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

  1. Have your cable provider unlock your FRITZ!Box. Depending on the provider, you can either use an activation portal or call their customer support 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

  1. Open the FRITZ!Box user interface.
