Hi Tmonkey: Thank you very much for joining the Intel® NUC communities.
You mentioned you updated the firmware of the NUC, the latest BIOS version is 0046, just to confirm, is that the BIOS version currently installed on the NUC?

And we can also re-install the chipset and management engine drivers as well:
Let me know the results of trying those steps.
Any further questions, please let me know.
