Today it's hard to imagine modern apartment or, especially, 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, comfortable provision of access to World Wide Web for yourself and your loved ones - this 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. It's about, of course, 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 equate Wi-Fi with convenient, reliable and quick exit to the Internet, which we encounter at home, at work, in in public places- at 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 the “access point” and the “client”, or the “access point” and several “clients”, packet data is exchanged in 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 accuracy). It stood for “Wireless Fidelity” - wireless accuracy.

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 people emit in the range used by this protocol. Appliances(for example, microwave ovens), work alternative devices connections (for example, Bluetooth). Interference can also be caused by walls and ceilings. All this negatively affects the speed and quality of access.

At the same time positive points from using it in home and office conditions no less. We list just a few and the most obvious of them:

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;

This protocol provides full access to the Internet to any device - be it mobile phone, tablet, laptop or desktop computer- without reference to a specific place. Going global information space through this protocol it is possible to comfortably use the Internet while lying on your favorite sofa;

Wi-Fi allows synchronous 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 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.

There are two types of “air” adapters: 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 in size and to install it you will need to open the computer case. 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 indoor module You must first disconnect the antenna from it, insert the board into the corresponding port on the motherboard (for this you most often use PCI interface) and return the antenna to its place.

Further manipulations for installation and switching on wireless adapters do not differ and do not depend on the modification and method of connection to the computer.

How to install drivers?

Any Wi-Fi receiver supplied by the manufacturer with a disk containing the necessary full-fledged work driver devices. In addition to drivers for specific device, the disk may also contain drivers for other adapter models, so during installation you need to be careful and not skip selecting the device for which you are installing drivers.

Otherwise, the driver installation procedure is standardized and intuitive clear 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. Nevertheless 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 disk with drivers for your Wi-Fi receiver model may also contain 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.

Hello blog visitors.

Technology wireless communication is in great demand today. Especially for owners of laptops, smartphones and tablets. And what more demand, the more often they may occur various problems. Later in the article I will tell you how to connect WiFi to Windows laptop 7, and also highlight the main points related to this issue.

general information

Wireless connections via WiFi router today are considered the norm, since users no longer need to run a lot of wires around the rooms. At the same time, now users are not at all tied to a specific place. This kind of connections enable you to interact with the network. In addition, the devices are used to distribute the Internet. They are considered most suitable for people who can move freely within the range of the router.

As with any other technology, some problems may arise here too. Further in the text I will try to consider the main ones. And of course I’ll tell you the possible solutions.

Settings

The first step is to ensure that your wireless device is installed and ready to use. To do this, we go to " device Manager", by pressing " Start" and go to " Control Panel" We will see a list of components from which we need to select “ Network adapters" The hardware used on the computer will appear. We mark the line that mentions Wi-Fi and check the functionality of the component in the properties.

If there are problems with the software, you need to update it to the required version. For this purpose, an appropriate device is usually supplied with the laptop. portable memory with all the necessary distribution. If it is not there, you can always contact official page creator mobile computer or directly the element itself. Here you need to indicate the hardware model, operating system and its bit depth.

You can resort to this same method after reinstalling Windows, because even if you have a disk with drivers, they will most likely be designed for a different operating system.

After successful completion, go to the “ Network connections" in tray. A list of all available connections that the equipment can detect should appear.

Networking

It’s worth saying right away what to create work network It won't work without a router. If there is a need only to exchange information between individual machines, you can simply enable required device, and everything will work.

If an Internet cable is connected to it, users have the opportunity to go to the World Wide Web. True, for this you need to enter additional settings:

Connection

As mentioned above, without drivers for the device, you won’t be able to do anything. Therefore, first of all, we place the necessary information in the system software.

If you have everything installed correctly and have the equipment, let’s move on directly to the connection itself. To do this you need to run it yourself wireless transmitter on a laptop. This is usually done by clicking the " Fn" and one of the functional range " F1-F12" Moreover, on laptops from Acep and Asus, the combinations are different. However, the same can be said about Lenovo or HP. On most of them, on the corresponding key there is an icon in the form of an antenna and waves emanating from it.

After this, the module will start and automatic search. In the lower right part of the screen we will see the corresponding icon. After clicking on it we will come across a list of all available connections. Typically, each of them has its own security set of characters, and if you change the password on the network, you will not be able to connect so easily.

To find out the line we need, go back to the browser and type “ 192 .168.0.1 " Enter the login information to the router. We are interested in the password item that was mentioned earlier.

If everything is entered and configured correctly, there should be no problems. Sometimes users cannot create a normal network using the tp-link adapter. This is usually due to either drivers or an incorrect password. Most often, users forget to switch the language or the “ Caps Lock».

Some encounter problems as a result of the fact that previously the computer was connected to the World Wide Web only through a wire. To correct the situation, you need to go to the tray, find the corresponding icon, right-click on it and select “ Control center…».

Next we go to “ Change adapter settings" Find the shortcut " Wireless connection", and open on it " Properties».

Now we are looking for the item that indicates TCP/IPv4. We mark him and call him again “ Properties" Go to the tab " Are common».

Now we mark the points that talk about automatic receipt everyone necessary settings. If they are already there, choose others and return them to their place.

This solution helped in the early Windows versions The maximum, although in latest builds this is not observed.

Of course, sometimes they can appear individual problems. For example, when a window with error 651 appears during a connection. In this case, you need to check all connections and settings.

If you suddenly don’t understand something, you can always find a video that shows everything in detail.

I hope you find all the answers you need here. Subscribe to always know what to do with your computer.
