The most positive first. The connection with the Speedport W921V of Telekom is really easy. Press button on the repeater. Device flashes. WPS Button Press the Speedport ... and the connection is established. I connected the repeater in the living room. The Speedport is in my office. intervene, the hall and the kitchen. So several thick walls. While I was so far only received a very weak WiFi signal with my Galaxy S4 in the living room, this is now but much better. The download rate is 160MB / sec to 220MB / sec, ie increased by around 37% .. However, you must to the smartphone menu change the wireless connection. Under WLAN Settings you will find a new compound which contains the name of your present own wireless connection and the additional _EXT. For this you must again enter the wireless password and has been running it Overall I can say that you have a, if not get here for a relatively low price superior, yet quite satisfactory repeater.
