Setting Up a Secure Home Network
A beginner-friendly guide to improving your Wi-Fi security.
1. Change Your Router’s Default Credentials
Most routers use generic login details like admin/admin. These are widely known and easy for attackers to guess.
- Log into your router’s IP (usually
192.168.0.1 or 192.168.1.1).
- Change both the router login username and password.
Pro Tip: Store your password in a secure place or password manager.
2. Use WPA2 or WPA3 Encryption
Encryption secures the data sent between your devices and router. WPA3 is the latest standard, but WPA2 is still secure for most homes.
- Go to your router's Wireless or Security settings.
- Select WPA2 (or WPA3 if available) and set a strong passphrase.
3. Rename Your Network (SSID)
Don't advertise your router’s brand in your Wi-Fi name (e.g., “Linksys123”). A custom name avoids revealing potential vulnerabilities.
Tip: Avoid using personal info like your full name or address in your SSID.
4. Disable WPS
WPS (Wi-Fi Protected Setup) allows easy device connection, but it's insecure and often targeted in brute-force attacks.
- Turn off WPS in your router settings under “Wi-Fi” or “Advanced.”
5. Enable Guest Network (Optional)
If you have frequent guests, enable a separate network just for them. This keeps your personal devices isolated.
- Limit guest network access — no admin or file sharing permissions.
- Give it a different name and password.
6. Update Firmware Regularly
Manufacturers release updates to fix security flaws. Set a calendar reminder to check once a month.
- Look for a “Firmware Update” section in your router settings.
- Enable auto-updates if available.
