A method of reducing power consumption in a portable router including a transmission power control unit controlling transmission power of Wi-Fi signals, the method comprising:

controlling Wi-Fi transmission power gain to a maximum power gain corresponding to a preset maximum power by performing a maximum power mode when power is supplied from the outside depending on determination as to whether the power is supplied from the outside based on received power information and operation mode information;
controlling the Wi-Fi transmission power gain to a power saving gain corresponding to a preset saving power by performing a power saving mode when the received operation mode is in a power saving mode in which the power is not supplied from the outside;
and
variably controlling the Wi-Fi transmission power gain according to a result of a comparison between cellular throughput and Wi-Fi throughput by performing a variable power mode when the operation mode is in the variable power mode in which the power is not supplied from the outside.
