Hello - want to plug phone into my router using a usb c  to ethernet adapter and ethernet cable. When I do this the lights go on on the adapter. The phone registers than something is connected when I scroll down - says phone is charging other device with usb tap for more options. When it goes to usb settings all the other options are greyed out.  When I go to connections then more connectionsthe option for ethernet is greyed out. Do I need to download a driver for this? - I did see a download for usb on the US Samsung support page. Is it safe/allowed to download drivers from the US site? - am not in the US. Have tried customer services to no avail. Have seen someone with the same model of phone use a similar adapter to connect phone to router on Youtube. Any suggestions much appreciated. 

Thanks - Ka7

Most of the USB C adapters (USB hubs, Ethernet, display outputs) out there need no additional drivers for use with Android phones since Android 8.
Android is able to tell what hardware is connected to the phone's USB C port and set the options accordingly.
When you connect an USB C Ethernet, I reckon that's what the USB settings are supposed to set.
If yours matched the pictures I attached, there shouldn't be any further action to take.
