Hello,
I'm regularly facing an issue where cold-booting a laptop while on battery
(not on AC, not on warm reboot) leaves it without wifi because the firmware
crashed. A simple 'modprobe -r iwlmvm && modprobe iwlmvm' "fixes" the issue.
The card is Intel Wi-Fi 6 AX 200. I'm pasting 'dmesg | grep iwlwifi' below.
Can I help in identifying the problem?
Thanks.
Alexander
