WAN automatic DNS vs Quad9...

[OzarkEdge]

This is a mash-up trivia post...

I have a new PC with a Killer AX1650 mini-card. It came with Killer Control Center bandwidth management software that seemed to mess with DSLReports speedtests. So I ditched the control software... just give me the device drivers, thank you. I ran the Killer software uninstaller, restarted, and then updated the unknown device in Device Manager using the Killer Win10 x64 1650 inf.

The problem was... I could not initially download the Killer bits... Chrome and Edge just complained about not being able to reach the download links. So, I thought to revert the 86U router WAN to automatic DNS (Spectrum) to not use Quad9. And that fixed it. Quad9 was blocking the Killer downloads. Afterward, I reverted back to using Quad9 DNS and the download links again failed to reach the Killer downloads. I suppose anyone using Quad9 DNS could attempt some Killer driver downloads to confirm the same.

This is the first time I've noticed Quad9 blocking anything.

Yeah, that's whacked. Works on their unfiltered 9.9.9.10.

We determined this to be a false positive. It should now be working. Feel free to hit us up via our support form with any questions in the future.

Thanks for extending your support to this community, Quad9! Very cool!

Footnote: I did first report the presumed false positive to Killer Support (Rivet Networks) and suggested they might want to pursue the matter with Quad9.
