there are a few tools that can add a few tweaks to make your internet browsing faster, but they tend to only make a small difference.
The best things to do are to get an advert blocker, that will reduce the size of the page you are downloading. And make the page load faster.
For a more drastic solution,
http://www.onspeed.com/en/ is a very good utility, my friend on dial-up swears by it. It works by acting as a proxy server, so to speak, you request a page, and onspeed downloads it, compresses it and forwards it to you. He says that his internet is way faster now.
