How to make my internet faster at an apartment complex?

I live in an apartment complex where the majority of the tenets are college students. and my internet is VERY slow, I cant watch a youtube video without it having to buffer for a few minutes. I can only imagine how many other different people are downloading movies and music. To connect to the internet all i have to do is plug my Ethernet cable into the wall. beyond that I do not know what I could do to increase the internet speed if that is even possible.

I have talked to the management, but really… they aren’t much help. I guess i am sacrificing fast internet for an affordable place to live
