Joe, re: "Go to System Preferences > Network and in the left hand pane of the Network window select Wi-Fi, then click on the Advanced button near the bottom right of that window. The at the top of the Wi-Fi window select the Wi-Fi tab. this will reveal a list of Preferred Networks and what security, such as WPA2, WPA2 Personal, or WEP is enabled on each."
In the left hand pane there is Ethernet/connected and AirPort/connected. No Wi-Fi.
Under "advanced" there is a row of tabs:
TCP/IP, DNS, INS, 802.1X, Proxies, Ethernet
The same row of tabs appears whether I click on Ethernet or AirPort in the l/hand panel.
