MTNL Triband on Ubuntu LIVE CD. Here what i referred to make it work:- "right click on your desktop. you will see a menu entry "run terminal". click it. a terminal should pop up. now type: sudo gedit /etc/resolv.conf hit enter. now enter the superuser password (= by default the same password that you use to login, if you are the first user on the newly installed system) the editor should come up the the resolv.conf file. Now type valid DNS entries in this manner nameserver 188.8.131.52 nameserver 184.108.40.206 nameserver 192.168.1.1 once you have modified your file, save it and close the editor. Now the most important part.... somehow the dhcp client keeps modifying the resolv.conf in a set amount of time and that's why the net dosent work.... so you have to lock the file so that it cant be modified now, back at the terminal, type sudo chattr +i /etc/resolv.conf now open your browser or synaptic and test if everything works. if not, report back. ohh and btw if you do realise that you have to change the DNS entries sudo chattr -i /etc/resolv.conf This will unlock the file again" I did the config as above but it didnt work.....Plz help.
