WiFi receivers and everything about them

WiFi receivers are already so tightly integrated into our lives that it's hard to imagine without it. Almost all laptops and smartphones are equipped with this device. With it, you can easily and easily connect to wireless networks.

Execution

In its execution, WiFi receivers are of the following types:

• integrated;
• interior;
• external.

In the first case it is made in the form of a separate chip and soldered into the motherboard. Most often in such a performance, such devices can be found on inexpensive motherboards, smartphones and netbooks.

The second option is internal. It does not happen so often. This is a board that is installed in the PCI expansion slot on the motherboard.

In the latter case, this device is made in a separate case and resembles a flash drive. Connects to a regular rectangular connector USS such a WiFi-receiver. The price for each of the variants is different. An integrated adapter, for example, does not need to be bought. It comes with a digital device. But comparing internal and external, we can conclude that the latter is much less. The prices for such devices start from 150 rubles. In turn, the cost of internal adapters starts from 400 rubles.

At the same time, their characteristics are identical. Another classification of such devices is based on the standard with which this wireless adapter can work. In this case, they are subdivided as follows:

• 802.11a - data transfer rate 54 Mbit / s, working frequency 5GHz.
• 802.11b - in this case, the data transfer rate is up to 11 Mbit / s with the same frequency, but the range of this wireless network is increased to 150 meters in open terrain.
• 802.11g - this standard appeared 4 years after the first two in 2003. His speed is the same as "a", and the range is twice that of "b". It is backwards compatible with the previous two standards.
• 802.11n - has become a logical development of the "g". It has both the data transfer rate increased (up to 600 Mbit / s), and the range has increased (up to 600 meters).
• The last standard - 802.11ac - has not yet received much distribution. The main difference from "n" is the increased data transfer speed, which in this case can reach phenomenal 10 Gbit / s.

Connectivity

For an integrated Wi-Fi adapter, this step is skipped. The internal receiver is installed in the expansion slot of the motherboard. To connect it, you need to remove the side panel from the system unit, install it in the white PCI slot. There can be several. It is better for these purposes to use the one with the serial number "1" (if it is free). Further, the Wi-Fi adapter board must be fixed with a bolt, which is screwed to the body of the system unit. At the next stage, the computer assembles and returns to its original state. All described manipulations should be done only with the equipment on. In case you need to connect WiFi receivers in an external version, you do not need to turn off the computer or laptop. It is enough to find the right rectangular connector and install the adapter in it. For stationary PCs, it is recommended that you use the jacks of the USS, which are pulled to the rear of it and soldered into the motherboard.

Customize

The next step is to programmatically configure the WiFi receiver for a PC or laptop. First you need to install the drivers. When you connect a new device, the software is searched for, which is necessary for its normal operation. At the end of this operation, you should see a message stating that the equipment is installed and ready to work. But if the necessary software is not found, a message will appear that the operating system did not find it. In this case, you need to install it manually. A CD is included with each adapter. On it there is a necessary driver without fail. If the disk is lost, then the necessary information can be downloaded from the official website of the manufacturer. Then run the installation version of this software and, following the instructions of the wizard, install it on your local computer or laptop. Then a gray ladder should appear in the lower right corner of the monitor. We click on it with the left mouse button. In the opened list we find the necessary wireless network and connect to it. If necessary, we enter a password to gain access.

Test

At the final stage, you need to verify that the installed connection is working on WiFi. The receiver for the computer is also configured properly. To check, you need to run any browser that is on your computer (for example, Microsoft Explorer or Opera). Then enter the address mail.ru in its address bar and click "Enter". After that, this portal should open. Another nuance that you should pay attention to during the configuration: the mode of operation of the router and the Wai-Fay transmitter must be the same. For example, if one of them is set to "b" and the other "n", data transmission will not be possible. Although wireless networks in the list of available connections will be present.

Conclusion

Within the framework of this material, various modifications of such devices as WiFi receivers have been described. The order of their connection, adjustment and testing is also indicated. All this will allow to configure such equipment without any problems to any user, regardless of the level of his training and knowledge. So we take it boldly and do it. Problems should not arise.
