If your FREDL from March, 2022 (or later) has conflicts in an "Other devices" category as shown below, download and install the updated LAN driver available at https://digitalintelligence.com/files/NP7859PQ_LAN_Driver.zip

To initiate the driver install, you can double-click on the SetupInf.exe program that's extracted from the archive. This will launch a silent driver install for the two unknown devices.
