Slow shared apartment internet?

I live in a college apartement and we have to share the internet since it the cable internet and phone come in one package. The internet for the past (3-4)couple of days has been very slow. I can download uploads pages or files. I'll be surpised if this page request goes through. When I go to the network center it says my broadband detection is good, when it is not all . I have rediculous times like a .txt file should only take 1 min or less to downlaod and it says three hours.
