I have an eMac G4. Nothing special but I love it. I have an original Airport base station. Unfortunately my old Airport Cards will not work in my mac, it has to have the Airport Extreme card. I have to have wireless, I used my DSL connection for my X-Box 360 and my eMac. What would be the cheapest card I could get that would work for my eMac? I don't "have" to have an Apple card. What are some of my options?
