I already had hard time initially stetting this network. My friend tried the same with AE on my advice and finally gave up and returned AE to Apple store. I'm computer literate, but more on hardware than software side. I'm planning to change layout of the room and long Toslink might be an option (now it is across the room). On the other hand everything around changes to wireless (phones, internet etc).
802.11n USB network adapter
I use two years old MacMini limited to 802.11g with 801.11n capable Airport Express. I would like to use 802.11n for the reason of lower interference of cell phones etc. but not sure if adapters like this one http://us.startech.com/product/USB300WN2X2-USB-80211N-300-Mbps-Wireless-Network-Adapter-2T2R would work. How complicated this would be setup-wise in Snow Leopard? AE in my current setup is installed as "to join existing network" but my 2-wire wireless router is not 802.11n capable. Would you advise change or is it to much hassle (I have very few droputs).
