Ok back ground information. I work for a small pizza place in the town that I live in. About a month ago we got hacked as we have a wireless router in the shop and a good few shop secrets have been stolen.
I started reading up on ethical hacking and wireless broadband as to learn more about the subject help out my boss and broaden my mind.
Since then I have worked my rear off to secure not only my home and work but also my wife family when it comes down to wireless broadband. I have noticed a gap in the market for personal wireless security and am now reading every piece of information that I can find on the subject so that I can pass this onto Joe Soap down the road and maybe create a small business out of it.
Ok question I have found a good bit of information on wardriving and was wondering what is a good express card that I can get for my laptop. I have a pavilion dv9500 which I am using or is there a wireless card that I can get that I can run on usb.
