    Wake Up On LAN

    Looking through my BIOS I see the wake up on LAN. If I enable that, and have a ethernet cable thats cut so there just an end - If I plug that in will it turn on my PC?

    Try it out and let us know. I have a laptop that has that, but it only works to bring the computer out of standby, not from a full shut off.

    No.

    WoL detects a signal on the LAN port, which means you would need voltage (albeit a tiny amount) on the Cat5.
    A cut off piece of cable isn't going to do it.
    Have you looked in the FAQ yet?
    How about the Wiki?

    I believe that signal needs to send the 'magic packet' in order to wake it up.

    I've seen people use an old router and have it hooked up to the ignition. That sends the packet when it wakes up.

    Yeah I'm thinking Wake On Link, not Wake on Lan

    Hmm, would it be a terrible idea to try and splice into the end of 1 end of the Cat5 to 12v ignition source, and plug the other end into my LAN in attempt to wake it?

    Does it need the magic packet, or just a small voltage from the line?

    I remeber seeing a picture of a guy with the router in his trunk doing this..

    Any idea how to set this up? Googled abit and tried to understand it...but im getting no where.

    I have an old linksys WRT54gs around. I enabled Wake on Lan on my bios. Read an article to forward port 9 to 192.168.1.255 (Which the router won't allow me to do). They mentioned this would happen so you need to setup ARP or something? This confuses me..

    I just want to be able to plug in ethernet from the router which has power...to start up my laptop. Seems I have all the necessary hardware...just don't know how to complete this!

    This would likely destroy your motherboard or network adapter, as the voltage from the car would be much greater than the network adapter could handle.

    Wake on LAN requires the magic packet.

    Here's a good resource on port forwarding: http://portforward.com/
    Don't know why the article said to forward a port to that address. That honestly makes no sense.
    I'm willing to bet that you need to forward the port to your PC, but I also haven't read the article.

    Figured it out..took awhile but I got it.

    The reason it you need to forward 192.168.1.255 is because thats the routers broadcast address. As a security feature on the linksys router, that port is disabled. So I upgraded the firmware to DDWRT, which has this along with a bunch of Wake on Lan settings.

    Enabled Wake on Lan on the router, and on my laptop. Inputted my MAC adress from my laptop into the router, put in the broadcast port. You can also change how often the router looks to see if the computer is active/in sleep mode.

    So...hook up router to my ignition. Router turns on, see's laptop is in Sleep Mode, router sends packet to laptop...takes it out of sleep mode. When I stop and about to turn my car off...choose sleep mode on the touchscreen. turn car off.
