Network connections”;
   
5. a list of available Wi-Fi access points will open;
   
6. Click on the required name to connect to the router.

Typically, the address at which you need to log in to the control panel, as well as your login and password, are written on the bottom side of the router.

Now setting up Wi-Fi on a laptop and router will not be an overwhelming task for you. Also on our website you will learn how to fix various problems and malfunctions associated with wireless connections.
