After I shut down the PC, I used different tools to send out the magic package, but nothing happens. Any suggestion?

    Your card is supported, now to configure wake-on-lan:

    1. Install ethtool

      sudo apt-get install ethtool

    2. Edit /etc/rc.local to add this line before the exit 0 line:

      ethtool -s eth0 wol g

    3. Find out the MAC address of your network card (replace eth if with your interface name, eth0, eth1, ..):

      ifconfig eth | grep "HWaddr" | awk '{print $5}'

    4. Shutdown the machine. You should be able to wake it up using:

      wakeonlan your_mac

  2. You need to install ethtool by typing with root privilage:

    apt-get install ethtool

    Next step is to enable wake on lan in your system by typing:

    ethtool -s eth0 wol g

    I describe such scenario and few optional next step on my blog
