I finally got my home theater system last week, and last night I completed it with an Airport Express, purchased solely for the purpose of streaming music. I got the AE all setup and then installed the new firmware. Turns out it was a very timely update, since one of the new features is the ability to turn off wireless and use ethernet only for music streaming. Perfect for me, since I wired a couple ethernet jacks to the family room for this purpose. Good job, Apple! So I have it configured with wireless totally off, static IP/router on my internal network. Everything works great. Streaming music is awesome, especially with the digital optical connection to my receiver (for anyone who wants to do this, don't buy the overpriced connection kit from Apple - save yourself $30 and get a cable from Radio Shack, works great). My music never sounded so good! But here's the weird part. The light on the Airport Express continually blinks amber. According to Apple , this means: But it did get an IP connection, it has a path to the router (not that it needs one, since it's for internal use only), ethernet is plugged in... Just a bug in the new firmware? Any ideas? Of course I don't really care as long as it keeps on working. Just weird. So far so good with the tunes, knock on wood!
