Description of problem:
Recently-released wifi firmware package iwl7260-firmware-1:188.8.131.52-99.fc30.noarch causes the wifi card to endlessly reset, rendering it dead to the user. Reverting to a previous version solves the issue, tested with iwl7260-firmware-1:184.108.40.206-94.fc30.noarch .
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install the affected version of the firmware package listed above.
2. Restart the driver, either by rebooting the system or doing "rmmod iwlmvm iwlwifi ; modprobe iwlwifi"
3. Wifi card is now non-functional. Note errors in dmesg.

Can confirm this bug. dnf undo transaction doesn't work either, as it tries to downgrade to 220.127.116.11-98 instead of 18.104.22.168-94. Manual downgrade to 22.214.171.124-94 fixes issue.
Thanks for the workaround advice. Took it.
Downgraded to iwl7260-firmware-126.96.36.199-94.fc30.noarch.rpm.
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, 188.8.131.52-101, can anyone confirm if the issue is fixed or not?
Confirmed that 101 fixes the issue. This can probably be closed.
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.
Confirmed. Working with 5.2.9-200.fc30.x86_64 and iwl7260-firmware 184.108.40.206-101.fc30
