Default [Q] Phone rebooting after turning on Wifi

I was using a stock rom on my phone.
So I installed Phoenix kernel.
The wi-fi won't turn on (but the phone didn't reboot).
So I installed AOSPA.
The phone started to reboot (Paranoid Android crash screen) after I tried to turn on the wi-fi.
So I installed Thunderzap kernel.
Still the same problem (with AOSPA).

What I should do now?
