Use this WLAN 500 and the 650s in Devolo Mix: Wireless internet is available in the entire house - almost every corner - often better than the new Apple Airport Xtreme 2013! My first 500 AV Wireless was broken. Exchange about Devolo was unsatisfactory. The products, however, are highly recommended. To this already for 5 years. The 500 WiFi plus is certainly much better than the normal wireless without plug. Here the supplement pays real. The normal 500 Wifi works only since the last firmware release, but still more disorders (data packets lost) than this one.
