Setting up the FRITZ!Box for use with a fiber optic connection from Vodafone

The FRITZ!Box Fiber is optimally prepared for use with Vodafone. Have Vodafone activate the FRITZ!Box, connect the FRITZ!Box to the fiber optic connection, and enter your personal account information in the FRITZ!Box user interface.

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

Requirements / Restrictions

  • Deutsche Telekom must make the fiber optic connection available. Currently the FRITZ!Box cannot be used directly with connections from other cooperation partners.

    Note:Who provides the connection is stated in the confirmation of your order. With connections from other cooperation partners, you can configure the FRITZ!Box for "Internet connection via 'LAN 1'" and use it behind the fiber optic modem from Vodafone.
