To perform a DSL speed test, visit SpeedTest.net or DSLReports.com. Both websites offer simple-to-use platforms that provide information such as idle latency or ping time along with download and upload speeds in terms of megabits per second.
SpeedTest.net determines your Internet speed by performing an assessment upon clicking the Start button. The interface provides ping time and upload and download speeds in addition to the server's IP address and location. The website also determines your Internet provider, which you can rate using a five-star system. A button for retesting is provided for those who want to verify the accuracy of the test.
DSLReports.com allows you to check speeds for various Internet connections such as DSL, cable and satellite. To perform a DSL test, select the Speed Test link at the top of the page, and click on the DSL tab within the platform. The speed test takes about 45 seconds to complete, but you are shown a chart of variations in both download and upload speeds. Additionally, the platform offers idle latency times of other cities so that you can compare your local speeds to speeds in other cities. A grade is also given that determines the rating of your speed test.
