Shit, just linux.

Use this community for anything related to linux for now, if it gets too huge maybe there will be some sort of meme/gaming/shitpost spinoff. Currently though… go nuts

Wireless wifi is not working after a chroot rescue on Arch Linux. (self.linux)

So basically I stupidly tried to update while my thinkpad had low battery and it powered off halfway through the update. The system wouldn't boot because it was complaining that vm-linuz/linux was not found so I performed a chroot-rescue and got it to boot again. I must have messed something up during the process because now the device wlan0 is not showing up in iwctl device list. How can I fix or diagnose this issue? (I am using btrfs if that helps). Has anyone had a similar situation and can lend a hand?

Should all the above fail the new kernel might have a bug In the driver for your wifi chip, revert to previous kernel.

Edit: you could also try to install another kernel release. (Zen, tkg, etc.)
