Z460 WiFi Problem

[butterbescotch]

Hiya!
I am having a problem in enabling my WiFi connection, which is weird since few months ago I was enjoying it. I have tried to reinstall the wireless drivers from the installation disk which was provided by seller upon my purchase and I also tried the driver from the lenovo site. However, it said "No Matching Devices Found". 

Also, even if I try to enable wifi, like pressing "Fn+F5" or by moving the WiFi bar beneath I still get no response. Instead of the usual WiFi icon of the vertical bars, the icons on lower left yields the computer with an antenna icon , which is I guess the symbol for LAN connection. I have tried to connect an ethernet plug and yes It works but I need the wireless connection. 

Is there something I have missed? Please help me.

when you press fn+f5, do you see lenovo wireless management window?

Thanks for the reply Yigit.

No, whenever I press it, nothing happens. The theory is either the WiFi device or something like that got broken or there is a missing driver. But as I mentioned earlier, I have tried all the drivers and it all failed. The former theory is unlikely since I don't frequent on travels and my unit mostly sits on a table.

re-install power management and try again.
