This is a shot in the dark to ask here, but can anyone help me with a Wake On LAN problem? I can only wake up my PC within five or ten minutes of having shut it down. It's going into an S3 state, the driver is set to Wake On LAN, and I've set the BIOS just like the instructions say to wake from S3—I can't work out why it goes into a deeper sleep, essentially.
I know the magic packet gets there because a) it works shortly after shutdown and b) I've run a packet sniffer. I've also tried to wake it from different devices, and it only works within a short zombie window.
(I'm trying to set up an NFC tag so my phone can wake up my PC with a tap of my key ring, and then my PC can take actions based on polling Dropbox folders)
