An internet connection is required in order to use many of the functions of Wisconsin App (formally known as Mobile UW). This document explains why.
Most of the content available in Wisconsin App requires an active internet connection. This is to ensure that current data is being displayed, since the vast majority of data in the application is time-dependent.
Users of an iOS or Android device with a data plan should have little trouble with this requirement. However, users of the iPad (without a 3g data plan), iPod Touch, and Android devices without a cell connection may encounter trouble since these devices require an active Wi-Fi connection in order to access data via Wisconsin App.
Wisconsin App checks for a working internet connection on startup, but does not recheck if the app is open and the phone is locked. As such, this is most likely to be a problem when browsing Wisconsin App and then locking the device, traveling to another location, and trying to use the application without connecting to Wi-Fi in the new location.
Ensure that there is a working wireless connection when trying to use Wisconsin App. If you are trying to use Wisconsin App after changing locations, make sure that you've successfully connected to wireless in your new area.
