I was told that my wireless card (Atheros AR5009 otherwise known ath9k) would be able to inject packets without the need for patching if I were using Ubuntu version 9.10 or above. (Is this true?) I'm currently running Ubuntu 10.10 and I'm trying to find a tutorial that would help me with WEP recovery.

What I found is

But it seems very outdated since in the tutorial, the author is using madwifi which I don't have.

Does anyone know a video or tutorial on this subject with my or similar driver?
