Ethernet cable not working on thunderbolt 3 to mac air

Hi I have an cat 8 cable plugged in to my thunderbolt 3 box but for some reason it won’t pick the Internet up from this at all.

Amy help is much appreciated

Hello Mr. Harrie,

Thanks for contacting Plugable support! I’m sorry to hear about this display issue through your Plugable docking station, but I’d be happy to help!

Let’s perform a power cycle of the unit to reset its internal dock chipset. We’ve seen that this can often restore the dock to a working state when it is not quite working. To do this, please follow these steps:

  1. Disconnect all USB peripherals connected to the dock
  2. Disconnect the dock from the host machine, then disconnect the power adapter from the power
  3. Leave unplugged for 1 minute for the power to dissipate
  4. Connect the dock initially into power only
  5. Connect the dock to the host machine, then connect USB peripherals and test for functionality

If these steps help, great! If not, I’d like to request some logs from your system to investigate further. Could you please keep the Plugable dock connected to your system (with the non-working displays still attached), then navigate to our PlugDebug tool ( and follow the instructions there?

Please send the email with the subject “Ticket349371.”

Thanks for giving us a chance to help!
