I get crzy I thought maybe I am connecting with another internet or my tv inside a ghost!!
but why in website of the Router the number of connection 1 not 2
becuase i use my mobile and my smart tv
An ethernet connection does not ask for a password.
Because it is a physical connection, direct to your router. It is presumed that the device is inside your home.
WiFi needs a password, because it could be your neighbor, or some random person outside.
