I haven't had any trouble with the ac2300 nighthawk .I've been using it for 2 months now, easy set up and haven't had any delay in my WiFi and there's multiple platforms being used cellphones Hulu/ Netflix Xboxgaming. I don't know how it compares to other brands and models but for me it's working sufficiently.
I love this router!!! We had purchased a different kind at first and it didn't work. So then we went and bought this one and we never have any problems now!
