Abstract: A wireless access point system includes a wireless access point (WAP) apparatus, a location-setting module, and a portable electronic device. The location-setting module stores a location list recording a location and an optimum direction corresponding to the location. The portable electronic device has a detection mode and a connection mode. In the detection mode, the portable electronic device controls the WAP apparatus to radiate a wireless signal and change the radiation direction within a specified direction range. The portable electronic device analyzes the wireless signal to obtain the optimum direction having an optimum signal receiving strength, so as to update the location list with the optimum direction and the location corresponding to the optimum direction. In the connection mode, the portable electronic device loads the optimum direction corresponding to the location and controls the radiation direction to be adjusted as the loaded optimum direction.
