I would like to use my Airport Express to stream music from my Mac Pro to my stereo system speakers. I already have the monster cables. Before I could do this I had to configure the AExp to join my current wireless network. I successfully updated the AExp settings, waited for the AExp to restart, and I got the message "Airport Utility was unable to find your AirPort wireless device after restarting." I did this several times, but I kept getting the same message. I would appreciate any help. (BTW, I am new to this forum.)
