Thank you for your reply. I appreciate the comeback, even if it means that the function is not available.
The Bartók and the computer trying to access it are both connected to a 5-port unmanaged switch of the simplest kind, a TP-Link unit model TL-SG105.
These two connect to the network by using one of the wired ports of an ASUS router model RT-AX88U, being configured as an access point. There’s no switch management capabilities in the configuration screens for this router. I think that it is fair to assume that it does not provide any management capabilities over the switched ethernet ports.
Is there anything else that could be interest, regarding my network configuration ?
