Is my Synology router infected? - Tech Support

If you own a Synology router and suspect that it might be infected, it's essential to take immediate action to protect your network and devices. In this article, we will guide you through some common signs of a compromised router and provide steps to help you identify and resolve any potential infections.

Signs of an infected Synology router

1. Slow network performance: If you notice a significant decrease in your internet speed or experience frequent buffering while streaming, it could be a sign of a compromised router. Malware or unauthorized processes running on your router can consume network resources and impact performance.

2. Unexpected network activity: Keep an eye on your router's activity lights. If you notice excessive blinking or continuous network activity, it could indicate unauthorized access or malware transmitting data without your knowledge.

3. Unusual behavior: If your router starts acting strangely, such as rebooting on its own, disconnecting devices randomly, or displaying unfamiliar error messages, it's worth investigating for possible infections.

4. Blocked websites or redirected traffic: If you find that certain websites are inaccessible or if your browser redirects you to unfamiliar or suspicious sites, your router might be compromised. Malware can manipulate DNS settings to control your internet traffic.

5. Unauthorized access to your router settings: If you notice changes in your router's configuration without your knowledge, such as modified Wi-Fi passwords or new port forwarding rules, it's a strong indication that your router has been compromised.

Steps to identify and resolve router infections

1. Update your router's firmware: Keeping your router's firmware up to date is crucial for security. Visit Synology's support website and download the latest firmware for your specific router model. Follow the instructions provided to install the update, which often involves accessing the router's web interface.

2. Change default login credentials: Many routers come with default usernames and passwords, making them vulnerable to attacks. Change the default login credentials to unique, strong passwords that are difficult to guess. This step ensures that unauthorized users cannot access your router's settings.

3. Enable firewall and security features: Synology routers offer built-in firewall and security features to protect your network. Access your router's web interface and enable these features, such as Intrusion Prevention, DoS protection, and DNS over HTTPS (DoH).

4. Scan your network for malware: Use a reliable antivirus or antimalware software to scan your network devices, including your router. Many antivirus programs offer network scanning options that can detect and remove any malicious software present on your router.

5. Reset your router to factory settings: If you suspect severe infection or are unable to remove malware, it may be necessary to reset your router to its factory settings. This step erases all custom configurations, so make sure to back up any important settings beforehand.

6. Change Wi-Fi passwords: After resetting your router, change your Wi-Fi passwords to prevent unauthorized access. Choose strong, unique passwords and consider enabling WPA2-PSK or WPA3 encryption for enhanced security.

Conclusion

Protecting your Synology router from infections is essential to maintain a secure network environment. By staying vigilant and following the steps mentioned above, you can identify and resolve any potential infections, ensuring the safety of your data and devices.
