Any question answered...

Is there a fn+f1-12 button on the keyboard instead of a true hardware switch? What does it say if you look at the properties of the wifi controller in device manager?

F12 looks like the wifi logo but when I click it, it activates flight mode.

In device manger, Network adapter seem to just be ethernet. Below that is "Other Devices" which contains "Network Controller" which is the thing with the "!" over it.
