If you are connecting using an Android device, go to the Google Play Store and search on the ‘xpressconnect’ by CloudPath Networks Inc (if you try to download it from the enrollment.net.unc.edu site your Android device will probably give you a message saying you can not install from an unknown source).  Once you install the xPressConnect app. then go back to the enrollment.net.unc.edu page to configure your device by clicking on the ‘Configure Device’ button (an example screenshot is shown below).
