Anyway, wifi cant be completely disabled without calling their support and I bet they are using wifi direct. I have it blocked now on router (which is anyway configured that unknown macs cant connect) but I wonder what can a normal ordinary user do.
Also you cant enter into factory menu without remote control with number buttons that is NOT shipped with TV.
This is my last smart TV (and last product from Samsung, phones included). Monitors only.
