When this helps

  • You use KPN in Netherlands.
  • Your connection is slower than expected, drops out or performs badly at certain times.

Check your KPN Box

These checks apply to KPN Box. Check the model before following its menus.

  1. Look at the Power light. Green means all is well; orange means internet, TV or phone isn’t working.

  2. Blinking red means the box is syncing and fetching an IP address; steady red means a fault, so restart it.

  3. For details, sign in and click Internetverbinding › Informatie (Internet connection › Information).

  4. Open the IPv6 tab for the IPv6 connection.

Separate the service from your home Wi-Fi

For the exact settings and supported equipment, see the KPN Box guide.

Do not factory-reset the equipment as a first step. A reset can erase service settings and interrupt phone service.

  1. Compare a wired connection to the router with Wi-Fi on the same device.

  2. Repeat the same test server during the slowdown and at a quieter time.

  3. Record download, upload, latency and whether another household device was using the connection.

How to complain to KPN

Use KPN’s official support to report the fault. Request a formal complaint reference if it remains unresolved.

Include the plan wording, dates, test conditions, previous references and the specific outcome you want. Ask for a written response.

Check the complaints procedure in your Netherlands service contract before escalating. Use the national regulator’s consumer guidance for your service.
