cant view devices in my app

Can't see my devices to manage access. Have restarted gateway as suggested but get the same gateway not responding message

My devices mysteriously started listing yesterday with no changes by me. We'll see how long it lasts.

 I’m still having “No devices found” on the T-Mobile app.  A third party IP scanner app shows the expected devices and 5 unidentified devices.   

  However, when I shift to my other ISP, those mystery devices are no longer showing.

(Note that I am running two ISPs -- trying the T-Mobile for better speed and “forever” cost)

My decades of use ISP (Frontier) is an unmeasured service. The rates have been creeping up-- but a call to "retention" gets me back to my original rates for a year. I am riding a dual-link DSL, with a promise of fiber "soon" (been hearing that for a couple of years).  A call for tech support generally gets a human being in the US fairly quickly.

  The two times I somehow got past the T-Mobile 'bot to get a human being, I got India (I think) and the Philippines. The Filipino lady was speaking english very well.

   Frankly, right now the lack of transparency by T-Mobile has me seriously contemplating ending the experiment.  And yea I've heard the stories of "lost" returned routers --- which means the "experiment" might cost me another $350ish upon quitting. ---- still contemplating.

My apologies, I am referring to a factory reset of the gateway. However, even connecting the Amazon Echo on a separate wireless router is no longer working for me. Moving the Firestick works fine, but  Alexa causes the 500 error when trying to list devices no matter what. However I can still open the T-Mobile app. Please post updates or more questions. Gracias.

  When you say "reset", do you mean shut it down -- wait a bit -- turn it back on?  Restore to factory and do the entire install thing again?

Or do you mean something else?

I can turn the fire tv off and it works, but he Amazon Echo just killls it and i have to reset the gateway in order to see devices. 

I get error 500 its when fire tv cubs are on

Turne them off i can see devices
