For a long time my Thunderbolt acted like a hub, I had my printer and dsl cable connected and it was like they were hard wired to my macbook pro when I would connect the Thunderbolt cable to it.
NOW, it no longer acts like a hub. I have to turn on the WiFi option and run the internet as well as printer via the Wifi.
I am running 10.11.3 on my McBook Pro 2013 model.
Anyone know what would case this?
