Computers not waking if not shutdown be WOL

Open dcnewton76 opened this issue 6 years ago • 8 comments

Hi, If a computer is shutdown in the normal way it seems that WOL cannot wake it up.

To enable WOL, a lot of things need to happen. Your motherboard has to support it, and your network card. You have to enable it in the BIOS. You network card driver has to support it, and the operating system has to configure the network card to enable it.

If all these requirements are met, when you shutdown the computer, you should see the NIC activity light blink every few seconds as it is listening for WOL messages.

Yep, 7 are working but the rest of the room are not. it is when the computer is shutdown via the start menu that WOL will not wake it up.

Is the NIC light blinking after the computer is shutdown?

hi, yes the NIC light is still on

That's a good sign. Then log into the computer, run WOL, open the "listener" window. The listener window will display incoming WOL packets.

Now go to your controller computer, open WOL, and send a wake up to it. See if the packet arrives at the computer you are trying to wake up.

We do not have WOL installed on the remote computers, is this necessary for it to work properly?

You do not need to install anything on the remote computers.

I only suggested that for testing reasons. There is a "listener" function in WOL that will show you if the computer is receiving WOL packets.

Mmm. Windows 10?

The start menu shutdown function changed in one of the more recent Win10 builds and it is no longer a true shutdown. You will note that many Windows apps which were open before shutting down are open again when you start up.

Try shutting down this problematic machine using the command line:

shutdown /s /t 0

This should be equivalent to the long standing 'old' way to shut the computer down and roughly equivalent to a power-off event followed by a power-on event ... where WOL should be armed, waiting for a magic packet to arrive. Mostly, though not always on very modern machines, this is indicated by your NIC activity LED blinking even though your PC is in S5 shutdown.
