Setting up the FRITZ!Box for use with another DSL modem

With an additional ADSL, SDSL, or VDSL modem, you can use the FRITZ!Box even if the FRITZ!Box does not support the DSL standard used by your internet connection.

Since the FRITZ!Box establishes and controls its own internet connection over the modem, all FRITZ!Box functions (such as internet telephony, firewall) 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 the FRITZ!Box with a DSL modem

  1. Insert one end of a network cable into the "LAN 1" 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 DSL modem.

2 Configuring the internet connection in the FRITZ!Box

  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click "Account Information" in the "Internet" menu.
  3. Check whether your internet service provider is displayed in the drop-down list in the "Internet Service Provider" section. If your provider is not displayed, select "more internet service providers" first.
  4. If your internet service provider is displayed:
    1. Select your internet service provider and enter the internet account information you received from your internet service provider in the corresponding fields.
    2. Click "Change connection settings".
    3. Enable the option "Via an external modem" in the "Internet connection" section. If the option is not displayed, enable the Advanced View first.
    • If your internet service provider is not displayed:
      1. Select "other internet service provider".
      2. Enable the option "Connection to an external modem or router" in the "Connect via" area.
      3. Enable the option "Establish own connection to the internet" in the section "Operating Mode".
      4. Enter the account information you received from your internet service provider in the relevant fields. If account information is not required, enable the option "No".
      5. If your internet service provider requires you to use a particular VLAN ID, click "Change Connection Settings", enable the option "Use VLAN for internet access", and enter the VLAN ID.
  5. Enter the speeds of your internet connection in the "Downstream" and "Upstream" fields.
  6. 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.
