Update failed?

[Lunar_Wolf]

Xbox won't let me on live, it's connected, but it keeps saying update something so I click yes, but the update fails. I had a 360 before and it worked. This is my second xbox. I'm running the connection straight from the modem into the 360.

Don´t have any idea, so, the best thing to do is contact Microsoft
