After you run "Test Xbox LIVE connection" and click on "More info", what is the exact message shown on screen?
Alright, I get the IP resolution issue. This just happens suddenly one day, I turn on my Xbox and I can't connect to Xbox Live. So I go ahead and do the usual turn on/off router and modem and wait briefly before trying again. Still nothing so I give it a day of rest or so which has worked in the past. next day I still cannot get a connection. So I start testing the connection and it appears it cannot connect to the router.
What is strange is the Xbox is the only one having problems. There are two other computers wired through the router and yet both can connect just fine. After switching some of the ethernet wires to different ports, I discover that wherever I connect the Xbox's ethernet cable, the router gives me a blinking orange light for that particular wire port. So I create a static IP address and forward a few ports; still nothing. DHCP is already on and the Xbox is the only piece of hardware having any connectivity trouble, everything else on the router and modem works fine.
The exact error message is as follows: "Can't obtain IP Address from your router or modem. Turn your router or modem off and back on, then wait 30 seconds..."
I've tried port forwarding and all suggested steps. I would be grateful for any insight as to how to solve this problem.
