Wake On Lan from Shutdown Computer

This is my first time messing around with WOL and I can't seem to get things working.

I have a windows 7 machine with WOL support in the Bios.
It is enabled in bios, and I have not done anything in windows.

I have a client that will send magic packets, and a packet sniffer showing the packets are being sent.

The computer will not wake.

I was wondering if there was something I was missing?

everything is on an internal network, simply sending the packet to the adaptor address
trying on ports, 7,9, and 3000

this seems like it would be simple enough to do, but I can't seem to figure it out.
All I want to do is Turn on an computer from off power state to boot.

Any advice appreciated

Do you have PME enabled on your NIC?
Dont know if you have Intel NIC, but here is a link, might be usefull

You may also need to check for the latest driver for the NIC and check settings.

I guess this is one of the things I am trying to figure out.

The computer is off, therefore, I'm assuming anything in windows is irrelevant. So I have not looked at any windows configs.

I'm assuming, all the WOL is doing is sending to the shutdown computer, waking it, and booting until windows loads.

Or am I doing this wrong? because I would think anything I do in windows would be irrelevant when the computer is off, and that it's between the bios and the Magic packet.

You can give LogeMeIn a try.  Upon client installation you can choose to install a trial of their professional version instead of LogMeIn Free.  The Professional version has a WOL function included and so far, that always worked for me on various pc's.
Give it a try and if it works I'd say that you NIC settings are fine...

Connect further...control easier

With the ATEN CE624, you can now enjoy a high-quality visual experience powered by HDBaseT technology and the convenience of a single Cat6 cable to transmit uncompressed video with zero latency and multi-streaming for dual-view applications where remote access is required.

But that brings me to the same question.

if my computer power is off, and logmein is installed on windows, how do I access it
when the computer is off?

isn't this between the bios, and the WOL? I would not think windows nic drivers are relevant
in this situation

Welp,

I tried enabling WOL in the nic in win7, didn't help

I looked at the PME, but it's a realtek card and think it's using the generic win7 driver.
no PME options.

I still don't see the connection between windows and the power being shutoff.
unless WOL is only meant for sleep, and hibernate, and not Turning on a shut off system.

Using a few

Netscan
wakeonlangui
Wake IOn Lan Sender

And then monitoring the packets with
Wolsniffer

Seems to send the packet, but doesn't wake up :(

This is what I noticed,

If I put the computer to sleep, WOL seems to work

but if I shutdown the computer, WOL does not work.

Am I wrong to believe that WOL will work on a shutdown state?
is that not how WOL works?

I should also note,

in the bios
there is only 1 WOL option

it says: enable WOL/S3 Power

don't know if this is relevant but I thought I'd post it

For a windows machine.

Control panel network, right click on LAN card, properties, advanced

wake on magic packet: Enable
wake on pattern match: enable

power management tab.

check
allow this device to wake
only allow a magic packet to wake

(not all options are available on all computers)
turn the computer completely off full normal shut down, not sleep mode, verify that the LAN card HAS LED's ON. The computer must be in a clean shutdown state or it will not wake.

OK,

Looking at the machine after doing a windows shutdown,
I notice that the ethernet light is not flashing. meaning it is not getting power when
system is shutdown.

I am assuming that this means that the hardware does not support WOL when system is shutdown.

If anyone knows different, advice appreciated.

if the LED's  do not light after shutdown either the HW doesn't support it (very unlikely) or one of the BIOS settings are incorrect  (likely) what is the exact make/model of the hardware, comupter and NIC
