I'm trying to setup an Airport Express. I can _almost_ get it to work, but not quite. I can get it to work wired to my network, but I need it wireless. I am trying to stream itunes via airplay to some powered speakers. I have a linksys wireless router, an older version that does not have 'n'. The apple setup manual makes it as simple as plug and play and the speakers will show up as speakers in itunes. If I try to do it without a network wire pluged into the AE, it never gets recognized. Once I plug it in, it shows up in my wi-fi/network setting and I can set it up and get it to work. Not sure what I'm missing. Is it an issue with my linksys wireless router? What else could I try?
