I am talking to you from Australia. My smart tv did a system check, as it has done many many times. I then tried to connect to Netflix but it came up with the NW-*-* error. I have turned off everything, pulled plugs out of walls, waited ** seconds, then plugged back in. I then turned off the internet connection, pulled out plugs, waited ** seconds and then plugged everything back in. We do have internet connection, as my laptop is working and giving me my emails, google, news etc. It says on my tv screen "Couldn't connect to Netflix. Please try again or restart your home network & streaming device. For more information visit Netflix.com*nethelp , code nw-*-*. I followed the procedure (above) as suggested. I cannot get to the point to be able to reset it with username & password. Can you tell me what the problem would be ? It can't be our internet provider, as the internet is working.
