Hi there, I have a similar problem with my LS/QVL1C2. I updated the firmware last night and as usual, it didn't reboot the
NAS properly so, I RESTARTED the NAS today, even though it was running and still could not access the folder I have called
entertainment with all my video and music files through my Samsung BD 8500A DVD recorder (which was NOT a problem until the upgrade)
I have checked the settings for the DLNA server on the NAS and the IP address of the DVD unit it listed but, it now only works SOMETIMES.
I did also check my router to make sure that it was not denying service and I checked the DVD recorder to make sure there were no issues
with it but, I still get the NAS go missing when I try to access to watch my Media Files.
BTW, have had NO issue with accessing the NAS through a computer.
