Updated! Version 2.0 of this book now covers iOS 17, iPadOS 17, macOS 14 Sonoma, and Windows 11.
Perhaps you already have a Wi-Fi network running in your home and office, but you’re dissatisfied with it. Or maybe you’re setting up a new house, apartment, business, or school room with Wi-Fi and need to know the basics about what to get and how to configure it. In either case, this book is for you. After over 18 years of writing regularly about Wi-Fi and answering reader questions, author Glenn Fleishman finds that the same issues still crop up:
- How do I spend the least money to the best effect?
- What’s the best place to put my Wi-Fi gateways?
- Is a mesh network a good idea—and if so, what do I need to know?
- How can I get both high throughput (speed) on my network and solid coverage across everywhere I want to use Wi-Fi?
- What can I do to secure my network against outsiders near my house and elsewhere on the internet?
- How do I add networked hard drives and printers?
- Interference is slowing my network; what can I do to reduce it?
- What’s the best way to extend my network to a garage, yard, or nearby building?
- What’s different about the latest standards—Wi-Fi 6E, Wi-Fi 7, and 802.11be?
This book answers those questions in depth, as well as many others related to Wi-Fi, including how to set up a personal or mobile hotspot with all major operating systems, how to access computers on your network remotely, and why you should use a VPN (virtual private network).

What's New in the Second Edition
The development of Wi-Fi slowed down by the late 2010s after a turbulent first 15 years or so. But no technology stands still, especially as demands increase for higher throughput for video, better coverage and range, and more consistent transmission to keep streaming playback smooth and solid.
Since the first edition of this book, I rolled in changes large and small. This second edition provides a more thorough overview of what’s new and brings the title up to date for 2024. In particular, this book is fully updated for the Wi-Fi 6E, Wi-Fi 7, and 802.11be specifications (see “Wi-Fi Standards”), the expanding availability of the 6 GHz band (see “Pick a Wi-Fi Channel”), and the broad availability of mesh networking gear (see “Build a Mesh Network”). See “The 2020s for Wi-Fi” for an in-depth explanation of major changes.
The update also refreshes the book for the latest operating system releases: Android 14, iOS 17, iPadOS 17, macOS 14 Sonoma, and Windows 11. (For macOS users, I assume you are using Ventura or later, which replaced System Preferences with System Settings; for Windows users, Windows 11.)

Oct. 3, 2018 — The Wi-Fi Alliance announced it’s shifting from labeling certified products with the technical specifications developed at the IEEE engineering group in favor of a simple generational numbering system. Thus, 802.11n becomes Wi-Fi 4, 802.11ac is now Wi-Fi 5, and the slowly emerging 802.11ax will be known as Wi-Fi 6. The changes aren’t fully retroactive: they’re not going back to earlier specifications than 802.11n, as those are no longer widely in use (although they’re supported through backwards compatibility). But it’s a shorter and easier way to market and explain technology, and to see an obvious numeric progression. A future edition of the book will adopt the new numbering scheme, which will take many months to roll out, as packaging and manuals are updated and redesigned. Older products still sold actively may not be updated at all, too.

Excellent book. It covers everything I need to know. I consider myself knowledgeable on routing and security to begin with. My older system needs updating and the info in this book helped me choose. I currently have a DD-WRT based system of a router/repeater. I was hoping to see some reference to that type of router but didn’t. I like this nerdy kind of setup where everything is configurable. Alas…it’s probably a book in itself.
