Error message "Wake up failed".
I regularly use Wake on Lan on my PC to wake it up from sleep when I'm not at home but for a few days now it doesn't want to work anymore: when I click on the "wake up" button I get a message saying "Wake up failure [PC name]".
However, I don't seem to have touched anything and it seems to me that the settings have all remained the same on my two PCs (I have redone the instructions to activate the WOL and everything seems correct)
Do you have any ideas on the source of this problem?
Thanks in advance
