forgive my ignorance.....but i do need a little coaching. We like to watch netflix through wireless blu-rays, and previously we could only watch 1 tv at a time. My old router crapped out on me a couple days ago, and i replaced it with a n600 dual band.........thinking, 2 bands will let us watch on multiple tvs. sounds easy enough. well i get home and none of our devices can see the 5ghz band. none of the blu rays, the laptop, and none of our iphones. i can't find any settings that would seem to help either. do i have some options here....either with settings, or some extra hardware, or are my devices just 2.4ghz and that's just how it is?
