Ubuntu 13.10 no internet

[Errol Sapir]

I had the same problem when I installed 13.10 from scratch. As I 
couldn't get to the Internet to install drivers, I tried manually 
setting up my network. Nothing worked until I uninstalled network 
manager (sudo apt-get remove network-manager-kde network-manager) and 
then used wrote the commands for the network into 
/etc/network/interfaces using sudo, of course.
In the previous versions of Linux when one manually set up a network one 
setup the dns server in /etc/resolv.conf. I don't know when the change 
came about but now one writes all the commands into 
/etc/network/interfaces.
My system has a static network setup and looks like this:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 10.0.0.128
netmask 255.0.0.0
gateway 10.0.0.1

dns-nameservers 192.168.52.100 192.168.55.100

You will have to put in your info instead of the numbers I have. If your 
system is DHCP the network setup is:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

I don't know what one writes for the dns servers for DHCP but would 
guess that it is:

dns-nameservers DHCP
(but I could be wrong).
