fn+PrtScr opens up Airplane mode instead of wify in dell insp.5567 windows 10

Inspiron5567 opens up airplane mode after I simultaneously press fn+PrtScr and don't get wify in my under warranty laptop.Earlier I used to have wify open up but of late what I get is Airplane mode ON and when I simultaneously press the fn+PrtScr again the Airplane mode shows off.What it ideally should be opening the wify ON or Off.I am using the cable right now from my set top box supplying internet at the present moment.
