FRITZ! Box 6690 Cable
Good day I bought the Fritzbox 6690 Cable. We have UPC Sunrise, socket with the 3 connections. In the package there is a coaxial cable with 2 screw connectors. However, I cannot connect this cable to the socket. I need an adapter, transition piece. Where can I get one? UPC of course does not offer anything, neither does FUST, MElectronics. Thanks for any information.
