I have an Actiontec all in one (DSL modem-router) which is supplied by phone company there are 4 ports of which one must go to the cis430 HD PVR (for IP tv) so that leaves me 3 ports. i have 2 computers connected so that leaves me one Currently have that last port connected to a WD Live hub. (all connections using cat5e) i stream some movies to the wd live from one of the computers. I also have a sony blueray player and sony LCD tv what i wanted to do is connect the tv/blueray player and wdlive to the network. so i got a cisco SD2005 switch. I plug the cat5e from the wdlive into the switch then connect all 3 devices to the switch. It works fine for a bit but i then run into problems. When streaming to the wdlive from computer i get stuttering (video pauses). The wd/computer streaming work fine when direct connected. anything special i should be doing? i tried searching for solutions and from what i can see i have it connected the right way.
