WEP cracking

I've always heard that WEP keys are easy to crack, and I was wondering if it would be possible to do so using some (very) old hardware I have lying around.  Specifically, all I have available is a SMC2632W PCMCIA card, a WUSB11 linksys usb network adapter, a quite old laptop, and a decent desktop. 

When I look at the software and information I can get from google, everything seems simple except capturing the traffic to analyze.  Are there any utilites (windows drivers or a linux build) compatible with my wireless card, or is it impossible?

Any help will be appreciated, thanks. 

you all are retarded.
just type the IP address of the router in the address bar.
it will ask for you to log in.
by default its admin for both the username & password.
then goto settings or security & it should be there. thats how i get free WiFi at Mcdonalds.
