Question about computers on same router

[dwayne00]

I have my station up and streaming. I want to check out my station myself and listen to the music to see if everything sounds good. But im not able to listen to it. I think I remember reading that I couldn't listen to my station from another computer in the house if they both were using the same wireless router but the only way that I could listen to it in the same house as the computer with my station on is to have a certain kind of wireless router that will enable me to listen to it. Does anyone know what type of router I would need on order to do this?
