Non-transitory computer-readable medium for communication device, and method performed by communication device
Computer-readable instructions stored in a non-transitory computer-readable recording medium may cause a communication device to acquire predetermined information from a first interface under a state where a number of child stations participating in a first wireless network in which an external device operates as a parent station is equal to an upper limit, shift an operation state of the communication device to a parent station state from a specific state so as to form a second wireless network in a case where the predetermined information is acquired from the first interface, and supply a first predetermined instruction to an OS program. The first predetermined instruction may include an instruction for causing a second interface to send a participation request to the external device.
