Hello. I've setup a low-end desktop machine to only have the job of being the media server to my DSM-520. It has 2 USB external drives connected to it with all of the files I want to share. I'm using the latest Dlink Media Server software and have added the proper folders just fine. This desktop connects (wired) to my wireless router and my DSM-520 connects to the same router wirelessly. I've setup the DSM-520 properly and once it was setup, all worked fine. I could even stream my DVD movies just fine. This was two nights ago. Yesterday morning, I decided to turn on my DSM-520 again and play another movie and suddenly I got the "Server Not Found" message, meaning it couldn't find my media server. Obviously the desktop was still on and the software still running, so why did it do this? Just by chance, I went into the DSM-520 options and just had it redo the wireless settings so that it would fetch its IP via DHCP again. After I did this, suddenly the server WAS found and all worked fine again. It worked fine last night too. This morning, same issue as before, server not found. Redoing the IP via DHCP DIDN'T work this time, so now I'm at a loss. Do I need to setup a static IP or something or is this device known to spontaneously not work like this? Thanks for your time.
