2. Power On the Router: Ensure the router is powered on.
3. Press and Hold: Press and hold the reset button for about 10-15 seconds. The lights on the router should flicker or change, indicating the reset process has begun.
4. Release the Button: Release the button and allow the router to reboot. This may take a few minutes.
5. Access Settings: Once the router has fully rebooted, you can access its settings using the default IP address and the default username/password found on the router's sticker. You will then need to reconfigure your WiFi network and set a new password.

Important Note: A factory reset will erase all custom settings, including any port forwarding rules, static IP addresses, or parental controls you may have configured. You will need to set these up again after the reset.

Best Practices for WiFi Security

Changing your WiFi password is a crucial step, but robust network security involves more. Here are essential best practices for 2025:

• Use a Strong, Unique Password: As mentioned, aim for at least 12 characters, combining uppercase and lowercase letters, numbers, and symbols. Avoid easily guessable information like names, birthdays, or common words. Consider using a password manager to generate and store complex passwords.
• Change Default Router Login Credentials: The default username and password for accessing your router's settings are often publicly known. Change these immediately after setting up your router or after a factory reset.
• Enable WPA2 or WPA3 Encryption: Always use WPA2-PSK (AES) or, if your devices support it, WPA3. These are the most secure encryption protocols available for home networks. Avoid WEP and WPA, as they are outdated and easily compromised.
• Update Router Firmware Regularly: Router manufacturers release firmware updates to patch security vulnerabilities and improve performance. Check your router's admin interface periodically for available updates or enable automatic updates if the option exists. In 2025, keeping firmware updated is critical, as new threats emerge constantly.
• Change Your SSID (Network Name): While not a primary security measure, changing your SSID from the default can make your network slightly less of a target for automated scans looking for specific router models. Avoid using personal information in your SSID.
• Disable WPS (Wi-Fi Protected Setup): While convenient, WPS has known vulnerabilities that can be exploited to gain unauthorized access to your network. It's generally recommended to disable WPS if you don't actively use it.
• Consider a Guest Network: If your router supports it, set up a separate guest network for visitors. This allows them to access the internet without giving them access to your main network and devices.
• Secure Smart Home Devices: Ensure all your smart home devices (smart TVs, speakers, cameras, etc.) have strong, unique passwords and are running the latest firmware. These devices can be entry points for attackers if not secured.
• Regularly Review Connected Devices: Periodically log into your router's interface to check the list of connected devices. If you see any unfamiliar devices, investigate immediately and consider changing your password.

The landscape of cyber threats is constantly evolving. Staying informed about security best practices is an ongoing process. For instance, the number of IoT devices is projected to reach over 50 billion by 2025, each representing a potential vulnerability if not properly secured.
