My Acer ES1-521 has had a problem for the past week. Wifi does not work because airplane mode is turned on and it can't turn off. It is running Windows 10. I've tried:
1. turning it off using control panel / network & internet / airplane mode / switch off. (The switch keeps moving back to the 'on' position)
2. Pressing "Fn" and "F3" (which has the antenna wifi symbol) simultaneously.
3. Looking for a manual wifi switch which is sometimes on laptops - but this laptop does not have one.
I'm out of ideas! Any help would be greatly appreciated.
