A communication apparatus is provided that establishes a wireless LAN communication by handover. The communication apparatus communicates with an external apparatus through a first communication path. The communication apparatus includes a storage unit that store a communication parameter used for communicating with the external apparatus through a second communication path, a communication establishment control unit that performs control to establish communication with the external apparatus through the second communication path using the communication parameter stored, and a communication parameter change control unit that performs control to change the communication parameter stored in the external apparatus that establishes communication through the second communication path. The communication parameter change control unit prohibits change of the communication parameter stored in the external apparatus that establishes communication through the second communication path when the communication through the second communication path is established by switching from communication through the first communication path.
