Keenetic Runner 4G (KN-2211) and Hero 4G+ (KN-2311) has the option to update the firmware of the ASR1803S built-in LTE mobile modem.

To update the firmware, download a zip archive from Download Center -> 'Internal Mobile Broadband Modem Firmware' section for Runner 4G or Hero 4G+, extract the .bin file from it and upload it to the router via the router's web interface.

NOTE: Important! Before upgrading, make sure that your router is running KeeneticOS version 3.9.2 or later.

Go to the 'General system settings' menu, and under 'System files', click on the lte-firmware file entry, then click on 'Replace file' and specify the path to the firmware file of the built-in modem (.bin file).
