The Linux kernel supports a large number of network adapters. To this day maintenance of various wireless devices is greatly improved. This applies to both the Wi-Fi adapters and the PCI Wi-Fi card. But all these different devices have different performance and functionality. Every user wants to have a Wi-Fi adapter high power and at the lowest possible price. Furthermore, they are looking to wireless devices with a variety of additional arrangements required for testing the safety of the networks. Let's look at the best Wi-Fi adapters operating system Kali Linux in early 2017. Naturally, they are also suitable for any other Linux distribution.
How to choose the most appropriate Wi-Fi adapter
Most Web sites recommend adapter AWUS036H. This is an excellent decision, but it was in the past. This card is already old, does not support modern standards, its speed of operation is only 54 Mb and maintained only b, and g standards and new technology n is not supported. And if you just select your adapter, you can get a device that is not fully supported. It is not enough only the name of the adapter, more important is the chip used in it. Ie it determines the overall maintenance of the Linux kernel.
Here chips that work best:Atheros AR9271 - IEEE 802.11B / G / N
Ralink RT3070 - IEEE 802.11B / G / N
Ralink RT3572 - IEEE 802.11B / G / N
Realtek RTL8187L - IEEE 802.11B / G
