So today I came home and notice I can no longer connect to xbox live. I was not banned, my internet is working, and of course I power cycled everything. I am able to achieve an ip address both wired and wirelessly, but I can't get to the internet with the wired connection. I can connect to the network, but I can't hit my media center or xbox live. It mentions the dns not being able to resolve it. I manually entered known good dns servers. It is possible that this is a case of a bad network cable. The wireless adapter is able to make it out to xbox live. However, it disconnects after about 5 seconds. I put it in the DMZ to avoid the moderate nat issue. I know my router is functioning correctly, as I have many other devices, both wired and wireless. I also changed ports for the wire, so it isn't a bad port.
Is there a way to maybe reinstall the firmware? I tried the reset to factory settings, but that did nothing, and since I can get an IP, and get out with the wireless, and hit the router with the wire, I am confused. Does anyone have any suggestions, or do I need to send it in to get repaired? It should still be under warranty. I use it pretty much as my media center, so it would suck to have to be without it for a couple of weeks.
