1. A method comprising:

  • when a wireless/wired communications interface is detected as a communications interface type of a device, detecting a connection state of the device as one of a wireless connection state and a wired connection state;

    when the wireless connection state is detected, determining a data transmission error rate of the device during operation of the device in a wireless communications mode;

    notifying a device user to couple a wire link between the device and a host device to switch the device from the wireless communications mode to a wired communications mode when the data transmission error rate of the device exceeds a pre-determined threshold;

    monitoring detected interference levels that increased the data transmission error rate to determine if the detected interference levels have subsided during operation in the wired communications mode; and

    notifying the device user to disconnect the wire link when the detected interference levels have fallen within an accepted threshold level to resume the wireless communication mode.
