I'm very sorry to hear that has happened, and I apologize for any inconvenience this may have caused you. In order for me to better help you, could you please provide for me the complete model code for this device?
Also, could you clarify when you're experiencing the buffer issue? Is it only when you're trying to watch a video, or is it whenever you're in the app?
I hope I can get this issue fixed for you!

I have a new Samsung 55" flat screen model series 6500. I was excited that it was "internet ready", but no matter what I do, when I get into some app, like YouTube or BBC America, it comes up but then that damn buffering "spinning wheel" stops it every few seconds. I thought it was an issue with my Netgear router that provides okay service in the house for my laptops and other Wi-Fi devices, like a Logitech Wi Fi radio, but not with this TV. So, I hooked up a LAN cable directly from the back of the Netgear router hoping this would solve my problem, but last night I tried to look at a YouTube video and every 3-5 seconds it stopped and buffered. Any ideas? Any help? Is there some sort of upgrade that would fix this?
