Almost all modern gadgets can be connected to wifi-networks. This makes it possible to use the convenience of the Internet at high speed almost everywhere. There is an opinion that this applies only to small devices such as a tablet, phone or laptop (printer, camera, etc.). Many users are interested in the question of how to connect a computer to wifi, is it difficult, and what devices may be needed for this.

A stationary computer is therefore called stationary, which implies the summing up of all communications to it through various wires to a “permanent place of residence”. The PC can be moved further to another place, but this requires a major revision of cable routing routes, finding sockets, etc.

A novelty in recent years has been the emergence of wireless networks, thanks to which even a PC can be connected to the Internet using wifi technology.

Below we will figure out what is needed for this and in what order it is recommended to connect the desktop computer to the Internet “without wires”.

The layout of the article will be as follows:

Necessary equipment:

• External wifi receivers;
• Internal;
• Router.

Installing devices on a computer and configuring them:

• External receiver;
• Interior;
• Router.

Necessary equipment

Since the PC in most cases lacks the ability to find and connect to wireless networks, you first need to take care of acquiring equipment that will give it such privileges. Consider in detail how it happens.

External wifi receivers

Such devices look a lot like a large USB flash drive: they are small gadgets with a USB plug at one of the ends (see figure 1). In addition, they may have a small antenna, which allows to increase the "collected" signal.

Pic1 External adapter   (network card) Wifi from Tp-Link.

This device for connecting a PC to a wireless network is quite inexpensive (can be purchased for 10-20 USD). After the purchase, it will remain to connect it to the computer via USB, install the driver from the supplied disk, make the simplest settings and connect to wifi. We will consider all these operations in detail after we get acquainted with another type of wireless network adapter.

Internal (built-in) wifi receivers

Their name comes from the fact that they are embedded inside system unit   PC. To connect to the "motherboard" using the PCI interface, through which they are connected to a special connector.

rice 2 Internal receiver (adapter) wifi.

These devices do not differ much in price from external ones, and their installation on a computer also does not take much time and should not cause any particular difficulties.

So what type of adapter to choose? External or internal?

• An external one can quickly disconnect and connect to another PC;
• Internal receiver will not take free place   on the table; in addition, it is less susceptible to damage, since it cannot be touched by the user.

The choice is yours.

Router (router)

The wifi receiver can connect the computer to the network only if it can “reach” it. In other words, the source of the signal must be in range - the router.

fig.3 TP-LINK router   AC1750

It receives a signal from the provider via an Ethernet cable, passes it through itself and "distributes" it to wireless devices (including to a computer). Routers are more versatile and easy to use than access points. They allow you to simultaneously connect multiple gadgets (laptop, tablet, smartphone, PC ...) to the same network.

Equipment connection

We turn to the promised description of the installation process of the receiver wi-fi for a stationary computer.

External wireless adapter - installation and configuration

As an example, take the proven model of a reliable receiver model TP-LINK TL-WN721N. It can be purchased for 13-18 USD, and it is ideal for Windows 7. In addition, it supports all types of data encryption, and you can quickly create a connection. The maximum signal reception speed is 150 Mbps.

rice 4 External network card wifi TP-LINK TL-WN721N.

Step 1

We take the device out of the box and carefully study the package, which should include:

• The receiver itself;
• USB-cable (you can connect through it and use as an extension cord when looking for the best signal);
• Instructions in several languages;
• Disk with drivers.

Step 2

We connect the adapter to the PC directly, or via an extension cord (it can amplify the signal, acting as an additional antenna) to the USB port. Next, ignore any messages about successful installation   device drivers. They need to be independently delivered from a special disk that we found in the receiver box.

Step 3

We insert a driver disk into the computer, and then run the installation wizard. In the program that opens, select our model and click "Install driver and utility" (see figure 5)

fig.6 Installer dialog box.

During the installation, the following messages may appear (Fig.7 and Fig.8):

rice 7 Notification in a 32-bit system about the impossibility of installing the utility. It's not scary, so feel free to click "Yes."

rice 8 Windows 7 security can warn you about an unknown driver manufacturer. This is also not critical, click "Install anyway ..."

After a minute or two, the process will be completed, and such an icon can be found on the taskbar (see figure 9). It signals that the receiver is ready to connect the computer to wifi.

rice 9 Icon indicating the presence of wireless networks in range of the receiver.

Step 4

Now, when the adapter is ready to connect the Internet to the computer, it remains to click on that icon and select the appropriate wifi network.

fig.10 Selecting the desired network in the list of available connections.

And then enter the password (security key) and click OK.

fig.11 Specifying the network security key (password).

Everything. Now your computer is connected to the network via an external wifi receiver. You can start using the Internet.

Now go to the next chapter of the article.

Installing the internal wireless adapter

Step 1

For example, take the model TP-Link TL-WN751ND (approximate price - $ 15).

We take the device out of the box and unscrew the antenna if it is connected to the module (Fig. 12), since it will not be possible to install it into the system unit.

fig.12 Separation of the antenna from the network adapter (by unscrewing).

Step 2

Open the lid of the system unit and look for a slot for the wifi module on motherboard   (one of the PCI slots through which you can connect a wifi receiver, usually located below, under sound card) (see figure 13)

fig.13 Slot for the adapter on the computer motherboard.

We connect and, after re-screwing the antenna, we get something like this:

Fig.14 Ready for setting the built-in wifi module at your workplace.

Step 3

Setting up an internal wifi card is no different from setting up an external one: you first need to “install” the driver, then find the network and connect a computer to it. We reviewed these steps in detail in the previous chapter.

Install and configure the router

For example, let us analyze the process on the model TP-Link TL-WR841N.

fig.15 TP-Link TL-WR841N.

Step 1

First you need to connect the router to the computer through which it will be configured. Figure 16 shows the connectors through which the router is installed (blue for power supply; red for the Internet wire entering the apartment; green for connecting to the main PC, from which the network will be managed).

fig.16 back side of the router with connectors.

Step 2

Go to the web interface of the router.

fig.17 enter the ip-address to enter the settings of the router.

To do this, in the browser, in the address bar, enter the ip-address of the router with the http: // prefix (as in Figure 17). This "set" of numbers is different. It can be read where it will be specified by the manufacturer in 99% of cases - on the back of the device.

Step 3

Enter a username / password pair. In 90% of cases, this is admin / admin.

Step 4

Once in the settings, look for the “Network” tab, and in it “WAN”. Here you need to specify the type of network. To determine which connection is suitable in your case, you can consult with the provider. Click "Save" and go on.

Step 5

Go to the “MAC Clone” (ibid., In the “Network”) and click on the “Clone MAC Address”, after which we save the changes again (save).

Step 6

Go to “Wireles”\u003e “Wireless Settings”, where we enter all the values ​​as shown in the figure below. The only thing you can think of is the name of the network and indicate your real region. Do not forget to persist.

Step 7

Now go to the tab "Security" (Security). Specify the type of encryption and its algorithm as in the screenshot (you can just fill in everything the same way as in the image above). And, most importantly, create your own password for the network created.

Again we save all changes and complete the installation of the router by rebooting. To do this, look for the tab "System Tools"\u003e "Reboot", in which we press the single button "reload".

This completes the router setup process. Now you can bring to the computer on which you installed the wifi receiver wireless Internet. You need to go through that PC to “Available Connections” (as mentioned above), select the created network and connect to it.
