PROBLEMA Punto de acceso girando sobre sí mismo todo el tiempo

Hi all, I just received a new pro note 3 MIU 7 installed. Everything was fine, but now all the time truns hotspot on itself and off wi-fi! Sometimes, 1 minute shutting down back again! Has anyone else had this issue? I found a lot of ppl saying his point wi-fi access on and off but none of it turning on itself.
