Start the speed test by clicking on the big button in the center of the page. The
check will start by downloading a file and will measure your download speed. Once
the download has finished, the broadband speed test will try to upload a file and
will measure your upload speed. (More)
If you want to get accurate results then you should not use your internet connection
for any other applications once the speed checker is running.
The broadband speed is measured in Mb/s (megabits per second).
