I am trying to set up ethernet on my MacBookPro16,3 using a Thunderbolt 3 to Ethernet adapter, but in System preferences the ethernet continuously shows as inactive. Perhaps my settings for ethernet are incorrect or perhaps this system just doesn't support ethernet and I am unaware. Whatever the case may be, can anybody let me know if they have ever experienced this and if you have found a way to work around this?

It is plugged in to my MBP. Unless you meant something other than "directly"?

Indirectly would imply a Dock, Hub, or Docking station.

You can Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379

To trouble shoot further you can:

—Try a SafeBoot https://support.apple.com/en-us/HT201262

Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and test. Reboot and test as caches get rebuilt.

In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a reboot will put it back to normal mode.

This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.

—Test issue in another user (or guest user) account  https://support.apple.com/en-us/HT204443

This will tell you if it a universal issue or isolated to your user/admin account.
