I upgrade inspiron 7537 windows form 8 to 8.1. Wireless deiver is installed but it always show airplane sign. when I try to disable airplane mode its button is disable its not working. I uninstall the driver and try other versions of drivers but after installing driver it shows airplane sign. When I use windows 8 wireless driver insted of windows 8.1 driver then I am able to connect to network with the help of its software windows show wireless signal sign instead of airplane sign but when I click on the singals sign to see network and connectivty it automatically goes back to airplane mode which have no click able button to turn it off.
