    I am using a debian kernel 2.4.18
    a nic 3com wol is installed in the machine
    this card is wake on lan
    it works but a problem occurs after I shutdown the computer
    It seems that when linux shutdown the computer it deactivates the power
    source of the nic and
    then makes impossible the wake on lan of this computer.

    Does anyone knows how to shutdown the computer preserving the power on of
    the nic card ?
    Thanks in advance

    .... and you do have the separate WOL cable installed from the motherboard
    to the NIC?

    Additionally, there might be some settings in your BIOS that control the
    power supply behaviour when the machine is shut down.

    no because it works with windows
    it is a problem due to the way linux shutdowns the pc

  4. that's awfully technical. Are you sure Windows isn't simply putting the
    computer in Standby? As Juha says, there should be a WOL cable (3-wire) from
    the motherboard to the Card, and it is a feature of the ATX / ACPI power
    system which allows this.

    I would definately check your BIOS. When the computer is powered off, the
    3com's link/activity light should still be active. Is it?

    the ATX / ACPI power system which allows this.

    you should check if WOL is enabled in your BIOS.
    normally you _MUST_ enable WOL in your bios first.
    then you _MUST_ use a 3header-WOL-cable connected to you WOL-plug on the

    when the lights of the 3com-nic are active when the computer is
    it should be possible to do a WOL to wake up this workstation
    btw. _HOW_ do you try to wake up this workstation ??
    maybe a problem with your software ???

    i don't think so - i use SuSE 8.2 and there is no problem with WOL...
