1. A method of selecting an access point for a communication device, wherein the communication device supports at least one frequency band, the method comprises:
(a) monitoring a channel of the at least one frequency band;
(b) calculating a first count that the channel is detected to be in an occupied state;
(c) calculating a second count that the channel is detected to have an ambient noise;
(d) repeating steps (a) to (c) to obtain the first count and the second count of each of a plurality of channels used by a plurality of access points;
(e) obtaining a plurality of received signal strength indications (RSSIs) of the plurality of access points, respectively; and
(f) selecting a target channel from the plurality of channels and a target access point from the plurality of access points to perform connection according to the plurality of RSSIs and the first count and the second count of each of the plurality of channels.
