I have been using Netgear routers since 1997. My 10 year old RangeMax needed to be replaced to achieve the bandwidth now available from my ISP [Comcast]. With a minimum of research it was clear that the R6400 was my best cost/benefit value. Easy setup via browser, 2.4 and 5 GHz speed and good coverage for a 2 story 3,000sf house. P.S. The Macintosh version of the Netgear Genie app is a little buggy on OSX 10.11.6 so I don't use it.
This is serving as wi-fi for a two story, 2500 sq ft home. Good coverage throughout. No dropouts. Easy setup. Speed and bandwidth have been good despite having 2 or 3 of our five kids online at the same time. Just using the basic functionality. I haven't used any of the special features. I recommended that my sister buy one. She did, and she's had no problems with it in her home. I think it's a good value in a midrange router.
Ever since I replaced the router given to me by optimum with our Optimum 100 package my internet download and uploads speeds have more than doubled! Keep up the good work, Netgear!
I have an R8500 at work as well and I am 100% satisfied with them both. I like the software access and the ability to manage who connects to the system. Speed is incredible. Would recommend to anyone, individual or business.
