The invention relates to a method for managing the interference generated by the simultaneous operation of a wireless network using frequency-hopping spread spectrum and a wireless network using a spread spectrum technique, in which a set-top box has a wireless network using frequency-hopping spread spectrum and is connected to a residential gateway having a wireless network using frequency-hopping spread spectrum and a wireless network using a spread spectrum technique and in which, if the residential gateway and the set-top box are close, the residential gateway (E40) relays the data between the set-top box and the peripherals connected to the wireless network of the set-top box and the set-top box interrupts the operation of its wireless network using frequency-hopping spread spectrum.
