Title summarizes the problem. I have Kubuntu 12.04 installed. Not sure where to start debugging. Could someone guide me through things I should look for ?

Update:
I see eth0 and lo listed when I run ifconfig, but I cannot ping google.com or surf to google.
Update 2: Contents of /etc/network/interfaces.
# This file describes the network interfaces available on your network
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet dhcp.
I am using a Ruckus 2211 Wireless router, but using a wired connection to connect to internet.
Don't know if this helps but, I have two laptops, one runs Ubuntu and the other, Kubuntu. I am using the Ubuntu laptop to write this question up. It's the kubuntu laptop that is causing the problem. Ubuntu laptop is a relatively older Dell E1405 while the kubuntu one is an ASUS U46E BAL7.
