First remember that you are sharing the campus Internet connection with the other 4000+ users of Wesleyan resources.  You can check the Internet Traffic Report and see if you happen to be accessing at a time when load happens to be high.  Most likely however it is not the Internet that is going slow but your computer.  We have seen student computers so loaded with spyware that when they were connected to the internet the spyware used up all the students bandwidth causing other pages to time out.
