I have the WIFI module and it was working and then when I went to run trains again it would not work. I sent it back to the train store and it worked for him. When I try to use it it tells me no active TIU but everything works fine with the handheld remote. MTH says it is a communication problem and it has something interfering with it. I also have a Lionel Cab 1 on the layout. I have no cordless phones in the house to interfere with the signal. Can anybody tell me how to fix this problem.
