Hello @bjedomzyek,
Thank you for posting on the Startech.com Community!
I am sorry to hear you are experiencing issues with 127B-USBC-MULTIPORT.
Can I please ask if you have installed the ethernet drivers for the adapter or if you are using drivers automatically installed by Windows? If you have not already done so, I would recommend reinstalling the latest drivers from our website here.
Can I also ask if any other functions on the adapter, such as the USB ports or HDMI, are affected as well or if only the ethernet connection is affected?
I look forward to hearing back from you!
