The title says it all, and though I'm wary of anything branded as 'complete', Paul Heltzel's 'Complete Wireless Home Networking' offers both the essential education and the 'walkthrough' for you to start your first home wireless network.
The content is comprehensive; covering topics such as whether you should network wirelessly at all, to choosing network types, making product purchasing decisions, through to more technical topics such as choosing network architectures and actually building your network. It also covers security and troubleshooting.
This was published in 2003, and does discuss 802.11g. But it does not talk about any of the more recent 802.11 developments, including important improvements to wireless security, such as WPA. This kind of fast evolving technology can throw a publication out of date quickly - but the significance of this book is actually in what it does not cover. Wireless networking is a hot topic, and the World Wide Web spares nothing in related information, but to the novice-networker, much of this information can be irrelevant.
This book encapsulates only what you need to know, and does not bother you with what you don't. This is also the 'Windows XP Edition' but offers a Win98 walkthrough as well. There are no specific guides for MacOS or Linux.
