Last hope for NetFlix and my Blu-Ray player

[aznav]

I have called every 800 number available. I have written Apple Discussion, I have called Comcast, Samsung, and my local Apple dealer. No help. They just read from a computer a response that I have by now memorized. I'm about to send my new Samsung 2500 back to Amazon.
Here's the deal: After hours of fidgeting, I have finally figured out that I can either stream NetFlix or get internet for my computers but not both. Period. I am somewhat techno impaired but in some of the discussions someone mentioned that you cannot have two IP addresses for one cable OR you cannot have one IP address and run NetFlix and surf the web on your laptop. The second seems absurd. In the very fine print, Samsung says that some IP's will not let you stream NetFlix. Does anyone know if that is true with Comcast? Comcast themselves didn't know (honest! - at least not the boiler plate email I got back said they didn't). It honestly starts to get funny when I go through all the set up online with my Samsung and then they give me a password to start streaming movies. BUT, to do this, I must disconnect my Samsung to get online with my laptop to plug in the password. By the time I do that, the password time has expired! LOL!!!!! Besides, I don't even think it would work by the time I switched back to "live" NetFlix.
