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 1.2 of this book now covers iOS 14, iPadOS 14, macOS 11 Big Sur, WPA3, and the 6 GHz Wi-Fi band.

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).

Also available: You can save money by buying this book as part of a three-book bundle, which also includes Take Control of Securing Your Mac and Take Control of iOS & iPadOS Privacy and Security. Buy all three books for $25.78, which is 40% off the combined cover prices of $42.97. Add 3-Book Bundle to Cart

If you have any question about overhauling your network, setting up a new one, or just finally figuring out something that’s never worked, this book has the answer.

He has also written dozens of editions of books in the Take Control series. He spent 2019 and 2020 building 100 tiny type museums full of real printing artifacts—a few remain available for purchase. Glenn lives in Seattle with his wife and two children.

This version of the book mostly addresses minor changes, such as the release of iOS 14 and iPadOS 14 for Apple mobile devices, and macOS 11 Big Sur for Mac computers. It also covers:

  • The rise of WPA3, the replacement for WPA2 that adds better protections against network sniffing. While WPA3 was in some devices in 2019, it’s now more broadly available. The previous version of the book mentioned WPA3; this version makes it clearer that you can now use it. For more on WPA3, read “WPA, WPA2, and WPA3 Background.”
  • The addition to iOS 14/iPadOS 14 of Private Address, a feature that resists tracking users by the unique address on the Wi-Fi adapter sent when they connect to a network. See “Private Addresses in iOS or iPadOS.”
  • The upcoming availability of a whopping 1.2 GHz of new spectrum in the United States for Wi-Fi use in the 6 GHz band. This new flavor of 802.11ax will be called Wi-Fi 6E and will appear in routers starting in early 2021. I address this throughout the book, and read more specifically in “More Bandwidth Coming: 6 GHz, Wi-Fi Standards, and Spectrum Trade-Offs.”

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.
