I have a desktop G5, 1st generation. Verizon DSL. My girlfriend comes by with her laptop and needs to be able to access the internet on her MacBook Pro. What do i need to do? Airport Extreme? Express? And do i need a card? I asked the guy at the Apple store and he just seemed so rushed when he answered me i don't even know if he really knew what i was asking. He said the Extreme. The access would be only for her laptop and my iPod Touch that is on it's way soon. Thanks for any help.
