How fast could you surf at home? And how fast are you currently surfing? Take the Internet Speedtest to check the speed of your Internet connection. Also find out how you can optimise your internet speed with our additional devices.
Test your current Internet speed
Test your internet speed on your computer with thecnlab desktop app.
Why don't the tests detect the maximum speed for my subscription?
There are no other programs open on your computer.
The computer is directly connected to the Internet-Box with a network cable.
Every time data is transferred, including when testing the Internet speed, additional information is sent for each data package. This itself impacts the transmission speed. The test will therefore never measure the maximum speed. This is the case for every Internet provider.
Why do the results vary when I repeat the speed test multiple times in a row?
The test results depend on the current load of your Internet. The test results may vary if you have just installed certain updates, for example, or if TV is being watched in different rooms at the same time.
