I just moved into a new house that has speakers wired into the ceilings of all the rooms. There are 6 inputs in the basement and each room can choose which input it wants to listen to. I am hoping to connect 2 ( or maybe even more if possible) airport expresses up in the basement so that both myself and my roomate can simultaneously stream separate songs in different rooms through airtunes. I know I can set this up if both airport expresses are separate wifi networks, but i want both computers to remain connected to the internet (and my modem only has one ethernet connection) 1. Can I have both airport expresses on the SAME wifi network but have 2 computers streaming separate music to each? 2. If not would I be able to connect a ethernet router to the modem and then connect both airport expresses to the first router and make each a separate wifi network? Thanks in advance!
