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.

 
 

Take Control News: All About 802.11n AirPort Extreme Networking

Send Article to a Friend

We have one last announcement for you before we turn our attention to Leopard - free updates to both "Take Control of Your 802.11n AirPort Extreme Network" 1.1 and "Take Control of Your Wi-Fi Security" 1.5. These aren't piddly little updates either; Glenn added 17 pages to the former, and we bumped the latter all the way to version 1.5 because of the many subtle changes throughout.

The AirPort Extreme Base Station may lack the pop-culture cachet of the iPod, but we've heard rumblings that it's the best-selling 802.11n-savvy wireless gateway on the market. Good though it is, setting up an 802.11n network has challenges: integrating legacy devices, attaching hard drives and printers, configuring Internet connections, and so on. Glenn Fleishman, widely acknowledged as the Mac world's Wi-Fi expert, tackles all these topics and more in "Take Control of Your 802.11n AirPort Extreme Network," making this book essential for anyone relying on either of Apple's two 802.11n-capable AirPort Extreme base stations. Glenn even added a section explaining how to build a network with two or more base stations, along with discussion of all the latest happenings in the wireless world.

Glenn has also been busy helping me update our book about one of the trickiest and most important aspects of wireless networking: security. Our "Take Control of Your Wi-Fi Security," in its first update since 2005, adds discussion of the iPhone throughout, looks at the sidejacking exploit, drives a few more nails in WEP's coffin, looks at easier security with Wi-Fi Protected Setup (WPS), talks about how to use an SSH proxy for security and anonymity, and explains how IPv6 eliminates NAT (which may or may not be good for security).

If you own the 1.0 version of either book, click Check for Updates on the cover to access your free update. And if you've just purchased one of Apple's new 802.11n-capable AirPort Extreme base stations, or if you've started to worry about your security, you can buy either book for $10, or both together for $17.50.
