I am changing all my passwords, and am really confused with the 3 Airport passwords vs our network. I have a password for the Airport base station, Airport extreme, and an Airport network password. Plus, I have a Network password. WTB? I have an iMac as a base, I guess you'd call it, and my wife has a laptop a few rooms away. The router, etc, are here w/ me. What are all these passwords for, and which one(s) does/do my wife need? Thanks for the help. John
