Wired connection won't work

[CommuneOfLoon]

I'm trying to connect to a new wired internet connection I got at my house. My desktop, running Ubuntu 12.04, won't connect via the ethernet, though when I had the computer at work it would. The connection is good, as I tried the ethernet in the laptop I'm writing this on and it worked. I tried adding
auto eth0 iface eth0 inet dhcpto the interfaces gedit doc and then restarting networking via the terminal (as per the directions here: http://askubuntu.com/questions/16148...g-ubuntu-12-04), but I get the following:

stop: Unknown instance
networking stop/waiting

Any assistance would be greatly appreciated. Thanks.

Hi, if you are just running your desktop as a stand alone, not a server
the /etc/network/interfaces file should just look like this in 12.04

auto lo
iface lo inet loopback

if you plug bback in your laptop to the ethernet cabe and do

cat /etc/network/interfaces

it also will not have the extra lines you added, I would suggest
removing those added lines.
please post

ifconfig

thanks

And also post the output of:

sudo lshw -C network

thanks.

I have removed the two lines I added to the gedit networking file; as well, the two lines you said should be there are, Hadaka.

Here is the output from the two commands (sorry about the lack of formatting):

If you use CODE tags there's no need to be sorry.

If you use CODE tags there's no need to be sorry.

Perhaps you could explain how to do that or post a link explaining it?

Any help with my issue?

[JJSkoli]

Can you please post the output of

cat /etc/network/interfaces

Thank you
