Public bug reported:
I have a HP 15-r014TX model numbered laptop. I recently installed Ubuntu
20.04 in it alongside windows 8 (actually upgraded fro 18.04). It had a
hardware problem causing wifi to not connect but only scan nearby
network. So I attached a usb wifi adapter and everything was working
till yesterday. Now I have airplane mode turned on and saying it can
only be turned of by hardware switch by default that laptop has F12 as
the default button to toggle hardware airplane mode. I tried it and
popup showed that it has turned it on but it didn't help me to turn that
off again. Referring to many forums I tried popular solutions to fix the
problem but nothing worked for me. I also checked bios to whether there
is an option but found nothing. No I discovered that the problem is only
with Ubuntu and in windows every thing works fine.
