TUI & Wifi worked fine for one week, now won't.

Kenny,

Try using a different cable between the TIU and the WIU.

Update: After an evening of not being able to get the wifi to pick up my TIU (white light) ( green & blue on), I turned power to whole system off. Let it set turned off, while I slept, 8 hours later, turn the power back on and system starts up wifi blinking several lights and get my (white, green, blue lights all on! Working fine. This is the 2nd time this has happened. 

I will try another USB cable to the TIU !

Not sure about you but I have to turn my TIU unit on for at least 30 sec before I turn on my WIU on or it doesn't find it  Powering them on at the same time will result in failure everytime. 

Thanks Matt, I'll try that.

2nd Update: As said earlier, if I leave power off for the night, and then retry, everything comes on TIU is found, works great. Turn it off, and it will not come back on! Only get a green power light and a solid blue wifi light on, NO white TIU light on the wifi unit.

Barry, I tried a second USB cable. Matt, I tried to turn only the TIU unit with power on for minutes, then put power to wifi unit same results. Wifi green light and blue light, but no white light needed to run the system.

IF I get it to come on again, I plan on leaving the wifi and TUI aux powered on and just shut the 2 MTH Z-100's off that supply power to my 2 fixed tracks.

I'm wondering if something is wrong with my TIU, but when it on, it runs 4 trains just fine.

Hi,

Make sure the red light inside the WIU is on. Also, is there power going into the FIXED IN 1 Port of the TIU? Hope this helps.

Ricky, I have fixed power into port 1 + 2 plus aux power going in as well. The TIU red light is on and both tracks have the trains lit up.

3rd Update : I came home after having all power off for hours. Turned it on and the wifi started blinking and I got my green, blue and white light to come on. Ran the 4 trains on two tracks flawlessly for a half hour. I have now hooked up a separate switch to the aux power hook up to the TIU and wifi, which I plan to just keep on. Another switch turns my 2 MTH Z-100's off that power fixed port 1 and 2. I plan on just keeping the wifi and TIU powered up, since I have so much trouble getting it to come back up correctly.

Hi,

Ok. Good. I keep mine on all the time and I never have any problems. Glad it works.
