MTH Wifi Unit can't find TIUs

Today, I switched all the hook ups to my second TIU, but wifi unit still reads No TIUs Found. Could my wifi unit have gone bad? I still need help.

Do you have a dcs remote as well? Can it find the tiu?  

Is your device  set to MTH in your wifi settings?

Greg. Thanks for the reply. Yes, the remotes pick up the TIU no problem. 

Jeff, the WIU is set for MTH, not home. All I can think of is that the 9-pin serial to usb cable is bad, however, it is the same cable that I used to update the TIUs to 6.0.

Would love to know the answer as I'm having the same problem.  I've even changed the USB to serial cable and still no luck finding the TIU. 

I don't know if it matters for sure, but how is your TIU getting power? Don't go by the lights. Do you have it powered separately?

My TIU is powered via an external wall wart.   

I posted a week or two back on this issue. My I phone always finds the TIU.  My Android  started  TIU not found so I bought a @$50, 7in android tablet an it worked fine for  a week then started the TIU  not found.  There has to be a system issue somewhere, in all cases the setup of TIU, Wifi , aux power and track power were not changed. Just turned off and on for run sessions.

I had the same issue with my iPad.  I put an engine on the missing TIU track and started it with the remote.  The TIU magically appeared on the iPad after an application reboot.

Yeah but I don't have a remote any more. 

Sound dumb, not trying to insult anyone but make sure the device bluetooth is connected to the proper device. 

just like using your wifi on the phone. Seen people struggle with this and they simply overlooked connecting the device and application.

I have exactly the same problem with all my ipads and phones, my system is new so I didn't have to do any upgrades so I cant comment if the problem is in the upgrade

I have taken lots of screenshot pictures of the fault and I am in touch with MTH tech department

When I get the solution I will post it

I have had the wifi working months ago when I first got it. Just back to running locos and can't get wifi working. I have it set to mth. I connect on my iPad to the mth network using the default mthdcswifi password but it won't add engines. Connection times out and I think said no tiu found. Tiu is powered by. Z4000 and I see red light. My handheld works fine, sees TIU and all engines. I have a new TIU do I need to perhaps update the wifi software?the wifi unit is lit showing tiu connection but the app software under settings says no tiu connection. Tried on iPhone and iPad. 

do I need to perhaps update the wifi software?

I expect so, for two reasons:

• MTH says that you should.
• You're having problems that no one should even attempt to resolve until you're using the recommended TIU software.

I appreciate that but it’s frustrating  why something would work and then stop for no reason. The Wi-Fi  worked fine at one time. The TIU is new so I thought that was current with software. Anyway I’ll check the TIU and Wi-Fi to make sure both are current- the l process to update the Wi-Fi seems a bit more complicated but let’s see. 

I have been working on my layout for the last two months. Just this last weekend I finally get  a loop put together to run the Polar Express along with other engines. My wifi setup couldn't find the TIU either. My wife's son happened to be over and asked if I was hooked up to the network. I amused it would do this automatically but as it turns out I have to go into my settings on my iPhone (this is where yours and everyone's else's router in the neighborhood is viewed) every time I boot the system and select the MTH network to find my TIU. After that, train life is good.

I'm surprised so many of your are having such a fundamental issue.  We need to get to the bottom of it and get things resolved for all of you.  There is no reason we know of for you to be experiencing this issue given the current version of firmware in your system.  So, let's start with that.  Please be sure your gear is updated to the following revisions:

1. TIU -  v6.1
2. WIU - v1.1
3. App - v3.0.1

Once you are fully updated, if things still aren't working properly, reset each component.  I know it's a pain to reset the app if you have a lot of stuff loaded but, just export it and then import the image after the reset.  It's important to get your system to a point that is current and known.

TIU - Reset via the app or remote.  A feature reset should be adequate so you don't lose the TIU address.

WIU - Reset by holding down reset button (on top) for 10 seconds or more.

App - Reset by tapping "More > App Settings > App Reset"

There are some things you can try prior to the updates and reset that could be the issue but, given you guys are experienced, I doubt it.  Now, just because I said that, don't be embarrassed to come back and update us if it was a simple oversight.  I do it all the time.  The system is complex and has many elements.  It's really easy to miss a step.

Go to "More > App Settings" and make sure the app is set to DCS WIU.  (the latest version adds support for the Explorer and this setting may have gotten changed accidentally)

Go to "Settings > Wi-Fi" on your device and verify it is connected to the WIUs MTH network or your home network if you are in HOME mode.

Please report back here with your results.  Hopefully, we'll find the culprit in these steps but, have no doubt, the system is actually working fine and getting more and more stable with each app update.  We're working on a new update now with further enhancements .  It should be out in a couple of weeks.

In your case, 6.0 should be close enough.  So, if your other gear is up to date, try just resetting the WIU and cycle power on the TIU.  That is, power it down completely and then after resetting the WIU, power the TIU back up.  If you're connecting the WIU and TIU via USB cable remember TIU is powered by the USB so, unplug it as well.

What changed is that the app is a newer release than what you used previously.
