Hey, I remember seeing wifi hacking software, and other various types of different software and such. I do regret that I never spent the like 9 dollars in BTC to see if the software is legit or any good, REVIEWS MUCH APPRECIATED.. Thank you community.

These are what you are looking for but they only work in Linux and you have to have a compatible network card.
