A communication apparatus may determine whether a first external apparatus is a target apparatus by referring content of a predetermined area included in a first connection request, in a case where the first connection request is received from the first external apparatus via a wireless interface, under a state where the communication apparatus operates in a first operation mode, and establishes a first wireless communication with the first external apparatus in a case where it is determined that the first external apparatus is the target apparatus. A wireless communication with the first external apparatus may not be established in a case where it is determined that the first external apparatus is not the target apparatus. The communication apparatus may store setting information in a setting area in a memory in a case where the setting information is received from the first external apparatus by using the first wireless connection.
