Macbook Internet Connection Issue

[Floyd1234]

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!

Well, I've experienced somewhat of the same problem when both my cabled network and airport are both connected to the internet or a network. Then nothing works. Unplug one of the two and one should work.

If that is not the case.....

Check to see that you have DHCP selected for your network connection. Click the in the top left corner and select 'system preferences. Click on Network and then on the drop down menu that says 'show'. Click 'Built-in-Ethernet'. It shoud say use DHCP. If not, make it so. Unless, of course, the network requires you to manually enter an IP address, but I doubt that.

Also, make sure that your firewall is turned on. Standard it is not. Check this at System preferences - Sharing.

Let me know if it worked or not.

Later, Parsec.
