I live in Australia and i'm trying use a wired connection from my speedstream modem to my Xbox 360 to be able to play online.When i try to connect it comes up with test failed, Cannot obtain ip Address, i used to have online before and used the same system, modem and xbox but quit and now it wont work. I have very recently obtained a new computer if the means anything to my problem. I have tried every possible solution and guides i could find but none have worked so far. Also i can connect to the internet on my Computer but not xbox live if that means anything to my problem.
Any help would be Great!?!
P.S i don't know much when it comes to technical computer networking.
