Cracking via weak packets is broken on the current version of Kismac.
If you save your Kismac dump files you can use a tool like aircrack
(http://www.cr0.net:8040/code/network/) to crack the WEP key for a
specific BSSID. While the aircrack toolset was designed for Linux, the
aircrack and 802ether applications compile and work under MacOS X just
In my tests I was able to crack a 128-bit WEP key after capturing about 500,000 encrypted packets. Notice I didn't say weak packets as aircrack doesn't depend on "weak" packets, only packets with unique IVs.
I've posted version 2.0 of Aircrack compiled for MacOSX at http://www.macunix.net/Aircrack-2.0_MacOSX.zip
Please see the readme file on how to use aircrack.

That's a hard one. Anywhere from 10 to 10,000 depending on how weak the weak packets are, and if the same weakness is through out them. Even after a day or two monitoring my own network (which is heavily used) I still was unable to crack my wep. I had something like 15,000 weak packets.

Why everytime I try any crack method (bruteforce or others), it says that
there are not enough packets?
What is the minimum packets?
