If your tablet is actually holding a WiFi connection, then that means that it is on, but won't wake up. The only issue I see is that the green Charging Icon that you mentioned doesn't typically appear when the unit is on and charging. The first thing I would try is to hold down the power button for about 10 seconds, which should power down the unit, if it is on, then try to power it back on like normal.
On the other hand, are you sure the unit is on-line? My linksys router registers any component that attaches to the network and, even when not connected, displays all the units that have attached before. So make sure that you are actually seeing your device on-line and not just an image of the registered devices.
Keep us updated,
