I have an acer travelmate 2450 and i have installed Leopard (kalyway 10.5.2 DVD) as my only operating system. Everything seems to be working, after alot of tweeking, except the wireless. I have tried many things and cannot get it to work. The problem is i don't know the exact wireless card in my laptop. All i know is it is some type of atheros wireless b/g card. If anyone could get my wireless working that would be great! Thanks!
