I've had my xbox 360 for years, connected to a wired ethernet connection. I recently went wireless for 2 months and have moved it back to where a wired connection is, but now that the xbox is plugged into a hard wire I only get "To use a wired internet connection, make sure an ethernet cable is connected to both your console and your router or modem."
I know this port works because if I connect my laptop on the same wire, on the same port with my wireless disabled, the laptop will pull a DHCP address and connect to the internet.
when the xbox is plugged into the wire, the router light is also dead as if there is nothing plugged in.
Is there a way to reset / debug the Ethernet port on the old (white) xbox 360?
