A server has a communicator, a decision unit, and a communication control unit. In a case in which a first condition and a second condition are satisfied, the decision unit decides to cause a first client to stop data transmission. In a case in which the first condition and a third condition are satisfied, the decision unit decides to cause a second client to stand by for the data transmission. The first condition indicates that an access point to which the first client is being connected is the same as an access point to which the second client is being connected. The second condition indicates that a priority of the first client is lower than a priority of the second client. The third condition indicates that priority information has not been received from the second client.
