Cameron Kaiser is a recovering database administrator and programmer who unwisely got an MD instead and now works as a county health physician in Southern California. He drives old United States highways, maintains old Commodore and Apple computers, and relentlessly implements old information technologies on his "$50 Wal-Mart server rack" in his rapidly disappearing spare time. He has used Macs since 1987 except for a brief stint we shall not talk about.
Viewing Wi-Fi Details in Snow Leopard
In Snow Leopard, hold down the Option key before clicking the AirPort menu. Doing so reveals additional technical details including which standards, speeds, and frequencies you're using to connect, as well as what's in use by other networks. With the Option key held down and with a network already joined, the AirPort menu reveals seven pieces of information: the PHY Mode, the MAC (Media Access Control) address, the channel and band in use, the security method that's in use, the RSSI (Received Signal Strength Indication) measurement, the transmit rate, and the MCS Index. In Leopard, some, but not all, of these details are revealed by Option-clicking the AirPort menu.
