Information: My laptop is an ASUS ROG Strix G15 G513IC-HN004W, with the ethernet adapter it is the Realtek PCIe GbE Family controller, it has the drivers 1168.8.515.2022, it gives me an error when trying to see the flow that went through the fast ethernet port. I have tried to run it as administrator, update the drivers and it still doesn't work for me. It only works for me if I connect it through an external usbc to ethernet adapter, how could I solve it without having to use the external adapter?

The error: The capture session could not be initiated on capture device "\Device\NPF_{C549FC84-7A35-441B-82F6-4D42FC9E3EFB}" (Failed to set hradware filtres to promiscuos mode: Uno de los dispositivos conectados al sistema no funciona. (31)) Please turn off promiscuous mode for this device. Thanks in advance

This is Npcap issue #628. Please add the details about your adapter, the version of Windows you're using, and the version of Npcap you have installed to that issue.

If you turn off promiscuous mode (uncheck the check box in Wireshark, use the -p flag in TShark), that might help.
