tbt3-udv ethernet DOA

No lights on the switch port. Swapped cables to one I know is good, still no joy. 2017 15" MacBook Pro running Sierra. I’d appreciate any help.

Hello Russ,

Thanks for contacting Plugable support. Sorry to hear about this issue. I’d be happy to help.

Some generic troubleshooting for this kind of issues would be:

  1. I’d ensure you’re using our Thunderbolt 3 cable that we shipped with the dock, at least for testing purposes.

  2. If you haven’t already done so, fully unplug the dock from all devices, power, and Thunderbolt 3 cable to the host computer. Wait about 30-60 seconds, then reconnect the power cable first, Thunderbolt 3 host cable next, and USB devices last. Sometimes a reset in this order can resolve issues like this.

  3. You can try an SMC reset: https://support.apple.com/en-us/HT201295

  4. Can you go to the network preferences while the dock is connected to your Ethernet connection and take a screenshot? In case you’re not familiar:

  1. In addition, can you grab a system profile report and email it and the aforementioned screenshot to support@plugable.com for me to take a look at:

This will give us a better idea of what might be happening.

Thank you,
