I use the Fritzbox in a 130sqm apartment without many walls and quite large spaces without many items. The distance between Fritzbox and coffee is about 8 meters, between them there is a wall with an open passage in direct line of sight. Result: I can stream to the iPhone no audio stream liquid to AppleTV. When backing up (laptop WLAN -> Server Wired) the transmission power reaches only 8 MB / s (rounded up) at a distance of 50cm. This is frustrating and a high-priced solution is not appropriate. A Loaned installed 7490 did not improve, and support the equipment used no AC-Fi. The advertised speeds and improvements in my experience, illusory, deceptive marketing terms that are based on laboratory tests and wild reality can not withstand. AVM is here in the good company of all the other suppliers.
Four stars I forgive because I best find functional and interface among previously the received to face routers with distance (5 Stars), the transmission power but is so bad that I would for this call at best 2 star and it is this now times is for me in the foreground , How about again with external antennas? ;)
