If you're experiencing the Ethernet port is not working. Please refer one of the following things below:
1.) Make sure the cable connection setup is correctly. Rear USB-C port is for the USBC power adapter and the side USB-C port is connecting to computer.
2.) Make sure the ethernet cable is fully inserted when a click sound is heard
3.) If the Mac Filtering is enable in the router, user has to add the Mac address of the product in the Mar Filtering table. The Mac Filtering is normally under the Advanced Setting when log in to the router.
4.) If none of the port on the hub is working, then please replace the USB-C cable that connecting the hub to computer.
