A game device is provided which can connect to a plurality of wireless controllers. A game device of the present invention has a plurality of communication modules, each serving as a master, which can wirelessly connect to slaves. One communication module performs an inquiry procedure for establishing a connection with a plurality of slaves, and the other communication module performs no inquiry procedure. The communication module that has issued the inquiry transmits, to a control unit, information relating to a slave that is not connected to the module itself, and the other communication module acquires the information from the control unit, thus obtaining information necessary for establishing a connection with a slave. This allows for quickly establishing a connection with a slave.

This invention concerns a network comprising a master and slaves. In the network, each slave figures out its performance values as performance parameters and transmits the performance parameters to the master. The master performs a process of selecting a backup master as a candidate for the next master, on the basis of the performance parameters transmitted from the slaves. The master supplies BM information containing synchronization information and the address of the backup master selected, to the slaves. When the master is removed from the network, the slaves determine the next master in accordance with the backup-master information. Thus, the slaves can be immediately connected to the next master.
