WD19TBS Docking Connectivity Issues

Not sure if this is the appropriate place to ask, but I currently use MS SQL Server Management Studio (v18.10) for work. Whenever I'm on WiFi, I have no issues connecting to SQL Server databases, but as soon as I plug in my Ethernet cable, I can't connect and I get timeout errors. I would just stay on WiFi, but I'm currently using a docking station (Dell WD19) and for some reason, this docking station is causing my WiFi speeds to drop from ~500 Mbps to less than 5 Mbps. I've updated to the latest firmware, so I'm not sure if it's a setting or what. Any insights are appreciated.
