Is the buffering due to routing issues by any chance? I've used similar net supposedly-dedicated to my old IT institute. Downloading was a blaze but streaming... O.M.G. I couldn't even watch twitch because of the constant buffering even at 360p lol.mine is absolutely horse s h i t . downloading speeds are good but video streaming buffers like crazy to the point where i cant even watch a 720p video without buffering every sec. so called 75Mbps i have isp is excitel btw if you havent guessed it already
And is your location Delhi? Excitel was praised in some threads some time ago on this forum itself. Check it out if you haven't.
