Netflix no longer streaming

I have Arcadyan KVD21 Gateway and in central Kentucky. I got 5 bars and my speed is excellent. I don't understand how i could stream Netflix but not able to launch it.  every other streaming service work for me. ( I have different phone service provider (visible) ) as I mentioned before if I used my cellular hotspot to launch Netflix and on to my profiles then i went back and change my wifi to t-mobile home internet wifi and I was able to stream videos.
