Just because it came with a cd doesn't mean you have to install it. I never installed the cd that came with my router, or my mouse, or most anything I buy. Its all crap that forces ICQ or something retarded on your computer when you don't want it.
So do you really have to install the cd?
Also you might see someone create a driver for the wifi adapter for other OS's soon. I sure hope so. Lazy Nintendo people, bah.
