Then you modified something even deeper in the system. Can you tell us where you made the changes that caused your network communications to fail?

Strange... could you open your Terminal application as mentioned before and paste here the output of these commands (some were already mentioned, but bear with me :) ):

status network-manager

network manager should be running...

cat /var/lib/NetworkManager/NetworkManager.state

everything enabled there


a network interface should be up

route -n

quick look on your routing table

cat /etc/network/interfaces 

only loopback should be present


dns is working... i know I've posted a lot of commands here, but the output hopefully will give the ppl in this thread a better insight on the problem...

1) network-manager start/running. process 2432
2) no such library or directory
3) ifconfig

4) route -n

5) cat /etc/network/interfaces
auto lo

6) nslookup
^[[B^[[B;; connection timed out; no servers could be reached

Ok, this commands might help (I'm assuming that the cable is connected, interface is called eth0 and that there is a dhcp server somewhere on your network):

sudo ifconfig eth0 up
sudo dhclient
