FRITZ!Box 7490 – Service - Knowledge Base
Why is the latest FRITZ!OS not available for the international models?
A new FRITZ!OS with new functions is available for the German version of this FRITZ!Box model. Since the range of functions for the international models differs, developing a new version for them is a more complex procedure. For example, these models 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. We will make the new FRITZ!OS available for this model as soon as possible.
Note:Until a new FRITZ!OS for the international model of the FRITZ!Box 7490 is available, you can install the latest lab version.
