I use dial-up, and I don't have download problems unless I put some other sort of strain on my connection when I'm downloading (like using my web browser to look at other things while downloading). The only thing that will disrupt a download for me is when there is instability on the other side (like frequent resets or something). When I buy things for download, I only buy one at a time, and I start big downloads just before going to do something else.
