Securing Your Home Network
Your router is the front door to every device in your home. A few settings make it far harder to misuse.
Every device in your home connects through your router, which makes it a single point worth securing. The good news is that a handful of one-time settings dramatically raise the bar, and none of them require technical expertise.
Start by changing the router administrator password. Many routers ship with a default admin login that is public knowledge, and leaving it unchanged lets anyone who reaches the router take control. Set a strong, unique password for the admin interface, separate from your wifi password.
Make sure your wifi uses modern encryption, the latest WPA standard your router supports, and protect it with a strong passphrase. This stops neighbors and passers-by from joining your network and reaching your devices.
Keep the router firmware updated, since routers have security flaws like any other software and updates fix them. Many modern routers update themselves; confirm that yours does or check occasionally.
If your router offers a guest network, use it for visitors and for smart-home gadgets. Cheap internet-connected devices are often poorly secured, and isolating them on a guest network means a compromise of a smart bulb or camera cannot reach your computer or phone. These steps take perhaps twenty minutes once, and they protect every device in the household from then on.
