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.

Disclaimer -- As some of you may have noticed, I now write the Beating the System column for MacUser. I don't know what to disclaim, but since I'm identified as the editor of TidBITS at the end of those columns, it seems only right to mention it here. Writing for MacUser is different in that I have an approximately four month deadline for MacUser and a one hour deadline for TidBITS. That said, check it out and see what you think of my writing when I have a word limit and a professional editor.
