I just bought a new mac book pro i5, this is my first mac and I know I'm going to love it but right now i'm getting frustrated with it. My current problem is: I have a wireless external hard drive that is connected to my cisco wifi box. I have my two desktops and other laptop connected to the the external hard drive through the network (no wires), but I can't figure out how to get this mac to connect to it. Please Help!!!
