Intel's mini2100 is the wireless component of the Centrino chipset, there is no native Linux driver right now... Blame Intel, they're not being forthcoming with how the thing works enough for anyone to be able to bang out a driver.
Pick your distro, compile the ndiswrapper from:
ndiswrapper.sourceforge.net
or install the driverloader:

Just make certain your kernel source code is installed, the drivers just need it for the compile.
