Why my modem randomly reboots during the day?

Hey guys, is anyone experiencing something similar to me?
Throughout the day. the modem provided by Fizz will randomly reboot and interrupt the internet for a quick 15seconds, but that's really concerning for me. As we are remote for classes, all the exams are online and universities are really severe during exams. If you lose internet during the exam, it means that it is the end of your exam.
