Airport express music and printer?

Hi all, merry x-mas, happy holidays. Now my question. I am having a problem with my airport express. I had it set up to stream music, wirelessly print and broadcast my wireless internet all using my airport express. I changed y internet to a wireless linksys router and want to use my airport express for printing and streaming music only. Now my ibook won't connect to the express. When i try to connect, it won't recognize the express, all it will find wirelessly is the linksys router. i cant get a signal off the express. Any ideas? I tried using the setup assistant and can't read my express station.

Is it possible to have the airport extreme card in an ibook connect to both a linksys router for internet, and an airport express for wireless prinitng and itunes streaming at the same time? If so how? I can't get my ibook to recognize the airport express. It connects to the linksys fine, but won't read a signal from the airport express.

You have to use the Airport Admin utility to access the Airport Express. You may want to run the Airport setup utility first.
