Which is why we don't set it.

No, that isn't the right way to do it.

No.

It doesn't but thank you for trying.

I met this error too on f26. Googled and found so many people suffered from this problem and are still suffering.

[~]$ lspci
03:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 3e)

I tried copying /lib/firmware/iwlwifi-6000-4.ucode to /lib/firmware/iwlwifi-6000-6.ucode, the error disappeared, but wifi still not connected.

dmesg output attached

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale. The kernel moves very fast so bugs may get fixed as part of a kernel update. Due to this, we are doing a mass bug update across all of the Fedora 26 kernel bugs.
 
Fedora 26 has now been rebased to 4.15.4-200.fc26.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.
 
If you have moved on to Fedora 27, and are still experiencing this issue, please change the version to Fedora 27.
 
If you experience different issues, please open a new bug report for those.

dmesg F27 4.14 no bug

Hmm... maybe I have separate issue, or kernel config/fw changed between 4.14 and 4.15, but I discovered that on 4.14 I still get the same message in dmesg about load failing, and after that everything is fine and wi-fi works.

I think this is better tracked under the firmware package. Are you having wifi problems on 4.15 or is the only issue the error message?

Wi-fi is not working on 4.15 at all. On 4.14 it works but kernel logs still contains errors, so it is possible (yet not proven) that issues are unrelated.
In both cases, adding udev rule to prevent userspace firmware loading seems to have zero effect.

This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '26'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 26 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Fedora 26 changed to end-of-life (EOL) status on 2018-05-29. Fedora 26
is no longer maintained, which means that it will not receive any
further security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
