wardriving question

[Jeremy R Brinkley]

I'm looking to do some wardriving. I have a cisco aironet 350 pcmcia card
and was wondering if I can capture raw packets in ethereal or ettercap. I'm
also looking for a good netstumbler type program that will work with this
card. I haven't found any decent ones. I'm considering buying an 802.11g
card. Are there any decent ones which have an external antenna connector
that are supported under freebsd?
