A hybrid wired and wireless communication device and a wired and wireless communication method thereof. The wired and wireless communication method includes determining whether a wired communication module has been linked to a wired communication network (72), setting a wireless communication operating mode of a wireless communication module to an infrastructure mode when it is determined that the wired communication module has not been linked to the wired communication network (74), and setting the wireless communication operating mode to an ad-hoc mode when it is determined that the wired communication module has been linked to the wired communication network (76). Therefore, the wireless communication operating mode is automatically set according to whether the wired communication network has been linked to the wired communication module, thereby increasing a user's convenience.
