Someone help !! Running unRaid 5b13 with Sf 0.9f on H61M-E23 (B3). It supports S1/S3 and few ACPI 2.0 options.

 

WOL is not working everytime with it.

 

If I force the machine to sleep... and send magic packet after few minutes.. it will come back.

If I force the machine to sleep... and send magic packet after 30 minutes.. nothing happens. Using http://magicpacket.free.fr/ from windows 7 machine. Help !!!!!

 

Also, is there any WOL tool for mac?

as I said earlier, after waking, many network cards must be reset with something like this before they will listen for another WOL packet.  Many will need their speed reset too.

After waking, type

ethtool eth0

to see what is set.

If you do not see

Supports Wake-on: pumbg

        Wake-on: g

then you need to set the "wol" option as below.  If you do not see the speed as 1000Mb/s, you need to set that too.

 

# Do post-sleep activities, reset wake-on-lan

ethtool -s eth0 speed 1000

ethtool -s eth0 wol g
