To more appropriately maintain a wireless communication connection, a communication apparatus obtains an identifier of a first network connected, by a first wireless communication scheme, to another communication apparatus; searches for a second network by the first wireless communication scheme, which exists on the periphery, and obtains an identifier of the second network; and transmits, if the identifier of the first network and the identifier of the second network are different, a predetermined notification signal to the other communication apparatus via communication by a second wireless communication scheme with lower transmission power than the first wireless communication scheme.
