These bugs seem to be related:

> Latest iwlwifi driver crash at startup

> dnf update 22nd July 2019 included WiFi Update; WiFi stopped working after update reboot

Comment 4 Ryan David Sheasby 2019-07-23 08:25:57 UTC
Can confirm this bug. dnf undo transaction doesn't work either, as it tries to downgrade to instead of Manual downgrade to fixes issue.

Comment 5 Khalsa Jings 2019-07-26 01:21:05 UTC
Thanks for the workaround advice. Took it.
Downgraded to iwl7260-firmware-
Added a line to /etc/dnf/dnf.conf: exclude=iwl7260-firmware*
WiFi confirmed working again.
Awaiting the iwlwifi bug fix.

@khalsa, thank you for the steps to downgrade the driver firware. It resolved the issue for me (using a Dell precision 5530 laptop). I executed

> sudo dnf downgrade iwl7260-firmware

It is very annoying that upgrading can result in loss of wifi (happened multiple times now). New laptops do not have a wired connection option by default (or you need to have something like an usb-c to rj45 adapter at hand). Searching for a solution on the internet is more difficult and sometimes the downgrade is also only possible if there is an internet connection...

A new release is out,, can anyone confirm if the issue is fixed or not?

Comment 8 Erinn Looney-Triggs 2019-08-22 04:08:43 UTC
Confirmed that 101 fixes the issue. This can probably be closed.

Comment 9 Jason Benaim 2019-08-22 05:22:17 UTC
Hi- the problem is fixed now, not because of an upgrade to this package, but because of a new kernel.

Old kernel + -94 = works
Old kernel + -99 = broken
Old kernel + -101 = broken
New kernel + -101 = works

... where 'new kernel' is 5.2.9-200.fc30.x86_64.

I'll mark the ticket as closed. Thanks to everyone who helped take a look!

Confirmed. Working as described by Jason.

Comment 11 Jop 2019-08-22 18:07:01 UTC
Confirmed. Working with 5.2.9-200.fc30.x86_64 and iwl7260-firmware
