XPS 8930, Killer E2400 no Internet after Windows 11 upgrade

Hello.

I recently upgraded my Dell XPS 8930 from Windows 10 to Windows 11. Since then, I have been unable to connect to the internet. From the Dell support site, I downloaded the latest version of the Killer E2400 driver for my machine, however it's for the E2500 version. I don't see one for the E2400. Regardless, I tried installing it and when I try to upgrade the driver, Windows says the current version is the correct version. I have version 9.0.0.50 with a date of 1/14/2020.

Reviewing other threads on here, I don't have any Killer services nor processes running. Nothing has changed in terms of cables, router, nor modem. Other devices in the household are working fine.

Any ideas what I can try next? At this point, do I simply buy a new ethernet card?

Thanks
