There are other issues such as the servers are not in the DNS (sorry but why the makers decided to use a technical system such as the internet is a find subject!) or the firewall is on in the router or modem (again why did the makers of these TVs select such a technical system?)
But at 1.x megabit, you will not be happy and should ask the person who said it was OK to accept the return.
I don't know who to be more annoyed with - Best Buy or Samsung. I purchased a 2012 46" Smart TV at Best Buy specifically to watch Netflix and HBOTOGO movies. I was assured that even though I live in a rural area that with at 1.0 MBPS or more I should have no trouble streaming.
First - the connection to my Smart TV is wireless through a Linksys (CISCO) router in my upstairs home office. My ISP is a local satelitte group that gets me 1.1 - 1.3 MBPS consistently.
I am able to connect the TV to the internet - it shows that its connected - it shows 4-5 bars of strength. But when I try to connect to Netflix or HBO TO GO it says "Network Interference" or "Please connect to the Internet".
I started with my ISP and for an additional $60/month I upgraded to a business band to get 1.5-1.7 MBPS - didn't help. I spoke with Samsung - they were spectacularly unhelpful - told me to "Reset" - when I explained that I had followed their Reset instructions four times with no success they said - "How strange - sorry that's all we can do."
I checked with Linksys who told me the problem was my ten year old 2.4 router and promptly sold me a dual band app enabled router for $170.00 - promised it would solve the problem immediately. No - it did not.
Finally I spoke with Best Buy tech support who tells me that without 5.0 - 10.0 MBPS I have no hope of EVER streaming movies reliably - end of story.
Is that true or is this TV just so glitchy that it will never work correctly? Does anyone have ANY suggestions to make this Smart TV....well, SMART?
