Hello guys,

I'm using VirtualBox and having Kali Linux as guest. It took me 5-6 hours to even make use of my AC1200 USB Wireless Adapter AWUS036AC. Before finding the solution it would only show me the USB Adapter as connected via USB but I would not be able to see any networks, nor would iwconfig show me my card.

I followed following instructions to make it work:

Re: Compiling RTL8821AU Wifi USB adapter failure (Compile make driver error: 2)
It's a known bug. https://bugs.launchpad.net/ubuntu/+s...u/+bug/1625097

Code:
sudo apt update
sudo apt install git
git clone https://github.com/diederikdehaas/rtl8812AU.git
cd rtl8812AU
make
sudo make install
sudo modprobe 8812au



After following these steps it would show me the card in iwconfig and it works.
However when trying to change its MAC-Address it won't change it bringing following Message: Network driver didn't actually change to the new MAC!!

I used:

ifconfig wlan0 down
macchanger -r wlan0



After having so much troubles even making this USB wlan Adapter work on Kali Linux it seems it still doesn't work properly. Are there any ideas on how I can get this to work or how I can give you guys better information to solve this?


@EDIT:

It seems that my card is not working properly on the guest (It does work properly on the win7 host though). I tried connecting to my WLAN but even with correct password it won't properly connect.
Any ideas on driver installation or other stuff? I'm helpless and I have searched so many hours already...

So bridge the network and use it.
You just wont able to run your automate wireless cracker on your neighbors wifi networks.
You could try installing Kali ( hehehehehe ) on your hardware, that might make it easier, or it might turn your laptop into a brick... it's hard to say.
Course worse things could happen. You don't know this but the MAC address you're trying to spoof is not hidden on the packets outside the virtual network so... you can get caught very easily and busted if you bump into the wrong wifi network.
What you're trying to do isn't a game to a lot of people... the FBI for example.

your not supposed to change the mac address of your lan card, it's called "being in permiscuous mode" and in some areas it's illegal to do it (except for legitimate / testing reasons) - also check your telephone company agreement (i doubt they allow it either)

the only need for doing it would be to deceive others - any other need and the nic card manufacturer would gladly exchange your nic card for you (ie, if they gave you two using the same mac - likely impossible)

if it can't change? well perhaps changing it isn't supported for that card by the software (or driver) your using
