Security Best Practices for AVM FRITZ!Box 6660 Cable

Protect your network by following these essential security recommendations:

Change Default Password Immediately

CRITICAL

The first thing you should do after logging into your AVM FRITZ!Box 6660 Cable is change the default password. Use a strong password with at least 12 characters, mixing uppercase, lowercase, numbers, and symbols.

Update WiFi Encryption

HIGH

Ensure your WiFi is using WPA3 or at least WPA2 encryption. Avoid WEP and WPA as they are easily cracked. Change the default WiFi name (SSID) to something that doesn't reveal your router model.

Keep Firmware Updated

HIGH

Regularly check for firmware updates for your AVM FRITZ!Box 6660 Cable. Manufacturers release updates to patch security vulnerabilities. Enable automatic updates if available.

Disable Remote Management

MEDIUM

Unless absolutely necessary, disable remote management features. This prevents attackers from accessing your router from the internet.

Enable Firewall

MEDIUM

Make sure the built-in firewall on your AVM FRITZ!Box 6660 Cable is enabled. Consider enabling additional security features like DoS protection and port filtering.

Disable WPS

MEDIUM

WiFi Protected Setup (WPS) has known security vulnerabilities. Disable it unless you absolutely need the convenience.

💡 Pro Tip: Create a guest network for visitors to keep your main network more secure. Most modern routers including AVM FRITZ!Box 6660 Cable support this feature.
