I have a Sky router plugged into the wall, and an Airport Extreme plugged into that. Unfortunately I cannot get rid of the Sky router as it is the ADSL modem so I'm stuck with this unfortunate setup. I have a MacBook Pro and an iMac and they used to be able to wake each other up automatically but this stopped when I plugged the iMac into an ethernet port on the Airport Extreme instead of connecting wirelessly. Is wireless wake on lan not compatible with wired wake on lan or something? I thought the Extreme monitored the DHCP leases of each device so it knows exactly where to send the wake up request packet, regardless of whether the device is wired or wireless? I realize that yes, it all works wirelessly but I'd like the option of having the iMac wired to the Extreme as I'm thinking about connecting a NAS drive to it soon. Any help would be much appreciated. Cheers!
