Try sudo vi /etc/network/interfaces, and sudo vi /etc/resolv.conf that should let you edit the files.

If that doesn't work, try sudo su enter your password, and try editing the files that way.

  • can i edit it using text file? – user205787 Oct 23 '13 at 18:09

    You can do sudo su, and then gedit /etc/network/interfaces – Mitch Oct 23 '13 at 18:14

If you are using the desktop edition, you could also right click on the Network-Manager icon at the top right. (It should look like a little computer, Wi-Fi symbol, or a set of up/down arrows) In the menu that pops up choose "edit connections". Then enter your information in a manner similar to Windows.

If you're using server, and have no graphical interface installed you might try
sudo nano /etc/network/interfaces and sudo nano /etc/resolve.conf

Control + O will write the changes and Ctrl + X will exit.

Hope this helps. Have a great day.
