Popping or crackling sound from wireless bass module

It's possible that interference from other wireless devices are affecting the wireless functionality of your product. Check for other wireless devices in the area of your product  (i.e. another router, cordless phone, wireless printer, smart TV, etc.). To determine if a device might be interfering, try unplugging its power cord or disabling Wi-Fi on the device. If the issue is resolved when a particular device is removed, try placing that device farther away from your product, if possible. Additionally, if the device has a wireless channel setting, try a different channel.
