My ISP provides internet speed of 900/10.  Over Ethernet, speed tests show 900/1.  Connected over Wi-Fi, the speed tests at 375/10.  Would like to use the Ethernet connection.  All drivers from Dell Command Update are current.  Running Windows 10 Pro and all Microsoft updates are current.

Most recently from Dell (Sep 2023) there was an update for the Killer PCIe Ethernet Controller Driver.  When I remove the most recent update and restart the computer, a Microsoft driver is installed.  Everything works fine with 900/10 Ethernet speeds until I restart the computer a second time and the Killer E2600 driver gets reinstalled.  Speeds back to 900/1.

Guidance please.  If you need more information, just ask.
