The Boost devices report to the T3200M as ethernet devices, not wireless. This may affect how they are presented in the App. Best to do as you indicated, use the direct connection to the router.
Thanks, likely the case -- I also found a web app that responds to the Boost IP addresses and provides a great view of what is going on in our WifI network. T3200M WiFi radios are shut down -- Booster mesh works great, now I will leave well alone!
