How do I secure my home Wi-Fi router?
Short answer
Change the default admin password, use WPA3 or at least WPA2 encryption with a long Wi-Fi password, keep the router’s firmware updated, and turn off remote administration and WPS if you do not use them. Replace routers that no longer receive updates.
The details
Routers sit between every device and the internet, and outdated routers are a common target for botnets. Check the manufacturer’s support page for end-of-life dates.
What to do
- Sign in to the router and change the admin password.
- Choose WPA3 (or WPA2-AES) and a long passphrase.
- Turn on automatic firmware updates where available.
- Disable WPS and remote management.
- Use a guest network for visitors and smart devices.
Terms explained
- Firewall
- A firewall controls network traffic between zones, such as the internet and an internal network, allowing or blocking connections according to rules.
- Encryption
- Encryption transforms readable data into ciphertext that can only be turned back into readable form with the correct key.
