Secure Your Router and Home Network in 15 Minutes

Why your router matters

Your router is the front door to every device in your home or small office. If it uses default settings or old firmware, it can be an easy way in. These steps take only a few minutes and make a big difference.

1. Change the admin password

The router's own settings page (or app) has an administrator password, separate from your Wi-Fi password. If it's still the default printed on the label or in the manual, change it to a strong, unique password.

2. Update the firmware

Router manufacturers release firmware updates that fix security holes. Check the router's app or admin page, and turn on automatic updates if available. If your router no longer receives updates, it's time to replace it.

3. Use strong Wi-Fi encryption

• Choose WPA3, or WPA2/WPA3 mixed mode if some older devices need it. Avoid WEP and "open" networks.
• Use a long Wi-Fi password, a passphrase of at least 12–16 characters.
• Rename the network so it doesn't reveal your router model or your family name or address.

4. Turn off features you don't need

• WPS (the "push button" pairing) has had known weaknesses; turn it off if you don't use it.
• Remote management from the internet: turn it off unless you need it.
• UPnP lets devices open ports automatically. Consider disabling it if nothing you use requires it.

5. Create a guest network

Put visitors and smart devices such as TVs, cameras, speakers and plugs on a separate guest network. If one of those devices is compromised, it can't easily reach your computers and files.

6. Review connected devices

Most router apps list every connected device. Remove anything you don't recognise, then change the Wi-Fi password if needed. Keep smart devices updated, and change their default passwords too.
