Windows 7: Wake on LAN not working Windows 7, but ok Win2K3

Wake on LAN not working Windows 7, but ok Win2K3


I have a PC that I originally had Windows 2003 on. With Win2K3, I can send a wakeonlan (magic) packet (WOL) and get it to power on remotely from my home network/LAN.

I just installed Windows 7 Ultimate 64-bit, in a dual-boot configuration, i.e., so I can boot the machine to either Windows 7 Ultimate 64-bit or Win2K3.

As mentioned, I can power the machine up remotely (from my home network/LAN), but if I've LAST booted into Win7, then shutdown, it doesn't respond to the WOL packet.

I've confirmed that if I boot into Win2K3, then shutdown, the WOL works fine.

I have another PC that has both Win2K3 and Windows 7 (also dual boot), and that works fine with WOL.

One difference between the one that doesn't work vs. the one that works is that the one that works is a machine that I just built a couple of weeks ago, which uses an MSI 880gm-E43 motherboard.

The one that doesn't work also has an MSI motherboard, but it's an older one, an MSI K9NBPM2-FID.

I've cross-checked the various Windows power management settings between the one that works, and the one that doesn't work, but I just can't get WOL to work with Win7 on that older machine. I've even turned the Windows Firewall off completely on the machine where WOL isn't working, but no matter what I've tried thus far, no joy ...

The only thing that I can think of is that the network card driver (it's the MS one, from the Win7 distribution) might not work with WOL, but I've checked, and it's the latest driver from MS (Nvidia Nforce Networking Controller - 10/17/2008 -, and MSI doesn't have a specific Win7 64-bit driver for this motherboard.

So, I was wondering if anyone has any ideas about this?

Is there some registry setting or something that might allow WOL to work?

Thanks in advance,

Windows 7 32bit



Just for the record, I got WOL working with the older machine, JUST after I posted the original msg.

Here's what I did:

- I was in Device Manager, and did Update Driver, but
- I selected to let me choose, and then I checked the "Show Compatible devices" checkbox

Then, a 2nd, older (10/6/2006 - driver appeared, so I figured, "what the heck?" and tried that. I then shut the machine down, and sent a WOL packet to it, and kind of forgot about it (machines in a different room), but a few minutes later "bing!", the machine had powered up and booted into Win7!!

Anyway, as I said, for the record, and hope that this helps someone in the future.

I've got a junky old Gateway running W7 Home 32 that I got working by enabling S1&S3 in the BIOS.
