As you usually are -- right again. There has been no other noticable connectivity issues with my TRENDnet router. There are transmit errors which self correct from the tablet -- might they also relate to power management? In a simple sense it seems that the tablet will shut down the radio for 200ms or 1sec whenever inactivity is experienced. The access points roll may then be to understand via the protocol that power saving is on and to extend timeouts to accommodate the tablet radio power down periods. The application on the other end would need to adjust timeouts as well but, it appears that ping assumes constant connection and therein lies the disconnect. It would also seem that the power saving protocol is last mile in nature and not end to end -- on this I'm not sure. Is there an RFC for the protocol to settle my software engineer's curiousity?
