I think this is wierd in any way because if ONE station= =20 with powersaving on could set the AP in DoS ... man ... if really true this= =20 is kind of lame excuse or kind of driver weakness which both would be=20 inacceptable, and, if it does NOT wake up if in sleep state ... no further= =20 comment, but a driver weakness right? wether powersaving is on or not on the station/client is a local setting t= o=20 this station and must not influence any remote computer in any way, imagin= e,=20 you turn on your powersavings and the complete internet goes down on your=20 request hihihihi :) but then, like my case, on the AP or better ath in ap mode, even IF=20 powersaving is ON it might stop working for any related reason but firstabl= e=20 NOT WHILE TX/RX and secondable if idle it must return soon THIS computer=20 wants to transmit any kind of traffic again last but not least powersaving might shut the power down but must return w= hen=20 necessary - if not - there is a driver problem.
