Wireshark-users: [Wireshark-users] cracking wep with wireshark/ AirPcap

I just got my AirPcap in the mail and with only ten minutes to use it today it seems to work great. Im tryin to absorbe as much as I can about data analysis and wireshark features and still have alot to learn.

   I am interested in trying to crack the WEP on my WLAN and looking for any advise or direction. I am familiar with Aeropeek and Aircrack somewhat but have never been able to use them do to incompatability with my Dell wireless card.

   I am simply interested in passively capturing the necessary packets on my WLAN without any injection or authentication type attacks. My understanding is that I have to capture enough IVs and then use something like Aircrack to calculate the WEP key.

    Has anyone attempted this using Wireshark?  Can it be done? What programs do you use to calculate the WEP key?  Is there a filter for just the ivs? Im using WinXP. I do have access and some knowledge of Ubuntu and Knoppix but still learning and would like to keep this Windows based for now.
(Btw...I have the latest Ethereal/ wireshark book in the mail from Amazon)

Thanks
Dave
