Hi, i recently bought this for my old G4: http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=3246388&CatId=2697 Airport cards are pricey and costs half as much as my system's total street value. I installed it along with the accompanying driver this morning and while my mac recognizes the card exists, I can't seem to find any software that works with it to search for wi-fi connections. I tried istumbler but it only seems to work with airport specific cards. Any ideas? Thanks.
