It's possible your system isn't set to dhcp. In the command line, try

sudo dhclient

And if your internet starts working after this, then you'll need to configure your /etc/network/interfaces. To do this,

sudo nano /etc/network/interfaces

and change "iface eth0 inet SOMETHING" to "inet eth0 inet dhcp". If this doesn't work, please post the outputs of

ifconfig

sudo dhclient

and the contents of

/etc/network/interfaces

Please also post the output from the following commands:

lspci
lsusb
ifconfig
iwconfig

Have you recently made any changes to your firewall configuration?

Please provide the output from the following command:

sudo iptables --list

Are both ends of your network cable properly plugged in? Do you have a light on your router for the network connection?

Either save them to a flash drive (what you do is type the command and then a > to the file, eg,

iwconfig > /home/tanner2007/iwconfig_log

will log the output of iwconfig to /home/tanner2007/iwconfig_log instead of onto the screen - this works with any command) and then copy them here. Or, you could type them out manually...

And yes, manually messing around with /etc/network/interfaces will screw with your network manager. The network manager is nothing more than a nice front-end to that file, so it will obviously get a rude shock when you play with it's baby, but setting it back to normal should fix it.

PS. To get the network manager back, ALT+F2+"network-manager" for Gnome (Ubuntu), and ALT+F2+"knetworkmanager" for KDE (Kubuntu).
