Optiplex 755 Wake On LAN Not Working Properly - HELP!

This question is answered

Hello All,

I have been recently having issues with WOL not working properly.

I have the onboard Intel NIC WOL option enabled to ON within the BIOS as well as disabled the Low Power Mode, which is set to OFF, under Power Options and I am unable to boot up my desktop when I log into my router's WOL page to turn on where it used to work just fine.

The only way I am able to get it to work is when I power off the machine, detach the AC plug from the back and press on the power button to flush out any residual power, plug it back in and then try WOL on the router from another machine. After that, it stops working again. If I perform the same process (AC power flush), and boot directly to the OS, use it a bit, then shut down, WOL doesn't work again. Is there too much power being drawn causing it to fail? That doesn't make sense really... I would think the machine would just fail altogether if that were true...

Can anyone help me understand this further? Is the motherboard going bad? The PSU? Like I said, NO configration changes have been made on either the router nor the desktop. My BIOS is the newest (A20) and I even tried downgrading to A17, the same issue still persists.

Please help!

Thank you!

  • Magic Packets aren't transmitted in all routers all the time.

    WOL has been abandoned in favor of VPRO INTEL AMT

    I find that by enabling the PME setting in the Intel pro 1000 NIC allows WOL to remotely power on the computer.

    PME in the advanced settings in xp for the network card.

    WOL can stop working due to the PME setting being changed or added to machines through the driver updates.  

    In the adapters advanced settings, there is a setting titled "Enable PME."

    To explicitly allow wake up with a Magic Packet from shutdown under APM power management mode, set this to "Enable."

    In ACPI capable versions of Windows, there will also be a setting titled "Wake on Settings

    ." This controls the type of packets that will wake up the system from standby. Click the Help button in PROSet for a complete explanation.

    In ACPI computers running ACPI aware operating systems such as Windows* XP, in Device Manager,

    the adapter properties will display a tab titled "Power Management.

    " The setting "allow this device to bring the computer out of standby" should be checked.

  • Thank you SpeedStep for your in-depth response!

    I did see that I didn't have PME enabled, so I will do so:

    I did have "Only allow a magic packet to wake the computer" enabled. As a note, my operating system is Windows 7 Pro x64.

    Quick question, how would changing something in the network card properies in the OS allow for this to work, especially when the machine is being turned on from a completely turn off scenario. I can understand that these settings are important when the machine is in an S1-S3 state, but not when the machine is completely off?

    MANY thanks for your help. I'm going to try your suggested settings and report back.

    Thanks again!

  • I'm not a WOL Dell Engineer. So I don't have an answer.  I do know that unless the machine is un plugged from the wall it is never completely OFF.

  • Interesting. Thanks SpeedStep, once I test this out (most likely tonight), I will report back.

    Thanks again!

  • IT WORKED!

    Thank you SpeedStep!! It's interesting to learn that perhaps ACPI really does more than just automatic IRQ assignment and easy power off! :)

    Thank you very much again!

  • I have the same problem but my system runs Ubuntu server 12. I can set the system to go into pause but then there is no more keyboard power, no more mouse power and the magic packed does not work.

    I am sure I have set all the right parameters in the modem and in the systems settings.

    Can anyone help me, it is bothering me for many weeks now.

  • Hi martinschuurman,

    I'm sorry for the issue you are having. Unfortunately, I don't know much about Ubuntu coupled with Optiplex 755 workstations.

    If there is a forum for Ubuntu-based systems, please try asking your specific question there.

    Sincerely,
