A network apparatus has a wireless communication unit wireless-communicating with a network apparatus, a connection control unit controlling the wireless communication unit based on connection data to establish connection with the network apparatus, a first storage unit storing first connection data for establishing connection with a first network apparatus, a second storage unit storing second connection data for establishing connection with a second network apparatus, a recording control unit recording the second connection data into the second storage unit when the connection control unit establishes connection with the first network apparatus, a test unit trying to establish connection with the second network apparatus when the connection control unit cuts off the connection with the first network apparatus after the recording control unit records the second connection data, and a return control unit re-establishing the connection with the first network apparatus after trying to establish connection with the second network apparatus.
