Hello, thanks for posting. Sorry to hear that the Ethernet port on the dock is not working as expected and we’ll be happy to help!
Thanks for the description of the behavior and the steps taken to troubleshoot already. Does power cycling the docking station help by resetting the dock’s internal components?
Disconnect all USB peripherals, Ethernet and the HDMI display connected to the dock
Disconnect docking station from your laptop if it is not already, then disconnect the power adapter from the back of the dock
Leave unplugged for 1 minute for power to dissipate
Connect docking station initially into power only
Connect docking station to your laptop, then connect USB peripherals, Ethernet and the HDMI display, then test for functionality
Hi Ken H, thanks for your reply and glad to hear that this is now working. There are no device specific drivers for our UD-CA1A docking station because it uses features offered by the system’s laptop’s port.
Our dock does use a Realtek Ethernet controller that you reference.
