I had a difficult time tracking this one down… it seems that when I tried to wake my computer using Wake on Lan, it stopped working and at first I didn’t realize why it had stopped working. I’ve narrowed it down to the winpkfilter driver– when it is installed, SOMETIMES wake on lan doesn’t work. The lights on the back of the network card actually just turn off when the computer goes into standby instead of staying on and listening for the wake on lan packet.
I did some searching around on the net and read that intermediate filter drivers like winpkfilter can break things like wake-on-lan.
Are you aware of this issue? Is this something you would know how to fix?
