3 Error caused by Huawei UMTS stick 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 Samsung LTE dongle GT-B3740 is not supported

Samsung's mobile broadband dongle GT-B3740 cannot be used with the FRITZ!Box's USB port because Samsung designed this LTE dongle for use with manufacturer-specific interfaces. This is not an error on the part of the FRITZ!Box, this is due to technical reasons on the part of the Samsung dongle.

Note:Some mobile network operators offer the LTE dongle GT-B3740 under their own name. The FRITZ!Box detects the LTE dongle GT-B3740 as a USB storage device.

5 D-Link mobile broadband dongles are not supported

The mobile broadband dongles DWM-221 and DWM-157 from D-Link cannot be used with the FRITZ!Box's USB port. If possible, we shall add support for these mobile broadband dongles in a future FRITZ!OS update.

Note:You can have the push service notify you by e-mail when new updates are available. In addition, you can configure the FRITZ!Box so that new updates are installed automatically. You can enable these options under "System > Push Service" or "System > Update > Auto Update" in the user interface.
