A circuit assembly for indicating statuses of a network includes an indicator circuit having a first indicator and a second indicator, a networking chipset including a first port for outputting a network type signal, a second port for outputting a linking status signal, and a third port for outputting a data transfer signal, and a driving circuit. The driving circuit includes a first transistor, a second transistor, and a power supply is capable of powering the first and second indicators. The second indicator is connected between the power supply and the third port to indicate data transfer status of the networking chipset. The first port and the second port are connected to the first indicator via the first transistor and the second transistor. The first transistor accepts the linking status signal to generate an assistant signal transferred to the second transistor. The second transistor accepts the network type signal, and compares the network type signal with the assistant signal to determine switching on or off the second transistor to control the indicator.
