I installed Ubuntu 13.04 while Windows 7 dual booted. I have a Local wired cable connection which is working fine with windows 7, but in the case of Ubuntu it is not working. I try to connect using Network Connections and Ipv4 Settings, in Method option. I use Manual and put all the addresses which my Internet Service Provider has given to me, but whenever I am going to save the Save... button grayed out. I have collected some data regarding this issue. using,

lspci -nnk | grep -iEA3 "(network|wireless|ethernet)"

it shows,

and

sudo ifconfig

Can anyone suggest how I can fix this and connect to my wired connection?

It seems that you do not have an IPv4 address. To set this:

First, open the terminal, and then type the following:

sudo nano /etc/network/interfaces

This will open a file, type the following in the file:

auto eth0

iface eth0 inet static

    address 192.168.1.100

    netmask 255.255.255.0

    network 192.168.1.0

    broadcast 192.168.1.255

    gateway 192.168.1.1

(Enter your own IP addresses instead the above.) Or, if you do not want a static IP, just type the following lines in the file:

auto eth0

iface eth0 inet dhcp

Save the file (CTL+X, Y, enter) and restart the network service:

sudo service network-manager restart

Hope this helps.
