Getting Alfa AWUS036ACH up and running on Kali

Last night, I finally got my Alfa AWUS036ACH up and rolling on Kali 2019.4 running in Virtualbox.

Here's a very short how-to:

• Plug in your NIC
• Open the settings for your Kali VM
  • Go to "Ports" => "USB"; Select "USB 3.0"
  • Click the Icon with a plus-sign on it, and add the "Realtek 802.11n NIC" filter
• Start your Kali VM
• Run git clone -b v5.6.4.2 https://github.com/aircrack-ng/rtl8812au.git to clone drivers from the aircrack-ng project for the rtl8812au-chipset, and navigate into the folder using cd rtl8812au
• Run sudo ./dkms-install.sh to install the driver via dkms.

That was it.

For more information, check the README for the driver.
