Same problem here with L13v4. PureOS 10, kernel 5.10.0-19-amd64.
The kill switch is ON (Wi-Fi works):

Any ideas?

Solution: install firmware-atheros from debian non-free.

Just noticed that I have the same problem. And how do you install firmware-atheros from debian non-free?
Is it safe to put in apt configuration a line from Debian? I am on Byzantium on L13v4.

It was reasonably easily googlable, but I don’t have the exact link I used. This is the line I ended up having in my /etc/apt/sources.list:

deb http://deb.debian.org/debian buster non-free

The least safe aspect about it is not that it is from Debian but that the binaries are closed-source. So, use them at your own risk. Who knows what they do. I would recommend to backup the system in case you want to revert cleanly.
