Dang .... the last time I bought one (2 years ago) you could get a top of the line Router for under $200. Are doctors making them now?????
It's all marketing hype and brands paying for reviews. The vast majority of these reviewers should be ashamed of themselves pushing this overpriced crap.
The brand new "Model 5400" with aggressive gaming style is 3X faster then our previous Model 1750 as long as you ignore the following
A) you need to drop another $350 plus for the exact same router so you can operate them in bridge mode to get the maximum link speed which is still a percentage of the Marketing link speed since you can only connect to one radio on one band at a time.
B) the big numbers are meaningless as they are just adding more radio signal numbers together and you won't connect any better then your 1200-1750 AC router.
C) better link connection does not always mean better throughput
D) the range still sucks meaning your 5400 router will perform the same or better as an AC 1200 once you move ten feet away or put a wall in-between you and the router.
E) The vast majority of mobile clients are 2X2 1200 AC or lower
F) The eXtreme Gaming mode QoS and SUPER DUPER 4K HD QoS is actually the exact same QoS in all the other routers released for the past several years just with a new name.
G) a $5 Ethernet cable plus 100mbps port still gives you a more stable connection and a gigabit port & cable still outperform the wi-fi speed of the router plus give you a more stable connection.
H) A powerline adapter and an old router turned into an Access Point (real easy) outperforms all these $400+ mesh units.
I) It still won't make your 25-30 mbps "triple play" connection any faster.
P.S. Check out the Asus AC66 B1 router; exact same internal hardware as the Asus AC68U 1900 AC router but is sold as an AC1750 for marketing purposes. Uses the same dual core CPU as the Netgear 6400 (I own bot the netgear and AC 66U B1), USB 3.0 port, and smaller foot print. I find the Netgear routers rather big for the4 family living room.
Good article on the current state of routers and their marketing hype
