You can register the modem via a web portal during the first connection. After a few days you get the activation code via snail mail. But third party cable modems are expensive in Germany. You can also use the provided modem in bridge mode and use a better router behind hit.

That works with KD? Fking unitymedia removed bridge mode from their firmware. :(

I recommend the bridge mode + a better router solution.
