    Default Won't wake up on LAN Access

    I have a small network with several computers connected via Cat 5 and other appliances connected wirelessly.

    My main system has an AsRock Fatal1ty P67 Performance Mother Board. In Windows 7 Home Premium, the system will not wake up when access is attempted from other machines on the network. The system is correctly accessible when awake. The problem occurs either when put to sleep by the power settings or by user interface (sleep button).

    This is a dual boot system, and does wake up when booted to XP SP3. This implies that it is a W7 problem, but Iíve included my bios settings anyway.

    In Bios: (only things I found that reference LAN)
    Under [Advanced\ACPI Configuration]
    PCI Devices Power On = Disabled
    Under [Boot]
    Boot from Onboard Lan = Enabled

    For Windows 7
    When in sleep mode, there is no light emitting from the NIC card.

    the NIC is an on board, Realtek PCle GBE Family Controller

    In device manager, On the NIC Power Management Tab, it doesnít seem to matter what settings are selected. Iíve tried these. There arenít any NIC lights in any of these settings when in NIC mode.

    Note that you canít select [Allow this device to wake the computer] unless the first choice is also selected.

    [ ] Allow the computer to turn off this device to save power
    [ ] Allow this device to wake the computer
    . [ ] Only allow a magic packet to wake the computer


    [ ] Allow the computer to turn off this device to save power
    [x] Allow this device to wake the computer
    . [x] Only allow a magic packet to wake the computer



    [x] Allow the computer to turn off this device to save power

    [x] Allow the computer to turn off this device to save power
    [x] Allow this device to wake the computer
    . [x] Only allow a magic packet to wake the computer

    Windows reports that I have the latest drivers.

    My power management settings:
    Sleep after
    . Plugged in: 40 Minutes
    Allow wake timers:
    . Plugged in: Enable
    PCI Express
    . Link State Power Management
    . Plugged in: Off

    I appreciate any help offered.

    You need to select "PCI Devices Power On = Enabled"

    The power management settings in Device Manager quoted above are correct.

    You need to go into Device Manager and the Details tab of Properties for the NIC. Look for options to enable wake on lan and wake from shutdown.

    Whatever utility you are using to wake up the pc will need the MAC addresses of every machine you want to wake. You can get those by running a cmd prompt and ip config /all.
