Ok so the other day I bought a PS3 and I have been playing the new call of duty game. I want to play online but I am have a few difficulties. First I am using a cord to connect my PS3 to my modem. My modem only has one port so I have to unplug my computer cord for the internet and plug in the ps3. So when I go to the menu to run the test to complete my install on my ps3 it takes for ever and it keeps telling my it has timed out and cant find a IP adress. Whats going on, is it my modem, internet provider or what guys?
