The Wifi Networking Book

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.

'The WiFi Networking Book: WLAN Standards: IEEE 802.11 bgn, 802.11n, 802.11ac and 802.11ax' starts from the ground up for a new user and does a gradual progression into the technical details around IEEE 802.11 Wireless Lan communications standard. The book details the 'legacy' 802.11 stack (a/b/g) and also goes into the latest wave of 802.11 standards - 802.11n, ac and ax. Introduction A wireless LAN (WLAN) is a data transmission system designed to provide location-independent network access between computing devices by using radio waves rather than a cable infrastructure . In the corporate enterprise, wireless LANs are usually implemented as the final link between the existing wired network and a group of client computers, giving these users wireless access to the full resources and services of the corporate network across a building or campus setting. The widespread acceptance of WLANs depends on industry standardization to ensure product compatibility and reliability among the various manufacturers. The 802.11 specification as a standard for wireless LANS was ratified by the Institute of Electrical and Electronics Engineers (IEEE) in the year 1997. This version of 802.11 provides for 1 Mbps and 2 Mbps data rates and a set of fundamental signaling methods and other services. Like all IEEE 802 standards, the 802.11 standards focus on the bottom two levels the ISO model, the physical layer and link layer. Any LAN application, network operating system, protocol, including TCP/IP and Novell NetWare, will run on an 802.11-compliant WLAN as easily as they run over Ethernet.

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.

With more than 15 billion Wi-Fi enabled devices, Wi-Fi has proven itself as a technology that has successfully evolved over the past 25 years. The need for high-speed connectivity is growing, as Wi-Fi has evolved into a fundamental utility that is expected to be available everywhere. This comprehensive resource covers six generations of Wi-Fi standards including protocol, implementation, and network deployment for both residential and enterprise environments. It will provide readers with a new understanding of how to approach and debug basic Wi-Fi problems, and will grant those wondering whether to pick 5G or Wi-Fi 6 for their product the clarity needed to make an informed decision. Readers will find in-depth coverage of Wi-Fi encryption and authentication methods, including explorations of recently uncovered security vulnerabilities and how to fix them. This book also provides detailed information on the implementation of Wi-Fi, including common regulatory and certification requirements, as well its associated challenges. This book also provides direction on the placement of Wi-Fi access points in indoor locations. It introduces the most recent Wi-Fi 6E certification, which defines requirements for devices operating on the newly opened 6 GHz band. Wi-Fi 6 is then compared with 5G technology, and this resource provides insight into the benefits of each as well as how these two technologies can be used to complement each other.
