RB 133/C3 shutdown after normal reboot

Hello Forum

I have Mikrotik RB 133/C3, it works properly sometimes but another times it gives me hard time. i use cable length of 10 M Cat6 between the Mikrotik and the injector. i tried replacing the cable, injector and the Adapter and upgraded to the stable version 3.24 but actually it returns the same result. Please write bellow if you have faced this before.

Regards
Mikman
