Patent ID: 8547944

Claim:
A wireless communication apparatus comprising: a receiving unit that receives a wireless communication parameter from a parameter-providing apparatus; a storage unit that stores the wireless communication parameter received by said receiving unit; a first detecting unit that detects a connection instruction for connection to a wireless network which is connected to by using a wireless communication parameter provided by the parameter-providing apparatus; a discriminating unit that discriminates whether a wireless communication parameter provided by the parameter-providing apparatus includes a dynamic component; a connecting unit that connects to a wireless network using a wireless communication parameter provided by the parameter-providing apparatus; and a determining unit that determines whether the connection instruction has been detected after disconnection from the wireless network has been performed in response to a user instruction, wherein if the connection instruction has been detected by said first detecting unit, (i) if said discriminating unit discriminates that the wireless communication parameter does not include the dynamic component, said connecting unit connects to a wireless network using the wireless communication parameter that has already been stored in said storage unit, and (ii) if said discriminating unit discriminates that the wireless communication parameter includes the dynamic component, said receiving unit receives a second wireless communication parameter, and said connecting unit connects to a wireless network using the second wireless communication parameter instead of using the wireless communication parameter that has already been stored in said storage unit, and wherein if the connection instruction has been detected by said determining unit after disconnection from the wireless network has been performed in response to the user instruction, said receiving unit receives a third wireless communication parameter, and said connecting unit connects to a wireless network using the third wireless communication parameter instead of using the wireless communication parameter that has already been stored in said storage unit.
