I had the same problems --
the solution was to connect tablet to power source
(or to disable power-saving in my tablet settings)
now it all works great! It seems that in power-safe mode and not connected to a power source the tablet is not listening all the time to incoming data, thus no respond/connection rest and connect drops.
I was using Samsung Galaxy tab 10.2 and Firefox as browser on Mac
