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.

Send Article to a Friend

Google has used HTML5 and JavaScript to create a Web version of the famous Rubik’s Cube puzzle. Educator Ernő Rubik created the cube in the 1970s to teach his students about spatial geometry, and it became a commercial hit in the 1980s. You can fully rotate and manipulate Google’s virtual cube, and there are even a number of keyboard shortcuts.favicon follow link
