After the last Dell updates to my XPS 8930, my Killer E2400 Gigabit Ethernet controller was adversely affected. The error was something about cannot update the "Suite," and the update was aborted, but something happened to the card. I can get proper download speed (800-900 MB), but the card will only upload 1-2 MB.

Current driver information:
Driver Provider: Rivet Networks
Driver Date: 1/14/2020
Driver Version: 9.0.0.50

I have disabled the Ethernet controller and am using WiFi, but I really want the Ethernet controller to work (better than 1-2 MB upload). Any thoughts/assistance?
