Noone has ever said having power > save enabled in client sta's should be permitted to cause an ap to stop > proper operation. > hum, but that is exactly what it ever appered to be I relate a problem, in this case the AP stops transmitting I get answers that there are power management issues on a client station so what I did misunderstood here? .... > > I guess you still don't understand what 802.11 power save operation means. > probably right but I am not sure if I need to, this must be understood by whom writes the driver I guess and who writes the driver should take care of that the AP does not buffer packages endless until itself dies at the end with full buffers I believe that the ath driver when in hostap does not know that a sleeping remote card is away for ever because it does NOT clear it's own buffer until reboot/reload. I do not know why but I believe it does not send or read the beacons to this sleeping station (I believe the AP should send a beacon telling the station there are buffered packages), then when the station does not wake up then the AP should discard this packages but it does not and over the time the ath buffer fills up until then OACTIVE happens and the card is gone ... as well as the AP :) anyway this is another hot problem but not related to the problem of this thread -- Joćo A mensagem foi scaneada pelo sistema de e-mail e pode ser considerada segura.
