A first communication apparatus may repeat a broadcast transmission of a trigger signal via a second interface, which is a signal to be used by a second communication apparatus as a trigger for sending a wireless connection request to the first communication apparatus. The wireless connection request may be for forming a first wireless network to which both the first communication apparatus and the second communication apparatus belong. The first wireless network may be a network for performing a wireless communication via a first interface. The first communication apparatus may receive the wireless connection request via the first interface from the second communication apparatus which has received the trigger signal, and establish a first wireless connection via the first interface with the second communication apparatus so as to form the first wireless network.

An information processing apparatus includes a registration unit and a processing unit. The registration unit registers multiple terminal devices with the information processing apparatus or a different apparatus in association with multiple operators who operate the multiple terminal devices. The processing unit executes a process by performing, in response to an instruction for the process given by a specific one of the operators, short-range communication with a specific one of the terminal devices that is registered in association with the specific one operator.

A mobile terminal device can be used in a network system including a first network and a second network. Plural access points are connected to the first network. A common identification name is set to the plural access points. An access point having a coverage area overlapping with a part of a coverage area of the first network is connected to the second network. The mobile terminal device includes a detector, an execution unit, an acquiring unit, a connection controller, and a setting unit. The detector detects connectable access points. The execution unit executes an application which uses a network device connected to the first or second network. The acquiring unit acquires, from a history information memory, history information including (i) device identification information unique to the network device used when the application is executed in past, and (ii) device identification information unique to an access point.

A communication apparatus searches for a device by reading a two-dimensional code displayed by the device and notifies a user to use a direct wireless communication function of the device in a case where the device cannot be detected.

An information processing apparatus includes a controller. The controller changes, in accordance with an order in which images related to devices that have been identified are linked to each other, an order of priority in which one or plural cooperative functions that use functions of the devices are displayed.

An image forming apparatus is provided. The image forming apparatus may determine whether encrypted data may be transmitted or received between the image forming apparatus and one or more external devices, and determine a defect in security set to the image forming apparatus based on the determination.

A communication device may receive first specific information from a first terminal device, establish a second wireless connection with a second terminal device after the first specific information has been received from the first terminal device, receive second specific information from the second terminal device after the second wireless connection has been established with the second terminal device, determine whether the first terminal device is identical to the second terminal device by using the first specific information and the second specific information in a case where the second specific information is received from the second terminal device, disconnect the second wireless connection in a case where it is determined that the first terminal device is not identical to the second terminal device, and not disconnect the second wireless connection in a case where it is determined that the first terminal device is identical to the second terminal device.
