A communication speed control circuit, provided between an external communication device and an information processing device, for controlling a communication speed of data to be transmitted and received via a network between the external communication device and the information processing device, includes a communication speed determining unit for determining the communication speed of a communication with the external communication device, a judging unit for judging whether or not there are data that should be transmitted and received, and a communication unit for receiving, if the judging unit judges that there are no data that should be transmitted and received when transmitting and receiving the data to and from the external communication device at the communication speed determined by the communication speed determining unit, the data from the external communication device at a communication speed lower than the communication speed determined by the communication speed determining unit.
