I have a netgear wireless router connected to a iMac #1. I have an Airport Express card installed in imac #2. (By the way, when you stick in the airport card, how hard are you supposed to push? I had to cautiously push hard until I heard a tiny click. Is that it?) So my imac#1 is hard-wired to the router, and it gets 170kb/s. My imac#2, roughly forty feet away from the router, only gets 30kb/s. Do you intelligent people think it's the router or the airport card? I just can't deal with the fact that my eleven year old sister is getting almost 6x the speed I'm getting and I'm the computer guy.
