Claim:
1. A first communication apparatus for performing wireless communication with a second communication apparatus, the first communication apparatus comprising: a memory storing a predetermined wireless setting, which is assigned to the second communication apparatus; a work memory; and a processor communicatively coupled to the memory, the processor configured to execute instructions which, when executed, cause the first communication apparatus to: store a current wireless setting in the work memory; output a communication confirmation by using the current wireless setting; determine whether a first response to the communication confirmation has been received in a predetermined time period; if it is determined that the first response has been received in the predetermined time period, perform wireless communication with the second communication apparatus by using the current wireless setting and receive first target data from the second communication apparatus by using the current wireless setting; if it is determined that the first response to the communication confirmation has not been received in the predetermined time period, output a probe request and determine whether a second response to the probe request has been received; if it is determined that the second response to the probe request has not been received, maintain the current wireless setting; if it is determined that the second response has been received, further determine whether the second response to the probe request includes a particular service set identifier (SSID) including a specific character string corresponding to the predetermined wireless setting stored in the memory; if it is determined that the second response includes the particular SSID, establish wireless communication with the second communication apparatus by using the predetermined wireless setting and receive the first target data from the second communication apparatus; and if it is determined that the second response does not include the particular SSID, maintain the current wireless setting.
