Setting up FRITZ!Box for use with a Telenet line

To use the FRITZ!Box with a Telenet line, simply connect it to the cable modem from Telenet and configure the internet connection in the FRITZ!Box. The complete FRITZ!Box range of functions for internet, television (Telenet TV), and smart home is then available to all of the devices in the home network without restriction.

Important:Currently, Telenet telephone numbers cannot be used with the FRITZ!Box. The FRITZ!Box uses the common protocol SIP for internet telephony, but Telenet uses the standard EuroPacketCable 1.5.

1 Connecting a cable modem

  1. Either connect the cable modem to the first multimedia socket or to the socket that the cable technician used for the original installation. Only use the coaxial cable (without an extension) provided by the cable technician to connect it.

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 on 'Log In'.
