Of course the articles written about such apps. I looked and didn't find any lack of information out there. As you didn't supply a country, I can't be specific and here, Hak5 had what I wanted.
I am looking for a wifi card that has a long range, supports Mac and Kali/Backtrack Linux (supporting windows would be nice but if not possible not going to worry) and suports packet injection so i can pen test wireless networks. It would also be nice for it to have a long range for war driving.
Has anyone got any suggestions?
