Leave about ¼ inch (6 mm) of each screw protruded from the wall so that you can
insert the screws into the holes on the bottom of the router.
5. Line up the holes on the bottom panel of the router with the screws in the wall and
mount the router to the wall with the cables either at the left (see the left figure) or
right (see the right figure) of the router.
