Well, if you are speaking of a laptop, then yes, mine disconnects (or Network Lock activates) until it wakes up. I was told way back when that this is normal. On my iMac, it will do the same thing if I allow the hard drive to sleep. If I don't allow it to sleep and only use my screen saver (on iMac) then it's fine and it d/l's in the background. Unfortunately, I only really use my MacBook Pro for emergencies, like if my iMac dies or has some kind of problem. If there is a simple workaround on a laptop, I don't know what it is. Anyone else??
