To view the detailed information about the wireless networks in the Airport menu (hidden by default), hold down the option key while clicking the AirPort menu icon in the menu bar. The detailed information below the name of the connected network is:

  • MAC address of the wireless station
  • Channel is in use
  • Signal strength, RSSI, the lower it is, the weaker the connection
  • Indication of the data transmission rate

On hovering the mouse over the network name for a second, a tool tip displays the network’s signal strength and the type of security it’s using. This is useful for quickly finding the public connection with the strongest signal.
