As many return to campus for the beginning of Fall Semester, we fully expect to experience some issues with campus Wi-Fi. Campus has made many improvements to our growing Aruba Wi-Fi infrastructure, but increased traffic may reveal additional avenues for improvement. And some people will need assistance with individual devices on Wi-Fi.
Beginning next Monday, August 22, campus is increasing drop-in and phone support for Wi-Fi, for the first few weeks of the semester. Anybody with Wi-Fi issues is encouraged to call or drop-in, for quickest Wi-Fi support. An Instructor Hotline is available, and Hotspots can be requested. Please see the following page for details:
It’s important to troubleshoot any issues on a case-by-case basis, so that service can be improved for everyone.
