The past two mornings I have tried to access my iTunes library on my sleeping MBP (lid open) through home sharing. I have "wake for network access" enabled, and the ATV definitely recognizes that the library is there, but it won't connect. I tried using the remote on my iPhone but had the same problem-- I tap the fully lit iTunes Library icon, but the connection never occurs. Home sharing normally works really well. I seem to only have problems when the computer has been asleep for an extended period of time. My MBP is connected w/ethernet, running 10.7.3, and I'm using a new AEBS. Any suggestions for fixing this?
