PROBLEM TO BE SOLVED: To provide a network repeater that can easily be found out, even when it is placed at the outside of a visual field. SOLUTION: A main body 2 of the network repeater is provided with a buzzer section 8, whose buzzer is in operation according to the notice instruction from a buzzer instruction device 1. In the case that an operator uses a buzzer instruction section 4 provided to the buzzer instruction device 1 for instructing the buzzer section 8 to raise a notice, this notice instruction is transmitted to the buzzer section 8 via a network cable 3 and an instruction reception section 7 to activate the buzzer. Thus, the operator can easily find out the repeater, even when the main body 2 is placed outside of the visual field.
