Okay, I admit it, I own a PC, well several.. But I do love Apple products, iPod, iBook, and now the Airport Express - sorta. I have an existing Wireless network running a a linksys router. My computer (PC) is connected to that router through cat 5 cable, but there are some wireless PCs connected to the router, mine isnt one of them. I have iTunes on my PC, and I wanted to stream it through my router down to my stereo. So I bought Airport Express assuming I could do this (I still think I can). Anyways, my setup looks like this: Anywhoo, I plug in Airport Express to the wall like the instructions say, and it can't detect my network, or will not connect to it. It just flashes amber. Now, it is in range (its in the same room) and I disabled mac filtering just to make it easy for it to connect, and even disabled WEP... No such luck. It will not connect. And when I open that Admin program, I try and put in the IP and password for my linksys router but I get a "-4" error or something, basically it can't collect the settings. Now I can connect to the airport express to some extent. I installed the software on my wireless computer and it does detect the APE as a network so I see mine, my neighbours and stuff, then teh APE. I did connect to it on that computer but I believe that it was thinking I was using it as a router, when all I want it to be is a client. This is very frustrating and I'm hoping one of you guys could help me out!
