i have time warner cable internet and my xbox live connection isnt working. My home wireless and ethernet work perfectly, but whenever i try to connect my Xbox to live, it says that i am connected to the internet, but that it cant connect to xbox live

Hello

We've tried these solutions a few times. Don't know why it isn't working. Xbox live gold isn't connecting to my internet. I have Internet connection. That's not the issue.

We've disconnected and reconnected the wireless connection at least five times but still Xbox can't connect? Any other clues please?
