Wake-On-Lan Random Wakes

Postposted on Mon Jan 30, 2012 9:44 pm

I've recently implemented WOL on my same machine on Win7 32-bit and have since reformatted/installed Win7 64-bit and also added a wireless printer to my network. Since doing this, I've reconfigured the same port-forwarding, firewall port opening, WOL power-management setup, and network configurations (I use dynDNS to affix a permanent address to my dynamic IP). Although the ability to remote WOL seems to be sporadic (at best) - sometimes it works, sometimes it doesn't... what's particularly annoying is that at times it will wake without issuing the magic packet to the MAC/address.

Now, I'm not sure what exactly is causing this - since upgrading to Win7x64, I did introduce a new wireless printer... however, I set the LAN card to "Only wake with Magic Paket", and so this doesn't seem like a plausible explanation. Windows event viewer provides no detailed information on LAN system events that I could decipher.

Is there any opensource/freeware network event logging software that will track what exactly is going on when my PC is being awoken in this situation (e.g. show where the magic packet is coming from - what external or internal IP address to determine if it's something on my network or a remote ping). Any ideas as to what's waking my PC (it seems more likely that's it's not a third party trying to wake my PC, but something going on with the PC/LAN card or something on my internal network)

EDIT: I found an option within power management that says "Allow Wake Timers", and it was set to ON; I changed it to off. Anybody know how this setting behaves and if it's the culprit?
Also, I found the event under windows, system (event-log) with event-id 1:
The system has resumed from sleep.

Sleep Time: ‎2012‎-‎01‎-‎30T05:52:06.655010100Z
Wake Time: ‎2012‎-‎01‎-‎30T19:59:35.707126200Z

Wake Source: Unknown

Unfortunately, this doesn't help me, as the wake source gives no info.

About all I can suggest is make sure it is definitely set to magic packet and not any LAN activity - there may be a bug on that setting in the drivers, try switching around and see what you can wake it up with. Also go through the BIOS and make sure none of the other settings are on for wakeup.
