Hi, has anyone got any ideas what can be done to help.I have just had U.F.B connected through Orcon & have their NF4V router. I have just brought a google Chromecast to play movies off a desktop PC which is connected by an ethernet cable to the router. Every time i play any movie it stutters & buffers every 3 or 4 seconds. I believe the TV & chromecast are fine as i can stream off a tablet using WiFi from the same orcon router.
