Alright, I received an x-box360 for Christmas, and bought 12 months of live. We can reach with a Ethernet Cable, but are also trying Wireless. When we try Wired, It says our gateway is invalid or DHCP does not create a lease with the 360... also When Wireless is tried it says it knows its wireless, but can't connect to my computer, Please help!

hey, do you maybe have a firewall on your router or computer blocking the 360 or anyother wireless connections?
