AVM Fritz! Box 6850 LTE test – a promising but overpriced router

More and more people are choosing a mobilnet subscription for their home, and a professional LTE-capable router is a huge help in this. The 6850 is attractive, but an important ziccert has been missed by the manufacturer.

AVM is very popular in Germany, with a plethora of products, but a router with an LTE modem is a rarity even among them. The 6850 LTE is a mid-range network hub, but even today, user expectations are high at this level, and rightly so.


The white-red 6850 LTE belongs to the group of smaller routers by size. No wonder the hardware specifications, even with the best of intentions, are only moderate. The four-gigabit RJ45 connection and the handling of analog telephone lines and DECT devices are useful, but there is no separate WAN port on the back of the router, and Wi-Fi is not up to the latest standard, only 866 + 400 Mbit / s according to the Wi-Fi 5 standard.

In contrast, the LTE modem is very useful, this is the most important virtue of the router, which is perfectly supported by the well-equipped Fritz! OS system, although the Cat.4 rating with its 150/50 Mbit / s speed is now low. The structure of the interface is significantly different from the solutions of the competitors, so it takes a while to get used to it, but after that it is excellent to use, informative, and even a mobile application has been developed for it.

Extras include not only MU-MIMO, firewall, parental control and priority management, but also special features such as media server, smart home control, printer sharing, power save mode or secure remote access, for example.

Missed ziccer

Although the router’s Dual Band WI-Fi 5 service does not reach the newer standard, it provides excellent coverage and stable data transfer for several devices. Consumption and heating are minimal, and Fritz! Boxes have been performing well for a long time.

The Fritz! Box 6850 LTE works well with several devices, its speed is sufficient for general use, the LTE connection is stable, but on the one hand 150/50 Mb / s is now few and on the other hand one of the most important functions is missing. This is nothing more than a wired WAN connection that, combined with the LTE modem, could bring features like auto-failover and auto-failback.

With these, you can build a seamless network connection, and Fritz! OS is familiar with these features, but the manufacturer has chosen to be the privilege of this larger sibling in the premium category, the 6890 LTE. However, the purchase price of HUF 60,000 is extremely excessive in the absence of a dual WAN connection, faster LTE and Wi-Fi 6.
