Since the Fritzbox update 7.20, an additional Fritzbox function that enabled the integration of a Fritzbox as a network drive (smb) in the Teufel Streaming App can no longer be used for Teufel Streaming.
The reason is probably a change within the Fritzbox firmware, which makes this function no longer usable. We ask for your understanding of this.
Alternatives
A) Remove the USB stick from the Fritzbox and plug it into the USB port of your Teufel Streaming device instead (in case of multiple devices, plug it into the host device).
B) Use the Fritzbox media server instead of integrating the Fritzbox as a drive (NAS).
