    Ok, title says it all but it does not seem to work that way.

    I try to access my second computer using Timbuktu on a LAN and the computer wil not wake up. Both computers are connected wireless (Airport) through a router....maybe this is the issue? Option in Energy Saver panel says "...ethernet network access..." and I'm going Airport.

    Any suggestions?

    TIA

    correct

    "Wake for Ethernet network administrator access" is a longer way of saying "Wake-On-Lan."

    it's designed for wired ethernet connections. it's supported because the ethernet network controller is built into the motherboard.

    the concept is simple: even with the computer off, a little power is still running to the network controller. when the network controller receives a packet ("magic packet") the controller sends a signal to the bios and the computer starts up.

    additionally, just trying to connect is not sufficient. you need to send a "magic packet" which is just a fancy way of saying you need to attempt a connection on a specific port (0, 8, 9). if you do wire your computer you can download a pretty cool tool from http://www.readpixel.com/wakeonlan/ that will enable you to wake the computer.

    feedback please, about effect of checking "wake for ethernet net admin access"

    i shut down my mac pro each night; everything is off, monitor is asleep, amber light.
    i come in next morning, and machine is running (actually it's got a gray monitor screen, indicating the boot up didn't load all the Leopard system).

    this mac pro is wired with ethernet, from a router that takes its incoming signal from an ATT DSL line. one other machine is ethernetted on this router (the router is a linksys with four lines out, and wireless signals).

    i suppose somehow a "magic packet" is coming to my mac pro in the deep dark of night, and waking it. is this a certain explanation?

    i have not loaded any packets, or configured my network to do any waking functions.

    and i will un-check this irritating 'convenience' of waking if i determine my above explanation is correct.
    thanks for any computer goo-roo assistance on this "energy saver" issue.
    michael
