Comment 56 for bug 10239

Thanks for your quick response Mat.
The default was the first I've tried.
I thought I had tried everything, but I overlooked post #23 about the FRITZ!Box that I have as well. The solution mentioned there works for me too !!

I don't understand the logic behind it, the FRITZ!Box already knows the MAC address (from the nic itself, I guess).
Upgrading the firmware did not change this behaviour, but it does now enable you to enter the hostname yourself.
