Hello

I've just bought an Alfa AWUS036NH and installed RT3070 drivers on my virtual machine Kali.

ifconfig :
Code:
root@kali:~# ifconfig wlan0

And when I try a Iwlist wlan0 scanning, it just says "No scan results".

My wifi card works good in my host system (Win8.1/64bits)...

I appreciate your help, I'm lost...
