pfSense 2.0.3 doesn't recognize my wifi card

Hey guys,

So I recently gave new life to an old desktop as a pfsense box, however I am having quite a few problems. Most noteably the box is not relizing that I have a wifi card installed so I can't make it an access point which is what I'm trying to do. Also I am having problems with the webconfigurer, every so often my browser (firefox) will say that it can not reach te address becasue it has either timed out or is taking to long.

I am not very strong in the software end of computers so all of this is baffling to me, any help would be very appreciated.

Thanks
