Hey, I'm trying to crack my WEP key and its failing. I followed Xploitz's tutorial and it says I have 181,000 IVs but its not cracking it. I just used svn to checkout the lastest copy of aircrack-ng. I am running airodump to gather traffic, aireplay to generate more traffic using ARP mode and it says that it failed every time..

Can someone please help me with this?

Oh, and I'm on a MacBook Core Duo using Airport Extreme (Atheros chipset) for wifi.
