Ethernet option missing from Network in system preferences
Good Day;
I have used the ethernet connection my iMac for a number of years, only switching to wifi occasionally. having used wifi recently when I attempted to switch back to ethernet, that option is missing from Network/(Location) automatic.
I restarted iMac
Shutdown and restarted iMac
reset NVRAM/PRAM
Reset Router
All of these were no change.
Under location, edited/locations, I added the name ethernet. This then gave me USBController , wifi, bluetooth pan, Ethernet and Thunder "something" Bridge. Activating Ethernet, the connection worked fine, although only when Location: is Set to Ethernet.
Why did ethernet disappear from the Automatic location? Can I get it back?
Is my only option re-installing Mojave? Will re-installing Mojave leave all my applications and data intact?
Thanks for any input.
