I have a U-M8 quad core android kitkat 4.4 system. The box itself seems fast enough. I have a power line adapter running to the box at average 35Mbits per second and max 50-60 mega bits per second according to the speed test from oopla. Yet when I load something as simple as a South Park episode in 720p it takes a while to load to a point where it doesn't need to stop and buffer. I got my box from droidsticks.co.uk and any help is greatly appreciated !!!!!
