ALFA AWUS036ACH Driver Installer for Kali Linux (v1.2-dynamic)

This script installs the correct Realtek RTL8812AU driver for the ALFA AWUS036ACH USB Wi-Fi adapter using DKMS on Kali Linux (and Debian-based distros). It supports monitor mode, packet injection, and survives kernel upgrades via dkms autoinstall.

Tested on Kali Rolling with kernel versions 6.8 and above.
