I'll agree. There is a strange odd thing about Samsung when the date/time is off. Be sure to check that. Also, set the DNS to 8.8.8.8.
If that fails, make it a Samsung issue. They fix or refund for the lost feature. I think it's about time that Samsung ditch Smart Hub logins or start handing out Roku's.

I have a 1 year old 55" Samsung Smart TV. I have been having problems streaming Netflix and Amazon Prime movies through the Smart Hub app as they keep buffering. Attempts to solve this problem include having Time Warner replace my modem and router and moving them to the same room as the TV; getting Time Warner to replace the line from the pole to my house; Getting Time Warner to work on splitting our service at the pole as too much congestion on our line causes slow Internet speed at busy times. Currently I have a strong Internet connection at 33 mbps all the time. Here is the interesting thing.... I can put my Apple TV Box on my TV and stream everything through that with no trouble at all... no stalls, no freezing, no buffering. This makes me think it has something to do with the Smart Hub.
