Frank, the Samsung documentation sucks, from my experience. I just picked up their flagship LCD model, and it does a ton of internet related stuff, but they don't bother to tell half the info that's required....
What model do you have? What menu features are internet related?
My TV has icons that take me to the various locations like U-Tube, etc.., and they are all on a screen that I access via the remote. I just went through all this, maybe I can help you out.
My model allows you to view the TV on the touch screen remote. Cool feature, cuz I can take the remote to the shitter or whatever.......... can also plug headphones into it.
But the documentation doesn't tell you that the TV has it's own network name - Link Share SEC or something like that - and the TV network and the wireless network, and the remote must all be on the network for them to talk and have everything work right..
