Verdict

The AVM FRITZ!Box 6890 LTE is a high-performance hybrid router designed to handle both VDSL/DSL (up to 300 Mbps with Supervectoring 35b) and LTE Cat 6 (up to 300 Mbps download/50 Mbps upload) connections, offering an intelligent fallback feature that switches to mobile data if landline internet fails. Key characteristics include high-end dual-band Wi-Fi 5 (802.11ac + n) with 4x4 MU-MIMO reaching up to 2,533 Mbps, an integrated DECT base station for up to six cordless phones, and a versatile array of ports: four Gigabit LAN, one dedicated Gigabit WAN, a USB 3.0 port, and a mini-SIM slot. Its main pros are exceptional connection reliability due to the redundant hybrid system, comprehensive telephony and smart home hub integration via FRITZ!OS, and Mesh Wi-Fi support for expanded coverage. Major cons include a relatively high retail price compared to standard routers and its lack of support for newer 5G or Wi-Fi 6 standards, as it is an older model in AVM's lineup.
