I can't configer net in linux

What's the name of the linux you have? I used to have a GRPS modem from sprint that I got to work but I got it working with Ubuntu/Debian. There are a lot of PPP programs out there for Linux. All of them that I know about are free. In most distributions, if you look up PPP in the place where you can download programs, it will have a free PPP program to download. If you have one of the major distros like Ubuntu or Fedora, there should be a program named symantic where you can automatically install software for your computer. If you don't know what I'm talking about, be sure to write me back and tell me what the name of your linux is and I will be able to walk you through.
