Technique is good if it works and can take it easy in operation. This is the case for this device. Unpacking plug, start WPS on the router (Speedport 724v) and WPS start at Netgear. Finished! The WLAN will be extended with sample "Mein_WLAN_EXT" the WPA key is passed from the base / router for Netgear. LAN cable from Netgear for Media Receiver T-COM, connection errors. No crashes, no other errors. You can still register at the Netgear and see the configuration parameters via a browser Login or change it if necessary. Wi-Fi can be deactivated via a switch on the Netgear. So far I could not find any errors in the set up and use and thus give an unqualified recommendation to buy.
