I am having the same problem am about to uninstall back to 7.Please help
I noticed strange thing after installing hp wifi button driver
on pressing wifi button after logging in wifi button is in like a confussion b/w wifi on/off and airplane mode
if you press wifi button on log on on password window it will turn on your wifi
buy if you wifi is off and you logged in and then press wifi button then confussion arises with wifi button it switch on to airplane mode instead of turning wifi on
soo
restart your PC
then on login screen password window press your wifi button it will turn on your wifi and then login
your wifi will your without any issue and your screen control to turn on or off your wifi
and again when you restart your window later you again have to use wifi button on login screen to turn it on until you restart or turn your notebook on next time
I my case I am conclusion that wifi driver has some problem if you press wifi button on login screen it wil turn on and turn off your wifi (only after fresh restart not work if you again lock or log off and do it . it wil then go to airplane mode)
after logging in if you have not turn on your wifi on login password window then wifi button will trigger airplane mode
so
fresh restart login password window wifi button will trigger wifi on/off switch
and
after loggin in wifi button will trigger airplane mode
soo until this problem get fix in driver
you have to do this if you have same problem like me
I discover it accidently.
