Wake on Lan WIndows 7



  • This makes no sense, but I promise that this is the pattern. I have had all of my computers scheduled to WOL daily at 7:00 AM. I have about 40 that we have upgraded to Windows 7. That is the only change. Once they are upgraded to Win7, they no longer Wake up. XP machines still wake up, but win 7 do not. I see no way that the OS could affect this, because the WOL is at the BIOS level. Any suggestions?



  • Thanks. We will work through this and come up with a solution!

    You may need a bios update, my windows 7 machines needed an update in order to turn on the functions for WOL with Windows 7.

    I know you probably don’t need all of this but give your settings a review, this is a walkthrough I set up for some of the things we use in our corporation, like PXE boot and WOL.

    How to Enable Windows 7 WOL (Wake on Lan)
    [B]WINDOWS 7[/B]
    Right mouse click [U]My Computer[/U] and click on [U]Manage[/U], then [U]Device Manager[/U] in your left panel. Find [U]Network Adapters[/U] and expand it to reveal your Network Card, right mouse click your network card, and click [U]Properties[/U], then the [U]Advanced[/U] tab.

    Energy Efficient Ethernet - Enabled
    Shutdown Wake On Lan – Enabled
    Wake on Magic Packet – Enabled
    Wake on Pattern Match – Enabled
    WOL & Shutdown Link Speed 100 MBPS (Only if you have problems getting the computer to receive the packets)

    Now click on the [U]Power Management[/U] tab.
    Check “Allow the computer to turn off this device to save power.”
    Check “Allow this device to wake the computer.”
    Not necessary but if problems persist, check “Only allow a magic packet to wake the computer.”

    Boot into computer bios

    [B]BIOS[/B]
    Click the [U]Advanced[/U] tab
    Choose [U]Integrated Peripherals[/U] and press enter.
    Lan Rom Option – Enabled
    Press Escape

    Choose [U]Power Management[/U] and press enter.
    EUP 2013 – Disabled
    Power Loss – Last State
    Press Escape

    Choose [U]Wake Up Event Setup[/U] and press enter.
    Wake up by – BIOS
    Resume from S3 by PCI/PCI-E Device – Enabled
    If you are STILL unable to get magic packets to wake computer, log back into Windows 7, go to [U]Control Panel,[/U] click [U]Programs[/U], click on [U]Add or Remove Windows Components[/U], place a check next to [U]Simple [/U][U]TCP[/U][U]/IP[/U] allow to install and reboot.



  • I had not seen that screen before! All boxes were checked, but I will work with various configurations over the next few days and see if any of those make a difference. Thanks



  • In windows 7 I found this option. It is listed when you configure the properties of the NIC.
    The only time we have gotten it to work in windows 7 is with the Magic packet box checked. However I have not tried the top box to turn off powersaving. This may be a fix also.
