Del manual :
It really depends on your luck and the way the IVs are distributed. Most of the time, one million unique IVs (thus ~2M packets) are enough. If you're very lucky only 500K IVs may be required; and if you're out of luck you could need around 1.5M-2M unique IVs.

I've got x million IVs but aircrack doesn't find the key.

WEP cracking is not an exact science. Sometimes luck is on your side, and sometimes not. By gathering as many encrypted packets as possible, you'll greatly increase your chances of finding the key. Also, raising the fudge factor might help.

Y lo que te "rondará moreno",NO es una ciencia exacta,hace lo que puede,los milagros Dios.......hi hi hi.
