need Xbox live connection help

[Vipershark]

okay go into network connections
if your xbox is plugged into the computer through the ethernet port then the computer should recognize it and it'll show up in network connections

now highlight both the xbox and your wireless connection (ctrl+click)
right click and there should be a new option to bridge the networks
click that and the computer should stop for a second as it works and a new option should show up called network bridge

it should work now and I don't think you need to do any configuration and stuff
