XPS 8930, Bios update did it to me again! So frustrating
XPS 8930
I just installed a bios update named: Dell XPS 8930 System BIOS -1.1.17 -6.29 MB Critical. I had been using wired ethernet with no problems. It took me almost 1 whole year to be able to re-install the adapter after it erased on me. I kept getting the message "no compatible hardware was detected". I suspected Dell Support Assist suggested updates had something to do with it yet, wasn't sure? This was until Dell through a Support Assist Software Updates run offered me an ethernet driver and surprisingly it re-installed? This happened in May 30th, 2021. Now with this recent Bios update installed last night, I am back to square one? The ethernet adapter is missing? I cannot begin to wrap my head around what could be causing this "no compatible hardware was detected. The adapter was installed/working just fine before this? Dell CC? Anyone? See Attachments for idea.

Two items to try.
1. Reinstall the Intel motherboard chipset device drivers. One of the things the drivers do is define (identify) all the devices on the motherboard and attached devices.
2. If the chipset drivers don't fix it, try a CMOS memory reset. Power off PC, disconnect the AC power cord, press the power button for 10 seconds to drain any residual power. Open the case and locate the 2032 coin cell battery on the motherboard. Remove the battery for at least 5 minutes. Reinstall battery, reconnect AC power cord, power on and see if the NIC is detected.

@MidnightOil - If what @fireberd suggested, doesn't help, try this:
Manually set a System Restore point in Win 10, to be safe. Then open Device Manager and on its toolbar click View>Show Hidden Devices. Now scroll through all Device Manager looking for any "Unknown" or grayed out items.
Right-click and Uninstall all "Unknown" and grayed items. Next, click Action>Scan for hardware changes and see if the Killer Ethernet E2400 reappears and works. Assuming Killer is listed again, reboot and confirm that it's still listed in Device Manager and works.
BTW: I don't think you actually want to install the 17-May 2021 Killer Ethernet driver v2.4.1549, A27 that's being offered. I installed that update on my XPS 8930, but it's appears to be OLDER than the one that was already installed.
The May 2021 "update" installs Killer driver v9.0.0.42, as listed in Device Manager. I already had v9.0.0.50 running, and I had v9.0.0.49 before v9.0.0.50.
No clue why Dell suddenly offered a version that installs what appears to be an older driver. And v.50 works fine with Killer E2400 Ethernet in my XPS 8930, so I uninstalled Killer Ethernet in Device Manager (setting a System Restore, first) and reverted to the previous driver and back to running v.50 again.

What I want to understand is why does it not allow to install Killer Ethernet driver? Why is it generating message: "no compatible hardware was detected"? When installing Killer Ethernet do you need to have some suite installed or something. Perhaps it's this?

Did you reset BIOS as @fireberd said? Unless BIOS detects the NIC, you won't be able to install the Killer driver. So resetting BIOS is the first thing you need to do because that forces BIOS to look at all hardware that's installed. BTW: if the motherboard battery is old, you probably should install a fresh one, CR2032 coin cell, ~$2, instead of just reinstalling the old one. If nothing else, you'll rule the battery out.
I guess it's possible the Killer NIC failed, but you won't know this unless/until you reset BIOS...

If you tried the CMOS (BIOS) reset by my original instructions, retry leaving the battery out for at least 30 minutes or more. There have been some problems fixed by leaving the battery out for extended periods.

Glad you got it working.
But as I said above, don't install the "new" Killer driver v2.4.1549, A27. Install one of the two previous drivers because A27 installs a driver that's older than either of those.
You want to have Killer Ethernet driver 9.0.0.50 or 9.0.0.49, not 9.0.0.42 that v2.4.1549, A27 will install.
