Well Ive fixed my Issues with Youtube HTML5 lack of buffering I tried the New browser updates from Non google companies.
Went back to firefox and er it worked.. on the same old 1080p video... as before and boom maxed out the Wifi G..
So swapped to another MP4 browser and the same happened.
The Pause command on the HTML5 Players makes no difference now, the buffering continues on all browsers, Just not Chrome and the other browsers reach near max speed and still buffer even on pause.
This is with no other set up changes here, just changed browser...
No changes to super hub, netgear router, just the browser...
