Wake On Lan: Sleep/Hibernate - Works, Shutdown - Not

post #1 of 14
Thread Starter 
After reading countless posts and playing hours with BIOS settings and my network adapter I gave up and seek help!

So topic says it all. I managed to make WOL work (both over internet and LAN) when my PC goes to sleep or hibernate but when it's shut down, WOL doesn't wanna work.

Any suggestions? Thanks in advance!

leave it in sleep mode..

I've used it a couple times, form sleep mode. I don't have the skill to re-configure my GRUB boot order to allow windows to take precedence in the boot-order. Or at least I don't care to learn.. I'm sure the answer is out there..

To be honest i dont think computers can wake on lan from a complete shutdown, only through standby and hibernate, where the computer is in a low power state but still monitors usb ports and lan ports for any event that will wake it.

I didn't spend much time investigating, but when I wanted to do this, I too only had luck bringing it out of sleep. No luck when it's completely off.

Yeh, I guess it is so... It's just weird that some websites say that WOL can bring a PC online from shutdown and none of them actually said how to do it frown.gif

I also couldn't find any option in my BIOS that would shut my PC down to such a state when WOL would be possible. However, when I shutdown, there is a green led on my mobo, which indicates that it is in soft-off mode.

I guess hybrid sleep is good enough then. Will stick to it.

I'm just to lazy to search for the answer... Anybody...

Quote:
Troubleshooting magic packets
Wake-on-LAN can be a frustrating technology to implement. This is because it requires appropriate BIOS, network card and, sometimes, operating system and router support to function reliably. In some cases hardware may wake from one low power state but not from others. This means that due to hardware issues the computer may be waking up from the "fully off state" (S5) but doesn't wake from sleep or hibernation or vice-versa. Also, it is not always clear what kind of magic packet a NIC expects to see.
In that case, software tools like a packet analyzer can help with Wake-on-LAN troubleshooting as they allow to confirm (while the PC is still on) that the magic packet is indeed seen by a particular computer's NIC. The same magic packet can then be used to find out if the computer powers up from an offline state. This allows networking issues to be isolated from other hardware issues. In some cases they also confirm that the packet was destined for a specific PC or sent to a broadcast address and they can additionally show the packet's internals.
In Windows Vista and higher, you can also determine how the OS was powered up. You can use powercfg /lastwake in the CMD prompt and it will list the "Wake Source". The Wake-on-LAN event should also be logged in the System event log.[10]

from Wiki, it says it might not work for fully shut down devices for some hardware

Thanks, Thedark! It's funny how I overlooked it on wikipedia although I read it. It's just weird that it won't work for me. My mobo is not that old so I expected it to be able to boot from any state, not only standby/sleep/hibernate.. frown.gif
