• a communication unit configured to establish connection for communication between the information processing apparatus and the external apparatus;
• a determination unit configured to determine whether or not the communication between the information processing apparatus and the external apparatus has properly been performed from the time the connection is established until the time the connection is disconnected;
• and
• a control unit configured to, in a case where it is determined as a result of the determination by said determination unit that the communication during the connection has not properly been performed, have the communication packet storage unit maintain the communication packet that has been transmitted or received between the information processing apparatus and the external apparatus from the time the connection is established until the time the connection is disconnected.
