News: Leo Laporte recommended this test over others on 19th July, on his weekly live show The Tech Guy. Thanks Leo! Test your download, upload and latency from a mobile phone up to optical fiber, and everything between. For gigabit+ testing please review this page. We don't use insecure or annoying browser plugins, this test is HTML5.

This test requires your browser's full attention for accurate results. Run the test when your network is quiet, and don't switch to other applications or change browser tabs during the test. A few Windows security and privacy software packages can block the test or slow the browser.
