Hey everybody. I don't know how, but ever since I upgraded my Mini's CPU this afternoon, I haven't been able to connect to my network through ethernet. It's plugged in the exact same way as it was before - the Mini to the router, the router to the modem, with the same cables. I can get online with Airport, but not my ethernet. Attached are the Network pane where ethernet is grayed out, and my System Profiler - I don't really know what the stuff under Built-in Ethernet means. Any ideas?
