It is best to use the modem you got from your Internet provider (e.g. Connect Box or Giga Connect Box from UPC) with the original power supply, original LAN cable and original HFC cable.

Disable the WLAN on your modem.

Please note: Connect your computer to the Internet with a LAN cable after you have deactivated the WLAN.

Remove all LAN cables of external devices (e.g. Powerline, separate router, UPC TV Box etc.) from your modem.

Please note: If your modem is in bridge mode, set the router mode.

The safe mode ensures that the speed test is not disturbed by other programs (e.g. antivirus software).

Please note: If you have an Apple computer, you can skip this step.

Install the free cnlab Speedtest on your computer or laptop.

Please note: Please remember that you must be connected using a LAN cable to perform the test.

Please activate the following settings in the speed test: Go to Settings > Measurement Settings

After you have configured the settings correctly, go back to the start interface in the speed test. Then press "Start measurement" to start the speed test. If you are not satisfied with the result, we have tips for you below.

Please repeat all steps with another computer to check the result.

There are several factors that can affect your Internet speed. We have some tips for you on how you can easily optimise your Internet performance yourself.

The download speed refers to the connection speed that is required to «get» the data. This includes typical services such as streaming (video & audio), downloading documents and of course regular Internet browsing.

The upload speed, in contrast, is required to «send» data, e.g. when uploading videos to YouTube or when streaming your own content (e.g. podcasts or on Twitch). The download speed is generally faster than the upload speed.
