XBox Live connection for 360
I have my 360 connected to my Cox gateway router via ethernet cable and still can't connect. It workes fine yesterday when I was on wireless, but won't connect tonight. I thought going from wireless to wired would help, but it didn't. Live status on here

What is Xbox LIVE?

Xbox LIVE provides you with the most amazing entertainment experience through the Xbox 360 console. You can download and play games, get instant access to a large collection of games and music, and connect with your friends.

Wireless connection

You can connect your Xbox 360 console to Xbox LIVE without the need for any network cables. There is a wireless network in place that your Xbox 360 console can use.

Requirements
• An Xbox 360 Wireless Networking Adapter (only available with the original Xbox 360 console).
• A wireless access point, gateway or router that is compatible with Xbox LIVE.
• High Speed Internet connection, preferably DSL or cable.

Note: It is not advisable to use Satellite, 3G or 4G mobile connections due to the possibility of slow performance or lag.
