I’ve had it set up for quite some time... and use it.
What I don’t understand is how I use it without cable. I have it installed as one of my apps on Spectrum.
Connect it via WiFi to your home network. It will walk you through the network setup. Then install the apps you want and, if you have an account, sign in with your username and password. They actually make it a LOT easier these days because you can use a computer, phone or tablet on the same network. They give you a URL to go to. Then you enter the code from the tv screen in the computer, phone or tablet and away you go.
You set it up through your internet router. It hasan ip address so all you need to do is when it tries to connect to your network, enter in your network password and it should connect right up.
