PROBLEM TO BE SOLVED: To provide a technique enabling the execution of radio communication using appropriate setting information.SOLUTION: A multifunctional device 10 transmits PING to a communication device 70 using designated setting WS2 when setting information to be used at present is the designated setting WS2. When no response to the PING is received, the multifunctional device 10 determines that communication is not executable (No in S4). Subsequently, when an SSID included in initial setting WS1 is received from the communication device 70 (Yes in S14), the multifunctional device 10 changes the setting information to be used to the initial setting WS1. If the SSID included in the initial setting WS1 is not received from the communication device 70 (No in S14), the multifunctional device 10 maintains the setting information to be used in the multifunctional device 10 to the designated setting WS2. |
