(1) In the last 2 weeks I’ve noticed significant lag in connections to the Pluable port. It will randomly freeze the typing in a window, slow to process a click on a link. I have troubleshooted the computer itself with Best Buy Geek Squad, internet connection, Chrome processes, etc.
(2) My computer does not have a port for a direct land internet cord, so I purchased a USB to the ethernet cord and it worked, deducing that it is the Plugable port that is not recognizing it.
I attempted to reset it last week but has not improved.
I am sorry to hear that you are running into issues with your TBT3-UDZ, but I would be happy to help diagnose the issue.
Just to clarify, when you mention that you had attempted a “reset”, are you referring to resetting the dock or the laptops? If you hadn’t already tried, I’d like to try performing a power cycle of the dock:
Disconnect all USB peripherals and displays connected to the dock
Disconnect the docking station from host machine, then disconnect the power adapter from power
Leave unplugged for 1 minute for power to dissipate
Connect docking station initially into power only
Connect docking station to host machine, then connect USB peripherals and displays, then test for functionality
