Fritz!OS 8.20 is now rolling out to AVM’s flagship Fritz!Box 7690 and 5690 routers, delivering a redesigned traffic monitor, upgraded TLS and WPA3‑Enterprise security, dynamic Eco‑Mode power saving, and native Matter smart‑home integration. The firmware arrives automatically for connected devices and can also be installed manually via the router’s web interface, extending performance, security, and IoT compatibility.
Key Features of Fritz!OS 8.20
Advanced Traffic Monitoring
The update introduces a new online monitor that shows real‑time graphs of upstream and downstream bandwidth, latency spikes, and per‑device traffic patterns. Users can pinpoint congestion on DSL or GPON links without third‑party tools.
Enhanced Security Suite
Fritz!OS 8.20 ships with updated TLS libraries, support for the latest WPA3‑Enterprise cipher suites, and an expanded set of intrusion‑prevention signatures, protecting home gateways against emerging threats.
Eco‑Mode Power Management
Eco‑Mode now dynamically scales the router’s CPU frequency based on current traffic load, reducing energy consumption while maintaining peak‑performance throughput.
Built‑in Matter Smart‑Home Support
The firmware adds native Matter compatibility, allowing compatible IoT devices to be discovered and managed directly from the Fritz!Box UI, eliminating the need for external bridges.
Why the Update Matters for Fritz!Box 7690 and 5690 Owners
Both models serve as all‑in‑one gateways for high‑speed broadband, home offices, streaming, and smart‑home ecosystems. The new monitoring tools give administrators clear insight into network health, while the security enhancements align the routers with current industry standards. Integrated Matter support simplifies IoT setup, and Eco‑Mode lowers electricity costs without sacrificing performance.

The update is delivered automatically to devices connected to the internet. For manual installation, follow these steps:
- Open the router’s web interface.
- Navigate to System → Firmware Update.
- Click Check for updates and confirm the download.
