I am currently using two separate boards with integrated I218-V and I219-V network adapters, hard wired through CAT6 cables to a switch.
When the I219-V machine is in S4/S5 sleep the link LED on the adapter and switch turn off.
When the I218-V machine is in S4/S5 sleep the link LED on the adapter and switch remain on.
Both adapters are configured with WOL disabled in the UEFI and also windows. The I218-V also continues showing a link if ErP is enabled. For my setup it is important to be able to tell the machines status by the light on the switch which is located in a separate room.
Any suggestions on why the two adapters are behaving differently, and how to configure them to behave in the same way?
Thank you for the post. It is recommended to contact the board vendor which integrated the ethernet controller on the system.
