Wifi interface cannot load firmware

hey guys,
after upgrading my kernel to 5.2.1, my wifi stopped working. this seems like an already known bug:
https://bugs.archlinux.org/task/63117

I followed the suggestion to downgrade the firmware to "20190618.acb56f2-1". now, I get the error:

no suitable firmware found!
minimum version required: iwlwifi-9260-th-b0-jf-b0-30
minimum version required: iwlwifi-9260-th-b0-jf-b0-46

but: when I execute

modinfo iwlwifi | grep th-b0-jf-b0-4 

it shows me

firmware:       iwlwifi-9260-th-b0-jf-b0-46.ucode

in the output...

any ideas?

Re: Wifi interface cannot load firmware

I just fixed it for myself. Go to the newest version of linux-firmware.

Then go to

/usr/lib/firmware

and run this command:

sudo mv iwlwifi-9260-th-b0-jf-b0-46.ucode iwlwifi-9260-th-b0-jf-b0-46.ucode.old

This makes the latest firmware unavailable to the kernel, and it will then fall back to version 43.

Edit: formatting
