Have you tried refreshing or restarting your computer. You can also do the same for your WiFi box. I’m assuming you are using a WiFi box you’ve gotten from school so just inform them of the problems your having and tell them everything you tried to fix it and they’ll send a new one. I had the same issue with mine
