When installing 12.04, I didn't have any wireless network, or at least none that I could see at the time. I then asked a question here, on askubuntu. Someone for which I am grateful replied and gave me a solution. For some reason, however, aircrack doesn't work with it.
Now I get to my question: How can I have wireless drivers and aircrack working? [With the answer being in terms of command-line code and/or debian package installation]
