That’s the fastest FritzBox in the world

If you look at the technical specifications of the FritzBox 6660 Cable, you will find one thing above all. The latest AVM internet router is fast. The router promises a lot on the side of the Internet cable connection as well as on the home network side. It starts with DOCSIS 3.1 and Gigabit Internet and ends with WLAN 6 with 3 Gbit / s and a network connection with 2.5 Gbit / s data rate.

The home network connections: 2.5 GBit / s LAN and WIFi 6

At first glance, the router is indistinguishable from its VDSL competitors such as the FritzBox 7590. The form factor is the classic flat design with the shark fins, the exterior is completely white.

The box does not show the high speed either – almost not. Because on the back of the Fritzbox 6660 Cable you will find a remote LAN socket labeled “2.5G”. This does not describe a mobile radio standard, but the built-in speed class of the Ethernet adapter. Four additional sockets allow gigabit data rates. Few users will need the 2.5 Gbit / s connection at the moment, most end devices and switches for home use are now equipped with gigabit ports. Due to the lack of a corresponding device, we could not test the performance.

The connections of the Fritzbox 6660 Cable

On the radio side, the Fritzbox 6660 Cable is equipped with WLAN 6 AX. This router is the first Fritzbox in the large Berlin range that comes with WiFi 6. But what does this bring in practice? The data sheet promises 2,400 plus 600 Mbit / s. That’s a whopping 3 Gbps. When operating on a Gigabit connection from Vodafone, it should not be a problem to get a Gigabit on a Samsung Galaxy S20 Ultra that also supports Wifi 6. At least that’s what the normal user thinks.

WLAN 6 in practice

In fact, the WLAN 6 practice looks different. First of all, the total of 3 Gbit / s is once again a gross data rate. All router manufacturers use these to advertise across the board, although users can never get these data rates in practice. You also need a device that already supports Wifi 6. And to get the gigabit data rates, the end device must also support a 160 megahertz spectrum in the 5 GHz range (HE160).

This is not the case with the Galaxy S20 Ultra, it can only do half with the HE80. The result: the practical data rate does not exceed 700 Mbit / s – and that only in the immediate vicinity of the FritzBox. This is certainly not the FritzBox, but the cell phone – but it shows how far the AVM router is ahead of its time.

Testing the software of the FritzBox 6660 Cable: a feature is missing

There is little to say about the software of the FritzBox 6660 Cable: it comes with almost all the known features of the FritzOS. It starts with the WiFi mesh and parental controls, goes through telephony and fax functions to the first smart home approaches. The router has recently been updated to version 7.15 of FritzOS. We could not find any gross errors in daily use, only the data consumption count does not work. But since this counts as a freestyle in times of flat rates, it cannot be called a real flaw.

However, it is disappointing that the FritzBox 6660 Cable does not offer the DVB-C streaming function known from other cable Fritz boxes. It is not advertised, but can be expected for Fritzbox users. With this function, the Fritzbox converts the TV cable signal into a streaming signal that you can then see in your entire apartment via smartphone, tablet or web browser. Weak too: The USB interface only supports USB 2.0. Annoying for anyone who wants to use this interface to integrate their NAS into the home network.

Conclusion: high-end box with future visions

The bottom line when testing the AVM FritzBox 6660 Cable is a solid high-speed cable Fritzbox as a result. Anyone who reworks their home network in combination with a fast cable connection should at least consider this box. In the long-term test, the box convinced in the typical AVM manner: It is a workhorse and easily manages to distribute the gigabit from the Internet even in the home network – if the end devices fit.

It is doubtful whether changing the Fritzbox is only worthwhile for WLAN 6 or the 2.5 gigabit LAN socket, for example. It would only be worthwhile if you are sure that your end devices can process the corresponding data rates. If you want to invest in a new home network anyway and connect to the Internet via a cable connection, you won’t go wrong with the FritzBox 6660 Cable. With the FritzBox, your networking needs for the coming years should be covered. The currently just under 230 euros for the router are well spent.
