How to proceed
- Visit the CNLAB test page to run several speed tests and note down the download and upload data rates.
- The DSL overview page provides the upload and download speeds for your DSL subscription. Compare these figures with the average values measured on the test page. The average values should be between the specified minimum and maximum values.
- Speeds may vary depending on various factors (e.g. distance between the telephone connection and the telephone exchange, WLAN functionality, computer overload, etc.). Additional information can be found in the FAQ on the “CNLAB” test page.
Switching to a slower Internet connection immediately may be subject to charges if your minimum contract period has not yet expired. You will be provided with relevant information during the order process.
