Smart TV wifi connection

I have a new Tmobile 5G wireless router, just came out last week. 
My LG OLED television is not connecting to the home network. Can anyone help please? 

I could not connect to my Sony TV at first after getting T-Mobile internet.  Had to go to the settings on the TV, choose network, choose Wi-Fi, pick my network and type in my network password.  I had to do that the second time I wanted to stream, too, but never again.  I am using the eero 6+ routing system, though, not the T-Mobile gateway alone.  All I had to do was connect the eero to the T-Mobile tower with an ethernet cord, nothing more. My network name and password stayed the same, but I still had to type in my password at first to use various devices.
