Hello,
I recently setup a wireless network using the Linksys WRT54GS router, but after trying to use AirTunes via Airport Express I wasn't having any luck. I just moved into a house at school, and brought my Airport Express to use in the new house. After fooling around with it for a few hours and only getting a blinking yellow light, I finally gave up and decided it might be defective (I hadn't used it a home in a few months). So I tried it when I got home, and it definitely wasn't defective and was working perfectly fine through my setup at home. At home and at my new place I am using the Airport Express strictly for the AirTunes feature. If someone could offer me any insight as to why the Airport doesn't seem to work with the WRT54GS, that'd be very helpful. Thanks a ton.
