I'm trying to help a buddy of mine setup two airport expresses in his house so that he can have (the same) music streamed to two different rooms. Here's the setup: Computer - PowerMac G4 with this wireless N card added. Two Airport Expresses, both the current wireless N model The ONLY purpose of the wireless card is to communicate with the AEs--he does not connect wirelessly to the Internet, and instead is hard wired directly from the cable modem to the PowerMac. We can get one of the AEs working just fine. We connect to the AE from the wireless card utility (a 3rd party utility which came with the wireless card), and it then shows up as an output device in the bottom right of iTunes. Works perfect in one room--but you obviously can't connect to two wireless devices at the same time. So we're thinking that we need to daisy chain the AEs. I tried setting this up, but there seems to be a catch 22. I setup one AE has an access point called "Man Cave AP" and checked the box "Allow this network to be extended". I was able to successfully connect to "Man Cave AP" and streaming iTunes still worked perfectly. Now here's the conundrum. I need to connect to the other AE so that I can tell it to connect to "Man Cave AP". That's where things get fuzzy. How do I do that? I figured it might be easier to connect it directly to Ethernet to configure, but I never could get the "Man Cave AE" and the "Guest Room AE" to show up simultaneously in the Airport Utility. I feel like I'm missing something REALLY obvious here. Can someone who has daisy chained AEs before give a brief run-down of the process? If we do get them successfully daisy-chained, is it even possible to stream music to two different AEs simultaneously?
