So I noticed that when I installed my Time Capsule it gave me the option of having it join my existing wireless network when using the Airport Utility app. So What I want to know is, is it possible to get my airport Express (old model) to do the same thing? Currently I use it purely for the purposes of streaming music but have to swith between wireless networks to do so which can be a pain. Strangely it does not appear in Airport Utility when I launch it, just the TC does. Any ideas?
