What should you do if your internet connection is slow?

First, we suggest testing your connection speed. As speed can never be guaranteed with a wireless connection like Wi-Fi, please connect your computer to the router using an Ethernet cable.

Go to and click on ‘BEGIN TEST’. Wait until all of the results are displayed (PING, DOWNLOAD SPEED, UPLOAD SPEED). 

  • YES: the results displayed are consistent with the speed of your internet subscription. The speed issue doesn’t seem to be caused by your line – please check your hardware and settings.
  • NO: the results displayed are not in line with the speed of your internet subscription. Restart your router: unplug your FRITZ!Box for a few seconds, then plug it back in.

Is the internet connection still slow?

  • YES: Please contact one of our advisors free of charge on 8002 8004 so that we can assess the problem in detail. 
  • NO: the problem is fixed.

Remember: during a 1 GB line speed test, the equipment being used may affect the results and may not reflect the actual line speed.
