I don't know if this will help you . . . but when I first connected to the T-Mobile tower, I couldn't connect to my TV because of the password issue.  I went to the settings on the TV, chose Wi-Fi connections and typed in my network password.  I think I had to do that the second time I wanted to stream on the TV, too, but never again. Now, my password was actually what it had been when I had Cox, because I was using the router I used with Cox, not using the T-Mobile gateway as a router, only as a modem. If you are using it as a router, you would have to type in your T-Mobile network password.
