To avoid having your settings get revoked after reboots, or after periods of inactivity you may need to make the following changes via the command line:
$ sudo cp /etc/resolv.conf /etc/resolv.conf.auto
$ gksudo gedit /etc/dhcp3/dhclient.conf
# append the following line to the document
prepend domain-name-servers 126.96.36.199,188.8.131.52;
# save and exit
$ sudo ifdown eth0 && sudo ifup eth0
You may be required to change eth0 to your own network device's name if it uses a non-standard name.
