USB-C Triple Display Docking Station - Internet Speed

Internet is “slow” on my connection. Directly connected, laptop gets 350Mbps on speedtest. When using the hub’s ethernet port, laptop only gets 30Mbps.
I’m using a new macbook pro.

Hello Cam,

Thank you for contacting Plugable support! Sorry to hear about this issue. I’d be more than happy to assist you.

The first thing I would like to check is to make sure you are using the latest DisplayLink 4.0 Mac drivers:…

If you’ve not yet updated to this version then take a look at the instructions here to uninstall the old version first:…

If that doesn’t help we’ll want to look a little closer at the network connection settings through the dock. I’d also ensure you’ve disabled WiFi just in case the system is defaulting to that connection when using the dock instead of the Ethernet on the dock itself.

Please don’t hesitate to let us know of other questions.

Thanks again for contacting Plugable support and best wishes!
