Cannot add Ethernet as a service
I wasn't getting internet access through my ethernet adapter, so I tried deleting the Ethernet service to try re-add it. However, once I deleted the service, I cannot add it back.
There is no Ethernet or USB 10/100/1000 LAN option in the interface list.
There is no USB 10/100/1000 LAN option in "Set Service Order".
I have tried restarting my Mac many times (to no avail).
I also tried adding a new location, however, there is still no ethernet option.
How can I add ethernet as a service?
