Setting up the FRITZ!Box for use with a cable connection

You want to set up a FRITZ!Box Cable? ✔ Here you'll find the right step-by-step instructions for your connection.

The FRITZ!Box Cable is optimally prepared for use with a cable connection, regardless of whether you received it from your cable provider or purchased it in a store.

FRITZ!Boxes provided by cable providers are already unlocked for cable connections and are configured automatically.

If you purchased the FRITZ!Box in a store, you must ask your provider to unlock it and configure it once. If you are using your FRITZ!Box in Germany, use the guide that applies to your provider in Setting up the FRITZ!Box: Guides for different providers. If your internet service provider is not listed there, proceed as described in this guide.

1 Unlocking your FRITZ!Box

If you purchased your FRITZ!Box from a retailer, your cable provider must unlock it first:

Important:In Germany, you can only use the FRITZ!Box 6490 Cable with the article number 20002778 with all cable connections. Models with other AVM article numbers are not intended for use with all cable connections.

  1. Have your cable provider unlock your FRITZ!Box. Depending on the provider, you can either use an activation portal or call their customer service to activate it.
    • With some providers, the serial number and the FRITZ!Box's "CM MAC" address are required to unlock it. You can find both of these on the bottom of the device:

2 Connecting the FRITZ!Box to the cable connection

  1. Connect the FRITZ!Box to the cable connection. For detailed information, refer to the quick guide included with the FRITZ!Box and the manual.

    Note:If a cable technician performed the original installation, use the coaxial cable (without an extension) provided by the technician to connect the FRITZ!Box with the first multimedia socket, or the one used by the technician.

3 Configuring the internet connection in the FRITZ!Box

The following steps are only necessary if you purchased the FRITZ!Box in a store:

Note:If you obtained your FRITZ!Box from your cable provider, it is configured automatically by the provider.

  1. Open the FRITZ!Box user interface.
  2. Enter the FRITZ!Box password on the bottom of the device and click "Log In".
  3. If the menu "Set up Internet Connection" is not displayed automatically:
    1. Click "Internet" and then "Account Information".
    2. Enable the option "Internet connection via cable".
  4. Wait until the "Power / Cable" LED remains lit.

    Important:Depending on the signal strength and the way your connection is configured, this can take up to 10 minutes. During this time, the "Power / Cable" LED flashes and then remains lit as soon as the connection has been established. If the LED flashes continuously, the cable connection has not been activated yet or the service is disrupted. In this case, contact your cable provider.

  5. If your cable provider did not unlock the FRITZ!Box yet:
    1. Open a new window in your web browser and call up a web page of your choice, for example
      • Now you will be redirected to your cable provider's portal for unlocking your FRITZ!Box.
    2. Follow the instructions given in the activation portal and make note of the login information for your telephone numbers, if they are displayed during the unlocking procedure.
  6. Click "Apply" or "Next" in the FRITZ!Box user interface to save the settings. Restart the FRITZ!Box to complete the configuration of your internet connection.

4 Setting up telephony in the FRITZ!Box

The following steps are only necessary if you purchased the FRITZ!Box in a store and would like to use telephones with the FRITZ!Box:

Note:If you received your FRITZ!Box from your cable provider, telephone numbers are automatically configured in your FRITZ!Box when your internet connection is configured.
