Time Capsule 2 connections simultaneously

Hey guys, I just had a quick questions that i've spent all day trying to research, maybe i'm not hitting the right key words. I have a wired xbox 360 and using wireless on my computer. The internet is a university internet that I put in an ethernet address to configure to. So I connect the internet from wall to time capsule. Anyways, Whenever I use xbox live I cannot hit my wireless at all. My iPhone cannot connect to my wireless at anytime despite xbox live or not. So it seems the case that one connection is being strictly devoted to. I have my time capsule on bridge mode, but haven't had any luck switching to shared or anything without errors. Is bridge mode the right setting, does anyone know if both connections can run together? It has always worked just fine for me but recently my time capsule broke and I had to get it replaced and since then I can't get things going smooth again.

Sorry for the long post, I appreciate any help. Thanks again!

Thanks so much. The information about the bridge really sparked what I needed to do. Woke up this morning and shared IP address but I changed the ethernet ID from my computer to time capsule on university site and seems to have done the trick. Just couldn't remember the settings I used to use awhile back.
