Hello all! Here is what I have and this is what I want to do: 2nd Floor (iMAC with Internet connection powered with direct Ethernet connection from Cable Modem) I purchased an Airport Express with hopes of providing Internet to my Macbook on the main floor of my house. The Airport Express can provide ITunes coverage. I have a Panasonic stereo with a decent set of speakers and a Music Port. I purchased the necessary Stereo to Stereo cord to go from the Airport Express into the Stereo. Here's the question: seeing as the Airport Express will be plugged into a wall near the stereo, do I need an Ethernet connection in the Express? (or will it pick up the signal from the iMAC?) Will it work? I tried it and the unit keeps flashing amber. I was wondering if I set it up incorrectly. Will the Home Sharing feature work?
