Can't see airport express in airport utility
Just purchased an airport express to add to my network for the purpose of steaming music wirelessly. The network already has an airport Extreme as the base and four other expresses wired via CAT-5e in an distributed network that is working great. I had one other room that I wanted to stream music without running additional CAT 5e. I cannot get the express to show in airport utility so I can configure it.
Computer: I-mac OS X 10.8.4
airport extreme: bridge mode with 4 expresses underneath in bridge mode
Do have a verizon router above the extreme (FIOS) but the wireless is turned off
AirPort Extreme 802.11n (5th Gen), OS X Mountain Lion (10.8.2)
