Why securing your home Wi-Fi matters

An unsecured Wi-Fi network can allow attackers to:

  • Access your network without permission.
  • Intercept unencrypted data.
  • Compromise devices connected to your network.
  • Spread malware across your home network.

Essential steps to secure your Wi-Fi router

  1. Change the router’s default username and password.
    • Default credentials are often publicly available.
    • Use a long, unique, and random password.
  2. Keep your router firmware up to date.
    • Install updates regularly.
    • Enable automatic updates if supported.
  3. Change the default Wi-Fi name (SSID).
    • Avoid using the manufacturer’s default name.
    • Don’t include personal information such as your name or address.
  4. Set a strong Wi-Fi password.
    • Use a memorable passphrase of 5 to 7 unrelated words.
    • Make it at least 16 characters long.
    • Don’t reuse passwords from other accounts.
  5. Use strong Wi-Fi encryption.
    • Prefer WPA3 Personal.
    • If WPA3 isn’t available, use WPA2 AES (also called WPA2-PSK).
    • Avoid WEP, WPA, or WPA2-TKIP, as they are outdated and insecure.
  6. Disable remote management.
    • Prevents people from managing your router over the internet.
  7. Disable WPS (Wi-Fi Protected Setup).
    • WPS can be exploited to gain unauthorised access.
  8. Disable UPnP (Universal Plug and Play).
    • While convenient for smart devices, it can expose your network to attacks.
    • Enable it only temporarily if absolutely necessary.
  9. Secure the router physically.
    • Keep it in a location where others cannot easily access or reset it.
  10. Enable a Guest Wi-Fi network.
    • Give guests a separate password.
    • Connect smart home and IoT devices to the guest network whenever possible to isolate them from your main devices.
