Slow and Inconsistent Internet at night lately?

Lately my Internet has been wonky at night since last Tuesday. I'm using a college internet and I've noticed that its only slowing down at night but is quite fast during the day.

Even when there were a lot of people sharing the wifi in the past at night, my internet would still be fast. I don't know what's going on. I've looked at my school's forum in a post from last Thursday where students say they have slow internet and that they had the technicians come over and check. I'm not sure what's the status so far. I don't know if it's my laptop having problems either. It seems my phone and Ipad are having no issues when it comes to wifi. Only my laptop seems to have trouble maintaining a decent latency.

Do I need to do a system restore or is this just the school internet? I'm so confused and just frustrated.
