"WI-FI is disables by hardware switch" after resume from sleep.

Everytime I resume from sleep, GNOME's NetworkManager claims that the wifi is "Disabled by a hardware switch".

Now, I do kinda have a hardware switch. It is located on my F12 key, but pressing it (either with or without the "fn" key) does nothing.
`xev` return XF86WLAN when pressing it, but I don't think anything binds to this key.

I have a suspicion that some esoteric driver accomplished that on windows.

Any ideas how to fix this?

I think fn+F12 is a software switch.

Have you tried to enable it with rfkill?

I have. rfkill fails to enable it, reports the device as "hard blocked"

No, Fn + F12 / Wifi key is a hardware switch (The modern laptop's special keys  are now F1 - F12, and whenever you want to press really F1 - F12 you need to press Fn + F1 - F12, for example, Fn + F1 --> F1, and wifi key must be pressed Fn + Wifi Key ( A key is wireless internet icon ) too).

Guy, Gilnaa, the following steps may be help you:

1) Shutdown your laptop.
2) Start your laptop.
3) Check if your wifi is ok, try to suspend your laptop
4) Press Fn + F12 once no more, and waiting in 5 - 10 seconds
5) Check again with your NetworkManager, turn off your wifi  and then recan wifi.

Note:  In my case, Dell Inpiron 15 AMD A6.

I think fn+F12 is a software switch.
