ud-ultcdl is slowing down my internet speed

I recently upgraded my internet speed and purchased all the right gear to handle 300mbps. the only thing I did not upgrade was the Plugable USB-C ud-ultcdl. I had my internet provider come diagnosis my connection and this hardware was why I was not getting the full amount of speed. I did the property settings to 1gps and there was a small increase but nothing close to the full speed.

has anyone ran into this issue or know why this is happening? I have an Arris SB8200 modem, connected to an ASUS AC3100 router, connected to the Plugable ud-ultcdl connected to my Dell XPS15 9560.
