Setting up the FRITZ!Box for use with a fiber optic connection from 1&1

The FRITZ!Box is optimally prepared for use with 1&1 and gives you unlimited access to all features, including internet, telephony, and TV (1&1 HD TV).

Connect the FRITZ!Box to the fiber optic connection. The FRITZ!Box is then automatically configured by 1&1. You only have to enter your personal account information in the FRITZ!Box user interface if automatic configuration is not possible.

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

1 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.
  2. Insert the other end of the network cable into the LAN port on the fiber optic modem (ONT, Optical Network Termination).

2 Configuring the internet connection in the FRITZ!Box

  1. Open the FRITZ!Box user interface.
  2. Enter the FRITZ!Box password given on the type label of the FRITZ!Box and click on 'Log In'.

3 Setting up telephony in the FRITZ!Box
