Setting up the FRITZ!Box for use with a fiber optic connection from DNS:NET

The FRITZ!Box is optimally prepared for use with a fiber optic connection from DNS:NET. Simply connect it to the fiber optic modem from DNS:NET and enter your personal account information in the FRITZ!Box user interface.

The complete FRITZ!Box range of functions for internet, telephony, and television (DNS:NET IPTV) is then available to all of the devices in your home network without restriction.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

  1. Have your personal account information for internet access and the login information for telephony that you received from DNS:NET ready.

    Note:You will find your account information in the DNS:NET customer portal under 'Meine Dienste > Fiber > Zugangsdaten > Passwörter anzeigen'. If your account information is not displayed there, contact DNS:NET.

2 Connecting the FRITZ!Box

  1. Insert one end of a network cable into the 'WAN' port on the FRITZ!Box. Use the network cable supplied with the FRITZ!Box, for example.
