Re:

Try System->Administration->Networking It will ask you for your administration password, select your ethernet card (ie. eth0) and click on properties. You will get a dialog box that will ask you for your internet settings. Change your configuration from DHCP to static and enter your ip settings. Then send me an e-mail
