Cannot connect to ethernet with wired connection

[SUPERFITTER]

I"m running Ubuntu 12.04 and I cannot connect to the internet with a wired connection.I ran the following to see what the problam might be and ran out of ideas.

dennis@dennis:~$ sudo lshw -C network

I downloaded and transferred these to my desktop:

http://packages.ubuntu.com/precise/build-essential

http://packages.ubuntu.com/search?ke...se&section=all

I don't no what to do now.

Thank You for any help.

Is there a driver or a program that I have to run or download?

Yes, you can install what's missing:

Package g++ is not installed.
Package dpkg-dev is not installed.
Package linux-headers-3.2.0-38-generic is not installed.

There is some possibility that these packages, too, have missing dependencies that need to be installed. In a few hours or days, I'm sure you'd get it. You could, alternatively install 12.10 and download and install linux-image-3.5.0-25 where your device is supported by default.

Hi,

this LAN driver is packed in the 3.4-backports-modules. Downloads for this kernel:

http://security.ubuntu.com/ubuntu/po...9.14_amd64.deb

http://security.ubuntu.com/ubuntu/po...9.46_amd64.deb

http://security.ubuntu.com/ubuntu/po...-29.46_all.deb

After the installation load the driver and install the missing packages:

sudo modprobe alx
sudo apt-get install --reinstall linux-headers-generic build-essential dkms linux-backports-modules-cw-3.4-precise-generic

and update the system.

Thank you chili555 and praseodym
No luck yet on this connection. Is there an advantage if I install version 12.10, will this cure my problem or is there a fix for this version 12.04?

There are no nameservers in your /etc/resolv.conf. On-the-fly:
