A communication apparatus includes a first communication unit, a second communication unit, and a communication-apparatus-side controller. The first communication unit wirelessly communicates with plural terminal apparatuses, the number of which is less than or equal to a predetermined maximum number of connections allowed. The second communication unit wirelessly communicates with a connection-requesting terminal apparatus that attempts to wirelessly communicate with the first communication unit. The communication-apparatus-side controller transmits, to the connection-requesting terminal apparatus via the second communication unit, information indicating that wireless communication via the first communication unit is not available in a case where the number of connections established for wireless communication via the first communication unit has reached the predetermined maximum number of connections allowed.
