followed the instructions on here but the last command fails. I have tried getting aircrack to run diff way by following this lil guide http://www.aircrack-ng.org/doku.php?id=simple_wep_crack but after a few steps, it turns out I need to download/install wifi drivers.

All in all this app could be useful if more info was provided on it. Its easy for folk who know of it and have been using it in the past on other devices etc....but for new newbies its like running into a brick wall!

If anyone can help or provide some further info that can help then it will be appreciated
