How the VDSL speed test works
Measure your VDSL speed with the new speed test and compare your result with the measurements of other users.
Please make sure that all other programs accessing the Internet have been deactivated and closed before starting the Speedtest.
Especially messengers, web radios and e-mail programs can affect the test and have a negative impact on the measurement result.
By the way: The test now supports fiber optic connections!
