How to choose an external wireless wi-fi adapter for a computer
Today, in the world, various gadgets are produced, which have the function of accessing the Internet using wireless networks. But still, there are devices that do not provide the ability to use Wifi - personal computers. Therefore, the owners of this type of computer have the task of eliminating this problem. Wireless Wi-Fi adapters come to the rescue.
What is a Wi-Fi adapter
A Wifi adapter is designed to receive a signal from an access point and transmit it to a personal computer. Such a device is needed only in cases where the computer cannot independently receive a signal. At the moment, there are two types of adapters: the first one only receives a signal from the router and transmits it to the computer, the second one is able not only to receive, but also to create its own access point on the computer. They also differ in location: external and internal.
How to choose a wi-fi adapter for a computer
When choosing such a device, you need to take into account many factors: from your ability to work with a computer, to the speed of the Internet. Wi-Fi adapters that connect via a USB port are very popular. They are very easy to operate and do not cause much inconvenience to users.
There is another type of adapter connection to a computer - via PCI-E. This method is complicated from a technical point of view, for it you need to know if the computer has a connector for connection.
The most important parameter when choosing a Wifi adapter is the Wifi wireless network standard. The most common standard is 802.11n. It has good signal quality and acceptable frequency. It also allows you to transmit wirelessly the Internet, the speed of which reaches 300 Mbps.
You need to pay attention to the power of the Internet receiver that you want to buy. If it is lower than 20 dBM, then such an adapter does not need to be bought, since it will not receive a signal from the router well, even if it is not far away.
If you do not care what kind of adapter it will be, it is recommended to buy it with an external antenna. This will improve the quality of signal reception, and ensure a stable connection of the computer to the Internet.
After purchasing the adapter, you need to connect it to your computer. After that, you need to configure it and install the necessary device drivers. They are taken from the disk that comes with the kit.
In fact, installing and choosing a Wifi adapter does not cause any difficulties for many users. For a good data transfer to a personal computer, you just need to choose an adapter that matches the characteristics of the router and computer, and install all the necessary software, following the instructions that come with the device.
