Slow Wired Internet Speeds

I just purchased the Plugable USB 3.0 Dual 4K Display Docking Station and have a very slow internet speed when connected via Ethernet cable. I have Spectrum Internet with an ASUS ROG router. My internet speeds via wi-fi are usually 480 download and 25 upload. When connected to the docking station, my download is 90 and upload 15. I have updated Displaylink and changed QoS settings but still get slow speeds. Any suggestions?
