I have a USB-C screen that offers hub functionnality (usb, audio, ethernet). While the screen is perfectly connected and works like it should for usb, audio, and of course video, the ethernet connection doesn't work anymore.
I know it's not the screen because:
- I have succesfully tested it on another MBP,
- I have actually two screens of the same model and tried both.
This used to work but stopped working all of a sudden. I reset the SMC, and tried to plug the screen on different USB-C ports.
It is worth mentioning that the MacBook detects the connection if I plug the Ethernet cable via the USB-C Ethernet adaptor…
What else should I try (appart from reinstalling macOs)?
