There isn't going to be much to fix your slow online speed Walmart Security, those accelerators work by dumbing down graphics, resampling and compressing them at the server, then piping the smaller version to you wich gives you the illusion of speed. However, as you well know, this won't help you play games online, nor will it actually speed your downloads up.
As for correcting the material above, none of it will help you if have a poor quality phone line. The impression that I get is that if your line doesn't normally run DSL you run the risk of having too much wire between you and the dial in center. Why do I say that? Because DSL runs 12,000 feet from a home office, and if you are that far away, you are spending alot of time sending sound through repeaters and junctions.
