Export the current configuration file (e.g., config.bak or .cfg ). If the update resets settings, you’ll need this to restore network parameters, user accounts, and custom logic.

Advanced firmware versions enable you to lock the device to a specific LTE band (like Band 3 or Band 40) to stabilize speeds.

Updating the underlying operating code of your USB modem ensures the hardware interacts correctly with modern cellular towers.

While extensive QA testing has been performed, the following minor issue has been identified and is scheduled for a hotfix in v3.1.1: Ldw931 Firmware Update
