CM12.1 WLAN can not be activated

Hi! I flashed the newest nighly and recovery (cm-12.1-20151019-NIGHTLY-amami.zip) and i can not activate WLAN!
In settings the switch ist light grey and if i touch it, nothing started. I can not move the button!

Then i go back to Stock ROM [XperiaZ1c_D5503_14.2.A.1.114_GenericDE(1279-6978)] to check the function of the WLAN modul and ... WLAN could be activated an i could use it. Then i flashed back to CM12.1, but the same problem! Could it be that i am the only person with this problem? What could i do? What should i do?

It takes me hours and nerves, but i can not find a solution. Anyone an idea?

Gear 2 Wlan

Hello
I don't know in which category i should write this question. Sorry if it's wrong.
I have seen that the bluetooth chip of the gear 2 has also wlan. Is there a way to use this?
I didn't found anything.

Thanks.
