I investigated the internet a bit – the Motorola SB5120 seems to be a 5 of 5 start candidate for a cable modem.

Unfortunately it seems to be discontinued. Are there any recommendations for a cable modem?

The next think I have to buy is some kind of router / switch combo. I had a SMC Barricade, but I gave it to a friend.

So I can start with a new infrastructure – no legacy ;-)

What router / switch has the best integrated firewall.

I am primarily interested in plug and play / buy solution– of course with configuration, but I do not want to

configure a box with 2 network cards and install every service I need on top of that.
