After a bit of foraging I then met with the R7000, who has promised me right away when it comes to the technical data on the paper and the look ...
I have the R7000 via a Gigabit LAN port of the Fritz box connected to this, the other end of the cable plugged in WAN port on the R7000. I also turned off the WLAN of the Fritz box and the R7000 as an access point (AP) to be found in the advanced settings after the initial setup, set. As AP therefore, to see the WiFi or home network all connected devices (WLAN printer for example), since these are now in the same network group.
Establishment ran by itself, just by clicking only the web-based setup and configure the router ready. After that I had in the advanced settings only once halt the router as a AP Setup (1 clicking on the box), start router and you're done.
Now I have throughout the house and in the garden 4-5 of 5 bar WLan reception to 2,4G network and 3-5 bar in the 5G network.
The speed is amazing! Streaming movies via Amazon or Watch Ever matter on which device in the WLAN goes without dropouts.
For me it was worth it to grab something deeper into their pockets. I am completely satisfied with the router!
