>   Ubuntu 19.10
>   Kernel 5.3.0-18-generic
>   Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi
> card.

>   and I end up opening a prompt to reboot.
>
>   The system is unusable. This happens even with the Live USB version.
>
>   The only solution I found was to download a different (newer) firmware.
>   Latest version from:
> https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi
>
>   This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz
>
>   I then manually copy the contained firmware to /lib/firmware, remove
>   all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode
>   that the kernel expects to load.
>
>   This completely resolves the issue.
