put
      Code:

auto eth0

above the line
      Code:

iface eth0 inet dhcp


you would need similar on the line of "iface wlan0..."
you can use "allow-hotplug eth0", to connect if/when ethernet wire is pluged in.

Thank you for your reply.
It was actually a fault of my router. I restarted it and everything is working ok.
Strange that my other computer could get on the internet without an issue.
Sorry Sad
