I recently just received my awus036ach and was successfully able to connect it and use it in Kali on my laptop. due to the fact that my laptop is slow , I wanted to try and connect it to my desktop It works fine on windows but as soon as I start Kali in Virtual Box it completely stops working on windows and VM. Yes its installed on virtualbox and it also shortly shows up as devices in kali but when I run ifconfig in terminal I dont see wlan0. Help please cause it worked fine on my laptop.
That’s the issue with Alpha adaptors, it sometimes works with kali and sometimes it doesn’t. From what I have read online and worked for other people was try reinstalling Atheros drivers.
apt remove firmware-atheros
apt install firmware-atheros
