Be sure that your wireless card is supported. If it is, you need to set up your wireless network with iwconfig (the wireless tools for linux can be found here:
http://www.hpl.hp.com/personal/Jean_...nux/Tools.html).
If it's not supported, you can check ndiswrapper:
http://ndiswrapper.sf.net. I have no experiance with it, though.
Read the documentation. Pretty much, it will go something like this:
iwconfig essid <your_network's_ssid> mode managed [or ad-hoc, if you are] key <your_key, be it 26 digit MD5 (128 bit) or 40 bit>
then bring up your internet in whichever way FC2 does it (I use debian, with me it's ifup eth1 [eth0 being my land-line ethernet card]).
Hope that helps!
