In my office I have a Denon RCD-N7 mini stereo, lately it has decided not to connect to my network be it via Ethernet or Wifi. I have tied a selection of Cat5 and Cat6 leads. I have also tried Wifi and neither will connect.  The unit will not play music via USB returning a "file is empty" message, it previously had no issues playing MP3s.


The unit plays FM fine. I haven't tried a CD as I have them stored and its not possible for me to get to the safe right now, stupid mobility problems.


Anyone got any ideas? I have not tried the three finger reset on the unit yet.
