If you are already on campus, you will need internet access to connect to eduroam. You can run SecureW2 by connecting to the umd-guest wireless network from the list of detected wireless networks. You can also consider using your phone's cellular data to connect that device or set up a personal hotspot to connect on computers and tablets.
NOTE: If you complete this process while off campus, you will receive a message stating the network may not be in range. Disregard the notification and click Continue to complete the process.
