Samsung will not upgrade your Tv to allow it to stream Netflix. They will provide a firmware update if there is a problem but they do not provide upgrades. What you purchase is what you get. To stream Netflix you will need to purchase a Blu-ray player with that function or something like the Popcorn Hour media streamer. Either way you will need to connect it to the internet either wired or wirelessly.
What I read Samsung has not yet supported this technology (Streaming to a Samsung LED 7100 TV). Is it prudent to purchase a Blue Ray Player or is this going to be available shortly. I am a Verizon Fio customer.
