I have an early 2008 iMac and the ethernet port seems to have suddenly died without provocation. In Network Settings, for Ethernet it says, Status: Cable Unplugged. (it's not). Things I've tried: My PC connects fine so I took that working cable and plugged it into the iMac... no luck. I bypassed our router and plugged the iMac directly into our cable modem... no luck. Recycled the power on our router, modem, iMac... no luck Different cables... no luck. I created a new network and manually added ethernet using manual settings The ethernet status always says "Cable Unplugged." In the mean time, I am able to connect successfully via WiFi, but I'm debating whether to just write this off as a dead ethernet port and use WiFi from here on out (vs. waste money at the Genius Bar). My wife and I are both web developers so slower connection is a concern.
