ethernet cable hook up ... ethernet cable from modem to airport,and ethernet from airport to mac ?
That would be correct if you don't want to use wireless on the Mac.
Ethernet connection from modem to WAN "O" port on the AirPort, then Ethernet connection from a LAN <-> port on the AirPort to the Ethernet port on the Mac.
Bob, great thank you, and G'day from Oz ...but wouldn't I be MAC wireless through AirPort, perhaps I have would not have access to MAC harddrive, but would see the AirPort hard drive ( and if I had additional portable harddrive pluged into AirPort )
Sorry, I am not following this. Are you asking about a Time Capsule?
