Does WoL work over a wireless network?
Yes and no. The WoL magic packet can be sent over a wireless network with no problem. For it to actually wake a sleeping computer, however, that computer must be connected to some part of the network via ethernet. This is because the ethernet card stays partially powered up when WoL is enabled, listening for WoL packets. The same is not true for wireless cards; they are completely powered down when a computer is asleep, and thus cannot receive any incoming packets. As an example partially wired / partially wireless network that can work with WoL, imagine a wireless hub (such as an Apple Airport Base Station) that serves both as a wireless access point and as a router, distributing IP addresses to different machines on a local subnet. A Squeezebox that is wireless connected to this hub can send out a WoL magic packet, and it will be received by the hub, which will then pass it on to other machines on the local subnet. If the sleeping computer running SqueezeCenter is connected to one of
