It should not be required that the notebook have an Ethernet chip, no -- but it does require the installation of a driver to function: [URL]  
I have an LG Gram (Windows 11 Home) that does not have an onboard Ethernet port.  Hence, it does not have a LAN/GBE Enabled/Disabled option in the BIOS.  It also does not have Realtek Ethernet drivers or Docking Station drivers in the Device Manager, even though I scan for new hardware.  I am connecting to the docking station through the LG Gram's thunderbolt port.  USB on the Docking Station works fine (charging, keyboard, mouse, thumb drive, etc) when connected to the Docking Station. Is there a way to get the WD-19S Ethernet port to work with the LG, or does a Docking Station require the native Ethernet capability in order to use the WD-19S Ethernet port? Thanks, PC
