FRITZ!Box 7340 Service - Knowledge Base
Since updating FRITZ!OS, SMB access cannot be used
Since updating FRITZ!OS, you can no longer use the Server Message Block protocol (SMB) to access USB storage devices connected to the FRITZ!Box. As a result, you cannot configure USB storage devices connected to the FRITZ!Box as network drives on computers in the FRITZ!Box home network and they are not available as local storage in the Windows Explorer or macOS Finder.
SMB support has been removed
With FRITZ!OS 6, the FRITZ!Box provides a variety of new functions including support for the new DSL technology, vectoring (ITU G.993.5 / G.Vector). In order to integrate the new functions and technologies, it was necessary to remove Samba (SMB) protocol support.
