Pimax crystal sound poping and mic not working screen flickering

so something really weird , i usually park my crystal on the desk by my router and when i do i sometimes hear cracking from the speakers and i thought it was just shutting down or something but today i put it there and noticed every time i put it close to to router it flickers the screens and the speakers do the popping sound and eventually the sound from the headset stops working at all , how whats going on with the crystal where it cant be close to a router ? despite all of this the mic always turns off after a while of using it and gets very frustrating
