I trying to figure this out. I have Brother printer hooked up via USB and optioned as "share on network", I use The AirPrint Activator app for wireless iOS printing, and use Team Viewer HD app for remote access. All they things function perfectly when my mini is awake, but none work when it's asleep. I have selected "wake for network access" in the System Prefenances. Also, my router is a Xfinity supplied SMC-D3GNV gateway. Any ideas?
