Note: For wireless users, 'wlan1' or a similar connection should be used in configuration. Generally, wired connections will follow the eth# schema.

3. Under ‘Wired’, highlight ‘Auto etho’ and click on ‘Edit’.

4. Inside 'Editing Auto etho' window, click on ‘IPv4 Settings’ tab.

5. Under ‘IPv4 Settings’, change the ‘Method’ to Automatic (DHCP) addresses only.

8. NOTE:

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
NOTE: The dhclient.conf location may vary depending on you linux distribution.

To locate the correct file you can use:
$ sudo find /etc -name dhclient.conf

$ gksudo gedit /etc/dhcp3/dhclient.conf
# add the following line to the document before the 'require subnet-mask' command
supersede domain-name-servers 208.67.222.222,208.67.220.220;
# 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.
