1. A wireless quality degradation factor detection method comprising:
a spectrum generation step of generating a spectrum based on a received radio wave;
a reception level detection step of detecting a reception level of a desired wave based on the generated spectrum;
a determination step of determining whether or not information about the generated spectrum includes a factor that prevents quality of the received radio wave from being maintained based on a determination criterion specified in advance, wherein the determination step includes determining whether or not the detected reception level of the desired wave is less than a predetermined value;
an identification step of identifying the factor based on a result of the determination and the determination criterion, wherein the identification step includes identifying based on the determination step determining that the reception level of the desired wave is less than the predetermined value, a low reception level of the desired wave as the factor that prevents the quality of the received radio wave from being maintained; and
an output step of outputting information representing the identified factor.
