Few days ago, I bought a USB Wi-Fi adapter to learn about pentesting. The goal was using this adapter to connect a virtual Kali Linux distribution in VirtualBox to Wi-Fi network through USB. After some hesitations, I picked up a cheap enough model which uses a RT18812AU chip. An important factor to choose this chip is that it is dual-band. This was the first time I’m dealing with such material. Of course, there was no such thing as plug-and-play.
