I had bought this Fritz box, because I had with my old problems: since the last software update, the equipment could no longer communicate with each other (despite the box is checked in the settings). Unfortunately, that did not just affect my PC (Mac), but also the Airprintdrucker I can operate only with USB cable. I let myself be lulled by the support (no, that's not a bug) and bought this box. The problem is, unfortunately, remained and took me an entire afternoon.
Still, it has some advantages: the with the Dual wireless is just awesome, because you can do the slow devices to another network and not to interfere with the other. The range is not quite as big. like my 3270. But I have a feeling it is faster.
