Hello,
same problem with Firmware 1.60 of Buffalos Europe Website. Using Terratecs Noxon 90elf Internet Radio over W-LAN: Media Server can not be found at first time. Even a restart of LinkStation Duo or Speedport Router doesn't fix that. Using same Device over LAN: Media Server can be found but the mp3-files play just a few moments, then disconnects. LinkStation sometimes appears in the menu on the radio, sometimes it seems the LinkStation is unable to grant access to the Noxon device.
Using the Bluray Player BD-C5500 of Samsung with the newest Firmware (don't know what Version that is): Playback via LAN of .wmv- and avi.-Files also run for a while but then the video stops and an error message from Player appears "No connection to media server". The BD-C5500 is directly connected via Ethernet Switch to the LinkStation.
Now it's my job to fix that and install Version 1.57 for now...
Hope this informations will help you. Excuse my bad english, i tried my best :)
Kind regards from Germany
