Let's start with the most common. Is the date/time right on the Netflix player (TV, BD player, etc.)?
After that we look at router settings, etc. Yes, the internet can work and we still need to check things. Please don't stop looking at the other areas if the internet works. One member took 40 posts to check the time.
When I click on Netflix it loads for 10 seconds and then it takes me back to whatever channel I was watching on my panasonic why doesn't Netflix work and i know it is not Internet connection because the other apps work
