Thank you WCNA for your time and your info !
I just want to let you know,that i don't intend to use any of these info for illegal purposes. Is just for my research paper and it goes only that far, and that's it !
I want to know what ways are out there to penetrate an wireless network and how to cover you tracks just for the reason of finding new ways to protect and defend an wireless network and new ways to track down the bad guys, so to do that i have to first understand and know the other side. The network which i'm gonna apply all these techniques and try to attack is the one of my university, which by the way i have already been given the permission to do so by my teachers. Thus, there's nothing illegal.....

I'm gonna use this info wisely and I'm also on the side of the good guys !! So again thanks a lot my friend!!
