I recently purchased a Samsung 63" plasma TV with a Samsung blu-ray player in order to receive Netflix streaming movies. On occasion while watching the movie/tv series will stop & it appears to then re-boot & then it will continue. I have a basic router with 2 computers in my computer room upstairs with the plasma TV downstairs in the den.Quality bars show between 50%-75% on Netflix indicator before retrieving program. Is this caused by router & what is best router to buy to remedy situation please?

50 to 75% sounds like you have a big house or a weak router. Other interference can be if you have an internet telephone or other high band sucking device. You should first increase your signal with a better router, amplifier, or repeater which for home use don't cost a lot anymore. Also check your QOS settings if your router has them to prioritize the Blue-Ray player.

Best I can do.

Will N300 netgear have enough speed to stream movies on line?

Will N300 netgear have enough speed to stream movies on line?

Yes and no. Mostly its going to depend on what type of internet service you have and what is connected to that service. The pipeline width of the router is plenty but you can't put out more then you take in.
