Google the name of your wireless cards brand and model and append the word linux and/or ubuntu. Ubuntu may actually have detected your card and have a "restricted" driver you can use for it; if it doesn't, either prepare to compile your own driver, use NDISwrapper, or just not use that adatpter to get on the internet with your machine.
I could link a ton of stuff for you, but it wouldn't help you in the long run. The Ubuntu team did a great job at bring *nix to the end user, but it is the responablity of the user to configure the machine properly, just as it is with any *nix operating system.
As much as I hate the Ubuntu moderating staff, consider joining the ubuntu forums; search for your answer there, and if you STILL can't find it, download a list of cards that will actually work (but seriously, if you're going this far, it shows you probably didn't look at the cards that work fine with NDISwrapper {google, NDISwrapper list}).
Look, no offense, but you're trying to run windows executables on a *nix system and wondering why it wont work; you should consider getting some education on how to use a unix like system; there are many books out there, free or not. For better or worse, one of the main reasons I hate linux forums is the seemly endless amount of arrogance that spills from them; but I realize that I can't blame everyone for the fualt of a few. Linux forums expect you to at least do some of the research on your own, and educate yourself frequently, you have to want to learn. One book I can recommend for that is A Practical Guide to Linux(R) Commands, Editors, and Shell Programming by Mark Sobell. The same author also makes a book directed at Ubuntu users and uses a relatively new ubuntu distro.
