We have the following setup at home: *D-Link DI624 router, which doles out wireless to all of our home computers (3 laptops, 1 wired desktop, 1 wireless desktop). The oldest desktop is now obsolete, and we'd like it to be just a music server. In addition, we'd like to use Airport Express to stream music to the home theater system. How will this work? Can the desktop, which is wired to the D-Link router (and therefore part of that network) simultaneously send output to APEx? Can music be streamed from the desktop music server to a laptop (via the D-Link network) and subsequently from the laptop to the APEx (can the laptop send shared music to the Express?)? Also, if this isn't doable, how much if any would be solved by replacing the D-Link router with an Airport Extreme base station? Thanks for any help!
