Cannot establish a wired internet connection on my linux computer.
 

I just finished building a PC for myself and I installed Elementary OS as my Linux Operating system. However, my ethernet is not able to connect the computer. Under the Wired Icon standing for ethernet it just says "Requesting Addresses...", and then after a minute or so it just say "Disconnected".

I did some research and saw that some other people had similar issues. Although all the solutions that I saw required the device to still be able to access internet. These wouldn't work for me because my motherboard doesn't have a WiFi card so I can't connect to the internet at all. Also I think that I'm right in saying that because my computer has never connected to the internet before that it doesn't have an IP address.

As far as the ethernet cable goes, the lights surrounding the cable heads are turned on. I also plugged the ethernet into my roommates computer and it connected just fine in there. This leads me to believe that the problem is with the Linux distro that I chose to download.

Anyways I hope I described the problem clearly enough, I'd really appreciate the help. :)

Sounds like you have the machine configured to get an address from a DHCP server. What is the DHCP server that you are using? Is it configured?

You've given no information.

Is the network interface working?
What is the output of
What network manager do you have installed? Is it configured?

Does elementary use systemd?
Look at the journal
Give more info.
