No, no, it's my fault, I had kept this old following files (I know it nothing on Linux), I removed them with Synaptic, (at this moment there the kernel 4.2.3 was installed with youre method) :
hostapd 1:2.3-1+deb8u3It had been months since I tried everything to change kernel,(but it was impossible without the old lines of manual commands). I have to break two three things, and badly to clean. It doesn't matter, see you soon, good continuation Igor, and thank you very much for your work.
