http://www.tuaw.com/2009/08/29/snow-leopard-extends-wake-on-lan-feature-if-your-config-is-ri/ The sleeping Mac stays visible on an Apple router because the Apple router kindly takes over the Bonjour advertising for it. No non-Apple router will do that, at least until you get into the Cisco or Mikrotik programmables. Good description of the process here: http://revolutionwifi.blogspot.com/2010/11/wake-on-wireless-lan.html One corollary is that this feature requires the wireless card to use power even when the machine is asleep, meaning that if you leave your Airport on and your AC disconnected, you will drain your battery faster even if you leave your laptop sleeping. -- Macs R We -- Personal Macintosh Service and Support in the Wickenburg and far Northwest Valley Areas. http://macsrwe.com _______________________________________________ MacOSX-talk mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-talk
