Hi guys. My fn key is not working sometimes. Fn+f9 is the key to switch-on or off my wifi.once I shutdown or restart my laptop, wifi disabled,so literally Every time I'm struggling to switch-on wifi . I have already checked in services.msc file.. it already set to automatic. I tried with virtual keyboard(fn+f9). but its not working. Is there any software or settings to permanantly switch on my WIfi?
