i think you didn't do anithing wrong this sounds more like a network problem,vprasinos wrote:...
When I was using Samsung's Media Manager, playback would stop and sometimes the TV would hang and shut itself off, other times it would loose the network connection and I would have to go in the Settings to switch from "Auto" to "Manual" IP addressing and then the connection would test ok.
...
(bad cable, low quality antenna on WiFi, switch, defect nw-card....)
it also can be a problem with windows network settings, very hard to make a remote diagnosis.
you also can try to search in google for "windows disable qos"
may it helps too.
