How fast is your connection with the internet? Check it out - with the cnlab UX Test!

With the cnlab UX Test, internet users can check the quality of their internet connections. cnlab analyzes the results of several thousand measurements daily for its licensees and for the public.

cnlab UX Test

The careful analysis of speed test measuring data enables us to make statements on the performance of internet service providers, terminal device types or network technologies.


Users of the cnlab UX Test apps can analyze their own results in the cnlab-evaluation platform and compare them to other options - neutrally and independently of their own ISP.


The cnlab UX Test apps are available free of charge. They measure download and upload speeds as well as response times from your own device (PC, notebook, tablet or smartphone) with reference systems on the internet. In this way, you not only check the offer of your Internet service provider, but also the performance of your local network (LAN, WiFi, powerline, switches) and your computer (e.g. influence of network card, virus scanner, VPN connections).
