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.

i think you didn't do anithing wrong this sounds more like a network problem,
(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.
