Check your mail from today for more details on helping students with wireless problems.
Here's the short version.
1. Ask if they have changed their password or been notified to do so recently. This is the reason for the vast majority of wireless problems.
2. Have them reset their password on a wired network computer.
3. Follow directions to reset on their devices found on this page: http://technology.gsu.edu/technology-services/it-services/wireless-networks/
4. If all else fails, send to CAT-Lab (if open) or call technology help line. 404-413-4357
