I cannot connect to my university's wi-fi. I was once able to connect and I have no idea why I cannot anymore.

Also, more strangely, my "Internet connections" menu always has "Free Public Wi-fi" and "hpsetup." These supposed wi-fi connections are always there, even when I am in entirely different cities or on the freeway. And there are single dots above and below signal strength.

Is there like some way to reset the wifi or something? Any assistance would be greatly appreciated
