An apparatus and method for efficiently performing power management for increasing reliable wireless signal transfer performed by mobile computing devices. In various implementations, a computing system includes a network interface and multiple components for processing tasks. The network interface sends, to at least a given component of the multiple components, an indication specifying the corresponding operating frequency ranges used by one or more radio modules used for wireless communication with an access point. The given component determines whether an operating clock frequency of the given component overlaps any of the received operating frequency ranges and associated harmonic frequencies. If so, then the given component changes the operating clock frequency to a frequency that does not overlap any of the received operating frequency ranges and associated harmonic frequencies.
