I have recently changed my Airport Base Station for an Airport Express connected to an iMac G5, since doing so whenever the mac is put to sleep the airport also goes to sleep this never happened before. It is only a matter of going to the drop down menu and reselecting our network set up, this does not bother me but irritates the hell out of my husband having to do this, has anyone any ideas where the option to change this is, my husband is driving me to despair with his moaning!
