This effective, free tool measures your Internet speed and lets you compare it with other types of connections.
Bandwidth Meter and Diagnostics appears in your Tools menu. Selecting it introduces a small pop-up window that displays your IP address and domain name. There's a button for a download speed test and an upload speed test, along with a message field that displays the status of the tests. Each time we ran a test, we were amazed at how fast the program came up with results. A new tab in our browser appeared almost instantaneously with the results in a line graph. The line graph gave us a side-by-side comparison of our bandwidth with other types of Internet connections such as dial-up, ISDN, and cable modems. There's a button on the pop-up and on the results page for a helpful support forum if you have any questions.
This is a great tool for users of all levels looking to check up on their bandwidth connection.
