Latest Arch update breaks wifi can't find wlan0 or wlp1s0

After doing `pacman -Syu` and then rebooting the wifi doesn't work anymore.

Even after a fresh install of Arch, wifi also doesn't work.

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855

Start by recording your HW

lspci -k

and in case/assuming your wifi doesn't show up there either, please post an older journal that still has the wifi, eg.

sudo journalctl -b -5 | curl -F 'file=@-' 0x0.st

for 5 ("-5") boots ago.

Chip is there, most likely https://bbs.archlinux.org/viewtopic.php?id=308389 - try to downgrade the firmware or the package in https://bbs.archlinux.org/viewtopic.php … 5#p2262695
