I am completely new to this entire OS and looks like i need some help. I just installed Lubuntu 13.10 onto my old Dell. The system runs great but i can't connect to the internet at all. Ive searched for hours from previous post but nothing has helped.

When i run terminal i get the following message:

ifconfig -a

Link encap:Ethernet  HWaddr 00:11:11:0d:9e:45  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

~$ cat /etc/network/interfaces

auto lo
iface lo inet loopback

Also when i go into /etc/networkmanager/networkmanager.conf it had said "managed=false" but i figured out how to change it to "managed=true" still nothing... I thought i had some computer coding background but man was i wrong. Please help me with this! Im not even sure if the OS can recognize the ethernet port ( It was working fine when i had Windows on it prior to Ubuntu install, and is the port that came with the computer) and the internet is currently working with a ethernet wired PC in a different room.

It looks like it's finding the interface just fine and the interface is "up" but it's getting no IP address on it. Does the network you're connecting to provide DHCP? Is it possible something is blocking DHCP? Can you provide some more information about the network layout? As a troubleshooting step, does it work if you manually provide an IP and subnet in your Lubuntu? – thomasrutter Mar 28 '14 at 3:32

Although I shouldn't be speaking, Have you tried

  1. disconnecting the ethernet cord
  2. shutdown the comp
  3. plug the ethernet cord in
  4. boot the comp

(not a reboot)-- Simple yet this has worked for me on a couple machines when running the live dvd. (I don't know why)

Hope this helps, if not, I hope someone can help you.
