I hope, I can explain my problem good enough to get some help here :
I have connected a Soundbridge Home Music device to my Fritzbox via WLAN.
DHCP Server is off, so I had to configure the Soundbridge-IP manually. That is not the problem, that really works fine.
I can hear Internet-radio, but I am not able to get access to the Fritzbox UPNP Musicserver.
Any ideas, what to do ?
DO you need more information ?
