My Wi-Fi connection to my Number One of Four TIUs went smoothly using the Quick Start Guide for the MTH Wi-Fi Network Mode. My Samsung Android tablet with the free app seemed to work as it should.
After downloading the $5 app upgrade for more engines and engine feature use, I attempted to connect to my Household Router with the MTH Quick Start Guide for Home Wi-Fi Network Mode. It didn’t work. Messing with the House Router caused it to change its ID and my husband lost his internet. An Emergency call to my son who is an expert in networking resulted in the following solution. Now I have an independent Train Router away from the House Router which will handle the rest of the modules that would be added to talk to all my TIUs.
Now I can proceed practicing running trains on my two main loops to discover whether I want to run with WiFi. (First I have to learn to keep my thumb and fingers clear of my Android tablet screen.)
See attached PDF document for "how-to".
Helpful tip: For longer life leave power on to Train Router when not in use>
