I closed the laptop lid and reopened it to find that my computer had shut off, and when I turned it back on, it couldn’t detect any wireless networks.

After connecting an ethernet cable, the output of lspci was the same, still with no network controller, but ip addr was this:

Normally when the wifi is working there’s a wlo1 entry in the output of ip addr. I’m not sure why that’s not there, or why the wifi connection I usually use is showing up twice with different IDs.
I normally have Proton VPN with a killswitch, which I always had to manually disconnect from whenever I started up the computer, because it would block my wifi from connecting. I turned it off, hoping that would solve the problem, but it didn’t help.
I also only have the Flatpak and RPM Free repos, so I can’t use inxi.
Finally, this isn’t the first time my wifi has gone out with no explanation. The last 2 times it came back on its own after some days.
Thanks for any advice you may have.
