Samsung TV will not connect to Tmobile

I am having the same problem, my samsung TV is not accepting my password 

Did anyone get a resolution for this?  I cannot get my tv to accept my password, either.  It did once and worked for awhile, then someone else did something and now it won't work.  I have reset both the modem, the network, and the tv to no avail.

Same issue

Answer?

Creating a second 5g network with WPA/WPA2 called TV fixed this issue for me right away once I reset the network on the TV.
