Hello! I understand your concern about unauthorized users connecting to your WiFi network even after changing the password due to QR code scanning. Since your Converge router does not have MAC filtering, here are some other methods you can try to secure your WiFi network:
1. Change WiFi Network Name (SSID): Modify your WiFi network name to something unique that doesn't give away your address or personal information. This can make it slightly harder for unauthorized users to identify your network.
2. Enable WPA3 Security: If your router supports it, switch to the latest WPA3 security protocol for stronger encryption. This can help protect your network from unauthorized access.
3. Disable WPS: Disable the WPS (WiFi Protected Setup) feature on your router, as it can be vulnerable to brute-force attacks. This can help prevent unauthorized devices from easily connecting to your network.
4. Use a WiFi Analyzer App: Install a WiFi analyzer app on your phone to detect any unknown devices connected to your network. You can then manually block these devices from your router settings.
5. Set Up Guest Network: If your router supports it, create a separate guest network with a different password. This way, you can provide temporary access to guests without compromising your main network's security.
6. Regularly Monitor Connected Devices: Periodically check the list of connected devices in your router settings to ensure that only authorized devices are connected. Remove any unknown devices immediately.
7. Contact Converge Support: Reach out to Converge customer support to inquire about additional security features or recommendations they might have for securing your network.
Remember to always keep your router's firmware up to date to ρá†ch any security vulnerabilities. I hope these suggestions help improve the security of your WiFi network. Let me know if you have any other questions or need further assistance!
