In my bedroom I have two computers. I have one DSL bellsouth modem. My DSL modem plugs directly into my Linksys cable/dsl 4-port wired router. Everything works fine. So my xbox 360 is in my living room. When I want to play xbox I have to unplug my dsl modem and walk it into the living room and connect it. (no big deal, i just have to unplug a few cables) Well, I can not connect to xbox live. The only way I can connect to xbox live is if I bring my Linksys modem out to my living room, and run my dsl modem into that, and then my xbox 360 into the router. Anyone know what the hell is going on? It's bad enough I have to move my dsl modem back and forth, but to have to bring my router and my modem back in forth is a pain in the butt. That means i have to unplug 4 ethernet cables and 2 power plugs and walk them back and forth. I'm trying to figure out why I can't get my xbox working with just the dsl modem? Like some ports are closed or something? When I try to connect using just my DSL modem to xbox, it says IP confirmed but DNS could not be found. Any suggestions would be greatly appreciated.
