Im on a macbook (black, model 4,1), and it seems my ethernet doesn't work. When I plug in the cable, System Preferences > Network says:
This suggest that the ethernet card is at least partially aware that there is a cable connected, and that's why I'm not 100% sure it is a hardware issue. The yellow light is consistent; it doesn't switch between green/yellow/red. Without a cable Network (obviously) says:
The network is configured with DHCP. Info:
- I've tryed plugging in other mac's and it configured automagically; worked straight away
- Internet works fine when the same cable is connected to my Airport
- Ethernet card is Marvell Yukon Gigabit Adapter 88E8055 Singleport Copper SA
- Ethernet doesn't work in Ubuntu either
- I can't ping anything.
So, bottom line: is the ethernet card broken, or could this be a software / configuration issue?
