I am using 12.04, FF 16.0.2, Flash 11.2.
Problem is while watching videos at youtube the video stops after playing for 3-4 mins.
It displays the buffering indication but I can see there is no data transfer coz the LEDs of
my router shows no activity (not blinking).
At this point if I manually move the video progress slider to an advance time data transfer happens and the video starts playing again.
But after playing for some minutes it stalls again.
