    Wake On Lan not working on Windows 7

    Since moving to Windows 7, our PCs no longer wake-on-LAN. From other posts, I suspect this is a BIOS/power management issue, but can't find the setting which has changed. The NICs are still powered, as the link lights are still on (both on the PC and the switch), however they won't respond to WOL signals. Any offers how to resolve this?

    Is it enabled in the driver settings?

    Driver settings look good, and there's nothing in that other thread which helps.

    Have you tried installing the full driver software package including the intel management software.
    To test if its a software issue boot into your bios, disable and re-enable WOL. Save the changes and shut down the PC - before windows has a chance to boot turn the PC off try and wake up the PC. if it wakes up its windows Turing it off when it loads.

    Windows Drivers can make changes to it, including power/WOL settings once it's booted up.

    Therefore it's not unlikely that when you set WOL in the BIOS, windows changes it back when you boot it up.

    WOL is enabled in the BIOS, and the drivers are set to allow it as well. Our RM PCs (Intel boards, Intel NICs) still have the link lights on, but the Stone PCs (Intel boards, Realtek NICs) don't even keep the link lights on. Not sure what the HP computers do, I'll go check one.

    There's a tonne of posts online from people having the same problem as me, some of which seem to be resolved with driver updates and some don't.

    Dear Mr.Ben,

    i do believe you have been misinformed!

    The only things you can do form windows to the BIOS is 1)change date and time 2) updating the ROM.

    so let me clarify windows can not edit the BIOS or change settings

    @r_soles - So rather than just insulting and criticising some very experienced IT professionals, and thus proving the appropriateness of your chosen nickname, I invite you to make a positive contribution to this discussion and suggest some other reasons why WOL stopped working the day I installed Win7 on a PC.

    R.soles, sums you up!

    I think you will find that Mr. Ben and I are correct and it is you who are wrong.

    Have you tried everything on this website: Windows 7 Issues: Wake-on-Lan (WOL) for Windows 7 Made Easy! ?

    Top result on Google, so I assume you've looked. Does strike me that surely you would need to turn off "Allow the computer to turn this device off to save power", but still...

    @simpsonj thanks, hadn't actually seen that, your search terms must have been different to mine.

    It didn't work, though. I am a bit confused about the firewall bit though, as I can't make sense of whether the Windows Firewall is on or not. Screen shot attached:
    firewall.jpg
    So, it says the firewall is off but then says that unapproved connections are being blocked - don't get how both those things can be true....

    For WOL to work:

    Enabled in the BIOS (if the option is there)
    Eabled in the driver (with magic packet turned on, WOL enabled)
    Enabled on the power management settings for the card.

    These days the windows drive sets the state for the card when you shutdown the machine to make it listen for the packet or not.

    It also may not wake the machine from sleep or hibernate depending on what the driver did. Some windows 7 supplied drivers do not work correctly with WOL (like intel ones).
