A communication apparatus includes a first determination unit that, in a case where a use request for a wireless local area network (LAN) setting service has been received, determines whether a communication in a wireless LAN infrastructure mode is in execution, a transmission unit that, in a case where it is determined that a communication in the wireless LAN infrastructure mode is in execution, transmits information indicating that the wireless LAN setting service is unavailable to a terminal apparatus, and, in a case where it is determined that no communication in the wireless LAN infrastructure mode is in execution, transmits information indicating that the wireless LAN setting service is available to the terminal apparatus, and an activation unit that, in a case where it is determined that no communication in the wireless LAN infrastructure mode is in execution, activates the wireless LAN setting service.

An image reading apparatus includes a manuscript reader, a communication device, a distance determination device, a manuscript leaving determination device, a controller, and an approaching person determination device. The manuscript leaving determination device determines whether a manuscript is left in the image reading apparatus. The communication device performs wireless communication with a portable device carried by a user. The approaching person determination device determines presence and absence of a person approaching the image reading apparatus. The controller transmits, to the portable device, warning information indicating a risk of information leakage when the distance determination device determines that a distance between the image reading device and the portable device has reached a predetermined first threshold value and the approaching person determination device determines that there is an approaching person in a state in which the manuscript leaving determination device has determined that a manuscript is left in the image reading apparatus.

In a communication apparatus, a processor receives first and second requests from an external device via an internet. The first request has first port information indicating a first port. The second request has second port information indicating a second port. In response to receiving the first and second requests, the processor transmits first and second responses to the external device via the internet. After transmitting the first response and the second response, the processor receives result information from the external device via the internet. The result information is based on a fact that the external apparatus receives the first request and the second request; and performing an addressing process on a basis of the result information. The addressing process is for addressing a security issue concerning the first port and the second port.

An apparatus that executes a job, broadcasts a wireless signal prior to establishing a connection by wireless communication with an external apparatus. The wireless signal includes information relating to the apparatus, by which it can be identified whether execution of a job by the apparatus is possible, in a predetermined packet.

A non-transitory computer-readable medium storing a computer program readable by a computer of a communication apparatus, the computer program causing the communication apparatus to: when first trigger information for establishing first wireless connection is received, supply a first connection instruction to a first wireless interface and store device information into a memory; when second trigger information is received, supply a second connection instruction to the first wireless interface; and in a specific case where it is not possible to re-establish first wireless connection with the external apparatus, display, on a display, display information for re-establishing the first wireless connection with the external apparatus. The display information includes first display information in case the device information is first device information, and second display information in case the device information is second device information.

An information processing apparatus includes an interface and a controller. The interface performs power delivery and communication with an external apparatus. The controller performs: storing, in a memory, history information relating to power delivery performed with the external apparatus through the interface, the history information including identification information of the external apparatus and a power role of at least one of the information processing apparatus and the external apparatus, the identification information and the power role being stored in association with each other, the power role being one of a power source of supplying power and a power sink of receiving power; and in response to detecting connection of the external apparatus through the interface, determining the power role of the information processing apparatus based on the identification information of the external apparatus connected through the interface and on the history information stored in the memory.

An image forming apparatus, to which terminals are connected, comprises an image forming unit, a detector that detects an error, and a controller that, when the error is detected, specifies a portable terminal through which an operation to eliminate the error is requested, transmits a request to the specified terminal, and transmits a notification that notifies of an occurrence of the error to each terminal other than the specified terminal. The terminal that has received the request displays information representing an error type and information promoting an elimination of the error, and the terminal that has received the notification displays not the information that promotes the elimination of the error, but the information representing the error type.

A CPU of an MFP receives battery information from a first external device via a first interface, determines whether a total amount of electric power supplied to a plurality of interfaces from a power supply is maintained, and reduces an amount of the electric power supplied to the first external device via the first interface in a case where determining that the first external device has no battery based on the battery information in response to determining that the total amount of the electric power supplied to the plurality of the interfaces from the power supply is not maintained.

An apparatus that executes a job, broadcasts a wireless signal prior to establishing a connection by wireless communication with an external apparatus. The wireless signal includes information relating to the apparatus, by which it can be identified whether execution of a job by the apparatus is possible, in a predetermined packet.

A system for tracking the location of an electronic device includes an electronic device and a wireless location tag. The wireless location tag includes a microcontroller unit, and a modular connector interface configured to be communicatively coupled to a port of the electronic device. The wireless location tag is configured to establish an Internet connection to one or more backend electronic devices in response to detecting that the wireless location tag has been communicatively coupled to the port of the electronic device, obtain identifying information that is associated with the electronic device, and identify tag identifying information associated with the wireless location tag. The wireless location tag is also configured to send one or more instructions to the one or more backend electronic devices via the Internet connection, and send one or more ping messages to the one or more backend electronic devices.
