No connection ATALl to internet/live

Okay check the cable of the xbox make sure its not broken or KINKED could have a broken wire somewhere make sure the wire work try the wire on a computer to see if it gets an IP.
Check the connector too, make sure none of the wire are lossen up, if so then replace the connectors or buy a new wire. make sure its Cat 5 or Cat 5E. doesnt have to be cat 6. thats overkill.

if its wireless then check if your router has WEP or WAP enabled, then you have to get the Key to get into the router, and make sure the SSID of the router is correct.

Hope this helps

Good Luck
