Airplane Mode cannot be turned off

[Vivek]

My hp laptop has a rt3290 chipset which stopped working while I used ubuntu 15.10 although it works on Windows 10 which I dual boot. I bought a usb wifi with a rt2870 chipset, which worked out of the box with ubuntu 15.10 but has stopped working since I upgraded to 16.04. Also, the airplane mode in connection settings is fixed at on and cannot be turned off.
