When viewing movies from my NAS when passing thru my TP.Link TL SG-3424 the speed will drop to 147kb randomly when I start a movie
if I stop it and restart it it goes back to the normal 78500 kb + (note* when I was using the un-managed TP.Link TL-1024D switch I never had this issue)
is there some setting I need to setup in the TP.Link TL SG-3424

Any Help will be appreciated
