Hello all, I need help. Seems my ethernet isn't working on my PB no more. I have tried plugging the same cable into other computers in the room and it definately works, but when I plug the cable into my PB, nothing happens. Attached are some screenshots. The ethernet doesn't even say "cable unplugged" or anything. And I've also attached an image of my system profile if it helps. Please help me! My PB is practically useless without it!
