WiFi Problem with G850F

[Wise.Guy]

Hello my friends,

I have an G850F with stock ROM, Android 5.0.2, not rooted. When i want to open WiFi, it does nothing. No networks searching, no errors, nothing. Anyone knows what seems to be the problem? It may be a hardware problem? What can be done?
Thank you all in advance for your responses.

I've reinstalled stock Android 4.4.4, with Odin + Pit File, but nothing changed.
Here is a screenshot:

Seems like a hardware failure.
