FRITZ!Box 6490 Cable 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.
1 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.
