Yep, I agree 100% with iTpHo3NiX and proxx
One more time I will explain why.
The famed Alfa cards do work good for basic wifi attacks such as cracking WEP and grabbing handshakes. However that is about all they can seem to handle, or I have bought about 6 shitty ones in a row.
If you try to use the card for anything more demanding such as streaming video, downloading shit, etc It will overheat and the connection will take a shit.
I have had times where I was able to get into networks but when I try to connect to it with that card it will be so slow that you cannot hardly do anything at all. Yet others can handle it fine.
Have also had a time where I tried to use it for MITM/fake AP attacks and as soon as the victim starts to actually use the internet it freezes up and looses the whole thing.
Fuck that shitty ass card. I'm pretty sure it is the drivers more than the card itself, but all the same in the end.
