FRITZ!Box 6490 Cable Service

Integrating an additional FRITZ!Box into the home network via network cable

You can use a network cable to connect an additional FRITZ!Box to your FRITZ!Box Cable to easily and efficiently increase the wireless range of your home network.

Internet and telephony services configured in the FRITZ!Box Cable (router) are then available to the second FRITZ!Box (IP client) and the devices connected to that FRITZ!Box, such as computers and telephones.

Requirements / Restrictions

Note:The configuration procedure and notes on functions given in this guide refer to FRITZ!OS 7 or later; they may differ or not be available with older FRITZ!OS versions. You can find the version of FRITZ!OS on the "Overview" page of the FRITZ!Box user interface.

1 Setting up the router

In the factory settings, the FRITZ!Box automatically assigns the correct IP settings to all devices via DHCP. If you disabled the FRITZ!Box's DHCP server, reenable it:

  1. Click "Home Network" in the FRITZ!Box user interface.
  2. Click "Network" in the "Home Network" menu.
  3. Click on the "Network Settings" tab.
  4. Click the "IPv4 Addresses" button. If the button is not displayed, enable the Advanced View first.
  5. Enable the DHCP server and define the range from which the FRITZ!Box assigns IP addresses.

    Note:The FRITZ!Box has the IP address (subnet mask and assigns IP addresses from xxx.20 to xxx.200 in the factory settings.

  6. Click "OK" to save the settings.

2 Setting up the IP client


  1. Either use a network cable or wireless LAN to connect a computer to the FRITZ!Box (IP client). If the computer is already connected to the FRITZ!Box (router), clear this connection.

Configuring the operating mode

  1. Click "Internet" in the user interface of the FRITZ!Box (IP client).
  2. Click "Account Information" in the "Internet" menu.
  3. Select "More internet service providers" from the drop-down list "Internet service provider".
  4. Select "Other internet service provider" from the second drop-down list in the "Internet service provider" section.
  5. Enable the option "Connection to an external modem or router" in the "Connection" area.
  6. Enable the option "Share existing internet connection in the network" in the "Operating Mode" section.
  7. Enter the speeds of your internet connection in the "Downstream" (receive direction) and "Upstream" (send direction) fields.

    Enter 32000 for a downstream of 32 Mbit/s; enter 2000 for an upstream of 2 Mbit/s.

  8. Click "Apply" to save the settings.

The FRITZ!Box is now configured for operation as an IP client.

Note:When the FRITZ!Box is configured as an IP client, it can no longer be reached at; instead, you must use the Mesh overview of the FRITZ!Box (router) or use the IP address that is assigned to it.

3 Connecting the IP client

  1. Use a network cable to connect the "WAN" or "LAN 1" port on the FRITZ!Box (IP client) either directly or by means of a hub or switch to a LAN port on the FRITZ!Box (router).

4 Setting up Mesh

If FRITZ!OS 7 or later is already installed on the IP client, you can configure it so that it adopts all of the wireless settings from the FRITZ!Box (router) and the wireless networks of both FRITZ!Boxes are then centrally controlled and optimized by the FRITZ!Box (router):

5 Setting up telephony

If you also want to use the telephone numbers configured in the FRITZ!Box (router) with telephones connected to the IP client:

  1. Configure the FRITZ!Box for making telephone calls over the other FRITZ!Box. If FRITZ!OS 7 is installed on the IP client, configure telephony in the Mesh instead.
