In this tutorial i will explain how you can change the IP address of your wired connection using Network Manager GUI interface. For the purposes of the article i have used Arch Linux 2009.02 with Gnome 2.24 and Network Manager 0.7. The GUI is gnome-network-manager (the binary is actually called nm-applet).

If you do not use Network Manager to administrate your network connections that this tutorial is not for you. Many distributions however have Network Manager pre-installed in with Gnome so if you are one of this users you can proceed. I assume that nm-applet is working normally so start by right clicking on the icon and select Edit Connections. A new window will open and by default should look like this.

Next I recommend is to click the Add button. If you use a desktop computer you can go ahead and edit the Default connection directly, but if you use laptop I would advice to leave the Auto connection as it is and just set a new one for the location where you are.

Once you have added new connection you can specify the Connection name and other features. What our goal is to set a fixed IP address for this connection. To do that you need to click on IPv4 Settings tab. On the drop down Method menu choose Manual

Next step is to click Add button and put the IP address of your choice. If you are not sure what IP to put please contact the local network administrator (ISP, IT department, etc) for assistance.
