Unfortunately I barely get above 4Mbps speed in my area, a massive dead zone for internet and mobile (struggle to get 4G and live less than 20min from CBD. Kayo struggles with HD quality for me, but if I Chromecast from my tablet with SD quality it’s fine and doesn’t buffer. Until I get NBN sometime this year I have little alternatives. Anyone know how to use a mobile hotspot with Chromecast?
