Smart Tech for Real People: Home Networking: Practical Wi-Fi, Security, and Troubleshooting Without the Guesswork

Your home network carries work, entertainment, smart devices, and everyday communication. When Wi-Fi slows down or one device goes offline, the hardest part is often knowing where to begin.

Smart Tech for Real People: Home Networking explains modems, ONTs, routers, Ethernet, Wi-Fi, mesh systems, guest networks, VPNs, smart devices, internet-provider issues, and troubleshooting in clear language for intelligent non-specialists. Greg Weir shows you how to map the network you already have, identify the part that is actually failing, make small reversible changes, and check whether they solved the real problem.

You will learn how to improve coverage without buying equipment on guesswork; choose practical security and guest-access boundaries; work more effectively with your internet provider; document a network that other people in the household can understand; and troubleshoot problems calmly, one layer at a time.

The book includes diagrams, practical checklists, a troubleshooting quick start, criteria-first equipment guidance, and optional free and open-source companion tools developed by the author. No IT degree is required, and the essential method does not depend on a particular router brand or companion app.
