1. Choose a Strong Router

• Purchase a Reliable Router: Invest in a high-quality router from a reputable brand.
• Update Router Firmware: Ensure the router firmware is up to date to protect against vulnerabilities.

2. Change Default Settings

• Change Default SSID: Rename your Wi-Fi network (SSID) to something unique and not easily identifiable.
• Change Default Passwords: Change the default administrative password for your router to a strong, unique password.

3. Enable Network Encryption

• Use WPA3: If available, enable WPA3 encryption for the highest level of security. If WPA3 is not available, use WPA2.
• Avoid WEP: Never use WEP encryption as it is outdated and insecure.

4. Create a Strong Wi-Fi Password

• Strong Password: Use a strong, complex password for your Wi-Fi network.
• Passphrase: Combine letters (uppercase and lowercase), numbers, and special characters.

5. Disable Remote Management

• Disable Remote Access: Turn off remote management features to prevent unauthorized access to your router.

6. Enable Firewall

• Router Firewall: Ensure your router’s built-in firewall is enabled.
• Device Firewalls: Enable firewalls on individual devices connected to your network.

7. Segment Your Network

• Guest Network: Set up a separate guest network for visitors to keep your main network more secure.
• IoT Devices: Consider placing IoT devices on a separate network to minimize risk.

8. Update Devices Regularly

• Firmware Updates: Regularly update the firmware of your router and other network devices.
• Software Updates: Keep all connected devices, including computers, smartphones, and smart devices, updated with the latest security patches.

9. Disable Unnecessary Features

• WPS (Wi-Fi Protected Setup): Disable WPS to prevent easy unauthorized access.
• UPnP (Universal Plug and Play): Disable UPnP if not needed, as it can expose your network to vulnerabilities.

10. Monitor Network Activity

• Network Monitoring Tools: Use network monitoring tools to keep an eye on connected devices and unusual activity.
• Regular Checks: Periodically review your network’s device list for unknown or suspicious devices.

11. Secure Physical Access

• Router Location: Place your router in a central, secure location within your home to reduce the risk of physical tampering.
• Lock Router: If possible, lock your router in a cabinet or secure area.

12. Educate Household Members

• Awareness: Educate everyone in your household about the importance of network security.
• Best Practices: Teach them best practices for using and connecting to the network securely.

Additional Tips

• Use a VPN: Consider using a VPN to encrypt your internet traffic, especially when using public Wi-Fi networks.
• Disable SSID Broadcasting: For added security, you can disable SSID broadcasting, but this may make connecting new devices more cumbersome.
• Regularly Review Security Settings: Periodically review and update your router’s security settings to ensure ongoing protection.
