Hello,

Does your Wi-Fi antenna have higher dBi which is also called high gain antenna? Anything higher than 7dBi might be doable and possibly you may get a great signal from your college Wi-Fi network. I'm sure that it's detachable or removable so that you may upgrade it to a higher dBi, please check this out.
