Network Manager over rides DNS in Ubuntu *FIX*

Since i installed ubuntu on my laptop i been facing this problem.. after some inactivity my dns get changed and i have to manually change it to make it work.

it changes the dns to


so i would have to change it again and again to make it work this really pisses me of..

how ever after googling around for a while i found a fix.

Maxcom dns servers are



sudo cp /etc/resolv.conf /etc/
sudo gedit /etc/dhcp3/dhclient.conf
# append the following line to the document
prepend domain-name-servers,;
# save and exit
$ sudo ifdown eth0 && sudo ifup eth0

Your network card will restart and the problem is gone 🙂
