Please follow below steps to configure your G41T-M6 system:
1. Access CMOS Setup to set "Resume By PCI/PCI-E/Lan PME" under "Power Management Setup" to [Enabled]. Then save this change & exit BIOS.
2. Load OS (here we take Windows XP as an example) & go to "Device Manager" to right-click the "Atheros AR8131 PCI-E Gigabit Ethernet Controller" of "Network adapters". Then come to "Power Management" under "Properties" to "check" [Allow this device to bring the computer out of standby.] & hit [OK].
3. Swtich to "Advanced" of "Properties" & change the "Shutdown Wakeup" from [Off] to [On].
Once you finish all the procedures listed above, you can use Magic Packet (downloaded from below URL) to wake up your system from a subnet different system.
