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.

Update 3

While your conclusion was bang on the mark, that "wWired" was an unintended typo. –  ShaggyInjun Oct 20 '12 at 15:32
    
does the indicator shows a connection? if this is the case, can you ping 8.8.8.8 (or any ip in general)? –  Stefan Oct 21 '12 at 4:39
    
I am able to ping my gateway ip (This is the ip my internet company displays when I login ). –  ShaggyInjun Oct 26 '12 at 11:21
