Hello, I am pretty good with computers but I am a dunce when it comes to networking. Here is my problem. My room mate has the cable modem in his room. He has that plugged into a router and cables stretch all around the house to everyones rooms. What I did since I have a powerbook was use my old existing wireless router and just plugged that in to the cable coming in my room so I can have wireless access around the general vicinity of my room. All is fine and well up to this point but here is where I am completely baffled. Everything works fine when I am running wirelessly except I can not access anyones itunes libraries. SOMETIMES I get one of my room mates libraries but none of the other room mates. If I plug my powerbook in to the cable that is coming directly from his router I now can access all the room mates libraries no problem. I tried messing around with the airport settings in system prefs and I connected to my wireless router and tried changing some settings in there to no avail. I know this has to be able to work and any help would be greatly appreciated! Thanks.
