After connection to the Topfield receivers the Netgear now accesses WNCE2001 the wireless signal and outputs it via LAN cable to the receiver on.
The power supply can be made with the power supply unit contained in the package or with the also included USB cable. The latter makes me that even the Netgear is only when the receiver is in power.
So one can say that exactly what I wanted to achieve, works beautifully. After my previous experience is particularly noteworthy that it took only one attempt until everything worked perfectly !!!
And the device is so small and handy that it can not be seen behind the receiver.
Here is the device to find: Netgear Universal WiFi Internet Adapter WNCE2001-100PES (Ethernet to WLAN)
