Verdict

The AVM FRITZ!Box 6591 Cable is a high-performance DOCSIS 3.1 cable router featuring Dual-Band Wi-Fi 5 (802.11ac) with 4x4 MU-MIMO, delivering speeds up to 1,733 Mbps on the 5 GHz band and 800 Mbps on 2.4 GHz. Its extensive connectivity includes four Gigabit LAN ports, two USB 3.0 ports for NAS or printer sharing, and an integrated VoIP telephone system with a DECT base for up to six cordless phones, plus analog and ISDN ports. Key pros include its future-proof cable modem capable of up to 6 Gbit/s downstream and robust FRITZ!OS features like Mesh Wi-Fi and VPN support. Notable cons include its lack of a dedicated WAN port, making it unusable with external modems, and the absence of the newer Wi-Fi 6 standard.
