Book Description
Get more from your Wi-Fi network Version 1.4, updated November 21, 2022 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.n 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). 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. Covers macOS, Windows, iOS, Android, and Chrome OS.

Book Description
At 36,000 feet, Wi-Fi converts our airline seats to remote offices. It lets us read email in airports, watch video in coffee shops, and listen to music at home. Wi-Fi is everywhere. But where did it come from? Wi-Fi and the Bad Boys of Radio takes us back to when the Internet was first gaining popularity, email took ten minutes to load up, and cell phones were big and unwieldy. But Alex Hills had a vision: people carrying small handheld devices that were always connected. His unwavering purpose was to change the way we use the Internet. After being a teenage "ham operator" and bringing radio, TV and telephone service to the Eskimos of northern Alaska, Dr. Hills led a small band of innovators to overcome "the bad boys of radio" - the devilishly unpredictable behavior of radio waves - and build the network that would become the forerunner to today's Wi-Fi. "I know of no one so capable of telling the Wi-Fi story and explaining so clearly how the technology works. Alex Hills is certain to capture the public imagination with this new book." Jim Geier, Principal Consultant, Wireless-Nets, Ltd. and Wi-Fi author "Alex Hills has contributed to the developing world and to developing advanced wireless technology at one of the world's most tech-savvy universities. Working on both frontiers, Dr. Hills pioneered wireless Internet and launched a revolution in the way the world communicates. His story of how we "cut the cord" begins in a place where there were no cords to begin with -- remote Alaska." Mead Treadwell, Lieutenant Governor of Alaska and former Chair, United States Arctic Research Commission Alex Hills is Distinguished Service Professor of Engineering & Public Policy and Electrical & Computer Engineering at Carnegie Mellon University. Dr. Hills is frequently invited to speak at conventions, conferences, university seminars, corporate training sessions, and community events. His talks, with their vivid stories and clear explanations of technology, have been well-received by audiences throughout the United States and in more than twenty foreign countries. An inventor with eleven patents, Dr. Hills can write and speak in technical jargon. But in his writing, as in his talks, he speaks to everyone -- technical specialists and the public alike. People of all backgrounds have been fascinated by his contributions to Scientific American and IEEE Spectrum magazines -- articles that explain technology in a style that is clear to any reader.

Book Description
As we all know by now, wireless networks offer many advantages over fixed (or wired) networks. Foremost on that list is mobility, since going wireless frees you from the tether of an Ethernet cable at a desk. But that's just the tip of the cable-free iceberg. Wireless networks are also more flexible, faster and easier for you to use, and more affordable to deploy and maintain.The de facto standard for wireless networking is the 802.11 protocol, which includes Wi-Fi (the wireless standard known as 802.11b) and its faster cousin, 802.11g. With easy-to-install 802.11 network hardware available everywhere you turn, the choice seems simple, and many people dive into wireless computing with less thought and planning than they'd give to a wired network. But it's wise to be familiar with both the capabilities and risks associated with the 802.11 protocols. And 802.11 Wireless Networks: The Definitive Guide, 2nd Edition is the perfect place to start.This updated edition covers everything you'll ever need to know about wireless technology. Designed with the system administrator or serious home user in mind, it's a no-nonsense guide for setting up 802.11 on Windows and Linux. Among the wide range of topics covered are discussions on: deployment considerations network monitoring and performance tuning wireless security issues how to use and select access points network monitoring essentials wireless card configuration security issues unique to wireless networks With wireless technology, the advantages to its users are indeed plentiful. Companies no longer have to deal with the hassle and expense of wiring buildings, and households with several computers can avoid fights over who's online. And now, with 802.11 Wireless Networks: The Definitive Guide, 2nd Edition, you can integrate wireless technology into your current infrastructure with the utmost confidence.

Book Description
Even though computer wireless networks haven’t been around for very long, the basic technology used to create them is more than 100 years old. WiFi uses radio waves to send and receive data and connect smartphones, tablets, and computers to the Internet. Today, almost everywhere you go has WiFi, including schools, coffee shops, and the library. The inner workings of this ubiquitous technology will fascinate readers, who probably use it every day. Accompanied by full-color photos, the main content will introduce innovators like Nikola Tesla and other electronics history, as well as the future possibilities of wireless connection.
