I have an Inspiron 7537, I upgraded to Windows 10 several months ago and never had a problem until the other day when airplane mode turned on for no apparent reason.  I've tried using the radio-tower button (all other keys work), as well as using network settings but each time I click airplane mode off, it automatically switches back on.  I did a PC reset but that didn't work and I've uninstalled and reinstalled the wireless driver as well as run Dell's driver scan several times to make sure all proper drivers are present.  There is no physical switch on the laptop for airplane mode, and again, the radio-tower button has no effect.  I have Ubuntu installed as well, and when booting into that the wireless card still cannot be activated.  I'm completely lost on this and have tried all possible solutions I've found online.  Please help!
