Check if your interface has support and if the BIOS configuration is OK. ethtool ethx | grep -i 'support' hamilton@saygon:~$ sudo ethtool eth0 | grep -i 'support' Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full Supports auto-negotiation: Yes Supports Wake-on: pumbg Available options are: wol p|u|m|b|a|g|s|d... Sets Wake-on-LAN options. Not all devices support this. The argument to this option is a string of characters specifying which options to enable. p Wake on phy activity u Wake on unicast messages m Wake on multicast messages b Wake on broadcast messages a Wake on ARP g Wake on MagicPacket(tm) s Enable SecureOn(tm) password for MagicPacket(tm) d Disable (wake on nothing). This option clears all previous options. If "g" option is not ok, please run: ethtool -s eth0 wol g Get your MAC addrees before rebooting: hamilton@saygon:~$ ifconfig | grep HWaddr eth0 Link encap:Ethernet HWaddr 00:1c:c0:c3:ed:fd To wake your PC, make sure that you are running this command from another PC inside the same network etherwake 00:1c:c0:c3:ed:fd
