im in a dorm. I have a router just because there is only one eithernet port in here and me and my roomate both need internet access. I noticed that when I was plugged into the eithernet jack directly, i could view the shared music in Itunes that people had who also lived here. through the router, I cannot. we dont have anything configured on it. how can I configure it to make it so I can view shared music in iTunes again?
