Ditto. Streamed all day (don't judge me...it was raining) on my PS3 with no issues at all.
Given his issues that appear to be only Netflix, I'm guessing it's something between him and Netflix (or the Netflix servers he's connecting to). To xcrunner529, there's a lot of internet between your house and Netflix, so it could be Netflix, the ISP, or anything in between. It could very well be something with whatever Netflix server farm you're connecting to and the CSR you're talking to has no idea (they're just first level support). It could very well be they aren't even having issues but the traffic is hitting a bad hop somewhere along the line before it gets to you. Your connection to any given website/service will only be as fast as the weakest link, of course.
Where are you located at?
Regardless, glad it's not me.
