edit: as per /u/hearthreddit's advice, downgrading to linux-lts seems to be working. time will tell, but I've done a few reboots and it's been working fine. probably gonna wait a few kernel versions and then try going back again.

(Thinkpad T14, haven't had any issues since I got it half a year ago)

Most of the time when booting my computer right now I don't have my wlan interface listed. Sometimes it works, but it's rare and a reboot doesn't seem to do the trick.

I read that sudo modprobe wl should help, but it says modprobe: FATAL: Module wl not found in directory /lib/modules/5.15.3-arch1-1.

ip addr show has a pretty long output, but what it shows is: loopback interface, ethernet interface, wwan interface, docker interface and br-0917411b9fd7 which I think is also related to docker.

Any ideas? It seems to load the driver just fine, but the device simply isn't listed in ip addr show so I can't use it. sudo modprobe iwlwifi also does nothing since it's already loaded.
