Your Wi-Fi is the front door to everything you do online — email, banking, photos, video calls. Wi-Fi at Home, Wi-Fi Away shows you how to lock it properly in about twenty minutes of one-time setup, then enjoy years of quiet protection.

At home, you'll change the router password most people never touch, replace the forgettable sticker password with a passphrase you'll actually remember, set up a guest network for visitors and smart gadgets, and make sure your security type is WPA2 or WPA3. Away from home, you'll learn the coffee-shop rules: when to use your phone's hotspot instead, what to avoid on public Wi-Fi, and how to "forget" networks when you leave.

The final chapter covers the plain signs something's wrong and exactly what to do about it — plus a "Do this today" box with three fifteen-minute wins.
