I've set up WOL on my computer at home on monday and it worked perfectly.
But yesterday I've noticed that it was hard to take remote control on my home computer. I connected to my router admin page and I saw that the computer was turn on because it was connected to LAN (so it seems that the wake-on-lan magic packet had work). Although, it was impossible to take remote control on it. I've however succeed but I don't know how (computer suddently been available).
Today, same problem : impossible to take remote control on my computer. However, the computer isn't awake regarding router information.
