                  select the downloads link in the main menu, and click on the Network
                  Stumbler link on the downloads page. Once the installer has been
                  downloaded, double-click on it and follow the instructions to install
                  NetStumbler.
                      With NetStumbler installed, double-click on the icon to start it up. If
