Sir, I am beginner to Linux.

I have been trying to get internet access via Ethernet in my Ubuntu 11.04 but have failed to do so.

Whenever I attach ethernet cable, it starts scrolling (signaling that it has detected the Ethernet cable). But doesn't end up connecting to internet.

apurv@Apurv:~$ lspci -knn | grep -i net -A2

Please add more details: What version of ubuntu you are using? The output of lspci? The configuration of network-manager? Anything else relevant. –  Braiam Jul 25 '13 at 4:28
    
My ubuntu version is 11.04. sir I am new to ubuntu. I have never used internet on unbuntu before. So please guide me how to get "output of lspi", "congiguration of network-manager". –  Apurv Jul 25 '13 at 10:26
    
@Apurv, open the Terminal, type lspci over there. Upon hitting enter you'll get a result, copy that result and using the edit option you have on the site, edit your question with the output. –  Projjol Jul 25 '13 at 11:14
    
Umm... 11.04 is out of commission, try upgrading to 12.04 or later so we know that is not a software problem. Use a live-cd(usb) to check it out. –  Braiam Jul 25 '13 at 13:06

make sure you have configured the router/pc with the right configurations also make sure your cable are not damaged, i had the same problem due a damaged LAN cable
