LAN on my Ubuntu 12.10 has stopped working suddenly. I tried the following command

gksu gedit /etc/network/interfaces

added the below lines

auto eth0

iface eth0 inet dhcp

and then restarted the network manager but this did not help. Also 'sudo rfkill list all' gives

soft-blocked: no

hard-blocked: no

And sudo rfkill list wlan does not give anything.

I cannot figure out the problem. Please help!
