He's right but if you are connecting the box through wifi you need to put the password for your network on the box. The TV doesn't have to be connected to the network for it to work. HDNI from box to TV, input to the HDMI port you used such as #1, box plugged in and turned on and you should be at the opening screen. This is where you go into settings make sure wifi is turned on and enter the password.
The tv screen said "no network" when I was trying to set up the Ss box and the box wouldn't let me go any further...I'm about done with this whole thing...
