For a decade (!!), I've been writing and revising a book on using Apple's Wi-Fi routers. Long ago it was Take Control of Your 802.11b AirPort Network, and the current, fifth edition has the moniker Take Control of Your Apple Wi-Fi Network. This latest update (a bit late and all my fault for that) brings the title up to date for 802.11ac, the newest and fastest flavor of Wi-Fi, as well as OS X Mavericks, iOS 7, and Windows 8.1.
The book's designed for any home or small-business user who finds that the basic information Apple provides isn't enough. While I fully agree configuration has never been better for Apple's AirPort Extreme, AirPort Express, and Time Capsule base stations, if you want to configure network layouts or network details outside of quite standard arrangements, you might feel at sea. This book is designed to help.
I go through how to set up basic networks and more advanced ones, including creates pods of Ethernet-connected or Wi-Fi–linked base stations (and mixed groups), as well as walking through all the networking settings and how to use them for specific tasks. I fully explain the ins and outs of AirPort Utility both for OS X and the similar, but more limited iOS version. And I tell you how you can make the Eye of Sauron appear on your Mac.
For instance, you can choose a static, unchanging local address for any computer or device on your network through DHCP Reservations. It's several steps with a few choices, and I take you through that. The book also explains frequency channels and the various Wi-Fi/802.11 standards, and how to site your equipment ideally and troubleshoot it when it doesn't work.
For more details on the book—which is available in DRM-free PDF, EPUB, and MOBI that you can use anywhere without restriction—and a downloadable excerpt, visit the Take Control page. At $20, it could save you an amount of frustration you can't stick a price tag on.
