I'm using Kali through VM Virtualbox, and I have a AWUS036H USB Adapter that I use for connection. Its MAC address can be spoofed just fine but it seems every time I disconnect from a wireless network, or just randomly while I'm connected, if I type ifconfig in the terminal my wlan0 adapter's MAC address has returned to its permanent hardware default. I do not know what is going on and this has happened multiple times in a row.
Also in the bottom-right toolbar for Virtualbox the circle over the USB icon keeps changing between green and red, and the light on my adapter when in use is usually flashing green. Are these normal?
