Secure a home Wi-Fi router in 15 minutes

A strong Wi-Fi password is useful, but it is only one part of router security. Before changing settings, locate the router label and the provider's official setup instructions. If the device belongs to your internet provider, some controls may be managed by them.

The short review​

1. Sign in to the router using its local address or official app. Change the administrator password if it is still the default. This is separate from the Wi-Fi password.
2. Choose WPA3 Personal where all devices support it; otherwise use WPA2-AES or a supported mixed mode. Replace a weak Wi-Fi password with a long, unique one.
3. Check for router firmware updates and enable automatic updates if offered. Do not install firmware from an unverified download site.
4. Disable remote administration from the internet unless you truly need it. Review connected devices; a label you do not recognize is a clue to investigate, not proof of an intruder.

Know what you fixed​

Reconnect one trusted device and confirm it reaches the internet. If older devices stop connecting after a security-mode change, check their supported modes before downgrading the whole network. A guest network can separate visitors and less-trusted smart devices. The FTC router checklist covers passwords, encryption and updates. Save a record of your new settings in a password manager, not on a sticker visible to visitors.

Check the new settings​

After saving, reconnect your phone with the new Wi-Fi password and open a known website. Confirm the router still reports the intended encryption mode and current firmware. If you have a guest network, check that a guest device cannot reach the router's admin page or private devices where the router supports isolation.
