A network apparatus capable of automatically configuring connection polarity includes a random number generator of a plural order for generating a plurality of random numbers, and a plurality of connectors each of which is connected to a corresponding network cable. Each of the connectors includes a signal detector for detecting a network signal, for example, a fast link pulse or a normal link pulse from the corresponding network cable, and a polarity configurer coupled between the signal detector and the random number generator for selectively changing a connection polarity of a connector thereof in accordance with one of the random numbers generated by the random number generator when the signal detector fails to detect a network signal from the corresponding network cable.
