I'm using an AMP2 & DAC2HD in a WiFi environment. Ethernet is not available. The problem arises, because of the metalcase and some problems in the building. I have found support by a German company who put the WiFi & BT signal on a cable (geeks-r-us). This is working fine for me.
Now everything is running the way i want. ThanX to all helped me, especially Daniel and Steve. Best regards Winnie.
