I'm with cable Germany and had previously a Dlink 615 of you gave up the ghost.
With the Asus router I'm super happy. It is more stable than the 615 you and the WLAN to get to 10 Mbyte / s (with the Dlink were previously only 1-2 MB / s).
It is easy to configure and connect, for the price, there is nothing to complain about.
