By default channel 1 is used. Try channel 5. Channel 1 is notoriously bad. If that doesn't work, try channel 11.Other devices on the same channel might not play well with LNWI's unique format.
Also, you can get a free app for android. Wifi Signal analyzer. It comes with a history graph bar and analog meter dial. Select your units SSID, and where it drops out. It will tell you the signal strength.

Have you tried a different cell phone to control the train. I suspect either a cell issue or a defective LNWI...

Hello
I have an older digitrax system db150 and dt300 throttle. I purchased the LNWI and followed directions and setup was easy and at frist it seemed to be working great. I am using moto Z froid phone and the engine driver app on android 7.0Now I am having the issue of it disconnecting from server while running trains. I have contacted Digitrax and followed their directions of reseting the db150. I am still having the issue and would like to know if anyone else has has any issues with the lnwi. I am not sure if I am getting interference or something in my train room. I like it when works but having to shut down the system and restart everytime I lose connection is not fun.
