1. Thread the male connector of the cable through the hole on the bracket, and use screws
(from behind the bracket) to secure the male connector to the bracket.
2. Change the angle of the antenna orientation from vertical to horizontal.
3. Attach the antenna to the male connector of the cable.
4. Attach the female connector of the cable to the router.
