Have you set your connection speed in Steam to the proper one? It should match the speed you actually have.
Also, if you have any other things in the house using the internet at the same time, you're bound to get a sloppy connection unless you have broadband/cable or something better.
Add me on Steam. My name is RJ_Fighter.
EDIT: Whoops, forgot my friends list was full. If you already tried, try again now.
