With Lion wake up on wifi doesn't work on my 2010 Mac Mini
With Snow Leopard my Mac Mini was waking up automatically as soon as I browsed to one of their discs from my 2009 MBP (also loaded with Lion).
With Lion installed on my Mac Mini I have to wake up it manually. Not even time machine wakes it up automatically (I use a USB disc attached to the Mac Mini to backup my MBP).
How can I enable the wake up on LAN (wifi) feature? I didn't find any option to do so.
Thanks in advance.
Mac mini, Mac OS X (10.6.7)
