Indeed, I have a three band router and it always switches to the best signal without a problem.

so far, so good

Best place to download??

I got the upgrade through Intel® Driver & Support Assistant.

Any tips on how to identify which drivers to dl?

It's automatic...just run the Intel Driver & Support Assistant.

It will show what Intel drivers need to be updated and allows you to pick and choose what you want to download and install.

Direct link = Intel Killer Performance Suite 3.0.1606

The 3.0.1606 version of Intel Killer Performance Suite package installs the Windows 10 WiFi, Ethernet drivers, and Killer Networking Software for the following Intel Killer products:

22.70.0.6 for Intel Killer 1550/AX1650/AX1675
1.0.2.14 for Intel Killer E3100
10.050.0511.2021 for Intel Killer E3000/E3100G/E2500v2/E2600
3.1021.729.3 for Killer Networking Software

Note: This Software Release version does not include new drivers for the Killer E2200/E2400/E2500/1525 Wireless/1535 Wireless/Killer 1435 Wireless/Killer AX500 Wireless.

There's also direct DELL links for R10, that's where I found it. It will not show up (yet) if you use the Alienware update program.

Thanks for the tips!

Hello, so i did this update, and now the application does not work at all, used revo uninstaller to completely remove the software, went back to the dell site and reinstalled all the drivers and application, now it does not work at all still. Is there an issue with the software after the latest updates from windows? 

Online research indicates that Killer was from a company purchased by Intel, now dropped.  Searching the Dell website returns: "This driver is not applicable for XPS 8930 with Windows 11."  So it appears that this device is deceased, Intel doesn't support it, Dell doesn't support it, so apparently this was a bad coice on their part.  How do I replace this with something that works?  Is there anything I can do?
