hi guys i wonder if any of you can explain the set up procedure to get started?? i've got a)core x-box b)ethernet cable c)12month x-box live card...i got home today expecting an evening of on line fun,thinking i've got everything i needed but still no joy i've even spent an extra £50 on a linksys wireless-g game adaptor to no prevail

The ethernet lead tells me i need ip address??? and the linksys not reconised on the pc for setting up? so stumped. any thoughts would be grateful
