Abstract:
1. An apparatus comprising: a connection unit configured to connect to a network; a switching unit configured to switch a communication speed when data communication is performed via the connection unit; a determination unit configured to determine whether the apparatus performs the data communication under a spanning tree protocol; a setting unit configured to set the apparatus to a normal mode or a power saving mode; and a limitation unit configured to limit switching of the communication speed to set a fixed communication speed in a case where the determination unit determines the apparatus performs the data communication under the spanning tree protocol, wherein the switching unit allows switching the communication speed in a case where the determination unit determines the apparatus does not perform the data communication under the spanning tree protocol; and wherein the switching unit switches the communication speed to a low speed in a case where the determination unit determines the apparatus does not perform the data communication under the spanning tree protocol and the setting unit sets the apparatus to the power saving mode.
