I have running OS X version 10.9.5.
I have used this adapter for 3 years and it stopped responding a few days ago.
The lights are on when I plug it in but the connection is not working. This is the message in my system preferences:
“The cable for USB Gigabit Ethernet is connected, but your computer does not have an IP address.”
When I put in an IP address it still doesn’t work.
I also tried uninstalling and reinstalling the drivers but that didn’t work either.
