18:54:56 <hyc> I found why my macbook always has so many bad hashes when mining - the OS has aggressive energy saving policy. it periodically put my wifi interface to sleep.
18:55:42 <hyc> whenever that happened, it would cause a delay in submitting a share, and the share would be invalid by the time the interface woke up again
18:56:14 <hyc> I just got a USB hub with gbit ethernet, plugged that in. no more of those errors
18:56:40 <hyc> but macos tries to put the usb to sleep too, need to keep an active terminal session running to prevent that.
18:57:26 <hyc> turning off the "go to sleep when display goes to sleep" option in battery control panel doesn't prevent it
18:57:46 <hyc> dunno where else to tweak energy saving settings
20:17:52 <DataHoarder> Unscheduled energy savings on wifi network?
20:18:00 <DataHoarder> UAPSD afaik or similar 
20:18:25 <DataHoarder> if enabled/disabled it changes how wake up is handled by connecting clients
20:18:43 <DataHoarder> Needs to be changed on access points
