If you're looking to monitor your network and Internet speed, track overall bandwidth usage, and get several other very useful utilities, you'd do well to download the free NetWorx. With easy-to-read graphs and in-depth reporting tools, it's a great way for anyone--regardless of technical expertise--to track Internet use.
Among the most useful graphs are a bar graph that shows your current Internet use in real-time, and one that shows your average incoming and outgoing transfer rate, as well as the total amount of data transferred. There are also techier tools such as an easy way to run traceroute, which shows you the path an individual data packet takes to cross the Internet. So whether you're a novice who wants to see your bandwidth, or a more technically sophisticated user who wants tools like traceroute, there's something in this freebie for you.
