Well, this if for my computer engineering degree proyect, and the target of this is to save energy by leting the PC off and only be ON when needed, but for all users(not every user knows how to do a Wake On Lan).
My first idea was to set a table inside the firmware from the router which contains "MAC, IP, blabla, time for booting, estade -on,off-". When the router detects a quest from master to client, it looks in that table, if it is off, the router itself wakes the client up, waiting that time from the table and letting pass then the quest. (of course i'd have to know that I may have to wait some time till my quest is answered).
I don't know if there is a easier way to do this, I'm open to any other ideas.
@humbledestroyer, I thing you got the idea more or less.
@Gumby the Magnifocent, I don't understand what you mean, can you explain yourself?
Thank you very much, this is the only place where I've received any answers due to the "weird" topic it is, thank you guys.
