FRITZ!Box 3390 Service - Knowledge Base
Why is the latest FRITZ!OS not available for the international and the A/CH edition of the FRITZ!Box?
A new version of FRITZ!OS with new functions is available for the German edition of the FRITZ!Box. Since the range of functions for the international edition and the A/CH edition differs, developing a new version for these editions is a more complex procedure. For example, these editions can be used with DSL lines that comply with either the "Annex A" or the "Annex B" standard. Furthermore, the user interface and online help must be translated into several languages. However, we will make the new FRITZ!OS available for these editions as soon as possible.
