I'm having EXACTLY the same problem: AP Express connected to existing wifi network.
Everything's set up properly:
- AP Express connected to the wifi network
- recognized by the router (GlobeSurfer II)
- recognized by iTunes
I get a beachball when I try to play music through AP Express via iTunes... it spins for maybe a minute and then goes back to computer speakers.
The weirdest thing is that a friend brought her AP Express and we set it up in 2 minutes and it worked like a breeze!!
Another thing: when I set up AP Express as a standalone wifi provider with its own network it works perfectly!
Firmware is 6.3 so this is definitely not a problem. Who's crazy here?
