3 Error caused by Huawei E1550
The FRITZ!Box does not obtain a DNS server from your mobile broadband dongle if you are using the mobile broadband dongle Huawei E1550. This means that it cannot resolve the names of internet addresses (for example www.avm.de) and access internet servers. This is caused by an error in the mobile broadband dongle's firmware.
- Consult your internet service provider or Huawei for a solution.
Note:According to our experience, the error does not occur when using the Huawei mobile broadband dongle E1550 with version 11.608.10.00.47 of the firmware.
4 Vodafone K5006-Z is not supported.
The mobile broadband dongle MF821 from ZTE marketed under the name K5006-Z by Vodafone cannot be used with the FRITZ!Box's USB port. This mobile broadband dongle only supports the proprietary QMI protocol (Qualcomm MSM Interface) and not the PPP protocol required by the FRITZ!Box.
