So my school's wifi doesn't support my TV or something, all I know is the wifi doesn't appear as a potential connection for the TV. (Even then, when I plugged the TV into the Ethernet cable, it still gave me an error message.) Well I figured out a loophole Saturday night.

I plug the Ethernet cable into my laptop. Then activate the hotspot on my laptop. Connect to the TV through the laptop's connection. Problem solved.

Loopholes are one of the best parts of life.
