Hotspot information

Please turn off individual hotspots on campus. These hotspots diminish the bandwidth on campus and disrupt the entire network.

Another tip for a quick Internet connection on campus:
Turn off the Wireless of your device once you are seated and wait a minute. As soon as you enable the Wireless again, your device will connect to the next Access Point.
