Take Control of
Wi-Fi Networking and Security

Glenn Fleishman

Setting up and securing a Wi-Fi network can be complicated and confusing. This book helps you over every hurdle involved in picking gateways, setting up a network, adding devices, and securing the network and connected phones, tablets, and computers. It’s useful for those who have set up networks in the past and want to replace them with new gear, as well as people who have never built a Wi-Fi network before.

All Take Control books are delivered in three ebook formats—PDF, EPUB, and Mobipocket (Kindle)—and can be read on nearly any device.

Updated! Version 1.3 of this book now covers iOS 15, iPadOS 15, and macOS 12 Monterey.

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 16 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?
  • 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?

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 Version 1.3

This update includes substantial revisions related to the availability of Wi-Fi in the 6-gigahertz band. In 2021, devices shipped with support for that band alongside the older 2.4 GHz and 5 GHz bands in use for decades. A device that supports the 6 GHz band uses a version of the 802.11ax standard, which the Wi-Fi Alliance has labeled Wi-Fi 6E.

This bandwidth expansion required extension revision throughout the book, notably in the sections “Wi-Fi Spectrum and Wi-Fi Standards” and the chapter “Pick a Wi-Fi Channel.”

This version also includes updates related to the release of iOS 15, iPadOS 15, and macOS 12 Monterey.

Alphabet Soup Replaced with Numbers

Posted by Glenn Fleishman on October 3, 2018

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.
