A device includes: N communication modules, a selector that selects one communication module, an obtainer that obtains a reception strength of a signal, a generator that generates an image that includes 2N display regions associated with the N communication modules in order of communication speed from slower to faster per two display regions counted from a reference position along one direction, and a display. The generator generates, as the image, an image displaying (i) a graphic of a first type in, among the two display regions associated with the one communication module, more display regions counted from proximity to the reference position along the one direction, with an increase in the reception strength of the one communication module, and (ii) the graphic of the first type in each of two display regions associated with a communication module that communicates at a slower speed than the one communication module.
