I couldn't be happier with the router. I think it to be a shame that the stores they are sold in give inaccurate information regarding the performance capability just to sell other products which probably aren't necessary for most.
Bought a 4k tv, my ISP's router could not stream the video - it buffered. The sales tech suggested the Nighthawk 2300 and to connect it to the ISP's box. It worked! Now I have wifi and can stream movies, games, etc.
