My network was crashing and lagging constantly. After juggling 3 old routers and trying setting up extenders or dual networks I decided it was time to upgrade finally. What once worked was failing as my family and technology grew. Essentially I had too many wireless devices. This nighthawk fit the bill exactly and is handling my household perfectly. It is currently providing for 2 iPads, 2 iPhones, 2 android phones, 3 dlink cameras, 360, PS3, 1 appletv, psp vita, laptop, surface and Directv all wirelessly while also networked to two tplink 8 port switches that have about 10 devices hard lined, which on "game night" has 3 ps4's or xboxones playing online together. We are a gamer family and this nighthawk has held up extremely well. I've had it for little over a month and no problems yet. Seriously recommend this and as with any router do the extended warranty as I've never heard of a router that doesn't fail with serious use, at least peace of mind on expensive equipment for cheap, believe I paid 19 for 3 years, which to me is a no brainer. Almost forgot, the iPhone/iPad app works great for maintaining your network and can even reboot remotely when adding on. 5ghz ac, 2.4 ghz, and guest networks of each. Range was huge upgrade over my old as well.
