Setting up the FRITZ!Box for use with another fiber optic modem

You can also use the FRITZ!Box with an additional fiber optic modem (ONT, Optical Network Termination) when the FRITZ!Box cannot be operated directly on the fiber optic connection.

Since the FRITZ!Box establishes and controls its own internet connection over the fiber optic modem, all FRITZ!Box functions (such as firewall, telephony) are also available without restriction in this operating mode.

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

1 Connecting FRITZ!Box with the fiber optic modem

  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 "Log In".
  3. If the menu "Account Information" is not displayed automatically, click "Account Information" in the "Internet" menu.
  4. Select "other internet service provider" from the drop-down list.
  5. Enable the option "WAN" in the section "Internet connection via".
  6. If account information is required, enter the account information you received from your internet service provider in the corresponding fields.
    • If account information is not required, enable the option "No" in the "Account Information" section.

      Note:If you have an internet connection from Deutsche Telekom, enter the following in the "Username" field, without spaces in between: Your "Anschlusskennung" (line ID, 12 digits), the "Zugangsnummer" (access number, normally 12 digits), the "Mitbenutzernummer" (co-user number, e.g. 0001), and

  7. Click "Change connection settings".
  8. Enter the speeds of your internet connection in the "Downstream" and "Upstream" fields.
  9. If your internet service provider requires you to use a particular VLAN ID, enable the option "Use VLAN for internet access" and enter the VLAN ID.
  10. Click "Apply" to save the settings.

Now the FRITZ!Box uses the account information you entered to establish the internet connection. Then you can configure your telephone numbers in the FRITZ!Box and connect your wireless devices with the FRITZ!Box.
