Gizmodo reports that many owners of the new 2013 MacBook Air are complaining of lost Wi-Fi connectivity, requiring a reboot to reestablish the connection. The issue is reportedly worse when the MacBook Air is on a desk, which might indicate a hardware issue. So, if you’re thinking of buying a new MacBook Air for its significantly improved battery life, perhaps hold off until more is known about this Wi-Fi issue. follow link
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.
