Internet LAN Line-connection was reset

Internet LAN Line-connection was reset

I have 12.04 LTS running on my machine. Since I have had Ubuntu installed
I have been unable to connect to the internet with my lan line. Whenever
firefox is opened the message appears, "This connection was reset, The
connection to the server was reset while the page was loading." This
happens with any website I attempt to visit.
When I run the command ifconfig the following appears:
hatch@hatch-MXC6300:~$ ifconfig

Also the firewall has been disabled.
Any help is much appreciated, -Cat
