I have an Airport Extreme and Airport Express at home. The extreme is hooked up to the internet (my primary wi-fi network) backs up my Mac mini, etc... I want to hook up the Express to my home stereo so I can use Airplay to play music. Can I use the Express to connect to the Extreme's wi-fi signal to make that work? I tried it using the Airport software and could not connect to my stereo. The only way so far that I can make it work is to make the Express a completely separate network (that isn't connected to the internet). If I do it this way I have to manage which wi-fi network I'm on at home and I don't really want to do that. Any ideas to make this work? Hopefully what I said makes sense. I can elaborate if I need to.
