Take Control Books has released “Take Control of Your 802.11n AirPort Network, Third Edition” (http://tid.bl.it/your-80211n-airport-network) by networking expert Glenn Fleishman. The book is designed to help you ensure that your wireless network is fast and reliable.

The 187-page book is fully updated to cover the entirely revamped AirPort Utility 6, which runs only in Lion and later. The book — US$20 for the ebook, $34.99 for the print edition — also now discusses using AirPort Utility for iOS.

In “Take Control of Your 802.11n AirPort Network, Third Edition,” Fleishman provides real-world advice for configuring the 802.11n models of Apple’s AirPort Express, AirPort Extreme, and Time Capsule. It’s designed to be of assistance whether you’re setting up a simple AirPort network for the first time, replacing an older base station with a fancy new one, or adding additional base stations or devices to extend your network’s capabilities.
