    I've had some very strange behaviour when using the Thunderbolt Ethernet adapter on my MacBook Pro Retina.

    When I plug in the cable that goes to the back of a Thompson Speedtouch ADSL router, I get assigned an IP address, DNS, default gateway. All is fine, I can browse the local network and can get to the router configuration page.

    However when I want to get to the Internet I can't get passed the router.

    However again, when I plug in my usb 3 to Ethernet adapter, use the same cable, all is absolutely fine.

    Has anyone got any idea what is going on with the thunderbolt - Ethernet connection?

    Sorry I don't have an answer, I can only say that I also have the thunderbolt Ethernet and it gives me problems occasionally as well. I just got a monitor that uses thunderbolt and plugging the Ethernet adaptor into the monitor makes the screen cut out and I have to reset the Mini to get the screen to come back on. It has given me network issues in the past as well.

    Good price point, but I have not had confidence in it.

    I know this doesn't specifically answer your question, but...

    ...my advice is to "use the connector that works".

    I guess the thunderbolt connectors will have to go back then.
