I am looking to buying a Airport Express..... I have a 802.11g network at home running from a speedtouch wireless modem thing.......there is a windows PC connected to it. I have a macbook which i use to connect to the speedtouch modem too (this is what i use the most)..... I just want a bit of advice....... If i buy an airport express and just plug it in in my bedroom upstairs and then plug my speakers into the airport express, will this extend my network from my speedtouch modem in the living room and then let me stream music fom my macbook through my speakers??? Is it as easy as this? or am i missing a vital part of the chain?? Thanks.
