The only two methods that keep Wi-Fi hotspot working are either keep phone on 
charge or make sure the screen never sleeps.  We all know the Wi-Fi sleep 
policy doesn’t work so I have found a great solution for this problem and it 
does work.   WEE PEE!!!  Download a simple app from the android market called 
‘Wake Lock Power Manager’  It seems to be the only working solution in the 
world.  Here is the link -

I have the same problem. I've downloaded the "Wake Lock Power Manager", and 
installed it. I configured it to start up at boot. Which setting do you select? 
By default it is 0 or no lock. Is that correct? If I select Full, then Tether 
doesn't work.
