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
git clone -b v126.96.36.199 https://github.com/aircrack-ng/rtl8812au.gitto clone drivers from the aircrack-ng project for the rtl8812au-chipset, and navigate into the folder using
sudo ./dkms-install.shto install the driver via
That was it.
For more information, check the README for the driver.
