Broadcom 43142 ERROR @wl_cfg80211_scan : WLC_SCAN error(-22)

I randomly couldn't discover/ connect to my wifi AP.
Here are output of some commands:

        lspci -k

I have referenced this thread , and this post , but the issue still persists.
Could someone please help me figure out this issue to fix it.

Please paste details of the driver you are using (including version, how you installed it and what modules, if any, you have blacklisted), kernel version and output of `rfkill`.

I installed broadcom-wl-dkms, rmmod'd the other modules(they weren't installed), and modprobe'd wl, but it still won't work.
rkfill shows that there's no software/hardware block.

Thanks for searching nonetheless

I don't have a clue. I had pulled out the card for a few days, so used ethernet all that while. I may have upgraded the packages, which I guess may have changed some things.
When the card was re-inserted, `dmesg` was flooded with the error (in the title).

What does "randomly" mean and do you have tlp, laptop-mode-tools or powertop installed?

'randomly' was a tl;dr. The error occured after I re-inserted the same card, about after a 5 day gap.

Don't have any of those packages installed.
Could the issue be related to Network Manager? The wiki says they're mutually exclusive.

Issue is fixed.
Wireless radio was somehow toggled off in the BIOS.
Mods please mark this as solved
