FRITZ!Box 3370 – Service - Knowledge Base
Mobile network throughput displayed as "0 kBits/s"
The FRITZ!Box user interface displays a throughput of "0 kBits/s" in the "Mobile Communications" menu although the FRITZ!Box connects to the Internet using your mobile broadband dongle, and Internet access works properly.
Cannot access information
The mobile broadband dongle does not have an open interface for accessing the throughput. As a result, the FRITZ!Box cannot determine or display the throughput. This is not an error on the part of the FRITZ!Box.
