A desirable connection form in consideration of a radio wave state is caused to be formed among three or more communication apparatuses. Group list information indicating three or more communication apparatuses, including local equipment, that have been set as a group for performing wireless communication is referred to so as to grasp communication apparatuses that have been set as the group. Then, a value indicating a degree of stability of communication between respective communication apparatuses indicated in the group list information is obtained, and a new connection form to which a change is desirably performed is determined by using the value indicating the degree of stability of communication between the respective communication apparatuses. Then, processing is performed for changing a connection state of respective communication apparatuses included in the group to the new connection form.
