In the blog post just above this one, you should see a download link for the previous edition of this ebook. The previous edition pretty much covers the same Apple gear and operating systems, but it describes an older version of AirPort Utility. However, if you are working with older gear and older computers, you may need older advice. To that end, you may download two even older ebooks that focus on the older base stations and that were last updated some time ago—they are frozen in time with older versions of Mac OS X. The two older ebooks are:

• Take Control of Your AirPort Network: This is the first of Glenn's AirPort-related ebooks. It describes networking with 802.11b and 802.11g gear, and its descriptions of Mac OS X are from before 10.5 Leopard.

• Take Control of Your 802.11n AirPort Network (first edition, version 1.6): This is the second of Glenn's AirPort-related ebooks. Last updated in 2009, this ebook covers the simultaneous dual-band 802.11n base stations that Apple released in 2009. Although its core focus is on 802.11n, it also covers scenarios where you are using 802.11b and 802.11g gear, or where you are mixing older and newer base stations on the same wireless network. It's primary Mac OS X focus is on 10.4 Tiger, 10.5 Leopard, and 10.6 Snow Leopard.
