Ethernet port seems not to be working..
Couple days ago my internet stop working. I use a ethernet cable to get as much internet speed as i can. I replaced the ethernet cable and still cant get internet unless i use wireless. I know my router works i tired a different Mac. I did a lot of looking around for info but no such luck. Can anyone help. I pay alot for high internet speed that i need for work and cant use it because of wireless.
First check under System Preferences:Net

I am facing a similar issue here with my mid-2009 13.3" Macbook Pro.
All of a sudden, the Ethernet port stopped being responsive. I checked the Ethernet card and everything seems to be fine. Also, the port itself looks clean from the outside. I wouldn't mind replacing it for a new one by myself, but the ifixit guides do not have a tutorial on that (maybe it's not replaceable?).
Please help! :-/
