The answer to that question might depend on the operating system on
which you're running.
You never explicitly said what operating system you're using; however...

...given that you mentioned iwconfig, I shall infer that it is some
version of some Linux distribution.
http://www.ethereal.com/faq.html#q4.21
gives information on how to capture raw 802.11 packets. The page at
http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Linux.Wireless.drivers.html
indicates that Wavelan cards are Orinoco cards; unfortunately, the patch
listed in the Ethereal FAQ for one of the drivers for those cards
doesn't work with all versions of the firmware for those cards.
(I do not have any 802.11 hardware, so there are limits on how much more
help I can provide. You should ask the developer of the driver for your
wireless card, or some Linux mailing list, for further help.)
