What I want is for any machine to still be able to access the internet. and for any machine to still be able to access the Time Capsule. So I want all machines connected to the same network. So isn't it possible to make the Timecapsule available to all machines by joining the main network yet still be plugged into ethernet into my machine machine? my main computer is in the living room, internet connection is in the bedroom and airport express is plugged into the bulding provided ethernet jack. whenever I have the Time Capsule join the network created by the Airport Express it's no longer available wirelessly from any other computer. It can only been seen from the computer that's plugged into it's ethernet hub.
