I am using aircrack-ng 1.2 rc4 on windows 7. Is there a command to ask airodump-ng which of my wifi adapters it recognizes ?
I tried airodump-ng wlan0
and received Adapter <wlan0> not supported
You need an RTL8187 based adapter or an Alfa AWUS036AC - Both these realtek based USB adapters have been the best I have used. Some Atheros chipsets work but I always get poor range when using those, but not the realtek.
Another point is that Windows does a very, very poor job with aircrack-ng. Get hold of the Kali linux distribution and install - Everything is installed ready for you to start experimenting.
