Sorry to hear things got off to a bad start. The first few weeks are always the hardest. Like a lot of people have said, just find things and people on campus that you feel happy and comfortable with.
I completely understand how you feel about the crappy internet connection. MY first year at college, I went in expecting great things from IT. Then I found out that the "fast connection" barely beat my 56K at home, and almost none of the file sharing programs I used worked, due to some wierd networking stuff. Besdies that, the connection to our dorm frequently cut out. However, you just learn to adjust to it in any way you can, and things will start to look up.
I hope the next few days go better for you! Try to get a fresh perspective on things, you'll feel better.
