How to secure your home Wi-Fi network

Most home Wi-Fi security problems come down to two things: a weak password, and outdated encryption left on the factory default. Both are quick to fix once you know where to look in your router's settings, usually accessible by typing your router's IP address (often 192.168.0.1 or 192.168.1.1) into a browser.

For encryption, use WPA3 if your router and devices support it, or WPA2 at a minimum — never WEP or an 'open' unencrypted network, both of which are trivially easy to break into with widely available tools. Older routers sometimes ship with WEP enabled by default for backward compatibility, so it's worth checking even if you've never touched the setting.

For the password itself, treat your Wi-Fi password the same as any other important account: long, random, and unique — not the printed default sticker password most routers ship with, which is often derivable from the router's model and serial number by anyone who can see the box. A long random passphrase is both more secure and, once entered on your devices, no harder to live with day-to-day.

A few other settings worth checking: change the router's own admin password from its default (a separate password from the Wi-Fi password, often overlooked), keep the router's firmware updated, and disable remote administration unless you specifically need to manage the router from outside your home network.
