I now have my Media Receiver 303 with this adapter via WLAN to a Speedport W721V. It works without problems, the TV / video stream is displayed as it should be. Thus this adapter is an affordable alternative to WLAN Bridge Telekom for the Entertain offer! Until now, at many (again) the question of whether the thing forwards the multicast signals which are necessary for Entertain. Yes, it comes with it !! :-)
