I've been operating my layout using the DCS wifi for about four months now, with no problems. When I attempted to run trains tonight, it wouldn't work. Using my iPad I selected the MTH wifi, I turned on the z4000 and set to 18 volts. Then I selected the MTH icon on my iPad and refreshed, after a few seconds a message came on the screen saying timed out. I noticed the purple TIU light on the wifi was flashing. I unplugged the power to the wifi and powered it back up after a few minutes. I was able to run trains for a few minutes, then the TIU light started flashing again. I picked up the trusty old handheld controller and everything worked fine. What could it be?
