Hum, intéressant : une loi allemande de fin 2015 entre en application en août 2016 et permet de se passer du routeur loué par le FAI.

Up until now, Internet service providers (ISPs) in Germany determined the router users had to use to connect to the Internet. The user had no say in this decision. This changes on August 1. A new law will allow users choose the device that gets installed in their homes.

"Compulsory Routers" are what we call the devices imposed on users, forbidding them from using any other appliance to access the Internet. Compulsory routers are often the subject of critical security flaws which users can't legally or technically fix themselves. They are also known to be incompatible with certain network devices and standards, like IPv6, or to support only a small number of important features.

However, the legal situation was ambiguous and ISPs defined the first router or modem after the wall socket as part of their network. They could thus bar users from controlling the technology installed within their own homes [...]

from August 1 onwards, clients of German internet providers are allowed by law to use any terminal device they choose. Regardless of whether it is a DSL or cable connection, the ISP will have to supply the information you need to connect an alternative router to use the Internet and telephone network.

Ho, donc les spécifications seront connues ?! Genre le FAI te cache pas le DHCP vendor-id ou le VLAN ID comme en France ?! :O Vaaaaache. Ça semble trop beau.
