Internet Diagnostic Tools

Different from bandwidth testers, Internet Diagnostic Tools try to test the reliablity and operational status of your desktop computer and network connection. They use several different methods to do this. Also useful to test if your ISP is manipulating your traffic. Most of them are to be considered experimental.

Internet Service Providers Bandwidth Testers

Testing your internet speed between your home or business and your Internet Service Provider is the best way to go if you're planning on making an argument to your ISP about your slow internet connection.
While it's possible that some of the other more generic internet speed tests further down our list are technically more accurate, it'll be a hard case to make to your ISP that your internet service isn't as fast as it should be unless you can show the same with the bandwidth tests they provide.

MPS Consulting Text Based Speed Test

Most people feel the need to test how fast their broadband modem is at downloading or uploading. To answer this need, several speed testing sites have sprung up. The problem is, none of these tests measure the actual speed of your modem: what they measure is the bandwidth between your modem and the test site itself, subject to a maximum cut-off at the speed of the modem. The bandwidth between two points on the Internet is determined by the hop in the path which has the least available spare capacity, and if that limiting bandwidth is less than that of the modem, then that is the reading that the speed test will return. This figure might or might not be typical of speeds you could expect to see from other sites, or at other times, depending on where and when the bottleneck is.

If you are fortunate enough to choose a test site where the available free bandwidth on all hops is greater than the speed of your modem, then the test site will indeed measure the speed of your cable modem, which is then the limiting bottleneck.
