Hi, First post, so bear with me. I have recently purchased an iMac and it's connected (hard wired) to my Netgear D834G router (this acts as my wireless router for my windoze laptop). Now, I have iTunes on my mac with my small but perfectly formed music collection on it and I'd like very much to stream said music to various rooms in the house, whilst also extending the range of my wireless network. Before investing in the Airport Express I could do with the following information, which I can't seem to locate either on here or via a wider google search. Firstly, how does the Airport Express work with an iMac (which has already got wireless connectivity and software installed). Also, how does one go about setting it up? Secondly, would the Express extend the range of the Netgear wireless router? (If not, is there anyway of achieving that with an iMac, Netgear and Express setup). Thirdly, there seems to be conflicting reports about multiple streams of music (if I purchase two Airport Expresses, one for lounge and one for dining room), can I play different tracks in each room at the same time, and/or have both rooms playing the same tracks at the same time? Finally, how does one go about setting up the Airport Express if I only have an iMac (are there any step by step guides about for example)? I look forward to your feedback and offer appreciation in advance. Homer J.
