I work at a University and have access to the Wireless campus-wide network. I don't have an Ethernet plug in my house. I purchased an Airport Express with the purpose of using it to play my music wirelessly. I have spent the past 3 hours working on this and no search has been able to help me. For some reason, whenever I select the option to Join Wireless Network, after it resets, the AX will not show back up in the Airport Utility. The Light turns green, and the speakers are plugged into the AX, but nothing shows up in iTunes or AirFoil. Any ideas?! I'd hate to think that this won't work. Thank you in advance!
