Just a quick note to let you know that this issue of TidBITS is going out to exactly 40,000 people on our mailing list. Our list goes up significantly each day (between 50 and 100 people), although we also delete several hundred people each week due to mail problems. Still, we've been hovering around this 40,000 point for a few months and it's nice to achieve it finally. [ACE]
Option-Click AirPort Menu for Network Details
If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.
