A communication apparatus receives a signal that requests for communication parameter(s) from a first other communication apparatus that connects to a wireless network by using the communication parameter(s), determines whether or not the communication parameter(s) have been provided to a second other communication apparatus that constructs the wireless network, upon receiving the signal, and notifies the first other communication apparatus of the fact that the communication parameter(s) have not been provided to the second other communication apparatus in a case where it is determined that the communication parameter(s) have not been provided to the second other communication apparatus.
