The goal was to run through this router the complete data traffic and to use the upstream Fritzbox only as DECT station and the Internet. Unfortunately, it was not possible to configure the router so that the devices connected to the Internet could. The configuration interface is only available in English and makes things for a hobby networkers like myself is not easy. As soon as I connected the router as a switch (cable fritzbox to LAN port on the router), everything worked smoothly. Wired and wireless and network throughput were here on a good to very good level. Since I so however a much needed LAN port lost and could not make use of the required, very comprehensive firewall on the router was such use is no alternative for me. After several attempts, the router on the WAN port on the Fritz box to connect and subsequent failed configuration tests I gave up and returned to the router. Even hours of research on the internet did not work for me. Since the device is still very new and oversized safe on the market and for my needs were opinions (my problem) not to be found almost. Unusable All in all a great piece of hardware with many functions, but for me. Based on my criteria, it is so good three star.
