Alfa AWUS036ACH Setup

The Alfa AWUS036ACH card works for 2.4GHz and 5.0GHz and is listed as good for hacking. Seems to work fine.

Drivers

When passing through to kali you need to download drivers. Was Plug-and-Play in Windows.

sudo apt update
sudo apt install realtek-rtl88xxau-dkms

Watch the output of the above. Seems to work in 2019 kali distros, but not 2020 due to missing linux headers.

sudo apt-get install linux-headers-$(uname -r) 

If the above doesnt work for your distro (didn't for me), you will need to do it manually. Looking at the output of the above should tell you what it is attempting to find (such as linux-headers-5.9.0-kali2-amd64).

Go to this URL:

http://mirror.internode.on.net/pub/kali/pool/main/l/linux/mirror.internode.on.net

Search for the package that you want, download it and save it and then install it.

sudo dpkg -i linux-headers-5.9.0-kali2-amd64_5.9.6-1kali1_amd64.deb

Your package name will be different based on version.

This failed for me because of missing dependencies, so i used the following to remove the package.

sudo apt --fix-broken install

I then downloaded the dependancies i could.

sudo apt install linux-kbuild-5.9
sudo apt install linux-compiler-gcc-10-x86

Then go back to the webpage above and download any other packages missing. For me that was the package linux-headers-5.9.0-kali2-common

Install it.

sudo dpkg -i linux-headers-5.9.0-kali2-common_5.9.6-1kali1_all.deb

Now with all the dependancies sorted (you may have other ones to fix), I installed the package again.

sudo dpkg -i linux-headers-5.9.0-kali2-amd64_5.9.6-1kali1_amd64.deb

Now I can pass the WiFi card through to the vm and see wlan0.

sudo iwconfig 
eth0
lo
wlan0
