Switching from wireless to wired

Just got Road Runner Turbo, but my speed is still awful. I'm running though a wireless G and would like to plug directly into the computer and test it again.
I unplugged from the router and plugged into the computer but got no internet. I set up (or thought I set up) a new connection and got nothing.
 
use the Device Mgr to verify there are no Red or Yellow Flags on the Network Devices.

Disable the WiFi device will make it easier to use the Network Wizard
CP->Network Connection Wizard
