My htc one x is low wifi signal have to be no more than 3 or 5 meters from the router.
Accidentally touch the screwdriver into the part that is in red in the picture, when you touch the screwdriver threw sparks and since then the wifi signal is poor. Screwdriver touched the metal plate and one of the black boxes which is within the red circle
Any idea how to fix it?
