Hey guys, I am a student in university with a macbook that until now appeared to be working fine. I got up for 10 minutes, at the time the connection to the internet was working fine, and now I am unable to connect. I can recognize wireless networks, however I cannot test the connectivity due to my not having the passwords for nearby house's wireless routers. The external ethernet connection is dead as a doorknob. I have tested two different ports with 2 differet ethernet cords, and nothing work. Simultaeneously my roommate is able to connect fine from both ports. I do not see any pins loose inside of the port on the side of my computer, and other than that I am at all loss as to what I should do. Being in University I would prefer to do everything in my power to avoid shipping it to apple because my warranty is up, and I neeeeeeed my computer. Thanks for all of the help!
