AVM FRITZ!Box 6670 Cable - Cable Router

The AVM FRITZ!Box 6670 Cable is a cable modem and Wi-Fi 7 router designed for cable internet providers. It uses EuroDOCSIS 3.1 and 3.0 standards, supporting download speeds of up to 6000 Mbit/s. The device features Wi-Fi 7 (802.11be) technology, offering a combined wireless data rate of up to 3500 Mbit/s. Dual-band operation across the 2.4 GHz and 5 GHz frequencies manages bandwidth distribution for multiple connected devices. These wireless protocols are designed to increase throughput and reduce latency for data-intensive applications. By combining a modem and router in one unit, the product simplifies network setup for cable households. Users requiring high-speed access for 4K streaming or large file transfers can take advantage of the full capacity of the DOCSIS 3.1 interface.

The hardware includes five Ethernet LAN ports: one 2.5 Gigabit port and four 1000 Mbit/s ports for high-speed wired connections. Connectivity is further supported by an RJ11 port for analogue telephones and a USB 2.0 port for local network storage. Integrated Zigbee and DECT support allow the unit to act as a hub for smart home devices and cordless handsets. Security features include a built-in firewall and VPN support for both WireGuard and IPSec protocols. The local network is managed via a web-based interface, which provides tools for dynamic DNS and guest access. Wireless permissions can be configured to isolate visitor traffic from the primary home network. The device has a typical power consumption of 13 W and weighs 1120 g.
