Those statistics are bad. One thing that can definitely be killing your download speed is in fact your upload speed. As it stands right now, your sync rate of 64kbps on the upstream will result in roughly 45-50kbps of bandwidth, which will ultimately result in ~5KB/s of upload after overhead is considered. Basically something a dial-up modem with compression can beat, and thus can be bottle necking your downstream due to a choking of ACKs. Basically right now you seem to be suffering from a noise problem on the line. What you should do first is isolate the wiring in your house as much as possible. Make sure everything is filtered, the phone line sounds clear if you have voice service, there is no corrosion on any part of the jacks in your home, and nothing is shorting out or is damaged. If you are sure that the problem is not inside, get a tech out to repair the line. If you can attempt to locate a NID for your home (which might be all the way out at the street, or in a small box hidden someplace in the basement), then all the better.
