netflix is a 100% internet web site , streaming site. thus the net in flix. what did you mean by hooked?\ do you have internet at home at all? do other things in home work to the internet, like PC or cell phones. what I can not under stand is (different room) this phase implies some rooms do work (netflex) and wifi gets weak if my move any TV farther from the home router and will fail past 25 feet or more. wifi is super weak through walls for sure brick, or 2 walls. if home is small one wifi access point is all you need if huge home more. distance matter, TV to router. no TV model # told. (tells me wifi spec) if you said my TV works in room 1 but not room 2, wifi;. it be super more easy to answer.. is this true? if true , get a tech to upgrade your wifi. or go wired, Ethernet.(a better home upgrade)
