Firmware can be uploaded to the device in different ways, for example via LANconfig, WEBconfig or a terminal program. A number of different protocols are available here.
In most cases, uploading or updating the firmware does not change any of the settings in your device (exception: Upload with reset). Nevertheless, as a precaution you should create a complete backup of your configuration. You should also have a backup of the previous firmware version in case the update process fails and, for example, the device falls back to a minimum firmware that does not allow Internet access. If you no longer have the corresponding firmware file, look for it under www.lancom-systems.com.
If the newly installed firmware contains parameters that are not available in the current firmware of the device, the missing values are supplemented with the default settings.
