I have had Media Server called "Asus" (= Media Server Name) configured all the time, and two usb thumb drives (containing mp4-files) attached to the router. When I open my television, select the Media Player and choose Video, I can see the Asus Server OK and it is "Connected". And I can play the video files. No problem.
But when I reboot or shut down the router (I use to turn off my router quite often, when I am not home etc.) and open the television later, the Media Player of my Sony televison shows two or maybe several Asus Servers listed. The status of one of these is "Connected" and the other(s) are "Disconnected". When I look at the info of these Asus Servers, the "Connected" one has IP 192.168.1.1, and those marked "Disconnected" have no IP address (= IP: -)
The "Connected" Asus Server works OK, no problem. And I can manually delete these "extra" non-working Asus Servers from my TV menu as they appear. And re-scan the available Servers. But they keep coming back all the time, seemingly after turning off the router and turning it on again. Seems like my Asus Server of the router changes a bit after every reboot and television will see and list it as a new Server available?
With earlier firmware versions (mainly non-Merlin ones) I haven't never seen this problem.
edit: Noticed that when I run the Server Diagnostics from menu of my Sony television, the uuid key (UDN) of that "Connected" Asus Media Server gets changed after every reboot of the router. Is this normal? IP address and MAC (of the router) and TCP port (8200) won't change.
edit2: Installed 380.65_beta2. It didn't fix the problem.
