First, unplug the appliance. Second, take a pen or an unfolded paper clip, and insert it into the reset hole in the back of the appliance. Hold the reset button in while plugging the appliance back in. Be certain to continue to hold the reset button in until the amber wrench light on the front of the appliance stops blinking. At this point, you've reset the appliance to default settings. the default IP address of the appliance is 192.168.168.168
Hope this helps.
